UJET, a San Francisco-based company that sells AI-powered contact center technology, has acquired Spiral, a Seattle startup that helps businesses analyze customer conversations. Terms of the deal were not disclosed.

Spiral will operate as “Spiral by UJET,” continuing to support its customers as a standalone offering while also integrating into UJET’s cloud contact center platform.

Founded in 2018 by former Amazon engineers Elena Zhizhimontova and Andrew DiLosa, Spiral uses AI to automatically detect and categorize issues raised across phone calls, chats, emails, surveys and social media. The technology is designed to help companies uncover product and support problems. Customers include Owlet, Whitepages and Turo.

“UJET’s acquisition of Spiral will provide businesses with a unified view of all customer conversations for more proactive, personalized service,” UJET CEO Vasili Triant said in a statement.

Spiral previously raised nearly $7 million from investors including Trilogy Equity Partners, Bezos Expeditions, Techstars, Alumni Ventures Group, Ensemble, and the Alexa Fund. The startup has less than 10 employees — all will join UJET, including Zhizhimontova, now vice president of applied AI. The company competes in a growing category of startups applying AI to customer feedback.
