We Are Route When shoppers hit "buy," a great customer experience doesn’t end, it’s just getting started.

That's why we built Route. Our mission is simple: we create shopper confidence that fuels brand growth. Route is the leading post-purchase platform for modern ecommerce, trusted by over 13,000 brands and protecting more than $20 billion in gross merchandise value to date. From package protection and industry-leading order tracking to returns and exchanges, cash back loyalty, and engaging product recommendations, Route brings every moment after checkout into one powerful platform, empowering shoppers with visibility and peace of mind while giving merchants loyalty that lasts well beyond the first sale. Since launching in 2018, Route has raised over $250 million from leading investors including Craft Ventures, Hedosophia, and Hanaco Ventures, and has grown into a complete post-purchase ecosystem loved by millions of shoppers and the brands they buy from. Throughout that growth, we've stayed committed to building innovative products that empower our customers and to fostering a people-first, values-driven culture that makes Route a place where great work and great people thrive.
