The verdict in three sentences
A serious B2B SaaS MVP, delivered in 12 weeks by an external team for a Berlin startup, costs EUR 25,000 to 60,000 in 2026, based on day rates of EUR 550 to 750. The right split is three sprints: the core business flow, Stripe subscription billing, then the minimum polish for the first paying customers. Compared with hiring a salaried CTO at EUR 90,000 to 120,000 a year before equity, an external MVP gets you to traction faster and keeps the cap table clean.
What a B2B MVP must prove before a pre-seed round
A business angel or pre-seed fund does not invest in a Figma mock-up. They want to see real users who come back and ideally a few paying customers. Your MVP must therefore cover one value flow, end to end, without frills:
- signup of a client company and invitation of its team members;
- the core feature that solves the problem, and nothing else;
- a monthly or annual Stripe subscription with a trial period;
- a minimal dashboard and transactional e-mails;
- usage tracking (activation, 4-week retention) to feed the deck.
The three four-week sprints
| Sprint | Content | Person-days | Budget (EUR 650 day rate) |
|---|---|---|---|
| Scoping (week 0) | Workshops, user journey, key mock-ups, backlog | 5 to 8 | EUR 3,250 to 5,200 |
| Sprint 1 (weeks 1-4) | Multi-company accounts, roles, core feature v1 | 20 to 30 | EUR 13,000 to 19,500 |
| Sprint 2 (weeks 5-8) | Stripe subscriptions, dashboard, e-mails, key integration | 15 to 25 | EUR 9,750 to 16,250 |
| Sprint 3 (weeks 9-12) | Polish, tests, analytics, production launch, onboarding | 10 to 20 | EUR 6,500 to 13,000 |
| Total | MVP ready for 10 to 30 pilot customers | 50 to 83 | EUR 32,500 to 53,950 |
A very focused MVP can go down to EUR 25,000. Above EUR 60,000, it is usually no longer an MVP but a V1 whose scope was never trimmed.
The costs founders forget, and the CTO comparison
| Item | 2026 order of magnitude | Comment |
|---|---|---|
| Cloud (Vercel, Supabase, AWS) | EUR 100 to 300 / month | Enough for a few hundred users |
| Stripe Billing | 1.5 % + EUR 0.25 per EU card payment, + 0.7 % Billing | Variable, proportional to revenue |
| Transactional e-mail, monitoring | EUR 30 to 100 / month | Essential from the first customers |
| Post-launch maintenance and fixes | EUR 1,500 to 4,000 / month | Iterations on pilot feedback |
| GDPR compliance (records, DPA, EU hosting) | EUR 1,000 to 3,000 | Required by B2B buyers |
| Salaried CTO in Berlin, 12 weeks | EUR 28,000 to 36,000 gross incl. employer costs, plus 3 to 6 months of hiring | One person, plus 5 to 15 % equity |
German founders can also look at the EXIST start-up grant for university spin-offs or Berlin regional programmes, which can cover part of living and material costs. Apply early: expenses committed before approval are usually not eligible.
Mini case study
Camille, a non-technical founder in Berlin building software to manage electrical safety certifications for construction SMEs, targets a EUR 600,000 pre-seed round. She orders an MVP of 68 person-days at EUR 650, or EUR 44,200, delivered in 12 weeks.

The alternative was a senior CTO at EUR 110,000 a year plus 10 % equity, after a 4-month search. Three months after launch, 12 pilot companies pay EUR 149 a month, or EUR 1,788 MRR with 92 % retention. Those real metrics weigh more in the deck than any prototype, and the MVP cost is about 7 % of the amount raised, with no equity given away. She hires her first in-house engineer after the round. 2026 order of magnitude.
FAQ
How much does a B2B SaaS MVP cost in Berlin in 2026?
Between EUR 25,000 and 60,000 for 12 weeks of development with an external team billing EUR 550 to 750 a day. The typical figure is around EUR 40,000 to 45,000.
Is twelve weeks realistic?
Yes, if scope is limited to one value flow and the founder decides quickly. Overruns almost always come from features added mid-sprint.
Freelancer, agency or salaried CTO?
A single freelancer is cheaper, around EUR 550 a day, but concentrates risk. An agency brings design, development and testing in parallel. A CTO costs EUR 90,000 to 120,000 a year plus 5 to 15 % equity, and takes months to hire.
Can grants fund part of the MVP?
Possibly, through EXIST for university spin-offs or regional Berlin programmes, usually covering a share of eligible costs. Check eligibility before signing the development contract.
Who owns the code?
The founder, upon payment, through an IP assignment clause in the contract. Investors check it systematically during due diligence.
