A 19-year-old founder (Dhravya Shah) pivoted a viral open-source "second brain" app into a B2B memory infrastructure API, and the page claims ~$29M total funding, anchored on a much smaller $2.6–3M seed round from October 2025. Susa Ventures led, with angels including Jeff Dean, Dane Knecht, and David Cramer. The technical pitch: a universal memory API that extracts insights from unstructured multimodal data (PDFs, video, email), builds dynamic knowledge graphs rather than keyword-matching RAG, and returns relevant context in milliseconds. They built their own vector database and extraction pipelines instead of using off-the-shelf parts. Named customers include Cluely, Montra, and Scira, plus a robotics collaboration. The aggregate $29M figure is the part to squint at — the individual round reports all say ~$3M, and the source's own references only corroborate the $2.6–3M. The rest is aggregation with no breakdown. Standard "seed round plus vibes equals Series A math." Worth noting the actual engineering question: low-latency memory retrieval across sessions is a real unsolved layer, and competitors (Mem0, Letta) are already shipping. The differentiation claim rests entirely on speed, per Joshua Browder.
