Mijnwater starts drilling for new heat source on Terhoevenderweg in Heerlen New source expands Parkstad’s district heating and cooling network Mijnwater has started drilling work for a new heat source at Terhoevenderweg in Heerlen, marking another important step in the expansion of its sustainable heating and cooling network in Parkstad. After a period of preparation, work began this week and is expected to continue for three to four weeks. Because the operation must be completed safely and efficiently, the drilling is taking place 24 hours a day, seven days a week. The project is part of Mijnwater’s broader effort to strengthen a low-carbon energy system for the region. The new source will tap warm groundwater in a former mine passage deep underground and feed that energy into the company’s network. For Heerlen and the surrounding area, this means further development of a district energy system that draws value from the region’s mining past while supporting a more sustainable energy ...
Inside a Geothermal Startup’s Mind: Strategy, Funding, Ethics, and the Brutal Race to Commercialize
Not the quiet of peace, but the quiet of pressure.
It’s the silence of teams racing to commercialize before competitors arrive. The silence of founders balancing mission and survival. The silence of a clean energy industry that desperately needs success stories… but is still learning how to measure them.
In this one-on-one interview, we explore what it really takes to build a geothermal-driven clean energy company in today’s market, from strategic decisions and funding discipline to leadership, ethics, and the painful sacrifices behind growth.
1) Vision & Strategy: “Speed Is Everything”
Q: Teverra has grown rapidly, but competitors are always emerging. What is the single most critical strategic decision that could either make or break Teverra in the next five years?
A: If I had to reduce everything to one make-or-break strategic decision, it would be “Whether Teverra becomes an product company (with scalable, defensible platforms) or remains primarily a project-driven consulting company. That single choice cascades into almost every outcome over the next five years. Also, we have multiple technologies approaching market readiness, and the next five years will depend on how quickly we can turn prototypes into commercial products and capture market share before others do.
That single answer carries a heavy truth: in clean energy innovation, being right is not enough , you must also be early enough.
Q: Many startups claim to “disrupt” industries, but very few truly do. How Teverra distinguish itself from better-funded and more established competitors?
A: We distinguish ourselves through two things: deep subsurface expertise and solving validated industry problems. We’ve transferred oil and gas subsurface knowledge into clean energy, geothermal, CCS, and energy storage spaces. We don’t build technology just because it’s interesting. We build solutions for problems the industry confirms are real. Furthermore, Teverra lives at the physics–data boundary while most competitors sit on only one side. We focus on de-risking outcomes, not selling tools.
This is not disruption by noise. It’s disruption by precision.
Q: Looking back, is there any major strategic decision you would reverse if you had the chance?
A: Yes. As a technical founder, I would have brought in a business-oriented partner much earlier. I believe that would have accelerated our growth significantly.
2) Funding: Growing Without the “Investor Lie” Trap
Q: Startups often overpromise and underdeliver. Have you ever misled investors, intentionally or unintentionally, about growth projections?
A: While this is not our culture, our growth model helped us avoid that. We’ve been self-funded through consulting revenue and supported through non-dilutive grants like DOE and NSF. Without investor pressure early on, we didn’t face the temptation to inflate projections.
This is one of the most underrated advantages in startups: when your runway isn’t built on hype, your decisions become sharper
Q: How do you justify valuation to investors, especially if profitability is not yet fully proven?
A: Valuation is driven not by near-term profitability, but by de-risked future cash flows and strategic scarcity. The real value lies in our portfolio and progress. We’ve developed seven technologies in parallel, so we’re not dependent on any single solution. As these technologies reach market readiness, we’re spinning out subsidiaries focused on specific technology sets, enabling us to attract targeted investment and accelerate commercialization.
A diversified pipeline becomes a shield not every bet has to win for the company to survive.
Q: What’s the harshest financial lesson you’ve learned as a founder?
A: Raising large rounds too early,before product-market fit is established,can significantly dilute founders and misalign incentives. By prioritizing bootstrapping and non-dilutive funding, we preserved ownership, maintained strategic control, and built our technologies with discipline before scaling. Remember,
3) Leadership & Culture: Building Without Poisoning the Team
Q: Founders often talk about strong company culture. How do you deal with toxic behavior or underperforming employees without derailing morale?
A: We protect our culture by acting early and avoiding reactive interventions later. This starts with disciplined hiring, where we prioritize passion, alignment, and shared values. This approach has enabled us to build a strong, cohesive team and minimize internal friction over time. Even as a remote-first organization, we have maintained high levels of collaboration and cultural cohesion.
The message is clear: culture is not fixed later, it is selected early.
Q: In moments of crisis, do you make decisions based on instinct, data, or consensus?
A: In a crisis, I start with instinct informed by experience to set direction, use data to validate and refine the decision, and then build alignment to execute. Speed comes from instinct, accuracy from data, and impact from team alignment.
Q: Have you ever had to fire a co-founder or key executive?
A: There have been limited instances where alignment or performance no longer matched the company’s needs; however, overall, we’ve maintained strong internal alignment, which has helped us avoid major leadership disruptions.
4) Ethics: The Clean Energy Industry Runs on Credibility
Q: Have you faced situations where short-term gain conflicted with long-term values?
A: Yes. In the early stages of our journey, when near-term revenue was especially important, we encountered opportunities that offered quick financial returns but risked diverting us from our core mission or weakening our long-term strategy. We chose to decline those opportunities. These experiences helped sharpen our strategic discipline, and today, with a clearly defined vision and mission, we remain highly focused on long-term value creation while avoiding distractions from short-term gains.
Q: What’s the most morally ambiguous decision you’ve had to make as a founder?
A: The most difficult and morally complex decision I’ve had to make was reducing headcount during financial hardship, even when people were doing great work. It meant choosing between individual livelihoods and the survival of the company. There’s no easy version of that decision,but acting decisively and transparently was necessary to protect the mission and the team as a whole.
Q: If a major client offered a deal that could significantly boost revenue but compromise values or mission, would you take it?
A: No. We are mission-driven around accelerating clean energy using subsurface expertise. We’ve learned that short-term revenue is never worth compromising our values or long-term mission. If an opportunity doesn’t align with our strategy or would dilute our focus, we walk away. Sustainable growth comes from staying true to our core purpose, not from chasing quick wins.
5) Market Reality: The Industry Still Lacks Benchmarks
Q: Many startups fail because they misread the market. What is your biggest blind spot in geothermal today?
A: A key blind spot today is the lack of standardized performance metrics for next-generation geothermal approaches such as EGS and closed-loop systems. Investors are looking for clear benchmarks,like cost per kilowatt,but these metrics are still emerging. This creates added uncertainty for both startups and investors as the market continues to mature.
This is one of the most powerful insights from the interview:
Geothermal isn’t just fighting geology, it’s fighting uncertainty.
Q: How do you respond to critics who say your solutions won’t scale or aren’t viable long term?
A. To make the answer short, we respond by focusing on execution, not debate. Scaling isn’t proven through slide decks,it’s proven through deployments, data, and repeatability. We’ve validated our technologies in real-world projects across different subsurface spaces, and we continue to move from pilots to operational use. Long-term viability comes from de-risking physics, demonstrating measurable outcomes, and building platforms that can be replicated across sites. Skepticism is natural in emerging markets; our response is to keep delivering results.
Q: If a global competitor entered your market tomorrow with ten times your resources, how would your company survive?
A: Large competitors bring capital and scale, but they also bring inertia. Our advantage is speed, deep subsurface expertise, and tightly integrated physics-plus-data platforms. We survive by staying close to real projects, protecting our IP, productizing what we’ve already de-risked, and moving faster from field validation to deployment. Big players can copy features; it’s much harder to replicate our domain depth, datasets, and execution velocity. Also, I believe the market is large enough that collaboration can expand the opportunity rather than shrink it.
6) Personal Resilience: The Price of the Mission
Q: Running a startup is emotionally taxing. Have you ever considered quitting?
A: Like most founders, there have been difficult moments, financial pressure, long sales cycles, and hard people decisions,that make you pause. But I’ve never questioned the purpose behind what we’re building. Each challenge reinforced the importance of work and strengthened my resolve to keep going. Passion is essential, when you truly believe in what you’re building, quitting is never an option.
Q: What’s the hardest personal sacrifice you’ve made, and was it worth it?
A: The hardest sacrifice has been time, especially with family and personal life. Building a deep-tech company demands long hours, constant travel, and mental bandwidth that never truly switches off. It hasn’t been easy, but seeing the impact of our work and the team we’ve built makes it worth it.
Q: In retrospect, what is the one decision you regret the most?
A: In retrospect, I wish I had invested earlier in formal education around business and finance. Coming from a technical background, I initially learned those areas on the job, which works, but it’s slower and more costly. Gaining that foundation sooner would have helped me make sharper strategic and financial decisions earlier in the company’s journey.
Q: Last words, recommendation etc for successful integration of geothermal in the energy mix:
A. If geothermal is to scale globally, it won’t happen through technology alone. It will require disciplined execution, transparent leadership, and real success stories that build public trust and attract meaningful capital.
I strongly believe the industry benefits more from collaboration than from competing narratives. When companies publicly criticize alternative approaches, it creates confusion among stakeholders and discourages investment, ultimately harming the entire ecosystem.
The credibility of the geothermal sector depends on delivering tangible results. If too many startups fail, confidence in the broader industry is at risk. That’s why we focus on validated problem-solving, strong technical foundations, and collaboration. Success is not just important for individual companies; it’s essential for the future of geothermal as a whole.
This is a geothermal truth many avoid saying:
a single loud failure can damage an entire sector’s funding mood. We are all sitting in the same boat.
Closing Thoughts: Why This Interview Matters
This interview reveals a side of geothermal entrepreneurship that most press releases never show:
Commercialization is the true battleground.
Funding can be a weapon, or a trap.
Ethics and credibility are not optional in clean energy.
And the personal cost behind “innovation” is very real.
