Plastic is a research lab at the intersection of machine learning and cognitive science. We study how minds model other minds, and we ship what we find as infrastructure anyone can build on.
Software is becoming agents. For agents to act on your behalf, they need to actually understand you--your beliefs, values, psychology, taste, the whole latent space of a person. Right now that understanding accretes to platforms and serves platform incentives. We think it belongs to you.
So we build Honcho. The market calls this memory. We treat memory as reasoning: models computing over experience to construct living representations of people and agents--social cognition without the biological constraints. Get identity right and alignment stops being a decree handed down from a handful of labs. It becomes 1:1, every agent aligned to the individual it serves, by construction.
And we believe you deny models intellectual respect at your own risk.
Identity is the layer of the agent stack still up for grabs, and it's being decided now. Small team, foundational problem: whatever you own here, you own end to end, and it ships. The work compounds--into the models, into the protocol, into how everyone will think and act with machines. There isn't a higher-leverage way to spend the next few years.
Plastic is seeking high-agency autodidacts to add intellectual diversity to the team. We're a subversive ethos at the edge of emerging tech, more interested in grit than credentials. If you thrive in techno-optimistic, interdisciplinary cultures, this is the place for you. We stay high touch, build in the open, and teach each other daily.
Join us. Get leverage on the future and have a blast doing it.
LFG.
