COSESO

COSESO is a French automation, AI, and custom development agency helping businesses connect their tools, streamline operations, and build reliable digital systems.

As a Zapier Solution Partner, we help startups, SMEs, and growing teams automate the processes that slow them down: lead routing, CRM updates, client onboarding, document generation, e-commerce operations, reporting, support workflows, internal notifications, and AI-assisted qualification.

Our strength is combining Zapier’s no-code automation capabilities with custom technical expertise. When Zapier is enough, we keep the setup simple, clean, and maintainable. When a workflow needs more control, we can extend it with APIs, webhooks, custom scripts, databases, interfaces, or AI logic.

Beyond automation, COSESO designs and develops the digital products that often sit around these workflows: SaaS platforms, internal tools, e-commerce systems, web apps, dashboards, and custom back-office solutions. This allows us to build automations that fit into a broader business system, instead of creating isolated workflows that become hard to maintain.

We have delivered projects across AI, SaaS, e-commerce, marketplaces, CRM workflows, internal operations, and custom web platforms. Our approach is pragmatic: understand the real process first, choose the simplest reliable architecture, document what we build, and create systems that teams can actually use and improve over time.
