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.

Texas tops ranking of best state for investors in new report

by the numbers

Texas ranks third on a new list of the best states for investors and startups.

Investment platform BrokerChooser weighed five factors to come up with its ranking:

  • 2024 Google search volume for terms related to investing
  • Number of investors
  • Number of businesses receiving investments in 2024
  • Total amount of capital invested in businesses in 2024
  • Percentage change in amount of investment from 2019 to 2024

Based on those figures, provided mostly by Crunchbase, Texas sits at No. 3 on the list, behind No. 1 California and No. 2 New York.

Especially noteworthy for Texas is its investment total for 2024: more than $164.5 billion. From 2019 to 2024, the state saw a 440 percent jump in business investments, according to BrokerChooser. The same percentages are 204 percent for California and 396 percent for New York.

“There is definitely development and diversification in the American investment landscape, with impressive growth in areas that used to fly under the radar,” says Adam Nasli, head analyst at BrokerChooser.

According to Crunchbase, funding for Texas startups is off to a strong start in 2025. In the first three months of this year, venture capital investors poured nearly $2.9 billion into Lone Star State companies, Crunchbase data shows. Crunchbase attributes that healthy dollar amount to “enthusiasm around cybersecurity, defense tech, robotics, and de-extincting mammoths.”

During the first quarter of this year, roughly two-thirds of VC funding in Texas went to just five companies, says Crunchbase. Those companies are Austin-based Apptronik, Austin-based Colossal Biosciences, Dallas-based Island, Austin-based NinjaOne, and Austin-based Saronic.

Autonomous truck company rolls out driverless Houston-Dallas route

up and running

Houston is helping drive the evolution of self-driving freight trucks.

In October, Aurora opened a more than 90,000-square-foot terminal at a Fallbrook Drive logistics hub in northwest Houston to support the launch of its first “lane” for driverless trucks—a Houston-to-Dallas route on the Interstate 45 corridor. Aurora opened its Dallas-area terminal in April and the company began regular driverless customer deliveries between the two Texas cities on April 27.

Close to half of all truck freight in Texas moves along I-45 between Houston and Dallas.

“Now, we are the first company to successfully and safely operate a commercial driverless trucking service on public roads. Riding in the back seat for our inaugural trip was an honor of a lifetime – the Aurora Driver performed perfectly and it’s a moment I’ll never forget,” Chris Urmson, CEO and co-founder of Pittsburgh-based Aurora, said in a news release.

Aurora produces software that controls autonomous vehicles and is known for its flagship product, the Aurora Driver. The software is installed in Volvo and Paccar trucks, the latter of which includes brands like Kenworth and Peterbilt.

Aurora previously hauled more than 75 loads per week under the supervision of vehicle operators from Houston to Dallas and Fort Worth to El Paso for customers in its pilot project, including FedEx, Uber Freight and Werner. To date, it has completed over 1,200 miles without a driver.

The company launched its new Houston to Dallas route with customers Uber Freight and Hirschbach Motor Lines, which ran supervised commercial pilots with Aurora.

“Transforming an old school industry like trucking is never easy, but we can’t ignore the safety and efficiency benefits this technology can deliver. Autonomous trucks aren’t just going to help grow our business – they’re also going to give our drivers better lives by handling the lengthier and less desirable routes,” Richard Stocking, CEO of Hirschbach Motor Lines, added in the statement.

The company plans to expand its service to El Paso and Phoenix by the end of 2025.

“These new, autonomous semis on the I-45 corridor will efficiently move products, create jobs, and help make our roadways safer,” Gov. Greg Abbott added in the release. “Texas offers businesses the freedom to succeed, and the Aurora Driver will further spur economic growth and job creation in Texas. Together through innovation, we will build a stronger, more prosperous Texas for generations.”

In July, Aurora said it raised $820 million in capital to fuel its growth—growth that’s being accompanied by scrutiny.

In light of recent controversies surrounding self-driving vehicles, the International Brotherhood of Teamsters, whose union members include over-the-road truckers, recently sent a letter to Lt. Gov. Dan Patrick calling for a ban on autonomous vehicles in Texas.

“The Teamsters believe that a human operator is needed in every vehicle—and that goes beyond partisan politics,” the letter states. “State legislators have a solemn duty in this matter to keep dangerous autonomous vehicles off our streets and keep Texans safe. Autonomous vehicles are not ready for prime time, and we urge you to act before someone in our community gets killed.”

Houston cell therapy company launches second-phase clinical trial

fighting cancer

A Houston cell therapy company has dosed its first patient in a Phase 2 clinical trial. March Biosciences is testing the efficacy of MB-105, a CD5-targeted CAR-T cell therapy for patients with relapsed or refractory CD5-positive T-cell lymphoma.

Last year, InnovationMap reported that March Biosciences had closed its series A with a $28.4 million raise. Now, the company, co-founded by Sarah Hein, Max Mamonkin and Malcolm Brenner, is ready to enroll a total of 46 patients in its study of people with difficult-to-treat cancer.

The trial will be conducted at cancer centers around the United States, but the first dose took place locally, at The University of Texas MD Anderson Cancer Center. Dr. Swaminathan P. Iyer, a professor in the department of lymphoma/myeloma at MD Anderson, is leading the trial.

“This represents a significant milestone in advancing MB-105 as a potential treatment option for patients with T-cell lymphoma who currently face extremely limited therapeutic choices,” Hein, who serves as CEO, says. “CAR-T therapies have revolutionized the treatment of B-cell lymphomas and leukemias but have not successfully addressed the rarer T-cell lymphomas and leukemias. We are optimistic that this larger trial will further validate MB-105's potential to address the critical unmet needs of these patients and look forward to reporting our first clinical readouts.”

The Phase 1 trial showed promise for MB-105 in terms of both safety and efficacy. That means that potentially concerning side effects, including neurological events and cytokine release above grade 3, were not observed. Those results were published last year, noting lasting remissions.

In January 2025, MB-105 won an orphan drug designation from the FDA. That results in seven years of market exclusivity if the drug is approved, as well as development incentives along the way.

The trial is enrolling its single-arm, two-stage study on ClinicalTrials.gov. For patients with stubborn blood cancers, the drug is providing new hope.
