Raising a Series A in climate and energy.
At Series A, climate and energy investors move from "does it work" to "will someone pay for it at scale". Expect deep technical diligence and questions about your first commercial deployment.
Climate / Energy
Climate and energy investors judge three things before anything else: proof the technology works outside the lab, a cost path that beats the incumbent, and a plan to pay for real-world deployments without burning venture equity on steel and concrete.
What Series A investors expect in climate and energy
The questions become engineering and commercial at once. Expect diligence on each of these.
Pilots that turned commercial
- At least one pilot converted into a paid contract
- Buyers asking for the next, larger deployment
- Letters of intent for offtake or repeat orders
Technology that survives diligence
- Operating hours and uptime from the field
- Outside engineers able to check your claims
- A design frozen enough to build the next unit
A financing path for deployment
- What the first commercial unit or plant will cost
- Which part equity funds and which part debt could fund
- A team member who understands project finance

Questions founders ask
When is a climate company ready for Series A?
When pilots show the technology works in the field and buyers want more of it. Investors want operating data over time, not a single good test.
Should an energy company's venture arm lead my Series A?
Sometimes it makes sense, but most strategics prefer to follow a financial lead. Think about whether their stake could put off other buyers or partners.
