Building is expensive. Deciding what to build is not.

Most first products fail for an unglamorous reason: nobody checked whether the problem was real, who actually had it, or what those people already do instead. The work that answers those questions is scattered across documents, notes, spreadsheets and chats, so it rarely gets done properly.

Cepheus puts that work in one place. You start with a problem, talk to real people, keep what they said as evidence, map what already exists in the market, and watch what you know separate from what you are still assuming.

The product is deliberately honest about the difference. Evidence is what you observed. An assumption is what you believe. A question is what you still cannot answer. An insight is what the evidence may be telling you. Cepheus never quietly promotes one into another, and it never invents a customer, a quote or a market fact.

AI is here to remove research labour — reading back your own interviews, spotting repeats, drafting a brief from what you gathered. It runs when you ask it to, on your material. The decision stays yours.

Phase 1 supports founders starting from an idea: Explore, Customer Discovery, Market Landscape, Solution and a build brief. Already-building and company-stage workflows come later, and we would rather say so than fake them.
