Startup validation is the process of testing whether a venture idea has real customers, demand, and a path to revenue before heavy investment in building.
A founder interviews ICP users, maps substitutes, and sells a concierge pilot before writing a full app.
Building is cheaper than ever; wasted months on the wrong problem is still expensive. Validation reduces that risk.
Use the ValidateIdea 7-Step Validation Framework: customer → problem → demand → competition → willingness to pay → experiment → decide.
