Guava raises $12.5M seed led by Acrew Capital for voice agent tools

Acrew Capital led the seed, with Flourish Ventures, WillowTree Ventures, Clocktower Ventures and existing investor Commerce Ventures participating. Guava builds tools that let software engineers create and run AI voice agents, which handle phone conversations that companies would otherwise staff by hand.

Its customers come mainly from insurance and financial services, where firms want automated calls while keeping control of their business rules. The company will put the money into product development, AI model research and commercial expansion, according to the announcement summarized in the roundup.

For founders, the round signals that the infrastructure layer for voice agents, covering call control, compliance and model routing, is drawing seed capital before the application layer matures. Teams in voice should expect rivals to compete on reliability and governance rather than on demos.
