In all the turmoil of 2020, Samantha Lewis had at least one silver lining. The former director of Goose Capital transitioned into her new position as principal at Mercury Fund.

However fortunate she feels to have her new position, she shares on the Houston Innovators Podcast this week that there's not nearly enough of women like her in venture capital.

"The bottom line is there has to be more women with check-writing abilities," Lewis says on the show. "And when there is more women with check-writing abilities, more women will get funded."

Joining the podcast at the start of Women's History Month, Lewis says that the pandemic disproportionately affected women's careers across the board — but when it comes to VC, the solution is growing the female representation at firms.

"It is up to the people in VC hiring or the institutional investors who are giving money to funds to make sure there's a woman on the investment team," she says — adding that just one isn't enough.

In her role at Mercury, Lewis is helping build up the fund's processes — something she specialized in at Goose. She's also focused on building up the portfolio around a specific theme.

"One of the things specifically that Mercury brought me over to focus on from an investment perspective is something we're calling our 'power theme,'" Lewis says. "Think about it as giving people the power to make decisions that are authentic to their values around sustainability and impact."

There have been significant changes in consumer values driven by millennials, and businesses are prioritizing sustainability and transparency in order to keep up. Lewis discusses how Houston-based Topl, which is one of Mercury's portfolio companies, has a major role to play in this space.

Another key area of interest for Lewis is fintech.

"The other piece of the theme is thinking about the democratization of financial services," Lewis says. "Legacy financial institutions have ignored large groups of our population here in America and broader for a very long time. Technology is actually breaking down a lot of those barriers, so there are all these groups that have traditionally been ignored that now technology can reach to help them build wealth."

Lewis discusses more about how Mercury Fund is at an inflection point and how the Houston innovation ecosystem is developing with intention on the episode. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

2 female Houston entrepreneurs discuss challenges women face during fundraising

women in VC

It's estimated that women make up only around 10 percent of decision makers in venture capital firms in the United States, and women-led companies only receive of a fraction of venture capital invested. And, stats aside, female entrepreneurs continue to face obstacles in the process that their male counterparts don't always share.

Kim Raath — co-founder and CEO of Topl, a Houston-based blockchain startup — and Leslie Goldman — general partner and co-founder of The Artemis Fund — discussed some of these obstacles at a virtual fireside chat for Dallas Startup Week. Here are the three challenges women face during fundraising, as Raath and Goldman discussed.

Balancing being realist with optimism

It's almost a chiche at this point — yet it still holds a great deal of truth — that women tend to be more honest than men when it comes to applying for jobs, for instance. Goldman says she's seen it plenty of times, especially when she was involved in corporate recruiting at one point in her career. Raath and Goldman agreed, women want to check off all the boxes on a requirements list.

"Men would apply if they could check just one box," Goldman says. "Women tend to be more realistic."

This trait, while noble, can be a disadvantage as it translates to the fundraising process.

Navigating unconscious bias

Raath says she's no stranger to discrimination for being a woman. In the chat, she tells a story of when she was a girl and the woman's track event she was supposed to run was canceled. She had her heart set on getting to nationals, so her father lobbied for her to get a chance to run in the boy's race. Eventually, they let her and she came in second place.

She continued to observe moments like this throughout her schooling, especially when she started studying male-dominated studies like economics and statistics — Raath now has a master's and a Ph.D from Rice University. When recently raising money for Topl's latest round, her observational and statistical mind picked up on something. Raath explains that there are two types of questions a VC might ask you — preventative vs. promotional. An example she gives for each is:

  • Preventative: "How many daily users do you have?"
  • Promotional: "How do you look to acquire users?"

"About three months in, I started realizing that I'm constantly getting these preventative questions. So, I did a little research," Raath says, explaining that she found that women are more likely to get these preventative questions. "Now, every preventative question I got, I started answering with a promotional answer."

It's the same unconscious bias as how a young male entrepreneur might be considered, "young and promising," while a woman with the same resume would be considered, "young and inexperienced."

Creating a supportive network

Raath and Goldman discussed the importance of women surrounding themselves with supportive networks made up of both women and men. On one hand, it's key to have fellow female entrepreneurs or investors who have been in your shoes before or whom you can give advice to — Raath says she created "woke woman wine nights" with her interns this summer.

On the other hand, having men in your network who can act as advocates — like Raath's father was as well as her male co-founders whom she says are great supporters — is crucial too.

"I have been surrounded by some amazing male counterparts," Raath says. "That's the other side of this is finding male champions."

Houstonian fosters collaboration and mentorship for women in venture capital

HOUSTON INNOVATORS PODCAST EPISODE 46

When Sandy Guitar saw that Austin had a group of women in venture capital group that promoted collaboration and networking, she knew Houston had to have one too.

Guitar, who is the managing director of the HX Venture Fund, connected with the Austin group, picked their brains and asked for advice on starting a local iteration, and recruited a few fellow female VC experts in town — and the rest is history.

"There's a part of us as women that understands necessarily that work and life combine," Guitar says on this week's episode of the Houston Innovators Podcast. "Our lives as women don't allow us to segment our lives. The truth is those parts of our lives come together. The more we can do that, the more we can build networks that help us achieve everything we want both professionally and personally."

Now, over a year later, the Women Investing in VC in Houston group has grown to over 30 members — so much that their virtual visits are broken into smaller groups. The group boasts diversity and has representatives across types of funds. To join, women must simply live in Houston and be a venture capital investor. Other than that, the group is unstructured and casual, which fosters an environment where members are allowed to ask a stupid question or speak up on something personal, as Guitar says.

"When you have no dues and very little formality, no structure, no pressure to attend — it's in that setting that you actually build trust. Organically, the friendships come together," she says. "That's what it's really about."

While the group had pre-pandemic beginnings, the model of mentorship and networking is more relevant now than ever. Men and women alike, Guitar says, are not able to silo work and life as we work from home and practice social distancing.

"COVID has made us vulnerable in an entirely new set of ways," she says. "We use our support groups — whatever they are — to help us."

Guitar discusses the group and how what the venture capital industry needs to do to evolve into a more welcoming space for women in the episode of the podcast. You can listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Axiom Space officially redomiciles its headquarters in Texas

space city

Axiom Space has claimed Houston as its operational home since 2016. And now it can call Texas its official legal headquarters, too.

The spacetech company, which is developing the first commercial space station, Axiom Station, has officially redomiciled its legal headquarters from Delaware to Texas, Axiom announced this week.

Axiom employs approximately 700 people, the majority of whom are in Texas, according to a news release. Its Assembly Integration and Test Facility was built as an anchor of the Houston Spaceport, and the company is also developing next-generation spacesuits at its Houston-based spacesuit lab.

“Texas has demonstrated, consistently and deliberately, that it wants innovative companies to thrive here and has built the policy and regulatory framework accordingly,” Jonathan Cirtain, CEO and president of Axiom Space, said in the release. “For Axiom Space, establishing Texas as both our operational and legal home puts us squarely in a state that understands our mission, supports our industry, and shares in what we are working to achieve.”

Axiom touts Texas's "financial and infrastructural commitments" to the space economy as reasons for the move, including programs and grants from organizations such as the Texas Space Exploration & Aeronautics Research Fund (SEARF), the Texas Space Commission, and the Texas A&M Space Institute.

Axiom was previously awarded a $5.5 million SEARF grant for the development of its orbital data center capabilities last year.

The news comes as energy giant ExxonMobil also announced concrete plans to redomicile its legal headquarters in Texas. Exxon's board of directors unanimously recommended redomiciling in the Lone Star State in March. The company announced this week that the move would become official July 1. The company's operational headquarters is based in Spring, Texas, a Houston-area suburb.

Houston cleantech, space startups named to World Economic Forum cohort

top honor

Two Houston-based startups have been selected to join the World Economic Forum's Technology Pioneers community.

The two-year program aims to help mission-driven, early-stage start-ups scale their innovations through multi-stakeholder initiatives, co-creating partnerships and other gatherings for community members. One-hundred startups are selected each year from around the globe, this year hailing from 23 countries and working in AI, energy, space, biotech markets and more.

Cleantech startup Vaulted Deep was one of 11 energy and climate companies to be named to the cohort. Julia Reichelstein and Omar Abou-Sayed founded the company in 2023. Its technology injects excess organic waste underground to remove carbon dioxide from the atmosphere.

Last year, Vaulted Deep inked a 12-year deal with Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

The startup has earned several accolades in recent years, including a No. 3 spot on Fast Company’s list of the World’s Most Innovative Companies of 2026. It was also recently named to market intelligence and advisory firm Cleantech Group's annual Global Cleantech 100 list for a second year in a row.

"Waste management is one of the world's great invisible infrastructure systems ... The need for new infrastructure is growing as disposal challenges become more complex and regulations evolve. Vaulted is building the first new disposal pathway for organic waste in decades by putting it deep underground, permanently," the company shared in a LinkedIn post. "This year, we're joining the World Economic Forum's 2026 Tech Pioneers alongside innovators working on the many interconnected challenges shaping our future."

Houston-based Venus Aerospace was also selected to join the cohort, along with six other spacetech companies. The company was founded in 2020 by Sassie and Andrew Duggleby.

The startup specializes in next-generation rocket engine propulsion as a cleaner alternative to traditional combustion engines. The company's rotating detonation rocket engine (RDRE) burns fuel more efficiently and completed a successful high-thrust test flight last year. Venus says it’s the only company in the world that makes a flight-proven, high-thrust RDRE with a “clear path to scaled production.”

"Frontier technologies matter most when they expand what people, industries, and nations can do," Sassie Duggleby, co-founder and CEO of Venus, said in a news release. "For Venus, RDRE does not just represent a more efficient engine. It is a foundation for faster movement, more capable space systems, and new forms of connectivity across the planet. Being named a Technology Pioneer validates the potential of this technology to help shape a future where distance is less limiting."

Houston Methodist receives record $110M gift, names future tower

historic gift

Houston Methodist has received the largest gift in the health system's history to establish new funds for neurological, neuroscience, and women’s health research and treatment.

The $110 million gift comes from Houston-based The Brockman Medical Research Foundation, which supports education and research in the science, medicine and healthcare fields. In response, Houston Methodist announced that it will name its forthcoming 26-story hospital facility the Brockman Centennial Tower.

The tower’s entrance will be named the Anna Margaret Bellows Centennial Hall to honor Anna Margaret Bellows, a young camper who died during the Camp Mystic flooding last summer.

“This extraordinary gift accelerates discovery and transforms how care is delivered,” Dr. Marc Boom, president and CEO of Houston Methodist, said in a news release. “We are grateful to The Brockman Medical Research Foundation for its incredible generosity and vision that will help change the lives of generations of patients. Naming Centennial Tower in recognition of this gift reflects the scale of this commitment and its impact on the future of neuroscience, neurological care and women’s health.”

The gift will be divided into two parts:

  • $100 million will go toward creating an innovation fund within the Houston Methodist Academic Institute and the Houston Methodist Neurological Institute
  • $10 million will be devoted to Houston Methodist's Department of Obstetrics and Gynecology

“This tremendous gift will accelerate translational research that broadens our understanding of neurological and other diseases,” Dr. Jenny Chang, president and CEO of the Houston Methodist Academic Institute, added in the release. “It will allow us to leverage state-of-the-art platforms to detect, diagnose and deliver therapeutics, keeping patient care at the center of our mission.”

The Brockman Centennial Tower is expected to open next year in the Texas Medical Center. Spanning more than 1 million square feet, it will house 400 patient beds, an expanded emergency department, new operating rooms and a rooftop garden. It will be connected to Houston Methodist's flagship Paula and Joseph C. “Rusty” Walter III Tower, which opened in 2018. The Centennial Tower was estimated to cost $1.4 billion when announced in 2022.

In addition to the news of the Brockman gift, Houston Methodist also announced this month that it has launched the Houston Methodist Center for Cell and Gene Therapy and tapped an internationally recognized scientist as its leader.

The new center is focused on discovering and developing innovative and cost-effective therapies for a variety of congenital and acquired diseases, including cancer, HIV and cardiovascular disease.

Dr. Malcolm Brenner has been named as the center's inaugural leader and will assume the role starting in October. He will work alongside scientists and support staff from Baylor College of Medicine and Texas Children's Hospital.

Brenner is a professor of pediatrics, medicine, molecular and human genetics and translational biology at Baylor College of Medicine. He is known for making early advances in using bone marrow transplantation as a form of cell therapy and in engineered immune-cell treatments for cancer and infections, according to a release from Houston Methodist.

“Malcolm Brenner is a pioneer in the field of cell and gene therapy and is uniquely qualified to lead Houston Methodist’s research efforts in this field,” Chang added. “His vision and leadership will play a pivotal role in advancing our work in this space.”
