Who are we?

Cernel is an e-commerce automation startup founded in 2023. We are a team of 12 people, actively hiring and expanding the team to support our growth. Cernel is building the next foundational layer for modern ecommerce systems. Today, businesses run on complex stacks of ERP, CRM, PIM, and WMS systems that rarely play well together.

We have already demonstrated traction with 30+ paying customers, and we're growing rapidly. Our first product – PIM ON AUTOPILOT – automates product data enrichment, filter construction, and categorization in existing PIM systems. But this is just the beginning: Our long-term goal is to evolve this into a fully agentic PIM system and eventually into an integration layer beneath all commerce software.

We are VC-funded, backed by private funds and founders/employees from team.blue, Humio and Google as well as a list of experienced e-commerce specialists. You will therefore work in a highly technical and skilled environment with an automation-first approach to solving complex problems.
