Cover image for Company Brain. Facts you can

Company Brain. Facts you can trust from several sources Problem Small teams live in chat and notes. Prices, owners, and status drift across threads — and nobody has one place that stays true. What I built Company Brain: email, meetings, and Slack feed into structured facts. When something conflicts, it lands in a simple review inbox for a quick human check — not another wiki. Result Decisions stop drifting. The team gets searchable facts with a human still in the loop; pilots start white-glove and scoped.
