Company Overview
Aetherflux is an American aerospace and renewable energy company developing a space-based solar power system. Founded in 2024 by Robinhood co-founder Baiju Bhatt, the company's mission is to deliver reliable and affordable energy to Earth. Aetherflux plans to build a constellation of small satellites in low-Earth orbit that collect solar energy, convert it to electricity, and transmit it to ground stations via infrared lasers. This approach is intended to provide power for various applications, including military operations, disaster relief, remote research stations, and eventually households and businesses. The company raised a $50 million Series A round in April 2025, bringing its total funding to $60 million, with backers including Index Ventures, Breakthrough Energy Ventures, and Andreessen Horowitz. Aetherflux is planning its first space demonstration mission for early 2026.
