OnBuy is a British online marketplace founded in 2016 and headquartered in London. It does not hold its own inventory; instead it gives independent retailers a selling platform to reach consumers, so it never competes with its sellers. Shoppers earn cashback rewards on purchases. The privately held company employs 51–200 people and currently hires in the United Kingdom. Its product footprint spans buyer-facing web storefronts, seller tooling and marketing channels such as Google Shopping and Bing.
OnBuy uses PHP and Laravel with React, Vue and Angular, data stores like MySQL, MongoDB and Couchbase, and runs on GCP with Kubernetes, Docker, Helm, Terraform and GitLab CI/CD. Data tooling includes BigQuery, Snowflake, Airflow and Fivetran.
OnBuy is moving from legacy architecture to a modern composable platform while keeping live operations resilient. Finance is building a budgeting and scenario-planning model and implementing FP&A software alongside NetSuite.
