The constraint the current investment wave cannot purchase is throughput in wet-lab validation. AI platforms like Boltz-2 [5] and MIT's generative model [2] have substantially compressed the design phase, but every generated candidate still requires experimental confirmation that no amount of compute replaces. as generation outpaces screening — the consequence being that the most sophisticated design tools in the field's history are now producing queues, not cures. Excelsior's raise and the broader are bets on platform infrastructure…
