A Houston-based medical device company born out of the Texas Medical Center has closed its series A round of funding.

Ictero Medical's oversubscribed $6 million round was led by MedTex Ventures, S3 Ventures, and an undisclosed strategic investor, according to a news release. The company's novel cryoablation system was designed to treat high-risk gallstone disease patients and provide a less invasive and lower risk alternative to gallbladder removal surgery — something over 1 million Americans undergo annually.

“Our technology provides an immediate solution for critically ill patients who currently have no good treatment options, and also has the potential to benefit healthier patients who want to avoid surgery,” says Ictero Co-Founder and CEO Matthew Nojoomi in the release.

Recently, Ictero Medical entered into a partnership with Houston medical device development firm Biotex. The collaboration provides the company with engineering resources and in-house manufacturing tools. Ictero also received capital support from MedTex Ventures through its Biotex Medical Device Fund.

“We are excited about working with the Ictero team to advance its technology, which we believe can significantly improve patient experiences and outcomes by providing a non-surgical alternative to treating gallbladder disease,” says Biotex CEO Ashok Gowda in the release.

The fresh funds will be put toward further product development and initial clinical testing.

“MedTex Ventures is enthusiastic about Ictero’s novel cryoablation technology and its potential to solve the unmet need of inoperable patients with gallbladder disease,” says John Fichthorn, CIO of MedTex Ventures, in the news release. “Equally important is the team. We believe the combination of Ictero and Biotex’s technical capabilities, alongside the support from key investors with commercial experience, such as S3 Ventures, position the company for long term success.”

Ictero was founded as a part of the Texas Medical Center’s Biodesign Fellowship program in 2018. Since launch, the company has received a Phase I NSF grant and closed a $1 million seed round co-led by the Texas Medical Center Venture Fund and Texas HALO Fund.

“Ictero is at the forefront of pioneering cryotherapy for gallstone disease, and S3 Ventures is excited about the potential for Ictero’s novel solution to rapidly bring an impactful outcome to patients,” says Kim Rodriguez, venture partner at S3, in the release. “Our research suggests a substantial opportunity to help patients suffering from gallstone disease who are dependent on drainage catheters or too sick for surgery. We are joining a solid investment syndicate in supporting a very capable team.”

Billed as the "largest venture capital fund focused on the state of Texas," S3 Ventures's recently announced $250 million Fund VII is focused on investing in Texas startups.

S3 Ventures usually invests $500,000 to $10 million in seed, series A or series B rounds with the capacity to invest more than $20 million throughout the life of a company. The firm has made more than 50 investments since it was founded in 2005 and has more than 25 active portfolio companies and over 20 exits.

“In our first 17 years, we have been fortunate to partner with truly visionary founders who have transformed the way we work, live and heal,” says S3 Managing Director Brian R. Smith in a news release. “We look forward to working with many more in the years ahead.”

The firm has Houston startups in its portfolio: BrainCheck, a provider of interactive cognitive assessment and care planning technology; Saranas, an early bleed detection system; and BuildForce, a construction labor marketplace.

“We believe that by 2030, Texas could be the second-largest technology ecosystem in the country,” Smith said. “That growth is being driven by long-term demographic shifts and broad-based economic strength of not just Austin, but also Dallas, Houston and San Antonio.”

Houston-based early bleed detection medical device company Saranas has been granted a new patent from the Department of Commerce’s United States Patent and Trademark Office. The patent, titled “Access Closure with Bleed Monitoring,” allows for embedding a vascular access closure device with the company’s proprietary bleed monitoring technology.

“As we continue to grow our commercial presence with the Early Bird, we are pleased to secure this important patent that is designed to further expand the implementation of our differentiated bleed monitoring technology,” says Saranas CEO James Reinstein in a news release. “This patent award demonstrates Saranas’ commitment to innovation and further strengthens our intellectual property portfolio.”

At the end of 2021, Saranas announced its first patient in its clinical trials at Morristown Medical Center in Morristown, New Jersey. The trial will eventually enroll up to 265 patients across the U.S.

"We have been using the Early Bird in our clinical practice for the past two years, and the current design of incorporating a fully functional introducer sheath with bleed detection allows for seamless integration into high risk interventional cardiovascular procedures," Dr. Philippe Généreux, interventional cardiologist, says. "Embedding bleed detection directly onto a vascular closure device is the eventual next step and has the potential to become the standard of care across all types of vascular access procedures.”

Houston health tech startup closes $10M series B led by Austin investors

money moves

A Houston-based tech company that's tackling cognitive health diagnoses with its innovative platform has closed its latest round of funding.

BrainCheck, the cognitive health care platform for physicians, announced the closing of its $10 million series B funding led by Austin-based investors, Next Coast Ventures and S3 Ventures. The funding will be used to expand research and development, including developing a digital therapeutic and enhancing go-to-market capabilities.

BrainCheck's digital platform allows physicians to better assess cognitive function in their patients — whether they are elderly dementia patients or suffering from other cognitive ailments. One in nine adults aged 45 and older report subjective cognitive decline, according to a news release, and one in 14 COVID-19 survivors have neurocognitive disorder.

"We are at the forefront of improving access to cognitive assessment and care," says Yael Katz, co-founder and CEO of BrainCheck, in the release. "With early diagnosis comes treatment and intervention. These funds will allow us to accelerate the adoption of our platform and work with clinicians to help more patients live better and safer lives, decrease caregiver frustration, and save health systems trillions of dollars. I believe that BrainCheck can help cognitive care evolve the way cancer care has since the 1970s, when chemotherapy was one-size-fits-all."

Katz co-founded the company with neuroscientist David Eagleman in January of 2015. Now, doctors at over 400 neurology, primary care and geriatrics practices — such as Cleveland Clinic, MD Anderson, and Johns Hopkins — are already using BrainCheck's 10-to-15-minute test, which is covered by Medicare and by most private insurers, to conduct cognitive testing. The FDA Class II Software as a Medical Device (SaMD), which means that physicians can facilitate in-person or even an remote assessment of their patients' cognitive function.

"BrainCheck is a breakthrough platform that has the potential to transform how we diagnose and treat cognitive impairment," says Michael Smerklo, co-founder and managing director of Next Coast Ventures, in the release. "The combination of technical sophistication and ease of use makes BrainCheck a perfect tool for doctors and health systems everywhere. I'm so impressed by what Dr. Katz and her team have achieved to date and am excited to support the team as they continue to innovate and scale."

Other investors included Nueterra Capital, Tensility Ventures, and True Wealth Ventures, as well as UPMC Enterprises and SelectQuote, which joined on as strategic investors.

"BrainCheck shows promise as a cognitive assessment tool that would allow patients to independently complete the test while allowing physicians to spend more time reviewing the results and planning care with patients," says Dr. Adele Towers, director of risk adjustment at UPMC Enterprises and a geriatric medicine specialist at UPMC, in the release.

BrainCheck closed its $8 million series A round in October of 2019, and the company moved into its new office in Upper Kirby following the raise in early 2020. The startup also has an office in Austin.

Houston construction tech company raises $4M round

money moves

A locally founded company that's focusing on changing the construction labor game has raised a round of institutional funding.

Buildforce, which splits its headquarters between Houston and Austin, closed its latest round of funding at $4 million. The round was led by Maryland-based TDF Ventures, with participation from existing investor Houston-based Mercury Fund and Austin-based S3 Ventures.

The company uses construction staffing and management software to more efficiently connect contractors to skilled workers across trades — electrical, mechanical, plumbing, flooring, concrete, painting, and more.

"Contractors depend on skilled and reliable tradespeople to meet project timelines," says Moody Heard, co-founder and CEO of Buildforce, in a news release. "Our key insight is that by optimizing the user experience for skilled tradespeople seeking higher pay and job security, we are able to help meet contractors' needs. We're thrilled to have become the partner of choice for the top contractors in our current markets looking to connect with this workforce."

The new funds will support the startup as it scales, grows revenue, develops its product, and more.

"The US has millions of unfilled openings for skilled tradespeople, yet consistent work remains out-of-reach for many construction professionals," says Will Rayner, principal at TDF Ventures, in the release. "Buildforce's exponential growth in 2021 is a testament to the company's ability to connect supply and demand in this difficult labor market at scale."

The company closed an earlier round of funding in April. That round was led by Mercury.

Houston-based medical device company snags $12.8M in series B

following the money

A Houston company that's changing the game when it comes to early bleed detection has raised its next round of funding.

Saranas Inc. announced that it closed a $12.8 million series B investment led by Wisconsin-based Baird Capital, the venture capital and global private equity arm of Baird, a global company with a location in Houston. Austin-based S3 Ventures also supported the round.

The company will use the funds to continue its clinical trials, per a news release.

"We are pleased to announce this round of funding led by Baird Capital," says Saranas President and CEO James Reinstein in the release. "It underscores the importance of real-time monitoring of bleeding complications and our opportunity to accelerate the commercialization of Early Bird. We look forward to expanding our clinical evidence through prospective clinical trials and launching next generation products, including Bird on a Wire, to address a much broader range of endovascular procedures."

Saranas received FDA approval for its Early Bird Bleed Monitoring System in 2019, as well as began its clinical trials. The device is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels. Around 20 percent of patients suffer a bleeding complication during endovascular procedures, like transcatheter aortic valve replacement, endovascular aneurysm repair, and percutaneous hemodynamic support. According to the release, the Early Bird remains the first and only device of its kind.

"As the Saranas team will say, 'Bleeding happens, but complications don't have to,'" says Amy Len Kobe, principal with Baird Capital, in the release. "Baird Capital is proud to partner with Saranas to address bleeding complication challenges and provide solutions that improve outcomes and reduce costs for patients, physicians and providers. We are also pleased to invest in Houston, a growing ecosystem of healthcare innovation and a target market for Baird."

Baird has operated an office locally since 1985, and the venture group has a partnership with the Texas Medical Center since 2018.

S3 Ventures also has an established presence in Houston, and health care technology is one of the three verticals the fund focuses on.

"S3 is enthusiastic about Saranas' game-changing medical device advancements," says Brian R. Smith, managing director of S3 Ventures, in the release. "We invest in companies that are re-imagining the way the world works, lives and heals, and we believe Saranas is a perfect representation of this."

Innovative Houston-area hardtech startup closes $5M seed round

fresh funding

Conroe-based hardtech startup FluxWorks has closed a $5 million seed round.

The funding was led by Austin-based Scout Ventures, which invests in early-stage startups working to solve national security challenges.

Michigan Capital Network also contributed to the round from its MCN Venture Fund V. The fund is one of 18 selected by the Department of Defense and Small Business Administration to participate in the Small Business Investment Company Critical Technologies Initiative, which will invest $4 billion into over 1,700 portfolio companies.

FluxWorks reports that it will use the funding to drive the commercialization of its flagship Celestial Gear technology.

"At Scout, we invest in 'frontier tech' that is essential to national interest. FluxWorks is doing exactly that by solving critical hardware bottlenecks with its flagship Celestial Gear technology ... This is about more than just gears; it’s about strengthening our industrial infrastructure," Scout Ventures shared in a LinkedIn post.

Investment bank opens new Houston office focused on energy sector

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.
