Three Most Interesting Deals

Decart ($300M from Radical Ventures): Decart turns live video into interactive, immersive digital environments using AI models that can reinterpret footage on the fly. That puts it squarely in the path of two fast-moving tailwinds: real-time generative media and the demand for “game-engine-like” experiences without bespoke 3D production. What’s notable is the product direction—live transformation rather than offline VFX—which opens doors in entertainment, advertising, and creator tools where latency and controllability matter. The $300M Series B at a $4.0B valuation, led by Radical Ventures, suggests the company is scaling beyond demos toward a platform developers can actually build on.

Thea Energy ($100M from US Innovative Technology Fund): Thea Energy is developing a fusion power system designed to be cheaper to build and easier to scale, aiming for zero-emission electricity without the intermittency of renewables. Fusion funding is shifting from “physics experiments” to “power-plant engineering,” and Thea’s pitch sits on that boundary: practical hardware choices, manufacturability, and a path to repeatable deployment. Located in the New Jersey industrial corridor, it’s positioned to recruit fusion and high-end manufacturing talent and to prototype with real supply-chain proximity. The company’s $100M Series B led by the US Innovative Technology Fund gives it meaningful capital to push from concept to integrated subsystem milestones—where fusion companies start to separate from the pack.

Isomorphic Labs ($2.1B from Thrive Capital): Isomorphic Labs is building IsoDDE, a unified AI stack to design drugs across therapeutic areas and modalities—from structure prediction through candidate selection—rooted in DeepMind’s AlphaFold work but aimed at full discovery workflows, not benchmark wins alone. Momentum shows up in named pharma partnerships (Novartis, Lilly, Johnson & Johnson), a mix of partnered and wholly owned programs, and the company’s push to move internal assets toward the clinic. With teams in London, Cambridge, MA, and Lausanne, it is scaling hiring across AI, engineering, medicinal chemistry, and clinical after the round. Thrive Capital led the $2.1B Series B, with Alphabet, GV, Temasek, CapitalG, MGX, and the UK Sovereign AI Fund in the syndicate—unusual depth of capital for a company founded in 2021.
