Construction invoicing platform for French contractors and self-employed

Software Development Nantes, Pays de la Loire 51–200 employees Founded 2019 Privately Held

Obat builds invoicing and project-management software for construction artisans and contractors in France. The tech stack reveals a deliberate modernization in progress: legacy PHP/Symfony monolith (MySQL, MongoDB) paired with contemporary frontend (React, TypeScript) and distributed backend patterns (microfrontends, BFF, monorepo). Active projects around n8n workflow automation and custom integrations (Python, Node.js) suggest the core product is shifting from pure billing toward operational workflow orchestration—addressing the pain point of reducing administrative time for field teams.

About Obat

Obat is a French SaaS platform founded in 2019 that provides invoicing, quote management, and project-tracking tools for construction businesses, from solo artisans to small contracting firms. The product is built on PHP/Symfony with a modern React frontend, deployed on AWS. Beyond invoicing mechanics, the platform integrates with accounting systems and jobsite management workflows. The current engineering-and-data-focused hiring mix (3 engineers, 2 data, 1 product across 51–200 employees) reflects an organizational phase centered on product scaling and internal tooling, not sales expansion. The company operates entirely within France.
