Core Features
ARR, headcount, runway, and milestones, extracted from board decks and founder updates and tracked over time.













Record. Knowledge. Intent.
Take the call, send the email, pass on the deal. Nothing to log afterward, because the record already reflects it.
Ask in the app, in Slack, over email, or through any agent via MCP. You don't go to the system.
Every answer is built from every email, meeting, and document the firm has touched, not from the last field someone remembered to update.
How it works
Connect your email and calendar; agents extract, structure, and keep the record current.
Connect your email and calendar. No migration, no data entry.
Agents read the work already happening and structure people, companies, deals, and updates.
You confirm the edge cases. Kosa learns your firm's conventions.
Kosa keeps the firm's record current, answers anything, and reaches out before you ask. Connect your email and it's current within an hour.
