It's Monday morning. You walk in, grab your coffee, and look at the vivarium you helped build from scratch. Your vivarium. You check the board. First up: feed the mice. These are your mice - you set them up, you're responsible for everything that happens in this room.

A vendor calls. Shipment delayed on the IVC rack you urgently need. Two weeks ago, you would've accepted that. Not anymore. You've learned to find the bottleneck and solve it. Thirty minutes later, the shipment is back on track.

We're planning first-in-human safety in 2026 — which would be a world record for a non-vaccine therapeutic built from scratch. Our founding scienti...
