What Astro does

Astro finds and buys land for new renewable energy projects, secures grid connections at minimal cost, and sells these development-ready projects to larger energy companies. Founded by Alex Fuster, a former Citadel energy trader, Astro's AI models identify profitable grid connections that eliminate the surprise costs causing 80-90% of renewable projects to fail. With the U.S. needing 2,000 gigawatts of new power generation by 2035 for AI data centers and electrification, Astro unlocks development opportunities that traditional methods consistently miss.

Describe what your company does in 50 characters or less.

The world's first AI energy developer

What is your company going to make? Please describe your product and what it does or will do.

We built an AI system that finds and acquires land for renewable energy projects, identifies low-cost grid connections, and packages these projects ready to sell to large energy companies. Our models spot profitable grid connection opportunities that avoid surprise costs responsible for most project failures.

Where do you live now, and where would the company be based after YC?

We're based in New York City, and will continue to be based here after YC.

Explain your decision regarding location.

New York is where Alex lives and knows the energy markets best from his background as a Citadel energy trader. Being close to energy companies and investors here matters.
