What Les-Tilleuls.coop does

Les-Tilleuls.coop is a 100% worker-owned cooperative company (SCOP/SARL) registered in Lille Métropole, France, operating since 2011 under French cooperative law with self-managed, egalitarian governance and no external investors or parent entity. The cooperative specializes in API development, web development, and cloud architecture consultancy, and employs 70+ worker-members across 5 offices in France (Lille/Lomme, Nantes, Lyon, and the Paris area).

The cooperative's core technology assets are two open-source products created by founder and CEO Kévin Dunglas: API Platform, a PHP framework supporting REST, GraphQL, JSON-LD/HAL/JSON:API standards with automatic OpenAPI documentation that has become widely adopted in the PHP ecosystem; and FrankenPHP, a modern PHP application server released in 2024 with built-in HTTPS, automatic TLS certificates, worker mode, and native Laravel Octane support. The cooperative also maintains Mercure, an open-source real-time push protocol, and operates the annual API Platform Conference. Kévin Dunglas sits on the Symfony framework core team and is a lecturer at Lille University, with additional employees serving on the API Platform core team.

Revenue is generated through three primary streams: technical consultancy services delivered to enterprise clients including France TV, Decathlon, ARTE, IZI by EDF, and Vestiaire Collective, focused on API design, web applications, cloud architecture, and DevOps/Kubernetes/SRE work; the "Masterclass" professional training program covering Symfony, Kubernetes, Vue.js, React, Go, Docker, Laravel, API Platform, Mercure and related technologies, priced at €1,200-€1,800 per attendee and Qualiopi certified (eligible for French OPCO financing); and cloud/DevOps consulting. Go-to-market is community-led: open-source maintainership, 200+ conference animations, technical blogging, and newsletter distribution function as top-of-funnel demand generation, with direct enterprise field sales closing consultancy and training engagements. The cooperative is certified as a B Corp.

Direct peers

• Smile (Open Source): European open-source solutions integrator with strong French presence, offering web development, integration, and training around Drupal, Symfony, and other open-source stacks. Closely comparable business model and customer base to Les-Tilleuls.coop.
• Theodo: French web and mobile development agency of similar scale serving enterprise clients on modern stacks (including Symfony and React/Vue). Comparable as a French full-stack consultancy competing for overlapping enterprise digital projects.
• SensioLabs: French company that created the Symfony framework and operates a similar consultancy + training + open-source model. Most directly comparable to Les-Tilleuls.coop because it sells Symfony/API training, holds core-team influence, and serves enterprise clients on similar technology stacks.

Emerging players

• Clever Cloud: French PaaS provider with first-class support for PHP, Symfony, and API Platform deployments. Comparable as a French open-ecosystem infrastructure player whose cloud hosting overlaps with Les-Tilleuls.coop's cloud consulting and FrankenPHP deployment work.
• Platform.sh: Cloud platform purpose-built for PHP/Symfony applications and used heavily by the API Platform community. Overlaps with Les-Tilleuls.coop's cloud/DevOps and FrankenPHP deployment services for the same ecosystem customers.
• Laravel: Creator/maintainer of the Laravel PHP framework, which is closely adjacent to the Symfony ecosystem in which Les-Tilleuls.coop operates (FrankenPHP is now Laravel Octane's default server). Comparable as a creator-led PHP ecosystem player with overlapping developer audience.

Others

• Blackfire.io: PHP performance profiling tool from SensioLabs used in conjunction with Symfony and FrankenPHP. Comparable as a sibling product in the same PHP performance-and-observability ecosystem that Les-Tilleuls.coop recommends and integrates for clients.

Regional players

• AOE: German full-service digital agency with strong PHP/Symfony, TYPO3, and API capabilities serving enterprise clients. Comparable services and tech stack, but primarily serves DACH-region enterprises rather than competing directly in France.
