Every inbound customer inquiry about its smart home security devices now runs through a Vapi-powered agent, and customer satisfaction scores have improved since the switch. "After evaluating dozens of vendors, Vapi stood out," said Jason Mitura, Vice President of Software Development at Amazon Ring. "100% of our inbound volume now runs through the Vapi. Most importantly, we've maintained our high bar of support for our customers and CSAT scores have improved. Vapi gives our teams the ability to tune the agent experience without depending on engineering." That result sits behind a funding round announced today. Vapi has raised $50 million in Series B financing led by Peak XV, with participation from M12 (Microsoft's venture fund), Kleiner Perkins, Bessemer Venture Partners and earlier backers. Total funding stands at $72 million. ## How Vapi AI Voice Agents Work at Enterprise Scale Vapi is an API-first platform for building, deploying and managing voice AI agents. Engineering teams use it to handle inbound customer service, outbound collections, candidate screening and automated call routing without needing to understand telephony internals. In a market where [enterprise software is being reshaped by AI](https://www.sovereignmagazine.com/article/how-salesforce-s-60-billion-ai-bet-is-reshaping-the-enterprise-software-landscape), Vapi's bet is that voice is the interface most in need of rebuilding. The platform is model-agnostic, meaning customers can swap language models and voice providers without rebuilding their integration, and supports sub-500-millisecond response times. The company reports more than one million developers on its platform, 2.7 million unique agents created and over one billion calls completed. Annual recurring revenue has grown tenfold in the enterprise segment, though Vapi has not disclosed absolute revenue figures. ## Enterprise Customers Using Vapi for Voice AI Amazon Ring is the most prominent name on Vapi's client list, but it is not alone. New York Life, Intuit, Kavak, Instawork, UnityAI and Cherry also use the platform. Deployments span financial services, healthcare, insurance, automotive and workforce management. The pattern across these accounts is speed to production and operational independence from engineering teams. Mitura noted that Ring's staff can tune the agent experience without filing engineering tickets. For enterprises accustomed to months-long integration cycles with contact center vendors, that represents a practical change in how voice channels are managed. ## Why Voice AI Startups Are Raising Large Rounds in 2026 Vapi is not the only voice AI company attracting capital. [Agentic AI startups across sectors are raising](https://www.sovereignmagazine.com/article/zalos-agentic-ai-finance-seed-round) at a rapid pace. Bland AI raised a $40 million Series B in January 2025, bringing its total to $65 million. Synthflow closed a $20 million Series A led by Accel. Retell AI, which has disclosed only $5.1 million in funding, claims $50 million in annual recurring revenue. The investment case rests on a straightforward cost gap. Voice AI agents cost roughly $0.40 per call, compared with $7 to $12 for a human agent. Gartner forecasts that conversational AI will reduce contact center labor costs by $80 billion in 2026. The broader voice AI agents market, valued at $2.4 billion in 2024, is projected to reach $47.5 billion by 2034. Customer satisfaction, meanwhile, has stalled. The American Customer Satisfaction Index has not exceeded its 2017 level despite years of corporate investment in [chatbots, automation and self-service portals](https://www.sovereignmagazine.com/article/ai-driven-chatbots-redefine-customer-experience-and-conversion-in-ecommerce-2). Qualtrics estimates that $3.1 trillion in global consumer sales are at risk annually from poor customer experiences. Vapi's pitch is that voice, not text, is where customer intent is highest and where AI-powered automation can deliver the largest improvement. ## Peak XV Leads Vapi AI Series B Funding Round The round's lead investor, Peak XV (formerly Sequoia India and Southeast Asia), has been assembling a US-focused developer tools portfolio. Partner Arnav Sahu, who previously ran growth investments at Y Combinator's Continuity fund, joined Peak XV as its first US-based investment partner in 2025. His other bets include PostHog, Supabase and Better Auth. "Vapi has built a differentiated self-serve product for developers and enterprises in the massive voice AI revolution," Sahu said. "In 10 years, it's likely most calls will not have a human behind the phone. We believe Vapi is the next Zapier and n8n for voice AI workflows." M12's participation adds a strategic dimension. Microsoft is OpenAI's exclusive cloud partner, and many of Vapi's deployments use OpenAI's models. Kleiner Perkins, which led Vapi's $2.1 million seed round in November 2023, and Bessemer Venture Partners, which led the $20 million Series A in December 2024, both followed on. ## How Vapi AI Went From a YC Startup to a Voice AI Platform The company's path to a $72 million war chest was not direct. Co-founders Jordan Dearsley and Nikhil Gupta met at the University of Waterloo and entered [Y Combinator's Winter 2021 batch](https://www.sovereignmagazine.com/article/auctor-20m-sequoia-system-integrators) with a video lecture platform for professors. They pivoted during the program to a calendar app that reached profitability, then pivoted again to an AI meeting notetaker. In mid-2023, Dearsley built a voice-based AI therapist as a personal project, chaining language models together and optimizing for latency until he had a working phone system. The therapy product did not gain traction. The infrastructure behind it did. Vapi launched publicly on Product Hunt in March 2024 and has since grown from roughly 100,000 developers to over one million. "Most businesses have spent decades of time and effort, only to make their customer experience worse," Dearsley said. "Vapi gives teams the platform to deploy voice agents that actually solve problems for customers." ## What Comes Next for Vapi AI Voice Agents The company says its next priority is governance and predictability. As voice agents take on higher-stakes workflows in financial services and healthcare, Vapi is investing in uptime guarantees, latency controls under load and call-level monitoring that treats every conversation as a production workload. It is also building what it describes as self-improving agents that learn from real conversations to increase resolution rates while staying within compliance boundaries. **About Vapi** API-first platform for building, deploying and managing voice AI agents at enterprise scale.

[Website](https://vapi.ai) ## FAQ **Q: How does Vapi AI work?** Vapi provides an API that lets engineering teams build, deploy and manage voice AI agents without understanding telephony internals. The platform handles transcription, language model orchestration, text-to-speech and telephony infrastructure in a single layer, supporting sub-500-millisecond response times. **Q: Is Vapi AI free or paid?** Vapi operates on a usage-based pricing model. Developers can start building on the platform for free, but production deployments incur per-call charges. The company has not publicly disclosed detailed pricing tiers. **Q: Which is better, Vapi or Retell AI?** Both are voice AI platforms with different market positions. Vapi is API-first infrastructure aimed at enterprise engineering teams, while Retell AI offers a pay-as-you-go model with both developer SDK and no-code options for mid-market customers. Amazon Ring, New York Life and Intuit are among Vapi's disclosed enterprise clients. **Q: What is the open-source alternative to Vapi?** Open-source voice AI frameworks include LiveKit, Pipecat and Vocode. These offer more control over the infrastructure stack but require teams to manage telephony, model orchestration and latency optimization independently. Vapi's value proposition is that it handles this complexity as a managed service.
