Decart raises $300M Series B at $4B — Nvidia joins the world-models bet
Read this because Decart's pitch is the full stack: inference-optimization software (DOS) under real-time world models (Lucy, Oasis). The bet isn't the $4B valuation — it's that the team selling 8x token throughput also builds the world model that needs it. Vertical integration as moat.
Israeli AI startup Decart raised $300M Series B at $4B (May 18), led by Radical Ventures, Nvidia participating. DOS stack hits 1,600 tokens/sec — 8x average.
