Two months ago, Bluecore Energy was a small team with a bold idea: put nuclear reactors on barges and float them wherever power is needed. This week, investors made clear they believe it.
The startup announced an oversubscribed $50 million seed round on Tuesday, layered on top of a $10 million pre-seed raised just months earlier. Silverton Partners led the round. It closed in eight weeks.
The Pitch: Power That Moves
Bluecore builds small modular reactors mounted on floating platforms instead of fixed plants. The idea is portability. A barge can be towed to a port, a data center, or a community that needs power fast, without years of permitting and construction tied to a single site.
Kofi Asante, the company’s founder, points to a track record that already exists.
“The Navy is doing this as we speak, for the last 70 years, and has never had an accident,” he said in an interview. “We just made it smaller, so you can actually move things around in a way that doesn’t take years, but days.”
Investors Kept Calling
Asante said he wasn’t planning to raise again this year. Then the calls started.
Several pre-seed backers doubled down, including Slauson & Co., Harlem Capital, and Ripple co-founder Chris Larsen. New investors joined too, among them Collab Capital, Kevin Hart’s HartBeat Ventures, and angel investors from Tesla, Uber, Amazon, and Google.
“I just kept having to figure out a way to make more room” on the cap table, Asante said. “I wasn’t anticipating us raising that level of capital in that period of time.”
Regulators Are Already Involved
Bluecore came out of stealth in July as the first nuclear company headquartered at a major U.S. port, the Port of Long Beach. It has since launched two floating barges.
The company is now working with the Department of Transportation’s Maritime Division, the U.S. Nuclear Regulatory Commission, and the U.S. Coast Guard. Formal reviews of its reactor design began in August, a step toward certifying the floating plant for use.
“We have been talking to them both since the inception of the company and design, but officially started the formal engagement in August,” Asante said.
What the Money Is For
The new capital will fund product development, regulatory work, nuclear fuel purchases, and hiring. Asante expects supply chain constraints, not technology, to be the biggest hurdle.
“Our team comes from SpaceX, Rivian, and Toyota, so we are applying similar strategies to be able to secure critical parts,” he said. Bluecore already has barges and a reactor, he added, and is preparing to order nuclear fuel through a partner at a national nuclear lab.
Interest is coming from multiple directions, Asante said, including ports, AI data centers, and communities in need of clean power and water.
The Bigger Bet
For Asante, the business case rests on a broader claim.
“My philosophy is that access to clean energy and also clean water should be a human right,” he said.
Whether floating reactors can scale into a real alternative to fixed nuclear plants remains untested. But for now, investors are betting the barge gets there first.
