Founders do not need a 12-month discovery phase. They need a marketplace they can put in front of buyers and sellers, with the core loop working: list, match, transact, and get paid.
We run an 8-week build. Week one locks the scope: roles, listings, payments, and the admin surface. The rest of the weeks ship in public milestones — not a big-bang demo at the end. That is how a pre-seed team can raise, onboard supply, and start charging without waiting on a rewrite.
What stays out of v1 is just as important. Fancy recommendation engines, multi-currency tax engines, and five extra user types wait until the marketplace has real volume. We build the path that can take those later without a throwaway MVP.
