Vapi bets voice-agent infrastructure, not apps: Ring pick, $500M
YC W21 pair pivots Superpowered into Vapi, a voice-agent API; 1B+ calls later, Amazon Ring routes all inbound through it.
Vapi
What the business is
A voice-AI platform giving developers APIs to build, deploy and manage voice agents for customer support, sales, scheduling and outreach.
Starting capital：$2.1M seed (Kleiner Perkins, Abstract Ventures) by Nov 2023; $50M Series B (May 2026) brings total to $72M.
How it started
University of Waterloo classmates Jordan Dearsley and Nikhil Gupta founded Superpowered in 2020, an AI meeting notetaker that went through YC W21 and became profitable. In 2023 Dearsley built a voice AI he talked to on walks; few wanted the therapy product, but startups wanted the voice infrastructure behind it.
What happened
In Nov 2023 they pivoted Superpowered to Vapi, launching phone and web APIs built on Twilio, Deepgram, Daily, OpenAI and PlayHT, with $2.1M raised. Self-serve developer adoption came first: by May 2026 Vapi had handled 1B+ calls and signed Amazon Ring, Kavak, Instawork, New York Life and Intuit. A $50M Series B led by Peak XV Partners at ~$500M valuation brought total funding to $72M, with ~100 employees.
How it ended up
Scaling: $50M Series B at ~$500M (May 2026); Ring routes 100% of inbound calls through Vapi; expanding engineering, infrastructure and go-to-market teams.
Background
Vapi is a voice-AI platform that gives developers APIs to build, deploy and manage AI voice agents for customer support, sales, scheduling and outreach. Its bet is that the low-latency voice infrastructure behind AI agents — not pre-packaged applications — is what developers and enterprises will pay for, and that a self-serve developer base can become the wedge into large enterprise deals.
University of Waterloo classmates Jordan Dearsley and Nikhil Gupta founded Superpowered in 2020, an AI meeting notetaker that went through Y Combinator's Winter 2021 batch and became profitable. In 2023 Dearsley built a voice AI he talked to on walks; few wanted the therapy product, but startups kept asking for the voice layer underneath. In November 2023 they pivoted to Vapi, launching phone and web APIs built on Twilio, Deepgram, Daily, OpenAI and PlayHT, backed by $2.1M from Kleiner Perkins and others.
Self-serve adoption came first — more than 1 million developers used the platform, which Vapi says made it battle-tested before its first major enterprise contract. By May 2026 it had handled over 1 billion calls, signed Amazon Ring, Kavak, Instawork, New York Life and Intuit, and closed a $50M Series B led by Peak XV Partners at roughly a $500M valuation, bringing total funding to $72M. Ring now routes 100% of its inbound calls through Vapi after evaluating more than 40 AI voice vendors.
What has to be true
- Dearsley and Gupta saw startups asking for low-latency voice infrastructure before they had any enterprise sales motion — the API was the wedge, not a single use case.
- Self-serve distribution (1M+ developers) made Vapi battle-tested at scale before its first big enterprise deal, which is how it beat 40 vendors for Amazon Ring.
- Focusing on infrastructure and orchestration rather than pre-packaged apps let enterprises control reliability, compliance and model behavior.
- The voice market's growth (Ring, Intuit, Kavak) turned a developer tool into an eight-figure-ARR infrastructure bet.
What can be applied
A product nobody wants can still hide a business: the therapy app flopped, but its underlying voice infra became the API enterprises paid for — pivot toward the thing others keep asking for.
Aftermath
As of September 2026 Vapi is private with ~100 employees, processing 1M–5M calls a day, and using the Series B to grow engineering, infrastructure and go-to-market teams; Amazon Ring routes 100% of its inbound calls through the platform.
