Houston innovators recognized at annual regional entrepreneur competition

Meet the winners

Eleven Houston-based executives have been crowned regional winners in the Entrepreneur Of The Year program, run by professional services firm EY.

The 11 executives now will move on to national Entrepreneur Of The Year program. National winners will be named in November.

“Every year, we are completely blown away by the accomplishments of our Entrepreneur Of The Year Regional Award winners, and 2023 is no different,” AJ Jordan, director of the Entrepreneur Of The Year program for EY Americas, says in a news release. “They are change-makers and champions of business and community, and we are so proud to be honoring them. We can’t wait to see how these leaders will continue to improve lives and disrupt industries.”

Here are the 11 local winners from the program’s Gulf South region.

Steve Altemus, president and CEO of Intuitive Machines

Intuitive Machines, founded in 2013, is a publicly traded space exploration company. The company’s upcoming mission will send the first U.S. spacecraft to the moon since 1972 as well as the first-ever commercial lunar lander. Its Nova-C spacecraft will carry commercial and NASA payloads.

Earlier this year, a joint venture led by Intuitive Machines nabbed a contract valued at up to $719 million for work on NASA’s Joint Polar Satellite System. The company, which went public in February 2023, forecasts revenue of $174 million to $268 million this year.

“Steve’s visionary mindset and ability to assemble and inspire a talented team have been instrumental in our collective success,” the company says in a statement about the Entrepreneur Of The Year award. “He consistently fosters a culture of excellence, empowering our diverse group of engineers, scientists, and visionaries to pioneer groundbreaking solutions and deliver outstanding results.”

Gaurab Chakrabarti, co-founder and CEO of Solugen, and Sean Hunt, co-founder and CTO

Solugen, founded in 2016, makes and distributes specialty chemicals derived from feedstock. The startup is reportedly valued at more than $2 billion. To date, Solugen has raised $642.2 million, according to Crunchbase.

In naming Solugen one of the most innovative companies of 2022, Fast Company noted that the carbon-negative process embraced by Solugen and the startup’s “ability to sell flexible amounts of chemicals to companies looking to lower their own footprint have helped the company make inroads in a traditionally slow-moving industry.”

Daryl Dudum and Matthew Hadda, founders and co-CEOs of Specialty1 Partners

Specialty1 Partners, which launched in 2019, supplies business services to dental surgery practices. These services include HR, recruiting, payroll, accounting, operations, marketing, business development, compliance, IT, and legal.

In 2022, Specialty1 Partners appeared at No. 72 on the Inc. 5000 list with two-year revenue growth of 2,921 percent.

“Supporting our partners and helping them grow while continuing to build partnerships with industry-leading, innovative surgical specialists is what we focus on every day,” Dudum says in a 2022 news release. “It’s not just about growing our network — we are committed to helping our partner practices grow and succeed on their terms.”

Ludmila Golovine, president and CEO of MasterWord Services

MasterWord Services offers translation and interpretation in more than 400 languages for customers such as energy, health care, and tech companies. The woman-owned business was founded in 1993.

“I’m grateful to our exceptional team and to each of our translators and interpreters who every day live our mission of connecting people across language and culture,” Golovine says in a news release about the Entrepreneur Of The Year honor.

Roger Jenkins, president and CEO of Murphy Oil

Murphy Oil is involved in oil and natural gas exploration and production primarily onshore in the U.S. and Canada, and offshore along the Gulf of Mexico. The publicly traded Fortune 1000 company, founded in 1944, racked up revenue of nearly $4 billion in 2022.

“Over the years, the company has grown and evolved to become a leading independent energy company, with strategic assets around the world,” Murphy says on its website. “All the while, we have remained true to our mission — to challenge the norm, tap into our strong legacy, and use our foresight and financial discipline to deliver inspired energy solutions.

Mohammad Millwala, founder and CEO of DM Clinical Research

DM Clinical Research, founded in 2006, runs 13 sites for clinical trials. Its areas of specialty include vaccines, internal medicine, pediatrics, gastrointestinal, psychiatry, and women’s health.

“DM Clinical Research is in a period of rapid growth with multiple new study sites added over the last two years in addition to the quadrupling of our staff to over 500 employees,” Millwala says in a January 2023 news release. “We expect this transformational growth trajectory to continue for the foreseeable future, on the road to becoming the leading independent clinical research network in the nation.”

Mark Walker, co-founder, chairman and CEO of Direct Digital Holdings, and Keith Smith, co-founder and president

Publicly traded Direct Digital Holdings owns three operating companies that offer online platforms for advertising. Three years after its founding in 2018, the company became the ninth Black-owned business to go public in the U.S.

The company posted revenue of $88 million in 2022, up 131 percent from the previous year.

“Direct Digital Holdings’ success is rooted in the hard work and commitment we have long seen in taking advantage of advertising opportunities targeting underserved communities and [that] markets often overlook,” Smith says in a news release about the Entrepreneur Of The Year award.

Omair Tariq, co-founder and CEO of Cart.com

While technically headquartered in Austin, Houston-funded Cart.com's co-founder and CEO, Omair Tariq, also was a Gulf South winner in the Entrepreneur Of The Year program.

The e-commerce company moved its headquarters from Houston to Austin in 2021. However, Tariq remains in Houston. In May 2023, Tariq delivered the commencement address to MBA recipients from Rice University’s Jones Graduate School of Business, where he earned his MBA.

Cart.com, founded in 2020, offers software and services to thousands of online merchants. To date, the pre-IPO company has raised $421 million in funding, according to Crunchbase.

“We want to be the commerce-enablement infrastructure for the largest brands in the world,” Tariq told the Insider news website in 2022.

Rice scientist earns $600K NSF award to study distractions in digital age

fresh funding

Rice University psychologist Kirsten Adam has received a $600,000 National Science Foundation CAREER Award to research how visual distractions like phone notifications, flashing alerts, crowded screens and busy workspaces can negatively impact focus—and how the brain works to try to regain it.

The highly competitive five-year NSF grants are given to career faculty members with the potential to serve as academic models and leaders in research and education. Adam’s work will aim to clarify how the brain refocuses in the age of screens, instant gratification and other lingering distractions. The funding will also be used to train graduate students in advanced cognitive neuroscience methods, expand access to electroencephalography (EEG) and for public data sharing.

“Kirsten is a valued member of the School of Social Sciences, and we are thrilled that she has been awarded the prestigious NSF CAREER,” Rachel Kimbro, dean of social sciences, said in a news release. “Because distractions continue to increase all around us, her research is timely and imperative to understanding their widespread impacts on the human brain.”

In Adam’s lab, participants complete simplified visual search tasks while their brain activity is recorded using EEG, allowing researchers to measure attention shifts in real time. This process then captures the moment attention is drawn from a goal and how much effort it takes to refocus.

According to Rice, Adam’s work will test long-standing theories about distraction. The research is meant to have real-world implications for jobs and aspects of everyday life where attention to detail is key, including medical imaging, airport security screening and even driving.

“At any given moment, there’s far more information in the world than our brains can process,” Adam added in the release. “Attention is what determines what reaches our awareness and what doesn’t.”

Additionally, the research could inform the design of new technologies that would support focus and decision-making, according to Rice.

“We’re not trying to make attention limitless,” Adam added. “We’re trying to understand how it actually works, so we can stop designing environments and expectations that fight against it.”

  • Houston-based Torres Orbital Mining (TOM),which develops autonomous excavation systems for extreme environments on Earth and the moon, enabling safe, data-driven resource recovery and laying the groundwork for sustainable off-world industry.

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

Intuitive Machines forms partnership with Italian companies for lunar exploration services

to the moon

Houston-based space technology, infrastructure and services company Intuitive Machines has forged a partnership with two Italian companies to offer infrastructure, communication and navigation services for exploration of the moon.

Intuitive Machines’ agreement with the two companies, Leonardo and Telespazio, paves the way for collaboration on satellite services for NASA, a customer of Intuitive Machines, and the European Space Agency, a customer of Leonardo and Telespazio. Leonardo, an aerospace, defense and security company, is the majority owner of Telespazio, a provider of satellite technology and services.

“Resilient, secure, and scalable space infrastructure and space data networks are vital to customers who want to push farther on the lunar surface and beyond to Mars,” Steve Altemus, co-founder and CEO of Intuitive Machine, said in a news release.

Massimo Claudio Comparini, managing director of Leonardo’s space division, added that the partnership with Intuitive Machines is a big step toward enabling human and robotic missions from the U.S., Europe and other places “to access a robust communications network and high-precision navigation services while operating in the lunar environment.”

Intuitive Machines recently expanded its Houston Spaceport facilities to ramp up in-house production of satellites. The company’s first satellite will launch with its upcoming IM‑3 lunar mission.

Intuitive Machines says it ultimately wants to establish a “center of space excellence” at Houston Spaceport to support missions to the moon, Mars and the region between Earth and the moon.
