Houston venture capitalist says it's time for more women in VC

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.

Intuitive Machines secures $175M equity investment to fuel growth

space funding

Houston-based space infrastructure and services company Intuitive Machines has secured a $175 million equity investment from unidentified institutional investors. The investors received shares of Class A stock in exchange for their funding.

Publicly held Intuitive Machines (Nasdaq: LUNR) says it plans to use the capital to help build revenue and invest in technology, including communications and data-processing networks.

“We are building a scalable infrastructure platform from low-Earth orbit to the moon and into deep space,” Intuitive Machines CEO Steve Altemus said in a news release. “With this investment, we can accelerate the integration of the combined company’s collective capabilities to deliver next-generation data, communications, and space-based infrastructure services.”

Intuitive Machines says the $175 million investment will improve its ability to secure deals for satellite systems, the proposed Golden Dome missile defense system and the proposed Mars telecommunications orbiter.

As the company pursues those deals, it’s seeking partners to develop space-based data centers.

The $175 million equity stake comes on the heels of Intuitive Machines completing its $800 million cash-and-stock purchase of Lanteris Space Systems. Intuitive Machines bought the satellite manufacturer from private equity firm Advent International.

In the third quarter, which ended Sept. 30, Intuitive Machines posted a $10 million net loss on revenue of $52.4 million.
