About Us


At PostCo, we’re building the decisional AI layer for commerce.


PostCo started in 2021 by tackling one of the ugliest problems in commerce: returns. This year, we expanded into a much bigger vision with the launch of Upsell and Order Editing. PostCo now goes beyond post-purchase into pre-purchase, covering the entire shopping journey from cart to return. Underneath it all is a shared intelligence layer that helps brands make better decisions at every step — what to sell, when to offer an exchange, and how to keep a customer.


We’re building a global product from Southeast Asia, proving that world-class software can be built from this region. We pivoted during the pandemic and became profitable in 2022. We don’t raise money from investors or venture capital firms - we’re ambitious builders and operators who sweat the smallest details and grow by building great, profitable products our users love.


Today, PostCo is used by hundreds of brands across the UK, Australia, and the EU, including Astrid & Miyu, Cole Buxton, and Creed. If you’re excited about building products used by hundreds of thousands of shoppers around the world every day, we’d love to work with you.
