Introducing Grospan 4
Software,

Studio Sète
A studio for the long horizon.
We design, build and operate software with three commitments — durability, transparency and proportional ambition.
Durability
Systems that age well.
We optimise for codebases and integrations that stay readable, debuggable, and inexpensive to operate three years after launch — not just on launch day.
Transparency
Outputs you can audit.
Every automation we ship comes with traces, evals and a written rationale. If a result surprises you, you can find out why in minutes, not days.
Proportion
Right-sized ambition.
We don't sell rebuilds when a refactor will do. Our first deliverable is usually a clearer map of the problem and a smaller plan than you expected.
The platform
Grospan 4 — for teams that ship.
A unified workspace and API for building production-grade automations, internal tools and customer-facing AI features. Latency you can plan around. Outputs you can audit.

Built for the work, not the demo.
Support automation
Tier-1 deflection that knows when to escalate. Measured against CSAT, not just resolution rate.
Pipelines & ETL
Reliable ingestion and transformation with full lineage, retries and human-readable errors.
AI-native features
Search, generation, summarisation and structured extraction shipped behind your product UX.
How we work
Four steps, no surprises.
- 01
Discovery
A two-week sprint to map the problem honestly. You leave with a written brief — and the option to walk away.
- 02
Prototype
We ship a thin slice end-to-end so the team can use it, react to it, and refine the scope before we commit.
- 03
Production
Hardening, evals, observability and rollback. We deploy in increments small enough to verify.
- 04
Handover
Documentation, training, and a runbook your team owns. We end engagements when the system runs itself.
Plays well with your stack.
Native, first-party connectors maintained by us — plus an HTTP toolkit for everything else.

Research
A practice of patient engineering.
Our research notes track how we evaluate models, instrument systems, and decide what is safe to deploy. We publish what we learn, including what didn't work.

"We replaced six brittle scripts with one Grospan workflow. The team can finally read what the system is doing."
"The honesty about limits is what made us choose them. It made the rollout uneventful — which is the goal."
Engagements
Engineering as a partnership.
Whether you need a discovery sprint, a production-ready prototype, or an embedded team for a year, we scope honestly and deliver in increments you can verify.
