Overview

Guava is a voice AI platform for regulated industries, built by Gridspace, a company formed in Los Angeles in 2012 in collaboration with SRI Speech Labs, the lab behind Siri, with co-founder Anthony Scodary among its founding team. The company has since rebranded its product from Gridspace to Guava, with the original gridspace.com domain now redirecting to the new brand.

Guava's approach is to own its entire voice stack, speech recognition, language models, and speech synthesis, rather than assembling third-party APIs, which it positions as the reason it can hit sub-1-second latency at scale. The platform is built for healthcare, banking, insurance, and BPO calls that must meet compliance standards, with SOC 2 Type II, HITRUST i1, and PCI DSS Level 1 built into the product.

It targets engineering teams at regulated companies building voice agents for intake, prior authorization, collections, or identity verification calls, rather than teams wanting a no-code chatbot builder. Pricing is not publicly listed; the company points prospects to a demo and custom quote, consistent with its enterprise, compliance-heavy customer base.
