Hakutaku

Hakutaku addresses a specific and familiar organisational bottleneck: the things that matter most live in the heads of two or three people, usually the founder's, so the team asks questions all day and nothing moves until that person replies. Hakutaku's answer is to build a clone of that judgment — one that learns how the person decides and answers the team in their place, so the founder remains the founder but stops being the bottleneck.

The mechanism has four parts. Ingestion pulls in meetings, documents and the tools the company already runs, with a Transcript feature recording and transcribing meetings. An ontology converts messy material into named entities — people, clients, projects, decisions and rules — explicitly including decisions that were rejected. A knowledge graph then holds the most recent decision on every subject along with what it replaced. Finally a harness of agents, which Hakutaku calls yokais, consults the graph before responding, and also learns from how the team uses it and from the agents the team builds. Those agents surface in Hakutaku's own chat, in its Agent Builder, and inside Claude or ChatGPT via MCP.

The product is deliberately positioned as a decision layer rather than a generic assistant: the site states plainly that it is not a chatbot, not a RAG wrapper and not AI consulting with slides. Hakutaku is based in São Paulo, Brazil, publishes its plan at R$200 per month, and routes companies needing bespoke integration, a dedicated agent or on-premises deployment to a conversation with the team. Access is currently through a closed beta and a three-minute pre-assessment with a waitlist.
