About

Prompt optimization, automated voice testing, monitoring, and more. Test your AI voice agent against 1000s of simulated users in minutes. AI voice agents are hard to get right. A small change in prompts, function call definitions or model providers can cause large changes in LLM outputs. We're the only end-to-end platform that supports you from development to production. You can store, manage, version, and keep your prompts synced with voice infra providers from Hamming. This is 1000x more efficient than testing your voice agents by hand. Use our prompt playground to test LLM outputs on a dataset of inputs. Our LLM judges the quality of generated outputs. Save 80% of manual prompt engineering effort. Go beyond passive monitoring. We actively track and score how users are using your AI app in production and flag cases that need your attention using LLM judges. Easily convert calls and traces into test cases and add them to your golden dataset.

About

Hermes is the operating platform for AI voice agencies. It replaces the Retell + GoHighLevel + Zapier + Stripe + Twilio + developer stack with one white-label platform agencies use to deploy, manage, and scale voice agents under their own brand. Built-in CRM, campaign orchestration, and transparent usage-based billing mean your clients never see the word Hermes. Launch your first agent in 72 hours and run 80%+ margins on every client you serve. Plans from $149/mo (3 workspaces, 300 included minutes) to $699/mo (20 workspaces, 2,000 minutes), with flat $0.24/min overage and a Contact Us tier for enterprise. Built by builders, for builders.
