FAQ
Common Questions
Who is eligible for this offer?
This offer is for members of the Claude Startups Program applying for their own startup, rather than an agency or another kind of business. Your team must never have had a paid Retell AI account or redeemed a previous Retell AI offer.
What does the offer include?
20% off your Retell AI usage for your first six months, with no cap on total savings. The discount applies to usage with any model Retell AI supports, including Claude. After six months, you move to standard pay-as-you-go pricing.
How do I redeem the offer?
Create your Retell AI account, copy your Workspace ID from Settings → Workspace → General, and fill out the application form above. We verify eligibility and email you within two business days. Once approved, the discount applies automatically to your usage.
Where do I find my Workspace ID?
Log in to Retell AI and go to Settings → Workspace → General. Your Workspace ID is listed there.
How do Retell AI voice agents work?
Retell AI is a real-time conversational AI platform that uses proprietary voice AI orchestration with low-latency speech recognition, LLM-powered conversation understanding, and real-time function calling. The platform features ~600ms latency, ultra-realistic voices built from real performance data, and proprietary turn-taking models that know when to speak and listen.
What can a Retell AI voice agent do on a call?
It answers inbound calls and places outbound ones, qualifies leads, books appointments, checks order status, and routes or transfers to a live agent when needed. Mid-call, it can pull and push data through your existing systems, so it acts on real customer information rather than reading from a script.
Can I connect an agent to my existing phone number?
Yes. Retell supports integration with any telephony system through SIP trunking, making it easy to connect your existing phone number without changing infrastructure.
