Software Development San Francisco, CA 201–500 employees Founded 2019 Privately Held

Extend runs a post-purchase operations platform covering returns, exchanges, shipping and product protection for ecommerce merchants on Shopify, BigCommerce and SuiteCommerce. Data is the largest hiring function, and a stack of PyTorch, XGBoost, scikit-learn and TensorFlow on Snowflake and dbt points to ML-driven claim and risk scoring, with Gemini now being adopted. Finance-side projects around invoice reconciliation and automated tie-outs signal back-office scaling pains.
