Technical founders must prioritize understanding user insights to drive product improvement, avoiding the pitfall of merely focusing on feature development. Continuous engagement with users is crucial for comprehending retention and abandonment reasons. The transition to scaling occurs post product-market fit, where engineering plans should be executed to accommodate growth and demand. It’s essential to embrace the challenges of scaling, such as tech failure due to demand, and use this as an opportunity to identify and refactor necessary technical components. This phase also involves defining engineering culture and expanding the hiring process to accommodate a growing team.
