Every generational platform — the printing press, the PC, the internet — has been judged in the end by a single question: what can a person now do that they could not do before? We believe AI agents are the most consequential answer to that question in a generation.
Frontier models have crossed into commodity territory. The performance alpha has moved up the stack, to the harness, context, and memory layer — the scaffolding where a capable model becomes a collaborator that remembers what you care about, understands the problem in front of you, and extends your reach.
The result is emergent: a researcher who can read an entire field in an afternoon, a founder who can prototype what used to take a team, a clinician who can think alongside the literature, a student who has the patience of a tutor at 2 a.m. Agents are not replacements. They are amplifiers — and the applications we can barely imagine today will rest on the infrastructure being built now.
Priors Capital represents that thesis. We write first checks to the founders building the layer that makes this human.
Runtimes, tools, and orchestration that turn a capable model into a dependable collaborator — one a person can actually trust with work that matters.
Retrieval and grounding that give agents the right knowledge at the right moment — so people can work at the edge of their curiosity instead of the limits of their memory.
Long-horizon state, evaluation, and observability. Memory is how an agent comes to understand you — your projects, your taste, your standards — and how trust is earned over time.
We write first checks between $500k and $2M, lead or co-lead, and concentrate. Fund I is $80M across roughly twenty-five companies at the agentic infrastructure layer. We do not index, and we do not hedge.
We back founders who are building tools we would want to use ourselves — the kind that quietly raise the ceiling on what one person, or one small team, can accomplish. Be early, be opinionated, be useful.
