Flatchr Tech Stack

Collaborative ATS for hiring teams, with manager-first workflows

Software Development Boulogne Billancourt, Ile de France 51–200 employees Founded 2015 Privately Held

Flatchr builds a recruitment platform designed around manager involvement rather than HR gatekeeping. The stack (React, Node.js, PostgreSQL on GCP) supports core ATS workflows: centralized candidate intake, multi-board job posting, interview scheduling, and evaluation feedback loops. Current hiring velocity is sales-led (3 open sales roles vs. 1 engineering), and recent project work on n8n automation between HubSpot, Slack, and Pennylane suggests Flatchr is moving toward workflow automation and financial integration—operational challenges that typically arise as sales scales and process debt accumulates.
