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.

He mentors through organizations like Capital Factory, TMC Biodesign, UT Venture Mentoring, UTMB Innovation and Rice's Global Medical Innovation program.

"Being a mentor means empowering early-stage innovators to shape, test, and refine their ideas with clarity and purpose," Shetty says. "I’m driven by the opportunity to help them think strategically and pivot early before resources are wasted. At this critical stage, most founders lack the financial means to bring on seasoned experts and often haven’t yet gained real-world exposure. Mentorship allows me to fill that gap, offering guidance that accelerates their learning curve and increases the chances of meaningful, sustainable impact."

Jason Ethier, EnergyTech Nexus

Jason Ethier is the founding partner of EnergyTech Nexus, through which he has mentored numerous startups and Innovation Awards finalists, including Geokiln, Energy AI Solutions, Capwell Services and Corrolytics. He founded Dynamo Micropower in 2011 and served as its president and CEO. He later co-founded Greentown Labs in Massachusetts and helped bring the accelerator to Houston.

"Being a mentor means using my experience to help founders see a clearer path to success. I’ve spent years navigating the ups and downs of building companies, struggling with cash flow, and making all the mistakes; mentoring gives me the chance to share those lessons and show entrepreneurs the shortcuts I wish I’d known earlier," Ethier says. "At Energytech Nexus, that role goes beyond just helping individual founders — it’s about creating a flywheel effect for Houston’s entire innovation ecosystem."

Jeremy Pitts, Activate Houston

Jeremy Pitts serves as managing director of Activate Houston, which launched in Houston last year. He was one of the founders of Greentown Labs in the Boston area and served in a leadership role for the organization between 2011 and 2015. Through Activate, he has mentored numerous impactful startups and Innovation Awards finalists, including Solidec, Coflux Purification, Bairitone Health, Newfound Materials, Deep Anchor Solutions and others.

"Being a mentor to me is very much about supporting the person in whatever they need. Oftentimes that means supporting the business—providing guidance and advice, feedback, introductions, etc," But just as important is recognizing the person and helping them with whatever challenges they are going through ... Sometimes they need a hype man to tell them how awesome they are and that they can go do whatever hard thing they need to do. Sometimes they just need an empathetic listener who can relate to how hard these things are. Being there for the person and supporting them on their journey is key to my mentorship style."

Joe Alapat, Liongard

Joe Alapat founded and serves as chief strategy officer at Houston software company Liongard and chief information officer at Empact IT, which he also owns. He mentors through Founder Fridays Houston Group, Software Day by Mercury Fund, SUPERGirls SHINE Foundation, Cup of Joey and at the Ion. He's worked with founders of FlowCare, STEAM OnDemand, Lokum and many other early stage startups.

"Being a mentor to me means unleashing an individual’s 10x—their purpose, their ikigai (a Japanese concept that speaks to a person’s reason for being)," Alapat says. "Mentoring founders in the Houston community of early stage, high-growth startups is an honor for me. I get to live vicariously through a founder’s vision of the future. Once they show me that compelling vision, I’m drawn to bring the future forward with them so the vision becomes reality with a sense of urgency."

Dikeman has helped launch several successful startups himself, most recently serving on the board of directors for Resilient Power Systems, which was acquired by Eaton Corp for $150 million.

"Founders have to find their own path, and most founders need a safe space where they can discuss hard truths outside of being 'on' in sales mode with their team or board or investors, to let them be able to work on their business, not just in it," Dikeman says.

Nisha Desai, Intention

Nisha Desai serves as CEO of investment firm Intention and mentors through Greentown Labs, TEX-E, Open Minds, the Rice Alliance Clean Energy Accelerator, Avatar Innovations and The Greenhouse. She currently works with founders from Solidec, Deep Anchor Solutions, CLS Wind and several other local startups, several of which have been nominated for Innovation Awards this year. She's served a board member for Greentown Labs since 2021.

"When I first started mentoring, I viewed my role as someone who was supposed to prevent the founder from making bad decisions. Now, I see my role as a mentor as enabling the founder to develop their own decision-making capability," Desai says. "Sometimes that means giving them the space to make decisions that might be good, that might be bad, but that they can be accountable for. At the end of the day, being a mentor is like being granted a place on the founder's leadership development journey, and it's a privilege I'm grateful for."

Rice, Houston Methodist developing soft 'sleep cap' for brain health research

Researchers and scientists at Rice University and Houston Methodist are developing a “sleep cap” that aims to protect the brain against dementia and other similar diseases by measuring and improving deep sleep.

The project is a collaboration between Rice University engineering professors Daniel Preston, Vanessa Sanchez and Behnaam Aazhang; and Houston Methodist neurologist Dr. Timea Hodics and Dr. Gavin Britz, director of the Houston Methodist Neurological Institute and chairman of the Department of Neurosurgery.

According to Rice, deep sleep is essential for clearing waste products from the brain and nightly “cleaning cycles” help remove toxic proteins. These toxic proteins, like amyloids, can accumulate during the day and are linked to Alzheimer’s disease and other neurological issues.

Aazhang, director of the Rice Neuroengineering Initiative, and his team are building a system that not only tracks the brain’s clearing process but can also stimulate it, improving natural mechanisms that protect against neurodegeneration.

Earlier proof-of-concept versions of the caps successfully demonstrated the promise of this approach; however, they were rigid and uncomfortable for sleep.

Preston and Sanchez will work to transform the design of the cap into a soft, lightweight, textile-based version to make sleep easier, while also allowing the caps to be customizable and tailored for each patient.

“One of the areas of expertise we have here at Rice is designing wearable devices from soft and flexible materials,” Preston, an assistant professor of mechanical engineering, said in a news release. “We’ve already shown this concept works in rigid device prototypes. Now we’re building a soft, breathable cap that people can comfortably wear while they sleep.”

Additionally, the research team is pursuing ways to adapt their technology to measure neuroinflammation and stimulate the brain’s natural plasticity. Neuroinflammation, or swelling in the brain, can be caused by injury, stroke, disease or lifestyle factors and is increasingly recognized as a driver of neurodegeneration, according to Rice.

“Our brain has an incredible ability to rewire itself,” Aazhang added in the release. “If we can harness that through technology, we can open new doors for treating not just dementia but also traumatic brain injury, stroke, Parkinson’s disease and more.”

The project represents Rice’s broader commitment to brain health research and its support for the Dementia Prevention Research Institute of Texas (DPRIT), which passed voter approval last week. The university also recently launched its Rice Brain Institute.

As part of the project, Houston Methodist will provide access to clinicians and patients for early trials, which include studies on patients who have suffered traumatic brain injury and stroke.

“We have entered an era in neuroscience that will result in transformational cures in diseases of the brain and spinal cord,” Britz said in the release. “DPRIT could make Texas the hub of these discoveries.”

Autonomous truck company with Houston routes goes public

on a roll

Kodiak Robotics, a provider of AI-powered autonomous vehicle technology, has gone public through a SPAC merger and has rebranded as Kodiak AI. The company operates trucking routes to and from Houston, which has served as a launchpad for the business.

Privately held Kodiak, founded in 2018, merged with a special purpose acquisition company — publicly held Ares Acquisition Corp. II — to form Kodiak AI, whose stock now trades on the Nasdaq market.

In September, Mountain View, California-based Kodiak and New York City-based Ares disclosed a $145 million PIPE (private investment in public equity) investment from institutional investors to support the business combo. Since announcing the SPAC deal, more than $220 million has been raised for the new Kodiak.

“We believe these additional investments underscore our investors’ confidence in the value proposition of Kodiak’s safe and commercially deployed autonomous technology,” Don Burnette, founder and CEO of Kodiak, said in a news release.

“We look forward to leading the advancement of the commercial trucking and public sector industries,” he added, “and delivering on the exciting value creation opportunities ahead to the benefit of customers and shareholders.”

Last December, Kodiak debuted a facility near George Bush Intercontinental/Houston Airport for loading and loading driverless trucks. Transportation and logistics company Ryder operates the “truckport” for Ryder.

The facility serves freight routes to and from Houston, Dallas and Oklahoma City. Kodiak’s trucks currently operate with or without drivers. Kodiak’s inaugural route launched in 2024 between Houston and Dallas.

One of the companies using Kodiak’s technology is Austin-based Atlas Energy Solutions, which owns and operates four driverless trucks equipped with Kodiak’s driver-as-a-service technology. The trucks pick up fracking sand from Atlas’ Dune Express, a 42-mile conveyor system that carries sand from Atlas’ mine to sites near customers’ oil wells in the Permian Basin.

Altogether, Atlas has ordered 100 trucks that will run on Kodiak’s autonomous technology in an effort to automate Atlas’ supply chain.
