Guava

An insurance caller asking for a claim status, a patient confirming an appointment, a borrower in collections: Guava says these are the calls its software is meant to handle. The company sells a voice agent API, with Python and TypeScript SDKs, aimed at teams that need a phone agent working in days rather than months, and it promises a production agent in ten minutes of setup.

Prompt bloat is a maintenance nightmare

Its home page argues against long system prompts, where every fix adds another rule and old calls can regress. Instead it offers code in place of prompts: rules written as versioned, tested and reviewed code, and a command line tool that scaffolds, runs and deploys an agent. A blog post on its API design explains a terse approach where a task is set with a checklist. The team also writes comparison posts about building on stitched third-party voice services versus owning the full stack.

One stack, end to end

Guava states that it built its own hearing, turn-taking and speaking components, trained on real calls, with no other vendor stitched in. The customer's code and systems stay in charge of the logic and records. Industry pages cover BPO, healthcare, vertical AI software, insurance, fintech, government and others, with examples such as healthcare intake, bank KYC, collections and legal intake.

Certified for regulated calls

The site lists SOC 2 Type II, HITRUST i1 and PCI DSS Level 1, with a business associate agreement available for healthcare, and says the stack has run in regulated production for 13 years. Figures on the page include more than 10 billion live agent minutes, more than 100 regulated deployments and a 99.9 percent uptime target. A banner on its pages says the company raised 12.5 million dollars, and links to a press release; the pages do not say who led the round.
