In this episode, Kingsley Maunder breaks down one of the most overlooked aspects of startup building: proper validation. With over two decades in the startup ecosystem, building products used by Disney, EA Sports, Snap, and more, Kingsley shares the hard-won lessons behind his framework, The SALT Test.
We explore how founders can turn raw ideas into validated products, avoid the assumption trap, distinguish noise from real traction, and leverage AI to accelerate product discovery. This conversation is a masterclass in thinking clearly, testing quickly, and building what people actually want.
