Talk to the people who will build your platform.

Commerce, agentic platforms and custom platforms.

Every project is designed for its own need; the thinking upstream is part of the assignment.

01
Commerce platforms
Shopify Plus, headless, custom apps, ERP and logistics integrations, migrations. Commerce is what our clients entrust us with most.
- Shopify or Shopify Plus store, theme adapted to the brand
- Headless front end on Hydrogen or Next.js over the Storefront API
- Custom Shopify apps: fulfilment, administration and tailored workflows
See the commerce expertise
02
Agentic platforms

- Framing: use cases, available data, acceptable automation threshold
- Customer-service agent connected to your tools, with human escalation
- Catalogue enrichment: attributes, descriptions, reviewed translations
See the agentic platforms expertise
03

( 05 ) What clients write

Advice included.

Clients arrive with a specification and leave describing something else: the business need understood before the ticket, advice given before the build, needs anticipated that they had never written down. The advice comes with the delivery.
