Web apps & SaaS

A SaaS MVP or internal tool should be an asset, not a liability. We build applications with the engineering discipline of a product team — typed, tested, documented, deployed through CI/CD — at a price fixed before the first commit.

Engineering, not prototyping

Every build gets a typed codebase, database migrations, automated tests and a deploy pipeline from day one. When the project ends you hold a documented system that any competent developer can extend — the opposite of the freelancer prototype that has to be rewritten at the first sign of traction.

Fixed scope, fixed quote

Agency app development usually means open-ended hourly billing. We scope the build with you, put the price in writing, and hold it. Builds start at €2.200; larger systems get a fixed quote after a scoping session. Change requests are priced the same way: in writing, before the work.

EU data handling from the schema up

User data lives in EU-hosted databases. Authentication, file storage, e-mail and analytics are chosen with GDPR in mind, so your processor list stays short and your privacy policy stays honest. For B2B products selling into Europe, that is a sales argument as much as a legal one.

[TARIFF]

App and SaaS builds start at €2.200 with a fixed quote agreed before work starts. Ongoing product engineering is available on the Studio plan at €1.200/mo.

Frequently asked questions

What does a SaaS MVP cost?

Builds start at €2.200. After a scoping session you receive a fixed, written quote for the agreed scope — no hourly billing, no open-ended invoices.

What stack do you build with?

Typed TypeScript codebases, PostgreSQL, and containerized deployments with CI/CD. We choose boring, well-documented technology your future team will thank you for.

Can you take over or extend an existing application?

Yes. We audit the codebase first, tell you honestly what state it is in, and quote the work fixed. The Studio plan (€1.200/mo) covers ongoing feature development with senior engineering time.

Is my users’ data GDPR-compliant?

Data is stored on EU infrastructure and third-party services are selected for GDPR compatibility. We document the data flows so you can answer a DPA questionnaire without guessing.
