Gridspace

Gridspace is a voice AI company (founded 2013) that now operates as Guava (goguava.ai) — a voice agent platform built for regulated industries such as healthcare, banking, insurance, BPOs, and government. Guava provides an end-to-end conversational voice stack (ASR, LLM, TTS, plus compliance guardrails) exposed through Python, TypeScript, and Elixir SDKs, a "guava" CLI, a managed cloud deployment platform, and a REST API for managing conversations, transcripts, recordings, and SMS. It supports inbound and outbound calling over WebRTC and SIP, with SOC 2 Type II, HITRUST i1, and PCI DSS posture and built-in TCPA / A2P 10DLC / SHAKEN-STIR telephony compliance workflows. The legacy gridspace.com domain now redirects to goguava.ai.

Gridspace publishes 3 APIs on the APIs.io network: Conversations API, Messages API, and SDK API. Tagged areas include Company, Voice AI, Conversational AI, Voice Agents, and Speech Recognition.

Gridspace’s developer surface includes documentation, API reference, getting-started guide, signup flow, pricing, engineering blog, support, and 31 more developer resources.
