Ahead of Houston Energy & Climate Startup Week, we are speaking with the contributors shaping Houston’s energy startup ecosystem: the founders, mentors, and investors behind both its formal programming and the informal moments where much of the real work happens. First up is John Jeffers, who is an investor, advisor, and board member. What follows is a working philosophy: why strong technical teams misjudge their companies, why a competitive industry still collaborates, and why Houston is where companies with bold ideas come to be tested. See John’s video interview on Ion District’s LinkedIn and Instagram.

You came to Houston for your master’s at Rice. From then to now, how have you been involved in the Energy and Startup Ecosystem? 

I came to Houston and it took me to Antarctica. There, I worked with a small group of researchers, each with our own project, supporting each other no matter whose project was on the line. When you’re five thousand miles from civilization, you learn to solve problems on the fly. I took that same mindset to my oil and gas career. Coming in as the new guy who didn’t know things were “impossible” meant I kept pushing at the edges of what people assumed was possible, which is what put me on the international frontier exploration side. My advice to founders today comes straight from that: don’t let someone else’s map of ‘impossible’ become yours.

What pulled you towards the startup world, and what is it that the technical founders need?  

I was pulled into the startup ecosystem through the Rice Alliance Energy Tech Venture Forum. I brought the same risk-management mindset from frontier exploration into the startup system. You don’t know very much when you start: you have an idea, and you have to test it. Much like when you run a startup. This forces a certain discipline with money because you’re not actually spending it to produce oil and gas; you’re spending it to learn as much as you can, as fast as you can, before you commit to the bigger investment.

I ended up teaching a year-long innovation course at the University of Houston. That’s when I boiled it down to the rule I give founders now: learn as much as you can, as fast and as cheaply as you can, about the things that matter most.

I specifically have zoomed in on the 2 problems that startups face where founders need most help:

1. Engaging with medium- large corporations that expect 30-page contracts and $100 million insurance policies
2. Fundraising for deep tech  

Having spent thirty years de-risking ideas, where did you find the founders were/ are getting it wrong?

Through my involvement with Rice Alliance, I have mentored some very talented, motivated people that needed a sounding board for strategies or connections in the industry. The pattern amongst all the founders is remarkably consistent: brilliant technical teams who keep perfecting the thing instead of finding the customer. The technology’s usually already good enough. What they don’t know is: Who’s going to buy it, at what price, and whether they can deliver it profitably 

I saw this play out with a founder who was building a methane-monitoring system. Her frame of reference was landfill gas, but the obvious market was oil and gas. Her actual starting point, as she told it, was: “I drove past an Exxon station once, so I guess that’s oil and gas, right?” Within days, she had two dozen people she could call. She built the company quickly after that and exited successfully. 

Could a founder do this somewhere else?

Houston’s got a reputation for being scrappy and pragmatic. A lot of people come here as blue-sky dreamers, and what we provide them with is some grounding. That grounding is real because the universities back it up, Rice and UH deep in engineering and natural sciences, A&M and Prairie View adding diversity to these sciences, St. Thomas and Houston Christian bringing the humanities perspective. 

Where does all of that actually come together for a founder to access it?

There has to be a place where they physically collide, and that’s Ion District. But it is the Rice Alliance’s network that ensures those collisions don’t have to happen only within those four walls. It’s this loose fabric connecting hundreds of people across the city, most of them with a long history in energy, who are always ready and willing to give their time.

A lot of those people are, technically, competitors, but they come together. That’s the part engineered by this city and its organizations. The energy systems are so large and so complex that no single company, no matter how big, can do it all alone. That’s the spirit that actually makes the Ion and Rice Alliance work so well – collaboration built right on top of competition. A rising tide lifts all. 

Capwell in Greentown Labs is the example I always come back to. They came out of a university outside Houston, and they could’ve built anywhere. But the capabilities and their customer base was here. So they got the company off the ground fast. 

What do you hope comes out of Houston Energy and Climate Startup Week this year?

It kind of ties right back to what we were just talking about with Ion and the Rice Alliance concentrated in one week. Connections are the biggest thing. Also, the exchange of perspectives between Houston and the rest of the world.

We have got some good anchor events, and the Rice Alliance Energy Technology Venture Forum is the capstone for me. But the anchor events aren’t the only thing; they are the glue in between. All the networking that looks like filler on the schedule- that’s where the magic actually happens.

You get enough people with different perspectives into one place for a week; you don’t have to engineer what comes next. It just happens.

People come first. The things come after.

Bio: John Jeffers’ connection to Rice goes back to 1985, when he came to Houston to pursue a master’s in geology. He has worked 30+ years on both sides, as a corporate insider and as a startup ally. His first involvement with Rice Alliance was in 2017-18 through Venture Forums, which became an annual commitment. In 2020, when he left his corporate job, he switched sides to become a bridge between these two worlds.

Houston Energy & Climate Startup Week runs September 14–18, 2026, bringing together energy and climate startups, investors, and industry leaders from across the region and beyond. Stay tuned on Instagram and Linkedin for event updates.
