MVP Development Services for US & EU Startups

MVPs are fixed-scope and tiered by idea maturity, all-in and quoted in USD. A hypothesis check runs from $1,800 (2–3 weeks); a classic single-platform MVP from $6,900 (4–8 weeks); a multi-platform MVP+ with integrations, payments and roles from $13,800 (8–12 weeks). 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 discovery and sign off before any code is written. There are no hidden fees, no recruitment markup and no tool surcharges.

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.

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.

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 USD 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.

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.

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.

All three, and we recommend the right platform split at discovery. Most B2B SaaS MVPs start web-only because the sales motion requires a desktop dashboard and the first users are on laptops. Consumer-facing products often start on one mobile platform (iOS first for US/EU markets) and add web or Android in the post-MVP phase. Cross-platform (React Native or Flutter) is the right call when the MVP must work on both iOS and Android simultaneously — which typically adds four to six weeks versus single-platform and is scoped into the MVP+ tier. We will tell you our honest recommendation, not default to the more expensive option.

We use a single-question filter at discovery: does removing this feature make it impossible to validate the core hypothesis? If not, it goes on the post-launch roadmap with a sized estimate. In practice, scope converges around one to three core user flows, an auth layer, one or two integrations (payment, identity, or data), and a basic admin or operator view. Discovery deliverables include a feature list signed off by both sides — nothing is added mid-build without a change request that shows the cost and the trade-off.

Every MVP ships with event analytics (Mixpanel, PostHog, or Amplitude — your choice) wired to the core user flows so you have activation, retention, and conversion data from the first user. Application monitoring (Sentry for error tracking, Datadog or a cloud-native equivalent for infrastructure) is included in the MVP+ tier and optional in the Classic. We instrument the three or four metrics your investor pitch and product hypothesis depend on — not a 200-event schema you will never look at.

A PoC proves a technical assumption works — it is throwaway code and not user-facing. A prototype (Figma, InVision) proves a UX assumption — it is not executable and not deployable. An MVP is a live, deployable product that real users can sign up for, pay for, and use in production. Our MVPs include auth, data persistence, error handling, basic observability, and a handover package (architecture doc, runbook, credential rotation). The gap between prototype and MVP is typically eight to twelve weeks of real engineering.

Yes — that is the intended progression. A hypothesis check ($1,800, 2–3 weeks) is a no-code or minimal-code spike: a clickable Figma with a wait-list form, a Stripe payment link, or a wizard-of-oz backend. It validates demand before any real build. If the hypothesis check confirms a market signal, we convert it into a full Classic MVP SOW: you get a credit toward the Classic tier for work already completed, and the scope document is pre-populated from what we learned. Roughly 60% of hypothesis checks at YuSMP progress to a Classic MVP within 90 days.
