Organization Transport Protocol

Right now, every company running AI agents is figuring it out alone. But zoom out. We're heading toward a world where every person has their own AI, the same way everyone has their own phone. When that happens, how does your AI learn from what mine figured out? How do you transfer operational intelligence between AI systems without blind trust, without contamination, without losing where it came from? That's the problem we built OTP to solve.
