As an accountant himself, Gavin saw a problem to be solved and jumped at the opportunity, hiring an agency to begin developing it. Within weeks he realised he was burning cash, with no confidence he was building the right thing. Fast-forward and Gavin is taking a structured approach to product-market fit, building his tech alongside future users - testing himself and his assumptions every step of the way. Gavin manages to remain confident, yet humble, an important combination for any founder.
