Apollo Atomics raises $31m: Evertrace spotted Assil Halimi 341 days earlier

Apollo Atomics has raised $31m in seed funding. The company is developing compact nuclear reactors designed for factory production.

Evertrace spotted Assil Halimi, co-founder of Apollo Atomics, 341 days before the funding announcement.

Before the round

On 13 September 2025, Evertrace spotted the first signal of company formation for co-founder Assil Halimi. The signal showed the company taking shape 341 days before its funding announcement.

What they’re building

Apollo Atomics is developing a nuclear platform based on pressurized water reactor technology. The company aims to make more of the plant a repeatable manufactured product, rather than treating every installation as a separate megaproject.

The MIT spinout was founded by Assil Halimi and Drew Walker. Its work is moving through demonstration, reliability testing and regulatory development.

Apollo announced $31 million in seed financing led by FCVC. Y Combinator, Telesoft Partners, Alumni Ventures and other investors participated. The funding supports demonstration facilities, manufacturing capacity, engineering and work with the U.S. Nuclear Regulatory Commission.
