Our Story — French digital studio since 2013

In short

55 · agency was founded in Paris in 2013 and is an independent French digital studio. It has grown to around forty people across product, design, engineering and AI, with offices in Paris, Nice (Cagnes-sur-Mer) and Lyon (Villeurbanne).

Milestones

Thirteen years,
step by step.

2013 — The studio is born

55 · agency is founded in Paris by three developers, with one obsession: ship mobile apps built to a higher standard than the market was accepting at the time.

2015 — First app past one million users

An urban mobility application we designed and built crosses the symbolic one-million-user mark.

2017 — The Nice office opens

The studio expands to the Côte d'Azur, closer to regional clients and to the Sophia Antipolis talent pool — Europe's largest science park.

2019 — The web division launches

Premium brochure sites, e-commerce and SaaS platforms: we extend the craft beyond mobile.

2021 — Lyon office and 30 people

A third site opens in Villeurbanne, serving the industrial, healthcare and logistics economy of the Auvergne-Rhône-Alpes region.

2023 — First AI engagements

Business chatbots, retrieval-augmented generation, copilots: AI becomes a practice that cuts across every engagement rather than a side project.

2026 — The AI division goes official

A dedicated artificial intelligence team, work across the Anthropic, OpenAI and Mistral model families, and a repositioning as a full digital studio — mobile, web and AI.

What has not changed

Independent, and intending to stay that way.

Thirteen years in, the studio has no external shareholder and belongs to no group. That is a deliberate choice, and it has practical consequences for clients: we are free to recommend the technology that fits rather than the one a parent company resells, free to turn down a project that does not hold up, and free to keep our pricing public.

The second constant is that we ship. Every engagement ends with something live — an application on the stores, a site in production, a system your teams actually use. Not a deck.
