who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries recently making headlines in Houston across business, software, and digital health.

Entrepreneurship doesn't require a MBA from Rice University, but Dean Peter Rodriguez wants to make sure that the students who do pass through the halls of the Jesse H. Jones Graduate School of Business are well prepared for creating a successful company.

"We really want to be the deliverer of the software in people's brain of how to launch great companies and to be trumpeting the opportunities here," he says on the Houston Innovators Podcast.

Rodriguez joined the school as dean in 2016, and since then he's doubled MBA enrollment, grown the tenure-track faculty by over 40 percent, launched an online graduate degree, created an undergraduate business major, and more.

"When I came here, I thought Rice had the best strategic foundation of any university for a great business school — and a lot of that is being really closely connected to Houston and bringing in innovation," he says on the show. Read more.

Kike Oduba, founder and CEO of WellnessWits

A Houston startup aimed at transforming healthcare with solutions for chronic disease and its prevention has teamed up with IBM technology.

WellnessWits has embedded IBM watsonx Assistant into its app for both iOS and Android. By making generative AI part of the app, WellnessWits now boasts an AI-based chat functionality.

That cutting-edge aspect of the platform allows patients to get information on chronic disease more quickly than ever, even before meeting with their physician. But it helps with that, too, aiding in scheduling appointments more easily with doctors who specialize in a host of chronic maladies.

“I founded WellnessWits as a platform for shared medical appointments where doctors with large patient loads can see them in groups and offer collective shared medical experiences to people suffering from chronic conditions. The goal is to bridge this divide, leveraging the strength of digital communities to enhance the overall well-being and healthcare experiences of individuals everywhere,” WellnessWits Founder and CEO Dr. Kike Oduba, a physician and informatician, writes in a blog post.

Just nine months after its seed round, a Houston startup with a software platform for the aesthetic and wellness industry has secured $40 million in venture capital and $10 million in debt facility.

RepeatMD, a SaaS platform, announced today that it's secured $50 million, which includes a $10 million debt facility from Silicon Valley Bank. The round was co-led by Centana Growth Partners and Full In Partners with participation from PROOF and Mercury Fund, which also contributed to the seed round earlier this year.

The fast-growing company, which has over 100 employees and is looking to hire 20 more according to InnovationMap data, has a client base of 2,500 med spas, dermatologists, OBGYNs, and more across all 50 states. The startup won in the Digital Solutions category at the 2023 Houston Innovation Awards, which took place earlier this month.

“Just 9 months ago Mercury provided RepeatMD’s Seed financing round. We have quickly doubled down in its Series A because of the company's massive traction, customer adoption and Phil’s leadership,” Aziz Gilani, managing director of Mercury Fund, says in the release.

In the past year, RepeatMD reports a 2,519 percent increase in Gross Merchandise Value revenue and a 130 percent increase in SaaS revenue.

“As investors in growth-stage vertical SaaS companies, we’ve closely followed the rise of platforms that not only help practitioners run their businesses, but also drive a higher ROI go-to-market motion,” Jacob Cole, principal at Full In Partners, adds. “RepeatMD stood out both for helping clinics access higher-margin, recurring revenue, and for their customer-centric mindset.”

RepeatMD will use the funding to grow its "network of strategic partners, provide further product enhancements, and integrate AI to further amplify the patient shopping experience while scaling its Inbound Revenue Platform," per the release.

More than half of this year's startup finalists in the Houston Innovation Awards are hiring — who's looking for a job at one of the best startups in Houston?

When submitting their applications for the 2023 Houston Innovation Awards, which is taking place November 8 at Silver Street Studios, every startup was asked if it's hiring. Twenty-seven of the 35 startup honorees said yes, ranging from over 20 to just one positions open at each company.

Click here to secure your tickets to see which of these growing startups win.

Here's a look at which of the top startups in Houston are seeking new team members.

Double-digit growth

When it comes to the awards finalists looking to scale their team by 10 or more new hires, five finalists are growing rapidly.

Medical practice software platform RepeatMD, fresh off a $40 million raise — which included participation from Houston-based Mercury — is reportedly growing its team. The company, which has 115 employees already, is looking for over 20 new hires.

Female-owned business Feelit Technologies, which is using nanotechnology for preventive maintenance to eliminate leaks, fires and explosions, increase safety and reduce downtime, has 50 employees, and only three of which are in Houston – for now. The company hopes to grow its team by 12 to 15 employees in Houston alone.

Square Robot, an energy industry-focused robotics company that recently grew its presence in Houston, is hiring 10 to 30 new team members. It has 24 employees already in Houston.

Solugen, an alternative chemicals business, has around 140 of its 200 employees in Houston. The company, which has raised over $600 million to date, is hiring an additional 10 to 15 new hires.

Additionally, Blue People, also a finalist in last year's awards, is hiring 25 new employees. The company was founded in 2015 in Mexico and relocated its primary operations to Houston in 2020. Blue People, which develops software innovation for its clients, has over 150 employees — 10 of whom, including C-level executives, are based in Houston. Some of the company's new hires will be based in town.

Steady growth

Four Houston startups are hiring within the six to 10 team member range — all with fairly significant employee counts already.

A finalist in last year's awards too, Venus Aerospace, a hypersonics company on track to fly reusable hypersonic flight platforms by 2024, is again growing its team. With 48 on-site employees and 23 working remotely, Venus's team will add another five to 10 employees.

Syzygy Plasmonics, a deep decarbonization company that builds chemical reactors designed to use light instead of combustion to produce valuable chemicals like hydrogen and sustainable fuels, has 112 employees in Houston and plans to hire another eight to its team.

Lastly, Fervo Energy, which recently raised $10 million, has 63 full-time employees (34 in Houston, 29 outside of Houston) and looking to hire seven more.

The following awards finalists are looking to grow their teams by just a handful or so — between one and five — of new hires:

  • ALLY Energy, helping energy companies and climate startups find, develop, and retain great talent.
  • CaseCTRL, an AI-powered surgery scheduling and coordination software for optimized procedures.

Orion vehicle manager reflects on Artemis II, looks to 2028 moon mission

Q&A

Humanity is finally headed back to the moon after more than half a century. This year's launch of the Artemis II mission in the Orion spacecraft put four crew members in lunar orbit and tested the new ship developed by Lockheed Martin.

Everything went smoothly, safely returning astronauts home, but there is always room to improve. InnovationMap chatted via email with Orion vehicle manager Branelle Rodriguez, shortly after a talk at The Ion, for insight on how Orion might perform in the future as the next lunar landing approaches in early 2028.

InnovationMap: How satisfied are you with the way Orion operated on this past mission?

Branelle Rodriguez: Orion performed exceptionally well during Artemis II, successfully demonstrating critical spacecraft capabilities, including life support systems, displays and controls, and executing manual piloting operations. Artemis II brought humans back to the moon, achieving key exploration and scientific imagery, while validating systems essential for future Artemis missions.

IM: What is the most important thing you learned about improving Orion for the next mission?

BR: The Artemis II mission provided invaluable insights into crew operations and spacecraft performance in a deep-space environment. With every mission, NASA applies lessons learned to continuously improve Orion’s operations, validate design and ensure mission readiness. Artemis II offered our first opportunity to evaluate several new systems and gain a deeper understanding of what it is like for astronauts to live and work inside the spacecraft. The operational, technical and human factors data collected are being integrated across the program to refine future missions, reduce risk and enhance overall mission success.

IM: How has Orion helped the mission to explore space?

BR: Orion is one of NASA’s foundational elements for human deep space exploration—not only supporting the mission but serving as a core component of it. It is currently the only spacecraft capable of carrying crew on deep space missions and returning them safely to Earth from the high speeds required from the vicinity of the moon. No other spacecraft has the technology to endure the extremes that come with human deep-space travel, such as advanced environmental and life support, navigation, communications, radiation shielding, and the world’s largest ablative heat shield to protect the astronauts during reentry into Earth’s atmosphere. Orion has already taken astronauts to explore space farther than ever before—252,756 miles from Earth— and will carry crews to the moon on future missions to explore the lunar South Pole region. The astronauts’ observations, samples, and data collected on these future missions will expand our understanding of our solar system and home planet.

Houston VC funding nears $1B in first half of 2026, report says

by the numbers

Despite a weak second quarter, venture capital funding for Houston-area startups approached $1 billion in the first half of 2026, the region’s highest first-half total since 2022, according to the latest PitchBook-NVCA Venture Monitor.

This year’s first-half total of $962.4 million represented a nearly 8 percent increase over last year’s first-half total of $891.7 million. Dating back to 2016, this year’s first-half haul lags behind only 2021 and 2022 for the most first-half funding.

Houston’s year-over-year VC jump of 73 percent in the first quarter of 2026 more than made up for the year-over-year drop of 34 percent in the second quarter of 2026, according to the report.

Deal count tells a more encouraging story: Houston startups closed 102 deals in the first half, up from 93 a year earlier and the region’s busiest first half since 2022. However, the average deal size shrank, as no single funding source dominated the total.

Keep in mind that PitchBook and NVCA routinely revise quarterly numbers upward to reflect deals that were reported after a previous quarter’s data was published. So, in the case of Houston, numbers initially reported for the first quarter of 2026 may not match newly reported numbers.

Perhaps the most notable Houston-area deal announced in the first half of this year was Cart.com’s $180 million growth equity investment, led by Springcoast Partners. Cart.com is an e-commerce platform and logistics provider.

PitchBook-NVCA data shows Houston’s VC activity is growing modestly, delivering better numbers in the first half of 2026 versus 2024 and 2025, but it still sits below the highs of 2021 and 2022. This is one sign that so far in 2026, the national VC boom isn’t benefiting non-hub markets like Houston the way it’s boosting some hub markets, especially Silicon Valley and New York City.

Nationwide, AI dominated VC funding in the first half of this year. The sector made up 86 percent of VC from January through June. The report notes that the markets have still struggled to unlock IPOs, with SpaceX being the biggest exception, and few M&A deals outside health care have been significant.
