Several years ago, Kelsey Hultberg decided to make a pivot. Looking for a role with career growth opportunities, the communications professional thought she'd find something at an oil and gas company, but then she met John Berger, founder and CEO of Sunnova, who was looking for someone to stand up their communications team amidst the solar energy company's growth.

"He hooked me," Hultberg shares on the Houston Innovators Podcast. "He said, 'I've got big plans for this company. I see where this energy industry is going, I see that we're prime for a transition, and I want to take this company public.' And I started a few weeks later."

Hultberg has been telling the story for Sunnova — which equips customers with solar and storage technology, providing them with energy independence — ever since, through scaling, new technologies, and its IPO in 2019.



Each phase of the company represented different challenges for Hultberg and her communications team. As she explains on the podcast, consistently conveying a strong message is key in any industry, but especially energy.

"Communication is critical," Hultberg says, "having a strategy and really being able to articulate who you are, what you stand for, what is your mission, what is your vision — and really beyond that, what is your strategy for how you move forward. ... You can never say the same thing to the same people too many times, especially when you're a company that some people have never heard of before."

And while there's a unique challenge to communications for energy transition companies, Hultberg says she views it as a huge opportunity as long as you have the right structure in place.

"Of course communications and being as strategic as possible with the story that you're telling and the narrative that you're weaving for your different audiences, but then you layer on an industry that's rapidly changing and is tumultuous at times," she says. "Being able to come back to the core mission and values is really incredible."

Hultberg says that when she originally joined the team in 2017, she thought a solar energy company in Houston was an interesting choice — and it was. Texas was not one of Sunnova's biggest markets at the time, Hultberg explains, but things are different now.

"Over the last couple of years, especially after Winter Storm Uri, where you saw a lot of people go without power. ... We had a lot of customers say, 'That can't happen again,'" she says. "You're seeing the adoption and uptick in solar in storage because they are looking for grid reliability and affordability and they aren't getting it from their utility providers."

3 Houston innovators to know this week

Who's who

Houston is still — but most accounts — emerging as a tech and innovation hub, which could seem to mean that the startups that make up the innovation ecosystem reside in early stages of business scale.

However, this week's sampling of Houston innovators to know demonstrate the scope in scale of Houston's companies — from a CEO to a newly public company and recently hired CEO of a rapidly scaling software company to a health tech leader fresh out of the gates.

Taking a company public brings on a slew of changes. One that might be overlooked is the change for the leader of that company. John Berger —CEO of Sunnova, a Houston-based solar energy company that went public last summer — joins the Houston Innovators Podcast to discuss the changes and where his company is headed.

Transitioning from a private company CEO to a public company CEO has been eye opening, Berger says on the podcast, joking that he now has to watch what he says. But change is ultimately something Berger says he embraces.

"I really look at myself and how I can change myself," Berger says. "I'm a different CEO today than I was 12 months ago, and hopefully I'll be a different CEO in 12 months, because the company demands it." Read more and stream the episode here.

Mary Beth Snodgrass, co-founder of Healthiby

Mary Beth Snodgrass is convinced she can help people make life-enhancing changes that affect health and financial situations because, well, science.

The co-founder of Healthiby created the platform to use financial incentives to drive positive health and wellness decisions. The Houston company is in pilot mode but has plans to expand.

"What we're really focused on this year is, in addition to our incentives, digital content and coach guidance, is making sure that participants are engaging among themselves," Snodgrass tells InnovationMap. "Science shows there are benefits to surrounding yourself with other people who share similar health goals." Read more.

Gene Austin, CEO of Quorum Software

A new CEO is tasked with exponential growth at a Houston-based software company. Gene Austin joined Houston-based Quorum Software last year at a time of rapid M&A activity.

The energy industry software solutions provider, which is a portfolio company of California-based private equity firm Thoma Bravo LLC since 2018, has big plans to continue the exponential growth with more acquisitions that diversify their portfolio of services and a Houston office expansion later this year. According to Austin, he expects this growth spurred by M&A activity to double Quorum's revenue of $200 million in the next 3 to 5 years.

"We are always thinking about how to best serve our customers," Austin says. "We've made millions of dollars of investments in our support organization and cloud team services that are foundational to reinvigorate innovation and help our customers see how the future can unfold for them."

Houston solar energy exec shines light on company growth and IPO

HOUSTON INNOVATORS PODCAST EPISODE 15

It was all about the timing for John Berger, founder and CEO of Sunnova, a Houston-based residential solar energy company.

When he founded his company in 2012 in Houston, solar energy wasn't the trendy sustainability option it is today, but Berger saw the potential for technology within the industry. So, with a lot of perseverance and the right team behind him, he scaled Sunnova through nationwide expansion, billions of money raised, and a debut on the stock market last July — something that also happened with great timing.

About 72 hours after Sunnova went public last July, the Federal Reserve System announced it was going to cut rates. Additionally, Sunnova's IPO occurred ahead of WeWork's failed IPO.

"We went public in a market that still isn't back open again, I think, for IPOs," Berger says on this week's episode of the Houston Innovators Podcast. "We had pretty good timing when we went out the door."

However great the timing was, Sunnova's success is built on the hard work and skills of the company's employees, Berger explains on the podcast, and now running a public company requires a dynamic leader.

"I really look at myself and how I can change myself," Berger says. "I'm a different CEO today than I was 12 months ago, and hopefully I'll be a different CEO in 12 months, because the company demands it."

In the episode, Berger lifts the curtain on Sunnova's IPO, explains where he sees the solar energy industry headed, how battery storage technology has evolved, and why he's not worried about who ends up in the White House.

Houston-founded startup raises $1.2M and moves headquarters to Detroit

moving forward

Houston-founded ChurchSpace, known as the Airbnb for churches, has formed an official partnership with the City of Detroit and will relocate its headquarters.

The announcements come as the company successfully closed a $1.2 million oversubscribed funding round. The round was led by California-based Black Ops Ventures, with participation from Michigan Rise and Dug Song of Minor Capital, who is also the founder of the Song Foundation, another Michigan-based organization.

"This raise is more than a business milestone—it's a testament to what happens when strategy meets faith. In today's climate, raising capital takes grit and resilience—especially without deep networks or traditional access. By God's grace, doors have opened, and our mission is clearer than ever. Now, with capital in hand, we're building boldly toward a future where the Church isn't just surviving—but leading community transformation," Emmanuel Brown, co-founder and CEO of ChurchSpace, said in a statement.

In Detroit, ChurchSpace plans to activate underutilized church campuses as micro-logistics spaces for food distribution and retail partnerships, as well as last-mile delivery centers. To kick off its relocation, ChurchSpace will host a Detroit Pastor Meetup on July 19.

"We welcome ChurchSpace's investment in Detroit and the jobs and innovation it will bring," Detroit Mayor Mike Duggan added in the release. "Our faith community has long been a critical backbone of our neighborhoods. Through ChurchSpace's groundbreaking work, they will continue to be anchors of opportunity and resilience in our city's future."

ChurchSpace was originally founded to convert underutilized church real estate into event, meeting and commercial kitchen space to boost revenue and relieve financial burden while remaining compliant with IRS regulations for non-profits. The company participated in the inaugural cohort of the AWS Impact Accelerator for Black Founders, which included a pre-seed fundraising campaign and a $125,000 equity injection from Amazon in 2022. It was also one of two Houston companies to receive $100,000 as part of the Google for Startups Black Founders Fund that same year.

The company reports that its platform in Texas has generated up to $100,000 annually in new revenue that was reinvested into church ministries, food programs and community initiatives.

"What we built in Houston was more than technology—it was transformation. We expanded our purpose and packaged proven strategies to help churches thrive, transform communities, and even combat food insecurity," Day Edwards, co-founder and president of ChurchSpace, added in the statement. "Now, with prayer and the support of our team and investors, we're bringing that same impact to Detroit—to help churches, communities, and small businesses redefine pulpits and rediscover communal possibilities."

Houston healthtech leader launches clinical trial for innovative anxiety-treating device

making waves

Houston-based Nexalin Technology’s proprietary neurostimulation device will move forward with a new clinical trial evaluating its treatment of anxiety disorders and chronic insomnia in Brazil.

The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices have been shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria university hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia, according to a news release.

“Brazil is an important emerging market for mental health innovation, and this collaboration marks our first IRB-approved study in the region,” Mike White, CEO of Nexalin, said in the release.

The study will be led by Dr. Andre Russowsky Brunoni, who specializes in neuromodulation and interventional psychiatry. He currently serves as director of the interventional psychiatry division at IPq-HCFMUSP and this summer will join UT Southwestern in Dallas and its Peter O’Donnell Jr. Brain Institute as a professor of psychiatry.

The Phase II study plans to enroll 30 adults in São Paulo and assess the efficacy of Nexalin’s non-invasive deep intracranial frequency stimulation (DIFS™) of the brain in reducing anxiety symptoms and improving sleep quality, according to the company. Using the Hamilton Anxiety Rating Scale (HAM-A), the trial’s goal is a reduction in anxiety symptoms, and assessments of sleep onset latency, total sleep time, overall sleep quality, depressive symptoms and clinical impression of improvement. The company plans to share results in a peer-reviewed scientific journal.

“Anxiety and insomnia are very common conditions that often occur together and cause significant distress,” Brunoni added in the news release. “In this study, we are testing a new, non-invasive brain stimulation technology that has shown promising results in recent research. Our goal is to offer a safe, painless, and accessible alternative to improve people’s well being and sleep quality.”

The Nexalin Gen-2 15-milliamp neurostimulation device has been approved in China, Brazil, and Oman.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population. It also recently raised $5 million through a public stock offering. Read more here.
