But most phone experiences still run on rigid phone trees, scripts, and deterministic systems that can’t listen, adapt, or resolve issues the way a human can.

Voice is where intent is highest and expectations are clearest. Vapi, the leading platform for deploying configurable voice agents at scale, was built to make that channel extraordinary.

Following a 10x in enterprise ARR growth, the Series B round was led by Peak XV with participation by M12, Microsoft’s Venture Fund, Kleiner Perkins, Bessemer Venture Partners, and earlier investors, bringing total funding to $72 million.

Nearly $3 trillion in global sales are projected to be at risk in 2026 due to bad customer experiences. And despite years of investment in chatbots, automation, and self-service portals, customer satisfaction scores haven’t increased. Since 2022, they’ve actually dropped by 2%, and haven’t meaningfully moved since 2017.

The problem isn’t that businesses aren’t trying. It’s that the systems behind most customer interactions were never designed to listen, adapt, or meet people where they are. Vapi believes the fastest way to earn trust and resolve issues has always been a real conversation. Voice AI can finally make those conversations happen at scale.

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 is an enterprise voice AI platform for building, deploying, and managing voice agents that deliver the outcomes businesses want at the scale their customers need.

The platform is designed to take teams from working prototype to production-scale deployment in days instead of months.

Vapi’s platform is optimized for low latency, with the flexibility to swap models and providers, and an API that removes the need to understand telephony internals.

Vapi’s mission is to make it easy for any business to build the kind of human interface that lets customers get the help they need.

The platform powers voice AI for businesses that need to handle calls at scale – supporting everything from inbound customer service and outbound collections to candidate screening, sales coaching through simulated dialogue, and autonomous IVR navigation.

Customers use Vapi to replace or augment contact centers, automate high-volume qualification workflows, and navigate complex third-party payer systems without human involvement.

The company has found its strongest traction in financial services, healthcare, insurance, automotive, and workforce management.

“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 spent years building products together, including a Y Combinator-backed calendar app that reached profitability.

Vapi started almost by accident. In mid-2023, Dearsley built a voice-based AI therapist for his daily walks, chaining models together and optimizing for latency until he had a working phone-based system.

The therapy product didn’t take off, but the infrastructure did. Vapi launched publicly 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.

Today, the company reports more than 1 million developers, over 2.7 million unique agents created, and over 1 billion calls made.

Vapi sees the next phase of voice AI being defined by governance and predictability. As agents take on higher-stakes workflows, enterprise operators need tighter uptime guarantees, predictable latency under load, and call-level monitoring that treats every conversation as a production workload. That is where the company is focused: deeper reliability, stronger guardrails that keep agents within defined boundaries, and clear escalation paths when a situation calls for a human.

The goal is to make it easy for any business to deploy voice agents that deliver measurable outcomes at scale, so that getting help feels as natural as having a real conversation.

This advancement, coupled with the accessibility of voice models on consumer mobile devices, has spurred growing interest among enterprises aiming to automate business-to-customer interactions. 

However, deploying and scaling voice agents can require months, if not years, of specialized engineering.

Helping enterprises overcome this challenge, Vapi, a developer platform for deploying Voice AI agents, has raised $20 million in Series A funding, led by Bessemer Venture Partners with participation from Abstract Ventures, AI Grant, Y Combinator, Saga Ventures, and Michael Ovitz. 

This investment will enable the company to expand its engineering team, scale its infrastructure, and reach new enterprise customers.

Founded in 2023 by Jordan Dearsley (CEO) and Nikhil Gupta (CTO), Vapi is on a mission to “bend the arc of technology back to the human voice,” Vapi is building the infrastructure necessary to enable this voice-first future. 

Through its flexible API and developer platform, customers can scale to handle millions of calls using voice agents in a couple of weeks.

Recognizing that every business has its own unique workflows and integrations, Vapi takes a developer-first approach. It provides APIs for engineering teams to design custom conversation flows, integrate their CRMs and EHRs, and incorporate Vapi’s voice agents into existing enterprise telephony systems.

Jordan Dearsley, CEO of Vapi commented: “Consumer-facing companies run on voice. To scale their revenue, they need to scale their voice operations. But, people don’t scale. You can try using an IVR (interactive-voice responses) system, but they sound robotic, and people just smash zero until they can talk to a person. With generative voice models, it’s flexible like a human and it can scale to millions of calls.”

Since its launch, Vapi has experienced remarkable growth, scaling to millions in revenue within its first six months. 

The company has partnered with businesses across various industries—including finance, healthcare, and travel—demonstrating the versatility and effectiveness of its voice AI technology. A few of Vapi’s customers include Mindtickle, Luma Health, Ellipsis Health, and Gestionadora de Créditos.

“Apple Intelligence and Google Gemini are poised to onboard 4 billion people to voice assistants that truly converse like humans. This marks a new beginning for voice as the world’s default interface. Consumers will want voice agents everywhere, and enterprises need a platform to deploy them. This funding will allow us to scale our team and infrastructure to meet the growing demand for AI voice agents” added Jordan Dearsley. 

“We chose Vapi to power our Voice AI strategy because of its mature platform and outstanding capabilities. It enables seamless integration, helping us deliver solutions to our customers in record time. Vapi is far ahead of any other platform—simple, powerful, and it just works.” Said Marcelo Oliveira, SVP of Engineering at Luma Health

“Vapi is emerging as the leading developer platform for conversational voice agents, helping enterprises deploy agents that solve their unique business problems without having to worry about managing the underlying models and infrastructure,” said Mike Droesch, partner at Bessemer Venture Partners. 

“We are impressed with their outstanding developer love, rapid growth, and focus on building a world-class product. We look forward to helping them continue to redefine how people interact with technology.”

“Just as developer platforms helped power the meteoric rise of cloud software over the past decade, we are thrilled to be partnering with Vapi as they help to usher in the next wave of conversational AI applications,” said Byron Deeter, partner at Bessemer Venture Partners. 

“We believe that AI will fundamentally impact every vertical of the economy, with voice agents becoming a core interface for many of these applications.”
