Braze, Inc.
A maker of customer-engagement software, Braze helps brands like Spotify, Sephora, and Dominos send personalized messages in real time across email, push notifications, in-app, and ads. Founded in New York in 2011 by three hackers who met at a hackathon, it started life as Appboy before rebranding to Braze in 2017. The name comes from a metalworking term for joining pieces together at high heat — a fitting metaphor for connecting brands with their customers.
