Non-dilutive Climate & Energy accelerators
These climate programs fund founders without taking equity: government lab fellowships that pay a salary for full-time work, state-backed programs with cash grants, and corporate-backed awards. Read the fine print on each one, because non-dilutive money usually comes with real commitments instead: relocation, citizenship requirements, multi-year timelines, or entry by nomination only. Amounts are listed where the program publishes them.
