Our Services
Discover our full expertise to transform your business: custom development, AI automation, product growth and strategic consulting.
One promise: deliver a working business tool, not a slide deck
Codea is an automation and product agency for SMBs. We own five canonical services that cover the entire build journey of a custom internal tool - from validating an idea with an MVP to deploying an AI agent on top of your data. Each engagement is anchored to a measurable business outcome, scoped on a 21-day delivery window, with ROI guaranteed by contract.
We do not sell hours, we sell outcomes. That is why we work with a flat per-scope pricing and an explicit guarantee: if the agreed business outcome is not reached within the agreed window, we keep iterating at no extra cost. This rule applies to every service listed below - whether it is a custom SaaS, an n8n workflow, an AI chatbot or our e-invoicing compliance package.
The four pillars below regroup our services by stage of maturity: build (product and engineering), automation and AI (n8n + LLM agents), growth (analytics, SEO, product) and consulting (strategy, e-invoicing). Pick what fits your stage, or combine several pillars - most clients stack two or three.

Frequently asked questions
How does Codea pick the right service for my problem?+
We start with a 30-minute discovery call to map your goal, constraints and existing tools. From there we propose one of the five canonical services (MVP & POC, custom SaaS, n8n automation, AI agents, e-invoicing) or a combination, scoped against a hard 21-day delivery window with ROI guaranteed by contract.
How quickly can a service ship to production?+
An MVP or POC ships in 3 weeks. A custom SaaS ships in 21 days when the scope is locked. An automation workflow on n8n is usually live in 2 weeks. AI agents and chatbots take 30 days end-to-end, including data integration, prompt design and observability.
Do you work with companies outside France?+
Yes. Although most of our clients are French SMBs, we operate in English and ship for clients across Europe and North America. Infrastructure can be hosted in EU regions (GDPR-friendly) or in the cloud provider of your choice.
What does the ROI guarantee actually cover?+
Every engagement is anchored to a measurable outcome agreed in writing - hours saved per week, conversion rate uplift, time-to-quote reduction. If the outcome is not met within the agreed window, we continue to iterate at no extra cost until it is.
Can I combine several services in one project?+
Yes - most of our long-running engagements stack two or three services. A typical combo is a custom SaaS (front + back), automated CRM flows on n8n, and an AI agent for support or sales. We bill per scope, not per hour, so combinations stay predictable.
