Both claim $0.03/min. Only one has no catch.
RevRing requires a 10,000 minute bulk purchase ($300 minimum).
Burki has zero minimums.
You must purchase 10,000 minutes before making a single call. That's $300 committed before you even test.
If you only need 500 minutes/month, it takes 20 months to use your purchase. That's capital tied up.
Use 1 minute or 1 million. Same $0.03/min rate. Pay only for what you use, when you use it.

Common questions about Burki vs RevRing pricing and bulk minimums.
While both advertise $0.03 per minute, there's a crucial difference: RevRing requires purchasing bulk minutes upfront with a 10,000 minute minimum ($300 minimum spend). Burki offers true pay-as-you-go pricing - use 1 minute or 1 million minutes at the same $0.03/min rate with no bulk purchase required. For startups and teams with variable usage, Burki eliminates the upfront commitment risk.
RevRing requires a minimum purchase of 10,000 minutes, meaning you must commit $300 upfront before making a single call. If you don't use all those minutes, you've lost money. Burki has no minimum requirements whatsoever. Start with 200 free minutes (no credit card required), then pay $0.03 for exactly what you use - whether that's 100 minutes or 100,000 minutes per month.
RevRing's 10,000 minute minimum ($300 upfront) creates a significant barrier for small teams and startups who can't predict their usage. Burki is specifically designed to be startup-friendly: get 200 free minutes to test with no credit card required, then pay only for actual usage with no minimums. Scale from prototype to production without upfront commitments.
Burki delivers faster performance with 0.8s average response latency compared to RevRing's approximately 1.5s. This nearly 50% improvement in response time creates more natural conversations. Combined with Burki's true pay-as-you-go model (no bulk minimums), you get both better performance and better pricing flexibility.
No, RevRing does not offer a BYO (Bring Your Own) API keys option. With Burki's BYO mode, you can use your own API keys for LLMs (OpenAI, Anthropic), TTS (ElevenLabs, Deepgram), STT, and telephony providers (Twilio, Telnyx). You pay providers directly at their rates and only pay Burki the $0.03/min platform fee.
Burki includes several features not available in RevRing: IVR Explorer automatically maps existing phone trees into AI assistants; Voice Analyzer provides free post-call analytics; a three-tier memory system (semantic, episodic, procedural) for context retention; AWS Lambda auto-discovery for instant tool setup; BYO mode for using your own API keys; and AI-powered spam detection. All included at no extra cost.
