Pango

Pango is an agentic operating system for e-commerce back-office operations. Founded in Stockholm in 2025 by Steve Rahimi and Lukasz Reszczynski, it connects a merchant's store, warehouse and carriers, then runs deliveries, tracking, returns, refunds and claims on autopilot. The company says it automates roughly 99% of returns and shipping operations and cuts operating costs by about 20%, and is part of Y Combinator's Summer 2026 batch.
