Overheard: Houston-based BIPOC, female founder finalists of 2022 share challenges overcome

eavesdropping at the houston innovation awards gala

Houston is often lauded as one of the most diverse cities in America, and that diversity is seen across its business communities as well, which includes its innovation ecosystem.

Some of the BIPOC-Founded and Female-Founded Business category finalists from the Houston Innovation Awards Gala, which will be held on November 9, shared some of the challenges they faced being in the minority of their industries and careers.

"The biggest challenge I've faced as a female BIPOC founder is having to work 2 to 4 times harder to convince individuals that I am an expert in my field, and that I know what I'm talking about when it comes to my technology and implementation."

— Asma Mirza, CEO and co-founder of Steradian Technologies. "The way I overcame it was by showing irrefutable data to support my expertise and our invention, as well as hiring a diverse team that could substantiate our claims," she adds.

"As a female founder, I used to think that I was looked at as 'less than,' compared to my male counterparts. While I still struggle with this feeling,...  I decided that the biggest hinderance in my confidence as a female founder was the lies that I was telling myself."

— Megan Eddings, founder of Accel Unite. "I felt — and still sometimes do — insecure in a room filled with male founders, not because I thought I was any less-than, but because I was thinking they thought I was less-than — before ever even meeting me," Eddings added, sharing how she tries to change her own perspective. "I now feel a responsibility to share my story, as to show other women that they are not alone, their voice matters and to keep going."

"As a BIPOC founder, it was not easy in the beginning to find the connections and network with folks that had the resources to help us with our aspirations. That was the biggest challenge in getting started."

— Enrique Carro, CEO of Blue People. "Now that we have a few clients and testimonials, we are able to pull on them to help us find new clients and connections," he continues. "But this was something that we had to really work hard on at the beginning."

"One of my fears going into the fundraising process was being seen as too weak or too fragile to lead an early-stage venture."

— Joanna Nathan, CEO of Prana Thoracic, who shares she feels this way following the loss of her son. "I found that in being transparent with potential investors, after building some trust, and speaking openly about my loss and how it has inspired me to build this company, I was able to overcome this fear."

"The biggest challenge I’ve faced as a female founder comes down to resources. Finding the capital and time to get everything done is difficult for female founders because we have a lot on our shoulders and there are systemic inequalities that make things even more difficult."

Photo courtesy

— Allie Danziger, founder and CEO of Ampersand. "I’m creating a billion dollar company, but I’m a mom of two young girls, the executive director of one nonprofit and a board member of another, and a dependable friend, wife, daughter, sister and niece, too," she continues. "Other female founders and VCs are stretched, too, so it can be difficult to connect and find time to figure it out together. I have been very fortunate and also worked really hard to find both the time and resources to make it all work."

Houston climbs to top 10 spot on North American tech hubs index

tech report

Houston already is the Energy Capital of the World, and now it’s gaining ground as a tech hub.

On Site Selection magazine’s 2026 North American Tech Hub Index, Houston jumped to No. 10 from No. 16 last year. The index relies on data from Site Selection as well as data from CBRE, CompTIA and TeleGeography to rank the continent’s tech hotspots. The index incorporates factors such as internet connectivity, tech talent and facility projects for tech companies.

In 2023, the Greater Houston Partnership noted the region had “begun to receive its due as a prominent emerging tech hub, joining the likes of San Francisco and Austin as a major player in the sector, and as a center of activity for the next generation of innovators and entrepreneurs.”

The Houston-area tech sector employs more than 230,000 people, according to the partnership, and generates an economic impact of $21.2 billion.

Elsewhere in Texas, two other metros fared well on the Site Selection index:

  • Dallas-Fort Worth nabbed the No. 1 spot, up from No. 2 last year.
  • Austin rose from No. 8 last year to No. 7 this year.

San Antonio slid from No. 18 in 2025 to No. 22 in 2026, however.

Two economic development officials in DFW chimed in about the region’s No. 1 ranking on the index:

  • “This ranking affirms what we’ve long seen on the ground — Dallas-Fort Worth is a top-tier technology and innovation center,” said Duane Dankesreiter, senior vice president of research and innovation at the Dallas Regional Chamber. “Our region’s scale, talent base, and diverse strengths … continue to set DFW apart as a national leader.”
  • “Being recognized as the top North American tech hub underscores the strength of the entire Dallas-Fort Worth region as a center of innovation and next-generation technology,” said Robert Allen, president and CEO of the Fort Worth Economic Development Partnership.

While not directly addressing Austin’s Site Selection ranking, Thom Singer, CEO of the Austin Technology Council, recently pondered whether Silicon Hills will grow “into the kind of community that other cities study for the right reasons.”

“Austin tech is not a club. It is not a scene. It is not a hashtag, a happy hour, or any one place or person,” Singer wrote on the council’s blog. “Austin tech is an economic engine and a global brand, built by thousands of people who decided to take a risk, build something, hire others, and be part of a community that is still young enough to reinvent itself.”

South of Austin, Port San Antonio is driving much of that region’s tech activity. Occupied by more than 80 employers, the 1,900-acre tech and innovation campus was home to 18,400 workers in 2024 and created a local economic impact of $7.9 billion, according to a study by Zenith Economics.

“Port San Antonio is a prime example of how innovation and infrastructure come together to strengthen [Texas’] economy, support thousands of good jobs, and keep Texas competitive on the global stage,” said Kelly Hancock, the acting state comptroller.

NRG inks new virtual power plant partnership to meet surging energy demands

Powering Up

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
