SpineZone is the latest health tech startup to raise millions in the musculoskeletal space

SpineZone is a startup that creates personalized exercise programs and treatment for neck and back pain. The company uses an online platform and in-person clinics to deliver a curriculum that, ideally, helps patients avoid the need for prescription drugs, injections and surgeries, and providers then avoid the cost of all of the above. Co-founded by brothers Kian Raiszadeh and Kamshad Raiszadeh, the company tells TechCrunch that it has raised $12 million in a Series A round led by Polaris Partners and Providence Ventures, with participation from Martin Ventures.

At its core, SpineZone is a virtual physical therapy platform augmented by in-person clinics. The latter bit is important because it takes a video repository, which has health outcomes baked into it, and helps get those same users some real-life support.

Patients can log onto the site, either through smartphone or laptop, and then answer a series of questions around pain and risk factors. Then, patients can go through a series of exercises. These exercises are created in tandem with professionals, and are based on peer-reviewed and evidence-based articles on musculoskeletal health.

Beyond this digital archive of videos, SpineZone offers an in-person clinic option to help patients practice these exercises. Off of this strategy, the startup claims that it has “1 million lives under management.”

SpineZone’s value proposition is that it helps payers and providers, whether that be employers, clinics or health plans such as Cigna or Aetna, avoid placing their patients in surgeries, which are expensive. By taking care of pain issues before they bubble up, SpineZone says that its current partners have been able to have a 50% reduction in surgery rate (it’s worth noting that COVID-19 could also play a role in this because it is high-risk to enter a medical facility).

Partners are happy because footing the bill of a non-operative procedure is remarkably cheaper than a non-operative procedure.

The cost saving that a medical center could endure can be in the millions. For example, the Sharp Community Medical Group saved $3.4 million in cost savings after working with SpineZone for two years.

SpineZone’s business model is a smidge more complicated than your classic SaaS fee. For example, it charges a clinic based on the number of members it serves per month, and also shares in the downside. For example, if SpineZone promises to get a clinic to $12 million in spend from $15 million, and the cost ends up being $17 million, the company will pay the clinic a portion of the difference. Alternatively, if SpineZone got the clinic to $10 million, even below estimates, it shares in the upside.

SpineZone joins a cohort of health tech startups that focus on musculoskeletal conditions. Venture-backed competitors include Peerwell, Force Therapeutics and Hinge Health, which was most recently valued at $3 billion, with plans to go public.

In order to win, many startups, SpineZone including, need value-based care to replace fee-for-service care. Value-based care is the idea that doctors are paid for outcomes instead of the number of times you enter a doctor’s office. The end goal is that this format creates monetary incentives around getting to an outcome faster: If a doctor is going to make $30,000 on fixing a knee, regardless of whether it takes two appointments or 20 appointments, they might as well do a more thorough job upon check-up instead of elongating the process. The flipside of this, of course, is that doctors might optimize for outcome volume and speed rather than the quality of the result itself.

While SpineZone’s early traction is promising, the healthcare ecosystem still has a ways to go before value-based models take precedence. Right now, Kian Raiszadeh estimates that 10 to 20% of revenue in a medical center comes from value-based care. SpineZone is projecting that it will get to 50% of revenue in the near future.

“And that’s the biggest evolution and tallest lift that we’re expecting,” he said.


Early Stage is the premiere ‘how-to’ event for startup entrepreneurs and investors. You’ll hear first-hand how some of the most successful founders and VCs build their businesses, raise money and manage their portfolios. We’ll cover every aspect of company-building: Fundraising, recruiting, sales, legal, PR, marketing and brand building. Each session also has audience participation built-in – there’s ample time included in each for audience questions and discussion.

Microsoft says China-backed hackers are exploiting Exchange zero-days

Microsoft is warning customers that a new China state-sponsored threat actor is exploiting four previously undisclosed security flaws in Exchange Server, an enterprise email product built by the software giant.

The technology company said Tuesday that it believes the hacking group, which it calls Hafnium, tries to steal information from a broad range of U.S.-based organizations, including law firms and defense contractors, but also infectious disease researchers and policy think tanks.

Microsoft said Hafnium used the four newly discovered security vulnerabilities to break into Exchange email servers running on company networks, granting the attackers to steal data from a victim’s organization — such as email accounts and address books — and the ability to plant malware. When used together, the four vulnerabilities create an attack chain that can compromise vulnerable servers running Exchange 2013 and later.

Hafnium operates out of China, but uses servers located in the U.S. to launch its attacks, the company said. Microsoft said that Hafnium was the only threat group it has detected using these four new vulnerabilities.

Microsoft declined to say how many successful attacks it had seen, but described the number as “limited.”

Patches to fix those four security vulnerabilities are now out, a week earlier than the company’s typical patching schedule, usually reserved for the second Tuesday in each month.

“Even though we’ve worked quickly to deploy an update for the Hafnium exploits, we know that many nation-state actors and criminal groups will move quickly to take advantage of any unpatched systems,” said Tom Burt, Microsoft’s vice president for customer security.

The company said it has also briefed U.S. government agencies on its findings, but that the Hafnium attacks are not related to the SolarWinds-related espionage campaign against U.S. federal agencies. In the last days of the Trump administration, the National Security Agency and the FBI said that the SolarWinds campaign was “likely Russian in origin.”

Six tips for SaaS founders who don’t want VC money

Over the past decade, venture capital has become synonymous with entrepreneurship. Founders from around the world arrive in Silicon Valley with visions of record-setting A rounds and billion-dollar valuations. But what if you don’t have unicorn dreams – or you don’t want to pursue VC money?

Bootstrapping a SaaS company is not only possible – I believe it’s a saner, more sustainable way to build and scale a business. To be clear, bootstrapping isn’t always easy. It requires patience and focus, but the freedom to create a meaningful product, on your terms, is worth more than even the biggest VC check.

I started my company, JotForm, in 2006. We’ve grown steadily from a simple web tool into a product that serves more than 8 million users – without taking a dime in outside funding. We’re profitable in an industry with big-name competitors like Google.

Most importantly, I still love this company and its mission, and I want the same for my fellow entrepreneurs. If you’re a SaaS founder who’s wary of VC funding, here are my best bootstrapping tips.

Keep your day job

Success stories from founders who leap blindly into business without resources or relevant experience are compelling, but they’re the exception, not the rule. Working inside another organization can build your skills, your network, and even inspire great product ideas.

After finishing college with a computer science degree, I worked as a developer for a New York media company. The editors always needed custom web forms, which were tedious and time-consuming to build. I kept thinking, “There has to be a better way.”

That daily frustration led me to start JotForm – but I didn’t leave my job right away. I stayed with the media firm for five years and worked on my product on the side. By the time I was ready to go all-in, I had the confidence, experience and savings I needed.

Many of the world’s biggest companies began as side projects, including Twitter, Craigslist, Slack, Instagram, Trello, and a little venture called Apple. If your day job doesn’t pay enough to fund the early stages of your business, consider a side gig or consulting work. There are so many ways to set yourself up for success without the pressure of VC cash or selling a chunk of your business.

Know you’re not alone

The exact numbers shift every year, but data compiled by Fundable show that only 0.05 percent of U.S. startups are backed by VCs. Another 0.91 percent are funded by angel investors. The vast majority, at 57 percent, are funded by credit and personal loans, while 38 percent get funding from friends and family.

It may feel like most founders raise multi-million-dollar rounds, but that’s simply not the case. It’s also good to remember that securing VC money is complicated and time-consuming. You can spend months taking meetings and presenting the perfect deck – and still leave empty-handed. Be patient and stick to your own path.

Measure profits, not popularity

SaaS founders often emphasize vanity metrics, like user acquisitions and total downloads. These numbers can measure short-term popularity, but they don’t reveal how users and customers feel about your product – or your long-term potential.

Retail Zipline raises $30M as it helps retailers adapt to the pandemic

When I first wrote about Retail Zipline in 2019, the startup was focused on building a communication platform that would help corporate decision-makers in retail communicate with individual stores. As you’d probably guess, the startup saw some changes in 2020.

“When COVID first hit, you might think a company that’s primarily focused on retail would be in trouble,” said co-founder and CTO Jeremy Baker. “But it turns out that a product that helps retailers communicate critical information when everything is changing is no longer a nice to have.”

In other words, where Retail Zipline might previously have been used for coordinating sales and promotions, it suddenly became a channel for managing things like health and safety protocols and communicating about furloughs and closures.

Co-founder and CEO Melissa Wong said the platform supports both engagement (a company executives sending a message to retail associates) and execution (translating a broader corporate strategy into an in-store experience). While you might think that execution was the only thing that mattered in the middle of a pandemic, Wong argued that the engagement side was also essential, particularly when employees felt they were putting themselves at risk.

“The engagement part means that we can explain to a retail employee what we’re doing to protect you during this crisis, and your role as part of this company and this brand,” she said.

She added that the company has doubled its customer baes during the pandemic and seen revenue increase 2.5x. Retailers using the platform include Sephora, AEO, L.L.Bean, Gap, Hy-Vee, Lush Cosmetics, BevMo, LL Flooring, Cole Haan, The LEGO Group, TOMS and Torrid.

The pandemic also spurred dramatic growth in e-commerce, but Wong (who previously worked on the corporate side of Gap and Old Navy) suggested that this won’t eliminate the need for physical stores. Instead, it just means they’ll have to live up to the long-standing “omni-channel promise,” where they serve as both a store and a distribution center for online orders.

“Retail will become more complex,” she said. “We will enable them to meet those complexities.”

Today, Retail Zipline is announcing that it has raised $30 million in Series B funding. The round was led by real estate-focused firm Fifth Wall, with partner Dan Wenhold joining the board of directors. Emergence Capital, Ridge Ventures, Hillsven Capital, Veeva co-founder Matt Wallach and the Fisher Family Fund also participated.

The company has now raised more than $39 million, according to Crunchbase.

In a blog post, Fifth Wall wrote:

The Fifth Wall network is rich with opportunities for Zipline to explore potential partnerships among our retail-focused partners and portfolio companies. However, we believe retail to be just the beginning for Zipline as we envision the product appealing to many Built World industries. The opportunity for Zipline within real estate could lie with organizations whose HQ office must communicate daily with field operations workers, such as more traditional brokers with a geographic focus (e.g., CBRE, Cushman & Wakefield), leasing agents within multifamily and SFR (e.g., Equity Residential, Greystar), or construction site workers.

Amazon’s GameOn app, a platform for sharing mobile gaming clips, launches on iOS,

Mobile gaming hasn’t seen the same demand for streaming content in the past as desktop has, but Amazon sees a market there to extend Twitch’s dominance. After launching on Android back in November, the company’s mobile streaming centric app has just launched on Apple’s App Store.

The app lets users record short clips (anywhere from 30 seconds to 5 minutes of content) of gameplay from a variety of titles that support screen recording capture. Users can screen record these clips directly into the GameOn library at which point they can add commentary or additional edits before publishing to the GameOn platform or sharing links to the platform on other sites.

The GameOn platform is interestingly fully disconnected from Twitch with separate branding and different channels. Amazon has been partnering with streamers to wholly focus on mobile gaming while promoting challenges unique to the app.

Developers have been increasingly vigilant about brining more full-featured ports of desktop titles to mobile though the lack of sophisticated controls has made this a challenge. As gaming platforms aim to bring cloud streaming networks to iOS there could end up being more demand for shot-on-mobile content and titles that users control with a gamepad, but this will depend on whether the App Store grows more amenable to these platforms over time.

West Tenth’s app encourages women to start home businesses, not join MLMs

A new digital marketplace called West Tenth, now backed by $1.5 million in seed funding, wants to give women a platform to start and grow their home-based businesses. Through its mobile app, women can promote their business to others in the local community, then field inquiries and requests through the app’s integrated messaging platform, as well as finalize transactions through in-app payments.

The startup was co-founded by Lyn Johnson and Sara Sparhawk, who met when they both worked in finance. Johnson remained in finance, but Sparhawk later moved on to work at Amazon.

Johnson explains that her experience led her to better understand the economic inequality of women in the U.S., where they only own 32 cents to every dollar in financial assets than men own. A large driver of this is that women leave the workforce, often to raise children, which results in years where they don’t have earnings.

“We’re really good as a society at supporting women on the way of out of the workforce to care for their kids, but really terrible at supporting them on the way back in,” Johnson says. “Women know this, and as an alternative to employment that just seems to fail them, they’re starting businesses in droves.”

With West Tenth, the goal is to encourage this sort of entrepreneurship — and more broadly, to help women understand that the many of the talents they’ve developed at home are, in fact, potential businesses.

This includes opportunities like home-based bakers and cooks, photographers, home organizers or designers, home florists, baby sleep consultants, party planning and event services, crafting classes, fitness training, homemade goods, and more.

The company notes that the app isn’t necessarily closed to men, but the current market for U.S. home businesses favors women as they’re more often the partner who chooses to leave work to raise children. However, there are some men on its platform.

Though today many of these entrepreneurs market their home businesses on Facebook, they’re missing opportunities to reach customers if they’re not heavily involved in local groups and responding to requests for recommendations. West Tenth instead centralizes local businesses in one place to make discovery easier.

In the app, customers can browse and shop local businesses, filtering by category via buttons at the top of the screen. The results are sorted by distance and offer photos, description, and the starting price for the goods or services offered. Through integrated messaging, users can reach out directly for a quote or more information. Customers can also complete their purchases through the app’s Stripe payments integration. West Tenth takes a 9.5% commission on these sales.

Another key aspect to West Tenth is its education component, The Foundry.

Through a $100 per quarter subscription membership (or $350 per year), business owners will be able to attend bi-monthly events, including classes focused on the fundamentals of setting up home-based businesses, marketing, customer acquisition, and other topics. These classes will also be available à la carte at around $30 apiece, for those who want to pay per session.

In addition, attendees will hear from guest speakers who have experience in the home-based business market, and they’ll be able join mastermind networking groups to exchange ideas with their peers.

Image Credits: West Tenth

This system of combining education and networking with business ownership could potentially help more women become home-based business entrepreneurs instead of joining multi-level marketing (MLM) companies, as is common.

“When we started this, we recognized that MLMs are one of the few kind of industries that’s focused on this demographic of women who’ve left the workforce — which is a huge, untapped talent pool in the U.S.,” notes Johnson. “But they’re really predatory. Only the top 1% of sellers distributors really make money and the rest lose money. And they lose their social capital, as well. What we’re really interested in doing is becoming an alternative to MLMs in many respects,” she adds.

Not surprisingly, MLMs aren’t allowed on the West Tenth platform.

The startup, which completed Kansas City TechStars last summer, has now raised $1.5 million in seed funding to get its platform off the ground. The round was led by Better Ventures along with Stand Together Ventures Lab, Kapital Partners,The Community Fund, Backstage Capital, Wedbush Ventures, and Gaingels.

The funds will be used to develop the product and grow its user base. In time, West Tenth aims to build out product features to better highlight local businesses. This includes shopping elements that will let you see what friends are buying and video demonstrations, among other things.

Since 2019, West Tenth has grown its footprint from just 20 businesses on the app to now over 600, largely in suburban L.A. and Salt Lake City. It’s now aiming to target growth in Phoenix, Boise, and Northern California.

Image Credits: West Tenth

The timing for West Tenth’s expansion is coming on the tail end of the COVID-19 crisis, where things have only gotten worse for women’s traditional employment.

School and daycare closures combined with job losses that greatly impacted women’s roles have now driven more women out of the workforce compared with men. And according to McKinsey, women accounted for nearly 56% of workforce exits since the start of the pandemic, despite making up just 48% of the workforce. This COVID-driven “shecession,” as some have dubbed it, is also disproportionately impacting women of color, studies have found.

“We’ve seen 5 million women exit the workforce — some because they were laid off or furloughed, and a huge chunk because they’re opting out because the caregiving responsibilities just became overwhelming,” says Johnson.

“The thing is when women leave the workforce for caregiving reasons — for some reason we really discount that and we make it even harder for them to return to work. So I think over the next 18 to 24 months, we’ll see a big surge in economic activity in the home with women trying to bring in additional sources of income by running a business from the home,” she says.

The West Tenth app is available on both iOS and Android.

Amazon issues rare apology in India over drama series

Amazon on Tuesday issued a rare apology to users in India for an original political drama series over allegations that a few scenes in the nine-part mini series hurt religious sentiments of some people in the key overseas market.

The series, called “Tandav,” has faced criticism from some people in India — including a few members of the ruling Bhartiya Janata Party — over its depiction of Hindu gods and goddesses.

In a message titled, “Amazon Prime Video Apologizes,” the American e-commerce group said it “deeply regrets that viewers considered certain scenes to be objectionable” and that it had either edited those scenes or removed them altogether from the show after hearing concerns from viewers.

“We respect our viewers’ diverse beliefs and apologize unconditionally to anyone who felt hurt by these scenes. Our teams follow company content evaluation processes, which we acknowledge need to be constantly updated to better serve our audiences. We will continue to develop entertaining content with partners, while complying with the laws of India and respecting the diversity of culture and beliefs of our audiences.”

The show, which stars several top Bollywood actors including Saif Ali Khan, premiered in mid-January and immediately prompted controversy and criminal complaints. Things have escalated in recent weeks as several high-profile executives of Amazon Prime Video have been questioned by the authority.

Prime Video has amassed millions of subscribers in India, where it competes with Disney’s Hotstar, Netflix, Times Internet’s MX Player, and dozens more streaming services. Amazon has grown more aggressive with Prime Video in India in recent months. It recently introduced an even cheaper subscription tier and secured rights for streaming some cricket matches.

Amazon’s rare apology today comes days after New Delhi announced new rules for on-demand video streaming services and social media firms.

Until now Amazon Prime Video and other streaming services have operated in India without having to worry too much about the nature of their content. But that’s changing, according to the new rules.

“The category classification of a content will take into account the potentially offensive impact of a film on matters such as caste, race, gender, religion, disability or sexuality that may arise in a wide range of works, and the classification decision will take account of the strength or impact of their inclusion,” the new rules state.

As we wrote recently, the controversy surrounding the political drama and the new rules from India for streaming services are only few of the challenges that Amazon is facing in India, where it has committed to deploy over $6.5 billion.

Last month, an influential India trader group that represents tens of millions of brick-and-mortar retailers called New Delhi to ban Amazon in the country after an investigation by Reuters claimed that the American e-commerce group had given preferential treatment to a small group of sellers in India, publicly misrepresented its ties with those sellers and used them to circumvent foreign investment rules in the country.

SkyMul’s drones secure rebar on the fly to speed up construction

There are many jobs in the construction industry that fall under the “dull, dirty, and dangerous” category said to be ripe for automation — but only a few can actually be taken on with today’s technology. One such job is the crucial but repetitive task of rebar tying, which a startup called SkyMul is aiming to completely automate using fleets of drones.

Unless you’ve put together reinforced concrete at some point in your life, you may not know what rebar tying is. The steel rebar that provides strength to concrete floors, walls, and other structures is held in place during the pouring process by tying it to the other rebar where the rods cross. For a good-size building or bridge this can easily be thousands of ties — and the process is generally done manually.

Rodbusters (as rebar tying specialists are called, or so I’m told) are masters of the art of looping a short length of plastic or wire around an intersection between two pieces of rebar, then twisting and tying it tightly so that the rods are secured in multiple directions. It must be done precisely and efficiently, and so it is — but it’s backbreaking, repetitive work. Though any professional must feel pride in what they do, I doubt anyone cherishes the chronic pain they get from doing that task thousands of times in an hour. As you might expect, rodbusters have high injury rates and develop chronic issues.

Automation of rebar tying is tricky because it happens in so many different circumstances. A prominent semi-robotic solution is the TyBot, which is a sort of rail-mounted gantry that suspends itself over the surface — but while this makes sense for a bridge, it makes far less for the 20th floor of an office building.

Enter SkyMul, a startup still in the very early stages but with a compelling pitch: rebar tying done by a fleet of drones. When you consider that the tying process doesn’t involve too much force, and that computer vision has gotten more than good enough to locate the spots that need work… it starts sounding kind of obvious.

CEO and co-founder Eohan George said that they evaluated a number of different robotic solutions but that drones are the only ones that make sense. The only legged robots with the dexterity to pick their way through the rebar are too expensive, and treads and wheels are too likely to move the unsecured rebar.

Diagram showing how SkyMul's drones map an area of rebar then divide it up for tying.

Here’s how the company’s SkyTy system works. First, a mapper drone flies over the site to mark the boundaries and then, in an automated closer flyover, to build a map of the rebar itself and where the ties will need to go. This map is then double-checked by the rodbuster technician running the show, which George said only takes about a minute per thousand square feet of rebar (though that adds up quickly).

Then the tying drones are released, as many as needed or wanted. Each one moves from spot to spot, hovering and descending until its tying tool (much like those used by human rodbusters) spans the rebar intersection; the tie is wrapped, twisted, and the drone is off to the next spot. They need their batteries swapped every 25 minutes, which means they generally have time to put down 70-80 ties; right now each drone does one tie every 20 seconds, which is in line with humans, who can do it faster but generally go at about that speed or slower, according to numbers George cited.

It’s difficult to estimate the cost savings and value of the work SkyTy does, because the value of the labor varies widely. In some places rodbusters are earning north of $80/hour, meaning the draw of automation is in cost savings. But in other markets the pay is less than a third of that, which compounded with the injury risk makes rodbusters a scarce quantity — so the value is in availability and reliability. Drone-based tying seems to offer value one way or the other, but that means the business model is somewhat in flux as SkyMul figures out what makes the most sense. Generally contractors at one level or another would lease and eventually own their own drones, though other methods are being looked into.

The system offers value-add services as well, for instance the precise map of the rebar generated at the beginning, which can be archived and used later for maintenance, quality assurance, comparison with plans, and other purposes. Once a contractor is convinced it’s as good or better than the manually-produced ones currently used, this could save hours, turning a 3-day job into a 2-day job or otherwise simplifying logistics.

The plan at the company is to first offer SkyTy as an option for bridge construction, which is a simpler environment than a multi-story building for the drones. The market there is on the order of $30-40 million per year for rebar tying services, providing an easier path to the more complex deployments.

SkyMul is looking for funding, having spun out of Georgia Tech and going through Comcast-NBC accelerator The Farm and then being granted a National Science Foundation SBIR Phase I award (with hopes for a Phase II). They have demonstrated the system but have yet to enter into any pilot programs — there are partnerships in the works but the construction business isn’t a nimble one and a drone-based solution isn’t trivial to swap in for human rodbusters on short notice. But once a few projects are under its belt the company seems likely to find serious traction among forward-thinking contractors.
