Amperity

Amperity is a Seattle-based enterprise software company that builds an AI-powered customer data platform. Its patented machine-learning identity resolution engine, Stitch, unifies fragmented customer records from disparate sources - email, phone, address, loyalty and device IDs - into a single, accurate view of each customer. Founded in 2016 by Kabir Shahani and Derek Slager, Amperity helps global consumer brands like Alaska Airlines, DICK'S Sporting Goods, and Wyndham turn messy data into reliable profiles, predictive insights, and activation across marketing, analytics, and AI. The company reached unicorn status in 2021 with a $100M Series D and has since pivoted toward an AI-first, lakehouse-native architecture that runs directly inside Databricks and Snowflake.
