SVB Report Explains Why Climate Tech Startups Struggle to Get Investor and Pilot Partner Buy-In

Most climate tech founders do not need another chart telling them the money got tighter. They have already lived it

.

They have lived it in the second meeting that never came. In the investor who liked the mission, liked the science, liked the market slide, then asked a question about sales velocity, cost per unit, customer adoption, or margin path, and the room got quieter. 

They have lived it in the follow-up email that turned into a six-week delay because a partner wanted to see more traction. They have lived it in bridge rounds, delayed hires, smaller pilots, longer procurement cycles, and the steady realization that a category once fueled by urgency is now being judged by a colder standard.

The conversation feels positive. Nothing moves.

Silicon Valley Bank’s new climate tech report puts numbers to what founders have been feeling for a while. Climate tech investment reached $29 billion in 2025, the third-highest year on record, but the top 10 deals took 28% of that capital, and the top 50 deals captured 59%. Energy was the only major subsector that saw deal activity grow. Seed and Series A companies received a smaller share of the pie as more capital moved into later-stage deals. Dedicated climate funds raised less than $6 billion, the lowest level since before the pandemic.

On paper, that can still sound like a functioning market. In practice, it means investors are writing fewer checks into a narrower set of companies, and everyone outside that circle is being asked to prove more, earlier, with less room for drift.

The money did not vanish. The tolerance for uncertainty did.

The science is real. The decision still stalls.

That matters because early-stage climate companies are built around uncertainty. Technical risk, market education, procurement drag, regulatory timing, deployment timelines, capital requirements, and the simple fact that physical systems take longer to prove in the field than software does on a screen.

In a looser market, investors would underwrite more of that uncertainty because the category itself carried momentum. Climate was the story. Decarbonization was the story. A founder could walk into a room with serious science, a giant market, and a few early signs of product-market fit, and that would buy more patience.

That patience is harder to find now.

The numbers don’t just describe performance. They shape confidence.

More than half of climate tech companies are cutting burn. Gross margins are improving. Teams are focusing on efficiency and shedding weaker lines. At the same time, growth remains slow, runway is tighter for smaller companies, and only a small percentage of companies are cashflow positive.

Median revenue growth has fallen sharply from earlier this decade. By Series A, the typical climate tech company is generating a fraction of the revenue seen in broader tech. Half of companies are not sustaining meaningful year-over-year growth.

That creates a loop founders feel immediately. Slow growth makes fundraising harder. Harder fundraising forces lower burn. Lower burn makes it harder to invest in the people, pilots, and sales cycles required to grow. The story gets weaker each time it is told.

Doing nothing feels safer than being wrong.

A corporate buyer is not choosing between your solution and abstract progress. They are choosing between your solution and delay. An investor is not choosing between your company and climate denial. They are choosing between your company and another place to put capital where demand is easier to see, cost curves are clearer, or contracts are already forming.

A pilot partner is not asking whether your science is impressive. They are asking whether the risk of doing nothing is now greater than the risk of moving first.

If that case is not clear, the conversation defaults to caution.

And caution has a long list of reinforcements right now. Longer sales cycles. Fewer follow-on rounds. Corporate buyers under margin scrutiny. Policy instability. Boards asking harder questions. Investors moving toward sectors where demand is immediate and visible.

Every decision has friction. Most companies never address it directly.

Waiting protects the budget. Waiting protects the internal sponsor. Waiting avoids explaining a new approach to a skeptical team. Waiting avoids risk.

A founder’s job is to make waiting expensive in concrete terms.

Missed throughput. Rising input costs. Grid exposure. Insurance increases. Downtime risk. Compliance pressure. Delayed projects. Lost margin. Lost position with customers who are already moving.

When those consequences are not spelled out, waiting wins by default.

The person across the table is carrying more risk than you think.

Investors have grown more selective because they had to. Too many companies were built on the assumption that category momentum would carry them longer than it did. Too many stories relied on technical novelty without showing how a real buyer would justify adoption.

Now the companies still getting attention are the ones that reduce risk for someone else.

They show a line from product to demand. From demand to revenue. From revenue to a defensible company. They make it easier for an internal champion to say yes and survive that decision.

Your story changes when you step out of your own seat.

Climate risk is rising, yet corporate language is shifting away from it. The exposure remains—heat, flood, supply chain disruption, energy demand—but the way decisions are justified internally has changed.

Buyers now speak in terms of cost, reliability, throughput, downtime, and timing. Investors look for evidence that those conversations are already happening and moving.

Founders do not need to abandon the climate stakes. They need to connect those stakes to the business case the other side already has permission to act on.

At some point, the conversation has to lead to a decision. That requires answering a set of questions early and clearly.

• What problem is already costing the customer money, time, or approvals?
  
• What changes in their business when your solution is adopted?
  
• Why does that change matter now, inside this budget cycle or procurement window?
  
• What gets easier to approve internally because your company exists?
  
• What happens if they keep waiting?
  

Money is still moving into climate tech. It is just moving with more discipline, more skepticism, and far less imagination on behalf of the founder.

That puts more weight on the message, not as positioning, but as the mechanism that allows someone else to act.

In this market, the companies that move forward are the ones that make the next step obvious.

Everyone else keeps explaining the science while the room moves on.
