Inertia Enterprises is building a next-generation inertial-confinement fusion system that uses arrays of high-energy lasers to compress fuel pellets until they fuse and release energy. The technology is derived from the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, the only site to have achieved scientific breakeven in controlled fusion. Inertia aims to commercialize this approach by engineering lasers capable of delivering 10 kilojoules ten times per second and by mass-producing 4.5 mm fuel targets for under $1 each. Each planned power plant would deploy around 1,000 of these lasers, a significant scale-up from NIF’s 192-beam system, with the goal of reducing costs and boosting energy output. The company’s co-founders include Twilio co-founder Jeff Lawson, NIF experimental lead Annie Kircher, and Stanford professor Mike Dunne. Inertia intends to begin construction of its first grid-scale fusion power plant in 2030. The startup has secured substantial early funding, positioning it among the most well-capitalized private fusion ventures to date.

Ricursive Intelligence is creating an artificial intelligence system capable of designing and continuously refining AI chips, including generating its own silicon substrate layer to accelerate performance gains. The company’s approach builds on AlphaChip, a reinforcement-learning–based chip-layout technique that its founders previously deployed across four generations of Google’s TPU processors. By repeatedly optimizing designs, Ricursive believes its technology can drastically shorten chip-development cycles on the path toward artificial general intelligence. Founded by former Google researchers CEO Anna Goldie and CTO Azalia Mirhoseini, the startup formally launched only two months ago. Since launch, it has secured $335 million in funding and now carries a $4 billion valuation. Key backers include Lightspeed, Sequoia, DST Global, Nvidia’s NVentures, Felicis Ventures, 49 Palms Ventures, and Radical AI. Ricursive plans to apply its capital toward product development and scaling its AI-driven chip-design platform.
