The biggest mistake I keep seeing is founders choosing platforms based on trends instead of what the product actually needs.
A lot of products honestly do not need heavy architecture early on. People spend weeks debating stacks before even validating the idea.
But at the same time, I agree with the point that bad early decisions around data flow and UI structure become painful later. Especially once dashboards, permissions, workflows, and larger datasets start growing.
The hard part is balancing:
speed early on without creating a complete mess later
That’s probably why more founders are looking for guidance around architecture and MVP planning now instead of just hiring random developers. Seen platforms like foundersbar leaning into that space a bit by helping founders think through product direction and technical decisions earlier.
