SaaS platform development built for speed and longevity

Everything a software product needs to run as a service: the product itself, customer accounts and permissions, billing and subscriptions where you need them, the cloud set-up, monitoring and the release process. FlightLabs builds it in the order that gets one workflow in front of customers first.

Yes. We review the code, the architecture and the open risks first, then tell you what to keep, what to fix and in which order. If it needs more than that, our codebase recovery work stabilises it before new features go in.

Multi-tenant for most B2B products: one platform, each customer's data kept apart, and lower running costs. Where a customer needs its own instance for data or contract reasons, we design for that from the start.

A proven, widely used one, usually TypeScript and React, Node.js or Python, PostgreSQL and a major cloud. We agree it with you before the build, and we work in your stack if you already have one.

By agreeing the tenant model, the data model and the permissions before the first feature, and keeping them covered by tests. Features will change; those foundations shouldn't have to.

Yes. We host in EU regions of the major clouds, in your accounts, so you keep control of the infrastructure, the data and the bills. If a customer needs a particular country, we design for that.

If consumers use it, most likely yes: Germany's BFSG, which implements the European Accessibility Act, covers services such as e-commerce and banking for consumers since 28 June 2025. B2B-only platforms are usually outside it, but larger customers often ask for it. We build to WCAG 2.1 AA by default.

One workflow works end to end early in the project, and you see it in staging with a demo every week. The time and cost of a v1 you can sell depend on the scope; the written proposal after our free intro call sets out the plan, the cost model, the timeline and the risks.
