Most side projects die not from bad ideas — but from the gap between "almost done" and actually shipped.You know the project. You have the repo, the domain, the Notion doc, maybe a half-written README. You built it on a weekend six months ago, and then — life happened. You opened it last Tuesday and closed it again. Not because you don't want to finish it. Because there was no deadline, no structure, and no one watching.This is not a motivation problem. This is a structure problem.MVP Builder is the structured 30-day sprint for full-time developers who want to ship a side project this month — not someday.Every day you get a focused daily prompt tailored to your specific project, your skill level, and exactly where you're stuck. Not generic productivity advice. Not a task board you'll abandon by Day 3. A daily written prompt that knows what you're building, where you left off, and what's actually blocking you.---### How it worksYou apply. Five questions, five minutes. What are you building, where are you in the process, what's your stack or toolset. The founder reviews every application — not an algorithm. Accepted within 48 hours or rejected with a reason.Your sprint starts. Every morning you get a daily prompt — generated by AI (Claude Haiku) and tuned to your sprint goal, tech stack, and your last check-in. Not a generic "work on your project today." Something like: "You said your Make workflow miscalculates edge cases. Before anything else today: reproduce the bug with a known input and write down exactly what the output should be. 20 minutes. Then we'll talk about fixing it."You check in. You write what you built, what blocked you, what you shipped. Short is fine. Honest is required.A human reads it. The founder reads your check-ins. Not skims — reads. If you go quiet two days in a row, you get a different prompt: not "what did you build?" but "what's actually blocking you?" If you submit a check-in that's three words and a shrug, you get pushed back. If you're about to give up, someone notices before it happens.Milestones are enforced. Each tier has hard deadlines. Miss your milestone check-in and your sprint pauses until the founder reviews your proof. This is not optional. The deadline is the product.---### Three tiers — pick where you are right nowBronze — 13 daysYou have an idea or a half-started project. Goal: a deployable first version. Working, live, something you can show. Not polished. Shipped.Silver — 21 daysYou've started but you're stuck. A specific blocker: a broken integration, a feature you can't figure out, a design decision you keep avoiding. Goal: a meaningful milestone. Something that moves the project from "stalled" to "moving."Gold — 30 daysYou're almost done. 80% complete, 0% shipped. The gap between what exists and what's live is not technical — it's execution. Goal: shipped. Deployed URL, working demo, or live AI workflow. No more "I'll get back to it."---### Why this works when everything else doesn'tAI will give you a perfect plan. It won't notice when you skip Day 4.The mechanism is not accountability in the abstract. It's the Witness Effect: when someone specific is watching — not a faceless app, not a streak counter — the cost of stopping goes up. A founder who reads your check-ins and pushes back when needed changes the calculus of quitting.Every time your word count drops below 30 words or you miss two check-ins, the system flags it. The prompts shift. The founder sees it in a queue. You don't fall through the cracks quietly.This is not a course. There are no videos to watch, no modules to complete, no community forum to check. Just daily prompts, daily check-ins, milestone reviews, and someone who notices when you go quiet.---### Built by a developer, used by developersMVP Builder is built and run by a solo developer with a full-time job — dogfooding the exact problem it solves. Every design decision came from a real constraint: no time to babysit users, no budget for a team, no way to scale without making the system do the work.Daily prompts adapt via Claude Haiku to each user's sprint goal, tech stack, and prior check-in. Milestone gates are enforced in code — not manually. Built on Next.js and Supabase, deployed on Vercel.Cohort #1 result: a developer with a full-time job built a drone mission planner (UAV waypoint system with Leaflet/OSM basemap, KML/KMZ export compatible with DJI Litchi, 532 waypoints flight-tested) in 13 sprint days. From concept to deployed URL while working a full-time engineering job.---### PricingCohort #2 — Founder Price (one-time, not a subscription):- Bronze / 13 days: $67- Silver / 21 days: $117- Gold / 30 days: $179No charge until you're accepted. You pay after the founder reviews your application and accepts you. If you're not accepted, you never pay.7-day money-back guarantee. If you complete fewer than 3 check-ins in the first 7 days, you get a full refund. No questions. The guarantee is designed to protect users who try and find it's not for them — not to protect people who don't show up.Application required. Decided by the founder within 48 hours. ICP filter: you need to show implementation ownership — a deployed URL, a working demo, or a real AI workflow. No accepts without proof you can ship.---### The cost of not actingAnother six months of "I'll get back to it." Another half-finished repo that you mention in passing and then move on. The project that could have been done in March is still on your laptop in October.You know how to build this. The gap isn't skill — it's execution under a 40-hour week with no deadline and no one watching.That's the gap MVP Builder closes.mvpbuilder.io/pipeline
