The Technical Gap in Early-Stage Startups
Most early-stage founding teams are strong on vision and sales, but lack hands-on technical leadership in the early phase. Transitioning from a first prototype to production software with real customers can be another pain point without technical expertise. Wrong technology choices, brittle architectures, and costly freelancer mis-hires compound quickly and are hard to reverse once a product has traction.
