The most expensive mistake in software is six months and $40k spent building something nobody uses.
It usually starts with a feature list: fourteen items, each one reasonable, each one based on what the founder believes the market wants.
The list gets built exactly as written, launch day comes and the dashboard stays empty.
By the time the assumptions are proven wrong, the runway is gone and there’s nothing left to pivot with.
A founder recently came to us with that exact list: fourteen features, all marked “needed for launch”.
We didn’t start coding, we spent discovery arguing with the list, feature by feature, assumption by assumption, until we agreed on three.
Building what’s on the list is the easy part, the harder job is telling a founder which parts of the list are fiction before they pay for them.
If you’re drafting a feature list right now, get a second opinion before you lock it in.
