Voice AI for the hard use cases.
If you're looking to improve performance and reduce costs for your production calls, we're here to help. Our team includes Stanford AI Lab and Y Combinator alumni, and we'd be glad to bend the ThunderPhone stack to your needs.
Customization and implementation.
Our integrated stack lets us tune the full call loop around your needs.
Platform customization
Custom call flows, integrations, routing, deployment patterns, compliance controls, and operating workflows built on top of ThunderPhone.
Hands-on implementation
We'll help you design, build, test, launch, and tune your voice agents when you want the outcome delivered, not just the tools.
Price-critical optimization
For high-volume use cases including but not limited to outbound with long hold times, voicemail, and screeners, we can reach 1¢/min or less.
Compliance, residency, SLAs — when you need them.
HIPAA and GDPR are ready out of the box. For larger deployments, we scope the security, legal, and operating package around your requirements.
Special use cases.
Because ThunderPhone owns the full call loop, optimization isn't limited to one modular component — we can add fine-tuning, custom guardrails, lower-cost routing, and specialized integrations. Reach out to learn more.
Bring your own LLM
Use ThunderSocket to connect your own model while ThunderPhone handles telephony, speech, turn-taking, testing, and production call operations.
ThunderHuman
Cold outbound that stays TCPA-compliant: vetted human agents handle each call, saying only what the AI tells them to say. Just as easy to set up and change prompts/integrations as ThunderPhone, but fully TCPA compliant.
Flux Interpreting
Over-the-phone interpreting (OPI) built for language service providers — powered by ThunderPhone AI. Interpret between any two languages ThunderPhone supports.
