12-week timeline
Weeks 1–2 discovery and architecture, weeks 3–10 design and build in two-week sprints, weeks 11–12 hardening and launch. Calendar-accurate, not aspirational.

An MVP, the way we build it, is not a prototype and not a proof of concept — it is a shipped product that real users sign up for, pay for or formally commit to. Scope and timeline are fixed at the end of discovery and we hold to them. Pricing is in EUR, all-in, no recruitment markup and no tool surcharges. Intellectual property transfers to the founding entity on creation under a master services agreement that every engineer signs on day one. Engagements are GDPR-aligned by default, with SOC 2 Type II in progress at the firm level, HIPAA-capable for HealthTech and CCPA-acknowledged for US consumer products. See it in practice in our ARIA case study.
What’s inside our MVP engagement
Fixed scope, fixed budget
60–120k EUR all-in, signed off at the end of week two. No scope creep without your written approval and a transparent budget delta — the default answer to creep is the post-launch roadmap.
Senior squad, not interns
One product manager, one product designer, two senior engineers and a QA lead, embedded around the founder. Every CV is real and every seat ships from week one — no juniors hidden behind senior contracts.
Ship-ready stack
Next.js or React on the front, FastAPI or Node on the back, PostgreSQL on AWS, Stripe for billing, Auth0 or Clerk for identity. Boring, proven, investor-friendly — no resume-driven architecture.
Investor-ready handover
Architecture document, test-coverage report, security review, observability dashboard and a 90-day post-launch roadmap. Diligence-ready before your first investor email goes out.
Continue with the same team
Roughly 80% of founders continue with the same squad post-launch on time-and-materials or as a dedicated team. Product knowledge stays in the team, not in a slide deck.

How we ship your MVP in 12 weeks
-
01
Discovery
Weeks 1–2. We lock the product narrative, the top three user flows, the integration map and a target architecture. Output: a fixed price, a fixed scope and a signed SOW before any code is written.
-
02
Design
Weeks 3–4. The product designer ships a Figma file, a lightweight design system and a click-prototype you validate with five to eight target users before we touch the codebase.
-
03
Build
Weeks 5–10. Two-week sprints, weekly demos to the founder, growing automated test coverage and CI on every commit. You see working software every Friday, not at the end.
-
04
Launch
Weeks 11–12. Hardening, security pass, observability and alerting, production cutover and the 90-day post-launch roadmap. You go live with paying users, not with a staging URL.
Engagement models
Fixed Price MVP
Default for founders. 60–120k EUR all-in for a 12-week investor-ready MVP. Fixed scope, fixed timeline, signed off before week three.
Time & Materials Continuation
Post-launch growth on monthly invoicing per named seat. Same squad, same context, no recontracting — ship weekly against a rolling backlog, or add staff augmentation to plug a specific gap.
Dedicated Team
For founders scaling beyond MVP. A long-running dedicated development team you treat as your own, with hiring and retention on us and product priorities on you — a natural path into full SaaS product development.
What an MVP costs — and what drives the price
Most agencies keep the number for a sales call. Here is how we price so you can budget before the first meeting: MVPs are fixed-scope and all-in, quoted in EUR at the end of a two-week discovery, with no recruitment markup, no tool surcharges and no hidden fees. You see the line-item budget before any code is written and sign off on it.
Fixed-price MVP
60–120k EUR all-in. A 12-week investor-ready MVP with a senior squad of one PM, one designer, two engineers and a QA lead. Fixed scope and fixed timeline, signed off at the end of week two — no recruitment markup, no tool surcharges.
Discovery only
The first two weeks, standalone. Product narrative, top user flows, integration map, target architecture and a fixed price and scope for the build. Walk away with a signed SOW and a diligence-ready plan even if you build the rest elsewhere.
Time & Materials continuation
Monthly, per named seat. Post-launch growth with the same squad on a rolling backlog — no recontracting. Roughly 80% of founders continue this way after week 12, switching the SOW from fixed-price to T&M.
What moves the number: the integration count (billing, auth, third-party APIs); regulated workloads (GDPR is in scope by default, but PCI DSS scoping for payments and HIPAA-capable architecture for HealthTech add discovery and controls work); platform count (web only vs. web plus mobile); and the depth of each core flow. GPU, third-party tooling and cloud spend run on your own accounts, so you keep the cost lever. Anything outside the signed scope goes on the 90-day post-launch roadmap with sized estimates rather than a silent timeline extension.

Why US & EU founders pick YuSMP for MVPs
GDPR-aligned · SOC 2 Type II in progress · HIPAA-capable · CCPA-acknowledged
Investor-ready by week 12
You ship a working product with real users, not a wireframe and a pitch deck. Architecture document, test coverage and security review are diligence-ready before your first investor email.
Founder-friendly economics
60–120k EUR fixed, all-in. IP transfers to the founding entity on creation under the MSA. You hold the GitHub org, the cloud accounts, the Stripe account and every credential.
Compliance from day one
GDPR-aligned by default, SOC 2 Type II in progress, HIPAA-capable architecture for HealthTech, CCPA-acknowledged for US consumer products. Compliance is in scope from week one, not bolted on later.
PCI DSS and HIPAA scoping are available for payments and HealthTech MVPs — we align directly with your QSA or BAA-ready vendors during discovery.
What clients say
We had a concept and tight timelines. YuSMP converted a Flutter skeleton into a production-ready nutrition app with a calorie engine, meal plans, and App Store subscriptions in four months. 90-day retention exceeded our benchmark by 30%.
Prototyping before committing to a full mobile build is smart, but only if the prototype is honest. YuSMP delivered a high-fidelity prototype that gave us enough user feedback to cut 20% of planned scope before a single line of production code was written.
Frequently asked questions
How much does an MVP cost with YuSMP?
Fixed-scope MVPs land between 60k and 120k EUR, all-in. That covers a senior squad of one product manager, one product designer, two engineers and a QA lead for the full 12 weeks, plus all delivery overhead. The exact number depends on integrations, regulated workloads and platform count (web only vs. web plus mobile). You see the line-item budget at the end of week two and sign off before any code is written. There are no hidden fees, no recruitment markup and no tool surcharges.
What can realistically ship in 12 weeks?
A real product, not a demo. Typical 12-week MVPs include authentication and accounts, two or three core user flows, a billing or onboarding integration, an admin or operator view, and basic analytics and error reporting. That is enough to onboard your first 100 paying users, run a pilot with a design partner, or close a pre-seed or seed round. We deliberately cut anything that does not move that needle and put it on a post-launch roadmap with sized estimates.
Who owns the code and IP?
You do, from day one. The master services agreement transfers all intellectual property to the founding entity on creation, and every engineer signs an individual IP assignment and NDA before they touch the repository. You hold the GitHub or GitLab organisation, the cloud accounts, the domain registrar, the Stripe account and every credential. We work inside your environment, not ours. At handover you receive an architecture document, a runbook and full credential rotation.
What if scope changes mid-engagement?
Scope is fixed by mutual sign-off at the end of week two and we hold to it. Real life happens, though, so we run a lightweight change-request process: anything you want to add gets sized in hours and EUR within one business day and either swaps in (we drop something of equivalent size) or is added with a budget delta you approve in writing. We never silently extend timelines or invoices. The default answer to creep is the post-launch roadmap.
Can we continue with the same team after the MVP launches?
Yes, and most founders do. Roughly 80% of our MVP clients continue with the same squad on a time-and-materials or dedicated-team basis after week 12, which keeps product knowledge inside the team. Continuation requires no recontracting; we simply switch the SOW from fixed-price to T&M with monthly invoicing per named seat. If you raise a round and want to bring engineering in-house, we provide a 60-day knowledge-transfer window at no additional fee.
How do you handle GDPR, SOC 2, HIPAA compliance for an MVP?
We build GDPR-aligned by default: lawful basis, DPA, data residency, deletion paths and consent flows are in scope from week one, not bolted on later. SOC 2 Type II is in progress at the firm level, so MVPs inherit aligned controls (SSO, MFA, encrypted disks, audit logging) out of the box. For HealthTech we deliver HIPAA-capable architecture with BAA-ready vendors. PCI DSS scoping is available for payments products. CCPA notice obligations are acknowledged for US consumers.
