The verdict in three sentences

In 2026, discovery takes 2 to 3 weeks, an MVP ships in 8 to 14 weeks, and a full v1 needs 4 to 7 months. The cadence rests on 2-week sprints with a demo at the end of each, which makes the plan verifiable. An investor doesn't fund a date, they fund delivered milestones: better to promise an MVP in 12 weeks and hit it than announce 6 weeks and slip.

Phases, deliverables and duration by project size

Each phase produces a concrete deliverable. That's what lets you steer and reassure a board.

What really speeds up or slows down the plan

At equal effort, a few organizational factors shift the timeline by 30 to 50%. Spotting them early avoids nasty surprises in front of investors.

An available client-side product owner is the most underrated lever: alone, they win or lose several weeks through fast decisions.

Mini case study

Yannick, founder of a B2B marketplace project in Bordeaux, must present a credible roadmap to business angels in 3 months. We scope a milestone plan: discovery (2 wks), design (3 wks), transactional MVP (10 wks) — a usable live demo in 15 weeks. He pitches not a promise but a product that takes a real order with payment split. The raise rests on demonstrated traction, which noticeably improves valuation versus a mere slide deck.

FAQ

Can you ship an MVP in 4 weeks? Rarely for a truly billable product. 4 weeks suffice for a clickable prototype or demo; a sellable MVP with auth and billing needs 8 to 14 weeks.

Why 2-week sprints? Because they force regular demos and fast adjustments. You see the product advance every two weeks rather than discovering the result at the end.

How do you hold a plan against surprises? By freezing the MVP scope and treating every new idea as a post-MVP backlog item. Scope discipline is the first guardian of the timeline.

Should everything be designed before coding? No: we design the MVP's key screens, then iterate. Chasing pixel-perfect across the whole app before the first commit needlessly extends the timeline.

How long for a v1 after a validated MVP? Typically plan 3 to 5 extra months to move from a single-feature MVP to a sellable v1, depending on the modules added.
