Most side projects don't fail because the developer isn't good enough. They fail because there's no structure, no real deadline, and nobody watching when you skip Day 4.

MVP Builder is a structured 13, 21 or 30-day sprint for developers with a full-time job whose side project is stuck. Not a course. Not a tool. Every evening you get one prompt for the next day, calibrated to your own project context — and at each milestone a human reads what you actually delivered before the sprint continues.

How it works: it starts with a five-question quiz and ends in a free 30-minute call, not a signup form. The call settles which module fits (Bronze 13 days, Silver 21, Gold 30) and what your sprint goal is. That goal is written down before day one and frozen — you are measured against the wording from that day, not against what it became.

Milestone days are mandatory: Bronze on day 13, Silver on 13 and 21, Gold on 13, 21 and 30. On those days you attach a URL or a file — a screenshot showing recognizable progress, a live demo, a repository with real commits, or a short walkthrough video. Text alone is not enough, and an empty repo or a wireframe without working code doesn't count. The ordinary days in between are not mandatory. The milestones are.

Miss one and the sprint pauses rather than quietly continuing. There is a fixed grace period; if it lapses, the sprint is suspended and the only way back is a request we decide on.

What it costs in time: three to five hours a week, spread across several days rather than taken in one block. Below three hours a week is a reason we say no.

The first 7 days cost nothing. You leave a card at checkout and nothing is charged before day 8, so the week that decides it is behind you before any money moves.

Acceptance is manual and happens in that call, not in a form. Vague scope gets turned down there.
