Luther Birdzell has been on a mission to democratize data for the upstream oil and gas industry since he started his company, OAG Analytics, in 2013.

For him, there's just not enough data scientists for hire to do the same thing internally for different companies. He thought of a way where he can give clients an easy-to-use platform to have access to data that could save oil and gas companies millions of dollars. So, that's exactly what he did.

"Over the past five and a half years, we've built that platform," Birdzell says. "We are currently helping to optimize over $1 billion in capital deployment around drilling and completions."

The company has grown to 25 employees and tripled its revenue last year. The team is forecasting another year of high grow for 2019.

Birdzell spoke with InnovationMap to talk about his start in software, the company's growth, and why nonprofit work has been important to him as a business leader.

InnovationMap: Did you always know you wanted to be an entrepreneur?

Luther Birdzell: When I was about two years old, my grandfather ran a meat business in New York City — in the meatpacking district, back when that area actually had meat packers. It just was in my bones from a really young age that I wanted to start a business.

IM: How did you get into software development?

LB: I studied electrical engineering in college. For my first seven years, I worked within consulting, implementing systems that made data more valuable to subject matter experts. I was primarily supporting management teams and mostly tech teams.

Then, I met the founders of iTKO, who were doing software testing for clients, and I helped them figure out a way that was complementary to what they were doing. We took a capability that can enable software developers that can help companies reduce their data center costs by a lot. It was a capability that was really restricted to specialized programing. Together we figured out how to make that a capability that anyone in an IT company used. That resulted in companies being able to higher fewer people to maintain servers, as well as reduce other costs. Companies were saving of millions of dollars per year per project.

IM: When did the idea for OAG come to you?

LB: Computer Associates bought iTKO from us in 2011. When I resigned from CA in 2013, it was very clear to me that artificial intelligence, big data, machine learning, and the cloud, were all tech ingredients for adding more value to data. Then the oil and gas business came into focus.

When I founded OAG Analytics, our mission then — and still is today — was to build a platform for the upstream oil and gas industry that enables them to manage their data, introduces world-class machine learning in minutes without having to write a single line of code, and allow them to run simulations on the resulting analysis.

IM: What makes OAG successful?

LB: My vision was to create a platform that could be trusted to support billions of dollars of capital optimization through transparency and control. A black box doesn't work for the kind of problems we're helping our customers optimize. They need something that's easy to use, simple, powerful, and also gives them complete control.

IM: What's the barrier of success for your clients?

LB: We have customers who have increased their capital efficiency on drilling programs that are about $500 million by over 25 percent, while still getting the same amount of oil out of the ground.

IM: What was the early reception like?

LB: We found a lot of interest in talking about how it works. In 2013, 2014, 2015, well over half the industry knew enough about this technology from other industries to have high confidence that it would affect the oil and gas industry one day. They were willing to spend an hour or two on what it is and how it works. But the number of companies who were really willing to invest in a meaningful way was really small.

There were companies, like EOG Resources, for example started spending millions of dollars developing this technology in house. Other companies seeing EOG and Anadarko success, raised the bar on the level of proof.

There's an increasing number of companies in the industry who realize that AI isn't a futuristic thing anymore. There are companies using it today, and the companies using it right are making more money. But, they're learning it's hard to do right. It could take years and millions of dollars to develop this yourself, but we're helping companies get up to speed in a matter of months, and our total cost for the first year is well under a million bucks to do this. They want us to train them how to use it, then act as support, rather than run it all for them.

IM: Do you plan to stay in just upstream oil and gas?

LB: We're 100 percent focused on upstream oil and gas, and always have been, but as we continue to grow, we're going to follow the market and what customers want. Repurposing our platform for other applications in oil and gas, energy, and even beyond that. We're evaluating. The vision has always been to democratize AI, and oil and gas is where we started.

IM: Do you have an exit strategy?

LB: As far as exits, I get asked this a lot. I don't believe in exit strategies. I believe in building a great company. I've seen a lot of founders make a lot of mistakes trying to cut corners to get to early exits. Our goal is to be a great company, and that starts with the right vision and then getting the right people and hires.

IM: How has Houston been as a place to have a startup in energy?

LB: Houston is unparalleled in the oil patch or the ability to support day trips. There's two airports and tons of direct flights to other cities in the oil patch. It's the only city you can cover all the other cities from with day trips. The efficiency of being able to be on site with customers is such an advantage.

There are a lot of industry experts in and around Houston, but a startup software company works very differently from an oil company. I think we have a long road ahead of us before we have an ecosystem in place to support startups and give them the best chance of success. Some of that comes from advisers, some from the ecosystem, and some part of it just takes time. But once those pieces come into play, talent follows. I think Houston is a very natural hub for energy tech.

IM: Volunteering is an important part of your business. Why is that something you've focused on?

LB: Something in the DNA of our business is giving back. We do that through direct community action. We've volunteered as a company, and we're always on the lookout for ways we can engage with and make the most contribution to the community. We do this primarily for personal reasons, but the universe has been very generous over my career with reciprocating a professional upside.

You volunteer in high school to get into college, then maybe some in college. And you might think, "oh that's for philanthropists or retired people and I'll get back to that later." But the reality of that is it feels better doing some of that now, so we do.

Experts: Houston's VC ecosystem has set the foundation — now we need scale

guest column

Fervo Energy went public earlier this summer. The Houston geothermal company priced its IPO at $27 per share, raised $1.89 billion, and opened the next morning at a market capitalization north of $10 billion. By most measures, it is the largest venture-backed cleantech IPO in history and an unambiguous win for Houston. It’s also a useful moment to look at where Houston's venture ecosystem stands and where it can go. The highlight: Houston's venture ecosystem has real foundations and, with increased company formation activity, can grow into the scale our city's ambitions deserve.

A Houston energy story in the national recovery

The recent uptick in Houston venture activity follows national trends. U.S. venture deal count contracted roughly 22 percent from its 2021 peak through 2024 before rebounding to about 16,700 rounds in 2025. Houston's 23 percent increase in VC funding from 2023 to 2024 is part of a national recovery of comparable magnitude over the same time window.

The energy sector is where Houston exhibits unique trends—and where the story turns clearly positive. (Houston's strong health and space sectors deserve their own separate consideration.) By deal count, energy-related rounds have accounted for 15 to 20 percent of Houston activity, roughly consistent over the past few years.

By capital, energy's share surged from about 14 percent in 2023 to over 60 percent in 2025, driven by a small number of large Houston-headquartered rounds, primarily in geothermal and related technologies. Fervo is the obvious anchor, but Sage Geosystems, Quaise Energy, Zeta Energy, Vaulted Deep, Applied Carbon and Mariana Minerals have all closed meaningful rounds. Houston is concentrated and accelerating as an energy capital market, an invaluable position to build upon.

From foundation to scale

The institutional pieces are in place. Greentown Labs, Activate, the Ion and others have built sector-specialized infrastructure most cities would struggle to assemble. Fervo itself is an alum of both Activate and Greentown Labs. Mercury Fund closed its $160 million Fund V, its largest ever. Houston Angel Network, GOOSE Capital, Fathom Fund, and broader pre-seed and seed capital coverage are here. The Houston $10 million-plus Series A list now includes 40 rounds since 2021, which break roughly into two eras. While 2021 to 2022 was biotech-heavy, with companies like Sporos Bioventures, RadioMedix, Cellenkos and Coya Therapeutics, 2024 to 2025 has tilted clearly toward energy, climate, and critical minerals, with Vaulted Deep, Applied Carbon, Mariana Minerals, Sage Geosystems and Ignis H2 Energy among them.

What’s less developed is the volume of seed-stage companies flowing into that capital. Imagine a dozen more Fervos coming out of that infrastructure over the next decade, each generating jobs, recycled founder capital, and the next wave of operators and angel investors. That is the kind of opportunity Houston has within reach if we build the company-formation pipeline to feed it. To be relevant on the national stage as a venture market, and to drive an economy the size of Houston's into the 2030s, the city needs to be doing closer to 20 Series A rounds per month rather than per year. That throughput implies roughly 1,000 seed rounds per year, feeding the funnel at a 20 percent to 30 percent graduation rate. Reaching such throughput depends on how many new founders Houston produces and how quickly our innovation ecosystem can help them achieve lift-off.

Houston in context

The comparative picture brings the scaling challenge into focus. Between 2021 and 2024, Houston-area startups closed between 126 and 153 disclosed venture rounds per year, against a national count between 9,854 and 14,125. That places Houston at a little over 1 percent of the U.S. deal count. For comparison, Austin ran about three times Houston's deal count each year.

At the Series A level, Houston closed between 12 and 24 rounds in any given year. The median Houston Series A across the period was about $10.7 million, compared with $15.4 million in San Francisco. Houston founders are raising fewer and smaller Series A rounds than founders in peer metros, which points directly to where Houston has the most room to grow.

The unicorn picture tells the same story. From 2021 through 2025, the U.S. produced 590 venture-backed unicorns. Four were Houston-based: Solugen and Axiom Space in 2021, Cart.com in 2023, and Fervo Energy in 2024. Adding HighRadius from 2020 brings Houston's all-time total to five. Austin added 19 over the same five-year window. The path from here is to make Houston's entries on lists like these less the exception and more the rule.

Where this leads

Houston has a real opportunity to become the deepest, most credible energy and climate capital market in the country, with the company formation, talent and operator density to support it. The data shows the foundation is already in place. Fervo, Solugen and the growing roster of energy-adjacent Series A graduates are proof. Fervo's IPO is the first of what should be many. Houston has not had a venture-backed cleantech liquidity event of this scale before, and the city now has one to reference, recruit against and build on. With increased company formation at the seed and pre-seed stages, a Fervo-scale outcome need not be a generational event in Houston, but instead, it can become part of a chain reaction powering the city's economy.
