"How long will it take?" — the second question every founder asks, right after cost. And like cost, the honest answer is a range.
Most articles on this topic are written by agencies who nudge every answer toward big, long, expensive projects. Here's the straight version.
The short answer
- Simple app - 4 to 8 weeks
- Standard app - 3 to 4 months
- Complex platform - 6 to 12 months
Most focused MVPs land between 6 and 12 weeks. Anything past 6 months is either genuinely complex or suffering from unclear scope - and the second one is far more common.
What actually speeds it up
- Narrow, ruthless scope in v1
- Developer who has built similar systems before
- Modern stack - Next.js + Prisma + PostgreSQL lets one developer move fast without a big team
- AI tools - in 2026 they compress routine coding by 30–50%, but they speed up the typing, not the thinking
What quietly slows it down
- "Can we also add…" mid-build - number one timeline killer
- Too many features in v1
- Slow feedback loops - if approvals take a week, calendar stretches even when work doesn't
- Rushing - demanding unrealistic deadlines adds 15–30% in rework
The one thing most people skip
Discovery and planning. Skipping it to "save time" is the single most expensive shortcut. Two weeks of clarity upfront saves months of rebuilding later.
