SFEIR becomes a Preferred partner in Anthropic's Claude Partner Network, taking its clients to 10x with agentic AI
AI executes. Humans govern. The project learns. SFEIR clears a demanding milestone and brings its clients the Claude practice it first ran on its own teams.
Paris, October 5, 2026. SFEIR is now a Preferred partner in the Claude Partner Network Services Track, after joining the network at the Select level.
The Preferred status recognizes the work of SFEIR's certified teams, from upskilling its experts to deploying Claude in client organizations. For companies, this means end-to-end support: scoping of use cases, experimentation, team training, industrialization and production.
The Preferred level is earned. It rewards months of collective work: certifications earned one by one, evenings of revision, exams squeezed between client meetings, and engagements carried through to production. More than 170 SFEIR people, over one in five across the group, hold at least one Claude certification recognized by Anthropic. This critical mass brings every client high impact and a quality of support built by experts who work with Claude every day.
AI for IT: SFEIR's agentic SDLC, proven with Claude Code. SFEIR engineers have worked with Claude Code since spring 2025, and every Sfeirian since early 2026. The method belongs to SFEIR: an SDLC designed for agents, with eleven phases of which code generation is a single step. Humans hold three gates (Define, Plan and Ship) and agents handle the rest. Only captured output counts as proof, since an agent reporting that tests pass proves nothing. Four parallel reviews cover code, security, tests and performance. Two Compound phases turn lessons into rules that the next cycle reloads. The method adapts to each client's environment and cloud of choice. After ten cycles, SFEIR measures about 30% fewer correction iterations.
AI for Business with Claude Cowork. Claude Cowork brings Claude Code's agentic way of working to people who write no code. SFEIR teams work in Claude for Enterprise every day, and Cowork reached the group's leadership and staff functions first. For clients, SFEIR deploys Cowork like a cloud landing zone: security and admin settings first, then connectors to the client's systems and organization-wide skills such as house-style slides and proposal templates. AI Champions trained inside the client's teams lead adoption, which SFEIR measures in business units rather than licenses. Where a process needs more, SFEIR builds custom agents on the Claude API, connected through MCP, with cost per outcome as the measure.
Engineers inside client teams. SFEIR's forward deployed engineers join client teams from diagnostic to run, then hand over. SFEIR Institute, the group's training arm, trains 6,000 professionals every year. At Asys, a French software publisher, it trained and certified 50 developers on Claude Code in under two months.
"The Preferred level is demanding. We cleared it thanks to experts who made certification a professional reflex. AI executes, humans govern, the project learns. Our own website took six months to build in 2021, and today we build it in a day, with humans signing off at every key gate. This partnership gives us more ways, together with Anthropic, to take our clients to 10x. We measure our success by how fast our clients stop needing us."
Xavier MULLER, CEO, SFEIR Group
"This level confirms a conviction we have held for a long time: AI is judged in production, in the hands of the teams who use it every day. I thank every colleague who gave their time to master Claude. Our ambition is to keep certifying, supporting and deploying alongside Anthropic, with the same rigor."
Didier Girard, Managing Director, SFEIR Group
Our certified Claude expertise helps our clients go from idea to production, and this partnership strengthens our collaboration.
