EasyPost
EasyPost is a Utah-based logistics technology company that built the first RESTful shipping API, giving developers a single integration point to rate-shop, buy and print labels, verify addresses, track packages and insure shipments across 100+ carriers worldwide. Founded in 2012 by Jarrett Streebin, it removes the technical complexity of shipping so e-commerce brands, marketplaces and fulfillment providers can ship like Amazon without rebuilding carrier plumbing from scratch.
