The investor you haven't touched in six weeks. The decision that stalled two months ago. The customer relationship quietly cooling. You know it's all there — you just can't hold it all. Cossi holds it for you, notices what shifts, and prepares you for what's next. Private by architecture.
Free to start. Pro features from $9.99/mo.
Founders don't lose companies to competition. They lose them to context: the follow-up that never went out, the decision that stalled for a month, the investor who quietly cooled, the promise that slipped between meetings.
Cossi carries the context for you. It runs a loop — brief, prepare, act, remember, anticipate — quietly, every day, on your device. You keep the judgement. Cossi keeps the receipts.
Not another productivity app. Not another CRM. Cossi runs a five-step loop — brief, prepare, act, remember, anticipate — at CEO scale, on your phone, without a cloud. Here's the shape of it for founders.
Every open decision, every promise, every commitment — held in a live register that surfaces overdue items before they compound. Not a task list. The thing that actually breaks when a company scales.
Every founder I respect carries enormous context in their head. Cossi is the first tool that carries it with them — quietly, privately, and without asking.
