Houston, an important hub for healthcare and life-science ventures, continues to see significant support for those sectors. And the city’s infrastructure around life-sciences and healthcare continues to grow. Most recently, the Texas Medical Center announced an increase in the size of its TMC Venture Fund to $50 million from $25 million. The Venture Fund was launched in 2017 to invest in Houston-area medical technology organizations and initiatives.

The city is on the leading edge when it comes to investing in digital health startups and the entrepreneurs who launch them. Nationwide, venture capital financing for medtech increased 67 percent from 2017 to 2021, with total financing approaching $20 billion, according to Deloitte’s new study, New Strategies for MedTech Startups. Financing deals for medtech organizations in Texas totaled $555 million during that time. That’s the fourth-largest total in the country, behind California, Massachusetts, and New York.

What investors are paying the most attention to are late-stage diagnostic and digital companies, according to the report. Among the hot spots for funders: AI technologies, at their highest funding level in five years; in-vitro diagnostics (IVD) and healthcare IT, both of which have dominated medtech fundraising over the last decade, raising $48 billion and $36 billion, respectively.

What could use more support are early-stage companies, the kind that get seed and series A funding. The study found that funding for them has dipped to 23 percent of total medtech VC funding in 2021 from 27 percent in 2017. Why? Yields are lower for medtech investors compared to other sectors, and reimbursement for new technologies can be difficult to achieve, meaning companies can’t get paid for their goods or services. Additionally, pandemic-induced factors, such as supply-chain issues, have also impacted funding.

Ever creative, many Houston-area early-stage entrepreneurs are looking to alternative kinds of finance, including pre-revenue IPOs and SPACs to gain entry to public markets as well as build-to-buy, where a medtech incumbent takes an ownership stake with an option to buy the company. They’re also looking to family office investment groups—family-run, generally mission-driven investors who tend to be less formal than VC funds—for financial support.

And venture capital is more than willing to invest in companies, according to the investors interviewed for the Deloitte study. Companies with strong management teams, scalable technologies that address unmet needs for a large market, technologies with low regulatory and reimbursement barriers, and products that can reduce the overall cost of healthcare will catch their attention. Bonus points for efficient, forward-looking companies, too.

Attention to these smaller firms is crucial and necessary, given that 94 percent of the 15,500-plus medtech firms in the United States are pre-revenue or have no revenue at all. Houston is home to plenty of these smaller firms with big potential. Investors would do well to look at them as long-term investments and support them by helping to lay the groundwork for regulatory and reimbursement success, in addition to investing financially.

In adopting this approach, the VC community can make significant strides towards bolstering an already strong medtech ecosystem in Houston.

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
