WHAT WE BUILD
The business software your team opens every day.

Custom CRM
Your customers, quotes and follow-ups, mapped to your own sales stages.
03
Quotes and documents
Quotes, job invoices and reports generated straight from your data, as PDFs.
04
Built-in agents
An agent that triages requests, drafts a quote or summarizes a file, always with a human approval step.
WHY CUSTOM
Software that grows with your business, not against it.
Custom isn't always the right answer. Here's how we decide together, during scoping.
AGENT JOHN
Every system ships with an agent that keeps it evolving.
Your team describes a change inside the application, in plain language. Three agents with separate permissions handle it, on whichever model provider fits the task, and nothing reaches production without your approval.
Read how Agent John works01Agent John asks one question at a time and files a ticket with acceptance criteria.
02A second agent reads the code, read-only, and proposes a change.
03A human reviews the analysis. Without that approval, nothing moves.
04A third agent opens the pull request, which is reviewed before it ships.

CASE STUDY · INDUSTRIAL PACKAGING DISTRIBUTOR
A custom ERP replacing a no-code tool that had outgrown its limits.
This French distributor runs two logistics platforms and two business models: stockist and commission sales agent. Its no-code tool slowed down with volume, fit both models poorly, and gave no consolidated view of revenue or margin. We built its ERP from scratch.
- Stock tracked by purchase unit (kilos, rolls, pieces), at weighted-average cost
- Two order paths: from stock, or direct from the factory with automatic supplier order consolidation
- Quotes, order acknowledgments, delivery notes, invoices and credit notes, in compliant continuous numbering
- Sales rep commissions calculated once an order is invoiced and shipped
- A live dashboard: revenue, margin, order book, aged receivables
FULL HISTORY MIGRATED
2,700+orders migrated

Who hosts and maintains it?
We do, by default, on infrastructure you choose. Your change requests go through Agent John.
