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.

Key features

Pros & cons

Pros

  • Full-stack voice ownership avoids latency and reliability issues of stacked third-party APIs
  • Compliance certifications fit regulated-industry procurement requirements out of the box
  • Long operating history (as Gridspace, since 2012) predating the current wave of voice AI startups
  • Code-first integration model suits engineering teams wanting control over dialog logic

Cons

  • Recent rebrand from Gridspace to Guava may confuse buyers researching the older name
  • No public pricing; the site directs prospects to book a demo
  • Code-based integration requires more engineering effort than no-code voice-agent builders
  • Regulated-industry focus makes it a heavier lift to adopt for simpler, low-compliance use cases
