Dutch cloud computing company, Nebius Group, has agreed to acquire Eigen AI for $643 million, valuing the 20-person MIT-alumni startup at roughly $32 million per employee. Eigen's infinclusion optimisation technology maximises tokens per Nvidia GPU, the most valuable capability in AI infrastructure. The acquisition strengthens Nebius’s Token Factory inference platform as the neocloud market expands rapidly. The company's ability to extract more value from each chip changes the unit economics of the entire business. The deal is Nebius's second acquisition in three months following its purchase of Tavily, an AI agent agent for $275 million.
