Operating in consumer based in San Francisco, CA, USA, Nessie operates.
Profile
Knowledge work is being restructured by AI. Strategy happens in Claude. Research happens in ChatGPT. Building happens in Claude Code. The people defining the next decade of work are already thinking with AI every day. But none of that thinking compounds. Every session starts from zero. The reasoning behind decisions, the context behind strategies, the evolution of ideas across hundreds of conversations - all of it evaporates.
Nessie is the infrastructure that makes it permanent. We auto-sync AI conversations and agent traces across every major provider - ChatGPT, Claude, Gemini, Perplexity, Claude Code, OpenClaw, Codex, and more - and turn them into a context layer that is queryable, reusable, and shareable by you, your team, and your agents. No browser extension. No manual capture. Your thinking flows in automatically and compounds over time.
Where we are going: the AI-native organization runs thousands of agents that are powerful but amnesiac, and Nessie is the layer that integrates what the organization knows, what it has decided, and how its thinking has evolved. Science has journals, law has case law, software has git; AI-native knowledge work has had nothing. We are building it.
We are two Yale CS grads and former Amazon engineers. Backed by BoxGroup, Pioneer Fund, Y Combinator, Precursor, and more.
