Lengow Tech Stack

Feed management and price intelligence platform for global e-commerce sellers

Software Development Nantes 51–200 employees Founded 2009 Privately Held

Lengow operates a feed management and pricing intelligence platform serving 3,600+ merchants across 60 countries. The tech stack reveals a dual-layer architecture: legacy PHP/Symfony alongside modern Python/Django/FastAPI, with PostgreSQL and MongoDB handling structured and unstructured data at scale. Active adoption of dbt, Apache Airflow, and Cube.js signals a shift toward self-service analytics and automated data pipelines—critical for addressing their stated pain points around real-time data processing, manual dashboard interventions, and data tool modernization. Hiring velocity is accelerating, with sales roles leading (13 open) and a heavy tilt toward senior hires, suggesting both customer expansion and organizational restructuring.
