Locked into six-month contracts before you’ve seen a single screen.

Ship software & AI like a real team did it.
Rayl is the platform founders and teams use to ship custom software, AI, SaaS, and marketplaces — without the agency overhead, the six-month hiring cycle, or the “we’ll get back to you” silence.
Live · shipping for 11+ partners
★★★★★ Senior team, no juniors on your project
The problem
Building software is harder than it should be.
You’re either paying €150k+ to an agency and waiting three months, or hiring four people who haven’t even started yet. Or, more likely, both.
Six months until your team is even running.
By the time the second engineer starts, your roadmap is already stale.
Demos look great. Production looks broken.
RAG that hallucinates, agents that loop, costs you didn’t see coming.
GDPR, PSD2, AML — every product gets harder.
You can’t ship in the EU without all of them. Most teams underestimate it.
Five vendors. Three integrations. One headache.
Stripe + Auth0 + Vercel + Postgres + Inngest + … the stack runs you.
What Rayl does
One team. End to end. Senior all the way down.
Scope in days, not months
Concrete proposal, concrete quote, within a week of first contact. No discovery theatre.
Senior engineers only
Every person on your project has shipped real production software at scale. No bench warming.
Production-grade from day one
Testing, monitoring, CI/CD, error tracking — the boring layers that decide whether you ship or not.
AI baked in
Custom models, agents, RAG, copilots — built on the same stack we use for ourselves.
EU-hosted, GDPR-aligned
Data stays in the EU. Privacy is a default, not a feature you bolt on later.

Built for ∞ scale
From your first user to your millionth.
The same architecture powers a 200-user beta and a 200,000-user product. Multi-tenant by default, observable everywhere, designed so you don’t have to rebuild when growth hits.
- Multi-tenant from day one
- Background jobs, queues, schedulers
- Distributed tracing & structured logs
- Read replicas, caching, async patterns

- Tests as part of the work, not after
- Architecture decision records (ADRs) for the why
- Postgres-first, with sensible defaults
Default stack — swap as needed

What clients say
Honest, on-time, and the code holds up.
Rayl shipped the first version of our product in six weeks. The code we got back was the kind we’d be proud to have written ourselves.
Honest scoping. They told us what we couldn’t do — that’s the line I’ve been waiting to hear from a vendor for years.
We’d been quoted €180k by a Brussels agency. Rayl shipped the same scope faster and the code didn’t need rewriting.
Friday demos, weekly invoices, Slack response under fifteen minutes. Working with Rayl feels like having a senior team next door.
