Editor's note: Every week, I introduce you to a handful of Houston innovators to know recently making headlines with news of innovative technology, investment activity, and more. This week's batch includes a podcast with the founder of a new venture firm, a former astronaut and recent award recipient, and a health care innovator with fresh funding.

Houston has a lot of the right ingredients for commercialization and scaling up companies, so when Zach Ellis moved to town to stand up a venture capital firm that made investments in diverse founders, he decided to go about it in an innovative way.

South Loop Ventures, which Ellis launched two years ago, invests in pre-seed and seed-stage startups across health care, climatetech, aerospace, sports, and fintech. While the first handful of investments, which have already been made, are into Houston-based companies, Ellis explains on the Houston Innovators Podcast that the firm plans to invest in promising companies from across the country and bring them into Houston's ecosystem to grow and scale.

"Any investor wants to feel like they are looking at the best possible investment opportunities in which to deploy capital," Ellis says on the show. "So that's reason No. 1 to cast your net as widely as possible.

"At the same time, you want to give any investment that you make greatest chances of success," he continues. "The biggest factor of success outside of the team and the capital you give them, is the customers that they can call upon. In bringing targeted companies to Houston or connecting them with Houston, you introduce the opportunity for them to achieve rapid scale and work with world-class partners very efficiently."

Two astronauts recently received Presidential Medals of Freedom from President Joe Biden for their leadership in space.

Ellen Ochoa, the former center director and astronaut at the NASA's Johnson Space Center in Houston, and Jane Rigby, senior project scientist for NASA’s James Webb Space Telescope, were honored at the White House on May 3.

Ochoa spent 30 years with NASA, which included being the 11th director of JSC, deputy center director of JSC, and director of Flight Crew Operations. She served on the nine-day STS-56 mission aboard the space shuttle Discovery in 1993, and became the first Hispanic woman in space. She flew four more times to space with STS-66, STS-96, STS-110, and more.

“I’m so grateful for all my amazing NASA colleagues who shared my career journey with me,” Ochoa says in a NASA news release. Read more.

Houston startup secures $10M to expand into rural communities

ready to grow

A Houston company that is working on a value-based model for primary care has fresh funding to support its mission.

Hamilton Health Box announced the completion of a $10 million series A funding round led by 1588 Ventures with participation from Memorial Hermann Health System, Impact Ventures by Johnson & Johnson Foundation, Texas Medical Center Venture Fund, and the Sullivan Brothers.

The company, founded in 2019 by Dr. Toby R. Hamilton, will use the funding to fuel its expansion into rural areas to help assist those living in Health Professional Shortage Areas, or HPSAs.

The company has pioneered a proprietary “small footprint primary care delivery model,” which is considered suitable for rural markets, employer worksites, office buildings, schools, and university campuses. The cost-effective microclinics are “prefabricated facilities” that are designed for primary care services, and employ a hybrid in-person and telemedicine care approach.

Hamilton began his career as a physician before founding Emerus Holdings, which is a micro-hospital system in the Houston area that later moved to private equity.

The recently acquired funding will help expedite the high-touch care model to 98 million Americans in HPSAs, which was a goal for when the company was established during the Covid-19 pandemic. HHB has made partnerships with Federally Qualified Health Centers (FQHCs) to provide primary care services both at existing FQHC centers and through new sites in rural areas.

"Hamilton Health Box that was designed to deliver the lowest possible price of primary and preventative care," Hamilton said in a previous interview with Innovation Map. "We built that to be able to take that care to the jobsite and meet the customer where they are at."

Dr. Toby Hamilton has seen Houston establish itself as a leader in health innovation, and he's been a part of that journey too. He started his career as a physician before founding Emerus Holdings, a micro-hospital system in the Houston area which later exited to private equity. He also founded a nonprofit focused on connecting hospital innovation leaders called the Healthcare Innovators Professional Society and led the Texas Medical Center's Biodesign program for two years.

Over the years, he says he's seen the potential develop for Houston to hold a significant role in health care innovation across the world — it's just going to take all hands on deck.

"As a community, if we can get behind that vision and be the place that tests, develops, and creates opportunities, Houston has the potential to be unlike anything in the world," he says on the Houston Innovators Podcast. Click here to listen and read more.

One of Houston's coworking companies is moving on up. Sesh Coworking is moving into a new space that's 10 times as large as its original location — and it's an optimal location too, say Meredith Wheeler and Maggie Segrich, founders of Sesh Coworking.

"Being able to grow our community at our beautiful original location in Montrose through the pandemic is a testament to the grit and resilience of Houstonians. We are so honored and grateful to be a part of their journey,” says Segrich. “We are excited that our new location in Midtown, near the Innovation District, will provide more Houstonians with the workspace and support they need."

The two-story space is expected to open in two phases. Tenants will first move into the space's second floor in January while the first floor, the larger of the two floors, completes construction and is expected in March. Click here to read more.

The greatest gymnast of all time has a new title to her many gymnastics accomplishments. Simone Biles recently joined mental health startup Cerebral as chief impact officer, and the company is backed by SoftBank and has a valuation of $4.8 billion.

Biles has been vocal about her passion for mental health. Cerebral was an official sponsor of Biles’ Gold Over America Tour, which took place from September to November, and is an official sponsor of the 2022 Simone Biles International Invitational, a gymnastics competition that will be held January 27-30 at Houston’s George R. Brown Convention Center. The Spring-based World Champions Centre, Biles’ home gym, stages the invitational.

“Mental health is just as important as physical health, but for far too long the stigma of mental health has prevented too many people from seeking help,” Biles says in a Cerebral news release. “I have my own challenges with mental health, and therapy has been very empowering for me as I try to be the best person that I can be. I believe everyone should have access to mental health resources, and Cerebral gives me the ability to personalize my mental health care experience.” Click here to read more.

Houston startup taps strategic partner to produce novel 'biobased leather'

cleaner products

A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal of producing Shorai for prototype samples.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," founder Zimri Hinshaw previously told InnovationMap.

Justice Department sues to block Houston-based HPE's $14B buyout of Juniper

M&A News

The Justice Department sued to block Hewlett Packard Enterprise's $14 billion acquisition of rival Juniper Networks on Thursday, the first attempt to stop a merger by a new Trump administration that is expected to take a softer approach to mergers.

The Justice complaint alleges that Hewlett Packer Enterprise, under increased competitive pressure from the fast-rising Juniper, was forced to discount products and services and invest more in its own innovation, eventually leading the company to simply buy its rival.

The lawsuit said that the combination of businesses would eliminate competition, raise prices and reduce innovation.

HPE and Juniper issued a joint statement Thursday, saying the companies strongly oppose the DOJ's decision.

“We will vigorously defend against the Department of Justice’s overreaching interpretation of antitrust laws and will demonstrate how this transaction will provide customers with greater innovation and choice, positively change the dynamics in the networking market,” the companies said.

The combined company would create more competition, not less, the companies said.

The Justice Department's intervention — the first of the new administration and just 10 days after Donald Trump's inauguration — comes as somewhat of a surprise. Most predicted a second Trump administration to ease up on antitrust enforcement and be more receptive to mergers and deal-making after years of hypervigilance under former President Joe Biden’s watch.

Hewlett Packard Enterprise announced one year ago that it was buying Juniper Networks for $40 a share in a deal expected to double HPE’s networking business.

In its complaint, the government painted a picture of Hewlett Packard Enterprise as a company desperate to keep up with a smaller rival that was taking its business.

HPE salespeople were concerned about the “Juniper threat,” the complaint said, also alleging that one former executive told his team that “there are no rules in a street fight,” encouraging them to “kill” Juniper when competing for sales opportunities.

The Justice Department said that Hewlett Packard Enterprise and Juniper are the U.S.'s second- and third-largest providers of wireless local area network (WLAN) products and services for businesses.

“The proposed transaction between HPE and Juniper, if allowed to proceed, would further consolidate an already highly concentrated market — and leave U.S. enterprises facing two companies commanding over 70% of the market,” the complaint said, adding that Cisco Systems was the industry leader.

Many businesses and investors accused Biden regulatory agencies of antitrust overreach and were looking forward to a friendlier Trump administration.

Under Biden, the Federal Trade Commission sued to block a $24.6 billion merger between Kroger and Albertsons that would have been the largest grocery store merger in U.S. history. Two judges agreed with the FTC’s case, blocking the proposed deal in December.

In 2023, the Department of Justice, through the courts, forced American and JetBlue airlines to abandon their partnership in the northeast U.S., saying it would reduce competition and eventually cost consumers hundreds of millions of dollars a year. That partnership had the blessing of the Trump administration when it took effect in early 2021.

U.S. regulators also proposed last year to break up Google for maintaining an “abusive monopoly” through its market-dominate search engine, Chrome. Court hearings on Google’s punishment are scheduled to begin in April, with the judge aiming to issue a final decision before Labor Day. It’s unclear where the Trump administration stands on the case.

One merger that both Trump and Biden agreed shouldn’t go through is Nippon Steel’s proposed acquisition of U.S. Steel. Biden blocked the nearly $15 billion acquisition just before his term ended. The companies challenged that decision in a federal lawsuit early this year.

Trump has consistently voiced opposition to the deal, questioning why U.S. Steel would sell itself to a foreign company given the regime of new tariffs he has vowed.
