Houston company creates portable device that eases pain without the use of drugs

No pain, just gain

Many of the estimated 50 million Americans who suffer from chronic pain turn to drugs — including heavily abused opioids — to relieve their symptoms. Houston-based startup Portable Therapeutix LLC's drug-free solution to pain management seeks to put a dent in the market for prescription painkillers.

In 2018, Houston-based Portable Therapeutix introduced Squid Go, a portable device that's designed to ease the pain and swelling of sore joints and muscles. It's a follow-up to the company's Squid Compression, a pain management device launched in 2013 for patients at rehabilitation centers, hospitals, doctor's offices, and the like.

Squid Go enables consumers to apply two approaches — cold therapy and compression therapy — to relieving joint pain and swelling caused by arthritis, bouncing back from athletic activities, or recovering from an injury or surgery involving muscles and joints. Variations of the device can treat ankle, back, leg, knee, shoulder, or wrist pain.

To reap the benefits of Squid Go, a consumer uses the device for just 15 minutes. Squid Go — which combines a cold gel pack with proprietary compression technology — features special air pockets that inflate and deflate, gently massaging the body part needing treatment. That massaging boosts circulation and reduces swelling.

"Increased circulation brings more nutrient- and oxygen-rich blood to the area, promoting recovery," says Sam Stolbun, co-founder of Portable Therapeutix. "Meanwhile, [the] gentle compression also drives the pain-relieving cold from the gel pack deeper into the tissues to alleviate soreness and discomfort."

The coldness of the gel pack fights inflammation.

Stolbun says someone can take the lightweight, portable Squid Go device to the office, to the gym or anywhere else for on-the-go pain relief. It even can be used without the cold gel pack for compression-only therapy to improve circulation and decrease swelling. The Squid Go pump delivers about 15 treatments before it needs to be recharged.

Squid Compression received clearance from the U.S. Food and Drug Administration as a prescription-only device in 2013 and gained over-the-counter status in 2014. The consumer version, Squid Go, employs the same technology and operates the same way as Squid Compression, so a second FDA stamp of approval wasn't required.

Pricing for the heavy-duty Squid Compression system starts at $700. The consumer-friendly Squid Go system goes for $300 or $350, depending on its purpose. Users can buy extra wraps and gel packs to supplement the system.

Stolbun says he and co-founder Shai Schubert developed the Squid devices after realizing that existing pain-fighting cold packs provided only superficial relief, while water-based treatments were inconvenient and offered no compression advantages. Still other cold and compression therapies on the market are expensive and generally aren't covered by health insurance, he says.

Stolbun says that "it became apparent that a reasonably priced, well-made, portable, and effective pain relief and recovery device would meet a need for a broad range of consumers — from athletes to seniors."

Stolbun, a sports enthusiast and bakery mogul, and Schubert, a scientist and entrepreneur, established Portable Therapeutix in 2011.

The company's debut product, Squid Compression, still enjoys success, but Stolbun says the company has shifted its focus to Squid Go. Portable Therapeutix plans to pump up sales for Squid Go via its online presence, he says, as well as through physical therapists, sports trainers and other professionals who've used Squid Compression but want to offer the less pricey Squid Go model to their clients for in-home treatment.

Portable Therapeutix is backed by private investors; the amount of funding it has received isn't available. The company doesn't release revenue and profit figures.

Today, the company employs just one person in Houston but will add workers as its distribution pipeline expands, Stolbun says. Sales, marketing, and customer service representatives are scattered around the country. Stolbun, the CEO, is based in Houston, while Schubert, the chief technical officer, is based in Boston.

Portable Therapeutix relies, in part, on word-of-mouth praise to promote Squid Go. Among those hailing the device is Lee Ward of Houston, who describes himself as a competitive tennis player.

On the Squid Go website, Ward explains that he'd been suffering from progressively worsening tendonitis in his knees for a couple of years.

"I tried a number of remedies, including ice and gel packs, immediately following my tennis workout, but both remedies were ineffective and difficult to use," Ward says in his online testimonial.

He then discovered Squid Go and became a fan.

"The best thing about [Squid Go] is its ease of use. It provides a quick, effective treatment that makes it ideal for daily use by both the serious and recreational athlete," Ward says.

Houston Innovation Awards to honor Wade Pinder as 2025 Trailblazer

And the award goes to...

On Nov. 13, we'll gather for the 2025 Houston Innovation Awards to celebrate the best and brightest in Houston innovation right now. And, as is tradition with the annual program, we'll honor one longstanding Houston innovator with the Trailblazer Award.

The award was established to recognize an individual who has left a profound impact on Houston's business and innovation ecosystem and is dedicated to continuing to support Houston and its entrepreneurs. The recipient is selected by our esteemed panel of judges from a pool of internal and external recommendations.

The 2025 Trailblazer Award recipient is Wade Pinder of Product Houston. A familiar face to those active in Houston's innovation sector, Pinder identifies as an "Ecosystem Wayseeker" and is the founder of Product Houston.

Pinder, a former product manager at Blinds.com, arrived in Houston in 2008 and has been deeply engaged in Houston’s startup and innovation scene since 2012. Over the years, he has supported hundreds of founders, product leaders, and community builders across the Houston area.

In 2023, he was honored as Mentor of the Year in the Houston Innovation Awards. Today, he fosters collaboration, clarity, and connection through his work at Product Houston, and he helps innovators find their place in the local sector via his monthly "Houston Ecosystem Mapping" sessions.

Read below for Pinder's insightful takes on the Houston innovation scene and what it means to blaze a new trail. Then, join us as we celebrate Pinder and all of our nominees and winners at the 2025 Houston Innovation Awards on Nov. 13 at Greentown Labs. Tickets are available now.

InnovationMap: Describe the growth of the Houston innovation ecosystem from your arrival in 2008 to now.

Wade Pinder: When I first arrived in Houston in 2008, the innovation ecosystem was more fragmented than it is today. Connecting with other innovators often meant attending a lot of hit-or-miss events. Over the years, it’s been incredible to see the network take shape and grow into a true community. I’ve had the privilege of being involved with several coworking spaces and accelerator programs along the way, and it’s been especially exciting to see Station Houston evolve into what is now the Ion District. What makes the Ion unique is how it blends openness and opportunity… ideas spill into and out of the space, and anyone can walk in, participate in programming, and find themselves in proximity to people who might help them take the next steps.

Additionally, the expansion of spaces like Texas Medical Center Innovation, Helix Park, The Cannon, and many others, have broadened Houston’s innovation landscape in powerful ways.

Today, when someone new moves to Houston and wants to plug into the startup and innovation scene, it’s much easier for them to find their way than when I moved here in 2008. I think that’s something Houston can really be proud of.

IM: As someone who engages with the broader Houston innovation community on a regular basis, what are the shared characteristics and traits that you see among its members?

WP: One of the things that makes Houston’s innovation community unique is how deeply it’s rooted in industry. So many of the innovators I meet come from within Houston’s major sectors, and they’ve seen firsthand where opportunities lie, which gives their innovation a certain practicality. They’re developing solutions that solve real, often complex, business and industry problems, not chasing trends or trying to create the next flashy consumer app.

What I admire most is that this community is growing in its understanding of the value of collaboration. They work with the systems and expertise that already exist, and find better ways to make them work together. Another shared trait I see across Houston’s innovators is a deep sense of curiosity and a drive to question the status quo while looking for better ways to build, improve, and solve.

IM: You’ve said, "Houston has Houston problems, and Houston needs Houston solutions." How do you see this taking shape in the innovation sector right now?

WP: When I first started getting connected to Houston’s startup and innovation scene in 2012, I noticed folks had a tendency to look at other cities and ask, "How can we do what they did?" Back then, we saw phrases like "Silicon Bayou" pop up, and while that enthusiasm was hopeful, it often discounted the things that make Houston unique. Over time, I’ve come to believe that the better question is: "What are we already great at, and how can we innovate from there?" The flip side of that question is to reflect on the things that hold us back as an ecosystem… identifying the friction points and finding practical ways to smooth them out.

From my time wandering around our ecosystem, I’ve come to understand Houston is great at infrastructure at scale, solving life-and-death challenges in the global spotlight, and "boldly going where no one’s gone before." These three things, in my opinion, capture the essence of Houston does best: We do hard things here.

What excites me today is that we’re applying innovation to those core strengths in ways that feel authentically Houston. One area I’m especially excited about is the emergence of the “New Space Economy,” captured beautifully in Wogbe Ofori’s thought piece “The Astropreneur’s Startup Journey Map.” It's a great example of how the next wave of space-related innovation might connect to Houston’s long-standing strengths in manufacturing, logistics, and problem-solving at scale.

Another challenge Houston faces is what I call a "proximity problem." Even when events are only a few miles apart, traffic can make it difficult for people to stay connected across the city. That’s why I’m so encouraged by the rise of what I think of as "intent-based gatherings" around the city: events designed with purpose, where people know they’ll find real connection and value once they arrive.

IM: Finally, what does being a "Trailblazer" mean to you?
WP: To me, trailblazing in the Houston innovation ecosystem means being willing to wander through the many different corners of the community and look for value in places we often overlook. It’s about showing up at events, community meetings, and pitch competitions — not just to participate, but to notice how each of these "nodes" in the ecosystem connects and adds value to the others.

Sometimes the trailblazer only walks a trail once: as they are discovering it. If you can help others see a newfound trail’s purpose and potential, it becomes a path others can follow more easily in the future. That’s the real work of a trailblazer: mapping connections, framing their value, and helping people recognize how those pathways strengthen the ecosystem as a whole.

In a broader sense, trailblazing is about seeing things not just as they are, but as they could be. Then taking the steps, however small, that make that vision real.

Houston-area VC funding sunk to 5-year low in Q3 2025, report says

by the numbers

Fundraising for Houston-area startups experienced a summertime slowdown, sinking to a five-year low in the third quarter, according to the latest PitchBook-NVCA Venture Monitor.

The PitchBook-NVCA Venture Monitor shows startups in the Houston metro area attracted $204.4 million in venture capital from June through August. That’s 55 percent below the total for the previous quarter and 51 percent below the total for the third quarter of 2024.

More telling than those figures is that the third-quarter haul dropped to its lowest total for Houston-area startups since the fourth quarter of 2020, when $133.4 million in VC was raised. That was the third full quarter after health officials declared the pandemic in the U.S.

In Q3 2025, AI accounted for nearly 40 percent of VC deal volume in the U.S., Kyle Stanford, director of U.S. venture research at PitchBook, said in the report. And through the first nine months of 2025, AI represented 64 percent of U.S. deal value.

VC deal activity “has been nearly steady, emphasizing a consistent influx of companies, especially at the pre-seed and seed stages,” Stanford said. “Large deals remain the primary driver of market deal value, with almost all of these deals focused on AI.”

Bobby Franklin, president and CEO of NVCA, said that while fundraising hasn’t returned to pre-pandemic highs, deal values are going up in sectors such as AI, manufacturing, robotics and space tech, many of which have already exceeded their investment totals for all of 2024.

Coya Therapeutics

Clinical-stage biotechnology company Coya Therapeutics (NASDAQ: COYA) has developed COYA-302 that enhances anti-inflammatory T cell function and suppresses harmful immune activity. The drug candidate is being advanced for several neurodegenerative diseases—including ALS, Alzheimer’s, Parkinson’s, and frontotemporal dementia—and has demonstrated promising reductions in neuroinflammation in preclinical and early clinical studies, according to the company.

Coya, founded in 2021, received FDA acceptance for its investigational new drug application for COYA-30 this summer. It closed its IPO in January 2023 for more than $15 million and added $26 million in PIPE funding that same year. Last year, the company secured an additional $15 million in PIPE funding.

Fervo Energy

Houston-based Fervo Energy is working to provide 24/7 carbon-free energy through the development of cost-competitive geothermal power. The company is developing its flagship Cape Station geothermal power project in Utah, which is expected to generate 400 megawatts of clean energy for the grid. The first phase of the project will supply 100 megawatts of power beginning in 2026. The second phase is scheduled to come online by 2028.

The company raised $205.6 million in capital to help finance the project earlier this year and fully contracted the project's capacity with the addition of a major power purchase agreement from Shell. Founded in 2017 by CEO Tim Latimer and CTO Jack Norbeck, Fervo is now a unicorn, meaning its valuation as a private company has surpassed $1 billion. In March, Axios reported Fervo is targeting a $2 billion to $4 billion valuation in an IPO.

Koda Health

Houston-based Koda Health has developed an advance care planning platform (ACP) that allows users to document and share their care preferences, goals and advance directives for health systems. The web-based platform guides patients through values-based decisions with interactive tools and generates state-specific, legally compliant documents that integrate seamlessly with electronic health record systems. The company also added kidney action planning to its suite of services for patients with serious illnesses last year.

Koda Health was founded out of the TMC's Biodesign Fellowship in 2020 by CEO Tatiana Fofanova, chief medical officer Dr. Desh Mohan, and chief technology officer Katelin Cherry. The company raised a $7 million series A earlier this year, and also announced major partnerships and integrations with Epic, Guidehealth, Medical Home Network, Privia Health and others.

Mati Carbon

Houston climatetech company Mati Carbon removes carbon through its Enhanced Rock Weathering (ERW) program that works with agricultural farms in Africa and India. Mati says the farmers it partners with are some of the most vulnerable to the impacts of climate change. The nonprofit won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation, earlier this year.

Mati Carbon scaled operations in India, Zambia, and Tanzania this year and has advanced its proprietary measurement, reporting and verification (MRV) platform, known as matiC, enabling seamless field data capture, chain-of-custody and carbon accounting at scale. The company was founded in 2022 by co-directors Shantanu Agarwal and Rwitwika Bhattacharya.

Molecule

Houston-based Molecule Software has developed an energy trading risk management (ETRM) platform that allows companies trading power, oil and gas, biofuels, renewables and more stay ahead as the markets evolve.

The company closed a Series B round earlier this year for an undisclosed amount. Sameer Soleja, founder and CEO of Molecule, said at the time that the funding would allow the company to "double down on product innovation, grow our team, and reach even more markets." The company was founded in 2012 by CEO Sameer Soleja and participated in the Surge Accelerator the same year.

Utility Global

Houston-based Utility Global has developed its proprietary eXERO technology that produces low-cost, clean hydrogen from water and industrial off-gases without requiring grid electricity.

First founded in 2018 by CEO Parker Meeks, the company participated in Greentown Labs and the Rice Alliance for Technology and Entrepreneurship programs. It raised a $55 million funding round earlier this year and launched commercial partnerships with ArcelorMittal Brazil and Hanwha Group in South Korea to deploy its hydrogen solutions at scale.
