SAN FRANCISCO, CA, May 13, 2026 – Vapi raised $50 million in series B funding to expand its voice AI infrastructure for business phone calls, as enterprises push beyond fixed phone trees and scripted support systems. The round, led by Peak XV with participation from M12, Microsoft’s Venture Fund, Kleiner Perkins and Bessemer Venture Partners, followed 10x enterprise ARR growth and brings Vapi’s total funding to $72 million.
The company builds configurable voice agents for customer and business calls. Its software is used where callers need issue resolution, routing or task completion without relying only on static phone menus or rule-based scripts.
Vapi projected that nearly $3 trillion in global sales could be at risk in 2026 due to poor customer experiences. It also cited customer satisfaction data showing no improvement since 2017 and a 2% decline since 2022, despite investment in chatbots, automation and self-service portals.
Enterprise customers include Amazon Ring, Kavak, ServiceTitan, New York Life and Intuit. Amazon Ring uses Vapi to handle inbound customer inquiries about smart home security devices.
“When [Amazon] Ring customers call in, they expect fast, high-quality support,” said Jason Mitura, Vice President of Software Development at Amazon Ring. “After evaluating dozens of vendors, Vapi stood out. We went from zero to production in two weeks, and 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. A lot of AI tools promise great outcomes – Vapi has delivered on them.”
Vapi supports inbound customer service, outbound collections, candidate screening, sales coaching through simulated dialogue and autonomous IVR navigation. Customers also use the platform to support contact centers, automate high-volume qualification workflows and manage third-party payer processes without human involvement.
The software is optimized for low-latency voice interactions and lets teams switch models and providers. Its API reduces the need for developers to work with telephony internals and supports movement from prototype development to production deployment in days rather than months.
“Vapi has built a differentiated self-serve product for developers and enterprises in the massive voiceAI revolution,” said Arnav Sahu, Partner at Peak XV. “In 10 years, it’s likely most calls will not have a human behind the phone. With its bottom-up, PLG approach, we believe Vapi is the next Zapier and n8n for voiceAI workflows. At Peak XV, we are investors in several developer and bottom-up companies like Supabase, PostHog, Better Auth and ClickHouse and believe Vapi has the potential to be the defining platform for voice AI. We are excited to partner with them.”
Co-founders Jordan Dearsley and Nikhil Gupta met at the University of Waterloo and built products together, including a Y Combinator-backed calendar app. Vapi’s infrastructure grew from a voice-based AI therapist prototype that Dearsley built in mid-2023 by chaining models together and optimizing for latency. The therapy product did not gain traction, but the phone-based system led to Vapi’s public launch on Product Hunt in March 2024.
Most businesses have spent decades of time and effort, only to make their customer experience worse,” said Jordan Dearsley, CEO and co-founder of Vapi. “The real unlock is building agents for your customers that feel human. Vapi gives teams the platform to deploy voice agents that actually solve problems for customers – millions of them, every day.
Vapi is focusing on governance and predictable operation as voice agents move into higher-stakes workflows. The company is working on uptime guarantees, stable latency under load, call-level monitoring, guardrails that keep agents within defined limits and escalation paths for cases that require human support. Its strongest traction is in financial services, health care, insurance, automotive and workforce management.
