About The Company
Kustomer is the industry-leading conversational CRM platform dedicated to enhancing every customer interaction. Designed with advanced intelligent tools such as artificial intelligence (AI) and automation, Kustomer provides a no-code configuration environment and a unified data platform that consolidates information from multiple sources into a single timeline. This enables businesses to operate more efficiently while delivering highly personalized and meaningful customer service across various communication channels. Renowned brands such as Sweetgreen, Starz, Vuori, Resy, and Cotopaxi rely on Kustomer’s platform to elevate their customer engagement strategies.
Founded in 2015 by serial entrepreneurs Brad Birnbaum and Jeremy Suriel, Kustomer has secured over $230 million in funding from leading venture capital firms. The company was acquired by Meta in 2020, completing the transaction in 2022, and subsequently integrated into Meta’s Business Messaging Group to revolutionize communication between people and businesses through modern messaging channels. In 2023, Kustomer spun out from Meta as an independent entity, backed by original investors including Battery Ventures, Redpoint Ventures, and Boldstart Ventures, with an additional $60 million investment. The company continued to grow with a $30 million Series B funding round in 2025 led by Norwest Venture Partners, emphasizing its commitment to expanding its AI-native platform, accelerating product innovation, and scaling its talented team. Kustomer’s culture is built on passion, collaboration, and a shared mission to improve the customer service experience, with a flexible, remote-friendly work environment across the U.S. and U.K.
