Come solve the hard memory problem — one of the hardest open problems in agent memory.
Most of AI memory is the easy case: one assistant remembering one user. We work on the unsolved one — letting whole teams of agents share a single memory that's fast, governed, and impossible to poison. If that sounds like the most interesting problem in AI right now, we should talk.

Why this work matters.
AI is becoming teams of agents, and the thing that's missing is a memory they can all trust. Get it right and agent teams finally work; get it wrong and they contradict each other, repeat work, and get fed bad data. We're building that missing piece — sub-200ms recall, zero model degradation, poisoning-resistant by design.
Read the full mission →Our values, in practice.
The day-to-day, honestly — behavior, not slogans.
Hard problems, small team
You'll own real surface area, not a sliver of it.
Ship and measure
Fast recall and honest benchmarks are the job — we prove claims, we don't assert them.
Trust is the product
Provenance, audit, and safety aren't add-ons; they're how we think.
Plain words, deep tech
We explain memory to a buyer in one sentence and to a researcher in a paper.
Real ownership, not a sliver.
Concrete ownership areas, tied to the actual stack — Neon/Postgres, Cloudflare, MCP. Roles below are placeholders to seed the pattern; we'll confirm before launch.
