An idea isn't enough, you need good technical decisions

Don't just tell us what to code.

A product idea or a SaaS already live: what you're missing is a team that makes the right technical decisions, not just one that executes a spec.

Tell us what you want to achieve. We question features, complexity and technical assumptions when a simpler solution exists.

What we take care of

One team accountable for your SaaS's entire technical chain, from architecture to production monitoring.

Product and technical scoping, architecture, interface, secure login, subscriptions and payments, integrations with your tools, admin back office.

Then go-live on hosting in your name, monitoring, tests before every release and ongoing improvements. The team that designs the architecture is the one that evolves it.

B2B SaaS, vertical platforms, internal subscription tools, multi-tenant platforms, client portals, marketplaces. What they share: an architecture built to last.

President, Hyperion Défense

We've now been working with Byrsa Tech for 7 years, across 3 different projects. They've always made sure our applications stayed robust, never hesitated to challenge our choices, and stuck with us through many pivots. They're exactly the kind of company we needed.

Our philosophy

Launch fast, without building disposable software.

The simplest architecture that meets today's need while keeping room to grow. No complexity to impress, no shortcuts that cost you later.

What stays in your control

The code and data are yours; nothing locks you in. Your contact is an engineer, not a salesperson.

How we work

Frequently Asked Questions

About 4 weeks for a first testable version. The tighter the first scope is around what matters, the easier that timeline is to hold.

Not necessarily: we make technical decisions with the standards of an in-house CTO. When you hire your own team, we prepare the handover with you.

Yes, fully, from day one. Code, infrastructure and documentation are yours: you never depend on us to keep evolving your product.

Yes. We start with an audit of the code, architecture and infrastructure to decide what to keep, refactor or rebuild, and give you a realistic estimate.

Yes. The architecture is sized for your likely growth, with no needless complexity up front and no hidden ceiling later.

Yes. Hosting is opened in your name: you pay the provider directly and stay in control. We set it up, deploy the product and monitor it as part of maintenance, with one point of contact if something breaks.

We stay involved: fixes, new features and support, from a team that already knows your product. Key decisions often come after the first user feedback.

Yes, when it brings measurable value to your users. We build it into the existing architecture rather than bolting it on.
