Public story · 2026-03-21 · source-backed
Hindsight by Vectorize.io builds a knowledge graph from agent interactions rather than storing raw text, modeling how human long-term memory works. 91% on LongMemEval (state-of-the-art). The MCP server makes it a drop-in memory backend for Claude, Cursor, and Windsurf via a single JSON config change. Boulder startup, $3.6M seed from True Ventures.
