In 2019, Stephanie Campbell saw an opportunity in the market — investing in women-led startups, something that wasn't happening at the volume it should have been.

"When we looked around, we really wanted to solve the problem of why women only receive 2 percent of venture capital," Campbell says on the Houston Innovators Podcast.

Houston VC leaders to empower female founders in fintech, commerce, and care with new $36M fund

HOUSTON INNOVATORS PODCAST EPISODE 228

In 2019, Stephanie Campbell saw an opportunity in the market — investing in women-led startups, something that wasn't happening at the volume it should have been.

"When we looked around, we really wanted to solve the problem of why women only receive 2 percent of venture capital," Campbell says on the Houston Innovators Podcast.

As angel investors, Campbell and Diana Murakhovskaya, co-founders and general partners of The Artemis Fund, saw tons of promising women-led businesses.

"We were finding these incredible female founders who we felt deserved capital to bring their innovations to the market because they're solving big markets and big problems But there was a disconnect in terms of their access and network," she continues.

The other issue, as Campbell explains, was that firms that did have a female-focused angle weren't leading these early-stage rounds. That's where Artemis comes in.

"Our goal was to be the leading firm for these overlooked, underserved markets that have the ability to deliver outsized returns," Campbell says.

Almost five years and around 20 investments later, The Artemis Fund has announced its second $36 million fund to continue to fund female-led upstarts with a tech solution within fintech, commerce, and care — the three pillars The Artemis Fund invests in.

"We really wanted to solve not just problems for women, which is a lot of what we do, but for families, small businesses, and immigrants, which is how we came around to these three verticals," Murakhovskaya says.

She goes on to explain that a significant percentage of adults are a part of the "sandwich generation" — caring not only for their own children, but for their aging parents. Innovations within caregiving can help this generation with their caregiving and maintain their role in the workforce. Additionally, over half the United States workforce is employed by small businesses, but these companies usually lack access to innovative technology.

"We're thinking about what founders are building in these industries to help these businesses thrive and leave these legacy assets to their children," Murakhovskaya says.

There were so many question marks at the beginning of the pandemic, especially for startup funding. Stephanie Campbell, who manages the most active angel network as well as a venture capital fund, says no one was sure how anything was going to pan out. Now, looking back on last year, VC did ok, she says on the Houston Innovators Podcast, and the Houston Angel Network saw membership growth.

"I think that given the markets with quite a bit of liquidity, people were looking for new and interesting ways to invest and make a return," Campbell says on the podcast. "In 2020, we actually grew by 30 percent and are up to 130 members of the Houston Angel Network and are continuing to grow through 2021."

Campbell shares more of her observations on the show and what she's focused on next. Click here to read more and stream the episode.

Larry Lawson, co-founder of Proxima Clinical Research

When Larry Lawson started his career in the medical device industry, it was hard to get funding. The health tech founder and investor says if it wasn't oil or real estate, banks couldn't understand well enough to make a loan. So, he bootstrapped, raised from friends and family, and found venture capital support for his business endeavors over the years. Now, he's celebrating a $1.4 billion exit of his last business, Preventice Solutions, a deal that closed earlier this year.

The ecosystem in Houston has changed, he says, and he's seen it evolve as the Texas Medical Center grew and the Rice Business Plan Competition brought impressive student innovators from all around the globe.

"The health science community here in Houston is now known all over the world," he tells InnovationMap. "It's gonna just continue to grow and develop, and I hope to be a part of continue to be a part of it." Click here to read more.

UH student earns prestigious award for cancer vaccine research

up-and-comer

Cole Woody, a biology major in the College of Natural Sciences and Mathematics at the University of Houston, has been awarded a Barry Goldwater Scholarship, becoming the first sophomore in UH history to earn the prestigious prize for research in natural sciences, mathematics and engineering.

Woody was recognized for his research on developing potential cancer vaccines through chimeric RNAs. The work specifically investigates how a vaccine can more aggressively target cancers.

Woody developed the MHCole Pipeline, a bioinformatic tool that predicts peptide-HLA binding affinities with nearly 100 percent improvement in data processing efficiency. The MHCole Pipeline aims to find cancer-specific targets and develop personalized vaccines. Woody is also a junior research associate at the UH Sequencing Core and works in Dr. Steven Hsesheng Lin’s lab at MD Anderson Cancer Center.

“Cole’s work ethic and dedication are unmatched,” Preethi Gunaratne, director of the UH Sequencing Core and professor of Biology & Biochemistry at NSM, said in a news release. “He consistently worked 60 to 70 hours a week, committing himself to learning new techniques and coding the MHCole pipeline.”

Woody plans to earn his MD-PhD and has been accepted into the Harvard/MIT MD-PhD Early Access to Research Training (HEART) program. According to UH, recipients of the Goldwater Scholarship often go on to win various nationally prestigious awards.

"Cole’s ability to independently design and implement such a transformative tool at such an early stage in his career demonstrates his exceptional technical acumen and creative problem-solving skills, which should go a long way towards a promising career in immuno-oncology,” Gunaratne added in the release.

Houston founder on shaping the future of medicine through biotechnology and resilience

Guest Column

Living with chronic disease has shaped my life in profound ways. My journey began in 5th grade when I was diagnosed with Scheuermann’s disease, a degenerative disc condition that kept me sidelined for an entire year. Later, I was diagnosed with hereditary neuropathy with liability to pressure palsies (HNPP), a condition that significantly impacts nerve recovery. These experiences didn’t just challenge me physically, they reshaped my perspective on healthcare — and ultimately set me on my path to entrepreneurship. What started as personal health struggles evolved into a mission to transform patient care through innovative biotechnology.

A defining part of living with these conditions was the diagnostic process. I underwent nerve tests that involved electrical shocks to my hands and arms — without anesthesia — to measure nerve activity. The pain was intense, and each test left me thinking: There has to be a better way. Even in those difficult moments, I found myself thinking about how to improve the tools and processes used in healthcare.

HNPP, in particular, has been a frustrating condition. For most people, sleeping on an arm might cause temporary numbness that disappears in an hour. For me, that same numbness can last six months. Even more debilitating is the loss of strength and fine motor skills. Living with this reality forced me to take an active role in understanding my health and seeking solutions, a mindset that would later shape my approach to leadership.

Growing up in Houston, I was surrounded by innovation. My grandfather, a pioneering urologist, was among the first to introduce kidney dialysis in the city in the 1950s. His dedication to advancing patient care initially inspired me to pursue medicine. Though my path eventually led me to healthcare administration and eventually biotech, his influence instilled in me a lifelong commitment to medicine and making a difference.

Houston’s thriving medical and entrepreneurial ecosystems played a critical role in my journey. The city’s culture of innovation and collaboration provided opportunities to explore solutions to unmet medical needs. When I transitioned from healthcare administration to founding biotech companies, I drew on the same resilience I had developed while managing my own health challenges.

My experience with chronic disease also shaped my leadership philosophy. Rather than accepting diagnoses passively, I took a proactive approach questioning assumptions, collaborating with experts, and seeking new solutions. These same principles now guide decision-making at FibroBiologics, where we are committed to developing groundbreaking therapies that go beyond symptom management to address the root causes of disease.

The resilience I built through my health struggles has been invaluable in navigating business challenges. While my early career in healthcare administration provided industry insights, launching and leading companies required the same determination I had relied on in my personal health journey.

I believe the future of healthcare lies in curative treatments, not just symptom management. Fibroblast cells hold the promise of engaging the body’s own healing processes — the most powerful cure for chronic diseases. Cell therapy represents both a scientific breakthrough and a significant business opportunity, one that has the potential to improve patient outcomes while reducing long-term healthcare costs.

Innovation in medicine isn’t just about technology; it’s about reimagining what’s possible. The future of healthcare is being written today. At FibroBiologics, our mission is driven by more than just financial success. We are focused on making a meaningful impact on patients’ lives, and this purpose-driven approach helps attract talent, engage stakeholders, and differentiate in the marketplace. Aligning business goals with patient needs isn’t just the right thing to do, it’s a powerful model for sustainable growth and lasting innovation in biotech.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
