Houston energy-focused AI platform raises $5M in Mercury-led seed round

fresh funding

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.

Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.

“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”

Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.

Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.

Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.

Collide says its approximately 6,000 platform users span 122 countries.

Houston energy workforce-focused startup raises $2.5M seed funding

cha-ching

With $2.5 million in fresh funding, Digital Wildcatters is on its way to keep empowering the evolving energy workforce.

Digital Wildcatters, a Houston company that's providing a community for the next generation of energy professionals, has closed its seed plus funding round at $2.5 million. The round by energy industry veteran Chuck Yates, who also hosts his podcast "Chuck Yates Needs a Job" on the Digital Wildcatters' podcast network.

"Our industry's survival depends on recruiting the next generation of energy workers. We must adapt to their digital, content-rich world, as we currently lag behind, like a VHS tape in a Netflix world. Digital Wildcatters is our path to modernization," Yates, based in Richmond, Texas, says in the news release.

Diamondback Energy and ProFrac also contributed to the round, which closed on December 1 and follows up on the company's $2 million seed round raised from angel investors in 2021.

The fresh funding will go toward further development and commercialization of Collide, an energy industry professional networking app, which launched this fall. The app aims to help advance and support the industry through professional development connection, job portal, and an AI-backed content search engine for industry information.

"Our mission is to empower the next generation of energy professionals to advance their careers and collaboratively address the global energy crisis," Collin McLelland, co-founder and CEO of Digital Wildcatters, says in the release. "We are incredibly grateful to have an investor base that not only believes in our vision but also supports our endeavor to craft innovative products that will redefine the future of the energy industry."

McLelland co-founded Digital Wildcatters with Jake Corley. The two started the Oil and Gas Startups podcast in 2019.

The Digital Wildcatters have created a platform for individuals to get their questions answered by experts and a space for companies seeking qualified talent. Collide is structured to ignite the next generation of energy innovators, as Collin McLelland, co-founder and CEO of Digital Wildcatters, tells EnergyCapital.

“If you look at what we’ve done historically with Digital Wildcatters, we’ve built an extremely engaged community of energy professionals — it’s a next generation community, very young forward thinking professionals that are working towards solving the world’s energy crisis,” McLelland says.

The roll out of Collide has been intentionally gradual, McLelland says because they want to shape the user experience based on feedback from ongoing focus groups. Currently they have about 1,000 users and are examining how they can make the app valuable to them before providing the platform to a wider audience.

McLelland says there are two major issues within the energy sector that Collide hopes to address — a lack of knowledge about energy verticals and difficulty recruiting talent.

“What we really see with our platform is being able to bring people together where if you want to find a piece of information, you need to find a subject matter expert, or if you want to find your next job, it happens on the Collide platform,” McLelland says. Read the full story.

Houston-based, energy-focused digital media company launches networking app

Wilding out

A Houston-based media organization dedicated to covering the energy industry has officially launched the beta program of their networking app.

After producing zanily named energy podcasts like “Big Digital Energy” and “What the Funk,” Digital WIldcatters is trying to bridge the hiring gap in the energy industry. By providing a platform for individuals to get their questions answered by experts and a space for companies seeking qualified talent, Collide is structured to ignite the next generation of energy innovators. Collide is currently available for users in both the Apple App Store and Google Play Store.

Collin McLelland, co-founder and CEO of Digital Wildcatters, says he aims to expand their professional community through this networking platform. Rather than being a transition away from Digital Wildcatters’ roots as a digital media organization McLelland explains Collide is an integration of the community they have built through podcasts and events into an interactive platform.

“If you look at what we’ve done historically with Digital Wildcatters, we’ve built an extremely engaged community of energy professionals — it’s a next generation community, very young forward thinking professionals that are working towards solving the world’s energy crisis,” McLelland shares.

The roll out of Collide has been intentionally gradual, McLelland says because they want to shape the user experience based on feedback from ongoing focus groups. Currently they have about 1,000 users and are examining how they can make the app valuable to them before providing the platform to a wider audience.

McLelland says there are two major issues within the energy sector that Collide hopes to address — a lack of knowledge about energy verticals and difficulty recruiting talent. McLelland attributes the information gap to how expansive the energy sector is, incorporating beyond oil and gas, everything from renewables to lithium mining. Similarly, by zeroing in on the energy sector, McLelland believes Collide can draw upon the network of talent Digital Wildcatters has already cultivated to tackle recruiting issues.

“What we really see with our platform is being able to bring people together where if you want to find a piece of information, you need to find a subject matter expert, or if you want to find your next job, it happens on the Collide platform,” McLelland says.

Unlike other hiring platforms, Collide offers users the opportunity to look for information about the energy sector by integrating all of Digital Wildcatters’ podcasts and videos into a content search engine. This program is part of their DW Insight subscription product which also has a startup database with overviews of various companies, from their demos to a portal to contact them.

“We hope someday that we’ll have this knowledge base that can be searched and queried to where if you want to find out any piece of information, you’ll be able to find it on (DW Insight),” McLelland explains.

McLelland co-founded Digital Wildcatters with Jake Corley. The two started the Oil and Gas Startups podcast in 2019.

Houston geothermal company raises $97M Series B

fresh funding

Houston-based geothermal energy startup Sage Geosystems has closed its Series B fundraising round and plans to use the money to launch its first commercial next-generation geothermal power generation facility.

Ormat Technologies and Carbon Direct Capital co-led the $97 million round, according to a press release from Sage. Existing investors Exa, Nabors, alfa8, Arch Meredith, Abilene Partners, Cubit Capital and Ignis H2 Energy also participated, as well as new investors SiteGround Capital and The UC Berkeley Foundation’s Climate Solutions Fund.

The new geothermal power generation facility will be located at one of Ormat Technologies' existing power plants. The Nevada-based company has geothermal power projects in the U.S. and numerous other countries around the world. The facility will use Sage’s proprietary pressure geothermal technology, which extracts geothermal heat energy from hot dry rock, an abundant geothermal resource.

“Pressure geothermal is designed to be commercial, scalable and deployable almost anywhere,” Cindy Taff, CEO of Sage Geosystems, said in the news release. “This Series B allows us to prove that at commercial scale, reflecting strong conviction from partners who understand both the urgency of energy demand and the criticality of firm power.”

Sage reports that partnering with the Ormat facility will allow it to market and scale up its pressure geothermal technology at a faster rate.

“This investment builds on the strong foundation we’ve established through our commercial agreement and reinforces Ormat’s commitment to accelerating geothermal development,” Doron Blachar, CEO of Ormat Technologies, added in the release. “Sage’s technical expertise and innovative approach are well aligned with Ormat’s strategy to move faster from concept to commercialization. We’re pleased to take this natural next step in a partnership we believe strongly in.”

In 2024, Sage agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta, the parent company of Facebook. At the time, the companies reported that the project's first phase would aim to be operating in 2027.

The company also raised a $17 million Series A, led by Chesapeake Energy Corp., in 2024.

Houston expert discusses the clean energy founder's paradox

Guest Column

Everyone tells you to move fast and break things. In clean energy, moving fast without structural integrity means breaking the only planet we’ve got. This is the founder's paradox: you are building a company in an industry where the stakes are existential, the timelines are glacial, and the capital requires patience.

The myth of the lone genius in a garage doesn’t really apply here. Clean energy startups aren’t just fighting competitors. They are fighting physics, policy, and decades of existing infrastructure. This isn’t an app. You’re building something physical that has to work in the real world. It has to be cheaper, more reliable, and clearly better than fossil fuels. Being “green” alone isn’t enough. Scale is what matters.

Your biggest risks aren’t competitors. They’re interconnection delays, permitting timelines, supply chain fragility, and whether your first customer is willing to underwrite something that hasn’t been done before.

That reality creates a brutal filter. Successful founders in this space need deep technical knowledge and the ability to execute. You need to understand engineering, navigate regulation, and think in terms of markets and risk. You’re not just selling a product. You’re selling a future where your solution becomes the obvious choice. That means connecting short-term financial returns with long-term system change.

The capital is there, but it’s smarter and more demanding. Investors today have PhDs in electrochemistry and grid dynamics. They’ve been burned by promises of miracle materials that never left the lab. They don't fund visions; they fund pathways to impact that can scale and make financial sense. Your roadmap must show not just a brilliant invention, but a clear, believable plan to drive costs down over time.

Capital in this sector isn’t impressed by ambition alone. It wants evidence that risk is being retired in the right order — even if that means slower growth early.

Here’s the upside. The difficulty of clean energy is also its strength. If you succeed, your advantage isn’t just in software or branding. It’s in hardware, supply chains, approvals, and years of hard work that others can’t easily copy. Your real competitors aren’t other startups. They’re inertia and the existing system. Winning here isn’t zero-sum. When one solution scales, it helps the entire market grow.

So, to the founder in the lab, or running field tests at a remote site: your pace will feel slow. The validation cycles are long. But you are building in the physical world. When you succeed, you don’t have an exit. You have a foundation. You don't just have customers; you have converts. And the product you ship doesn't just generate revenue; it creates a legacy.

If your timelines feel uncomfortable compared to software, that’s because you’re operating inside a system designed to resist change. And let’s not forget you are building actual physical products that interact with a complex world. Times are tough. Don’t give up. We need you.

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."
