AI voice startup Vapi raised $50M in Series B funding at a $500M valuation after Amazon selected it to handle 100% of Ring customer support calls, beating over 40 competitors.
Peak XV led the funding round for Vapi, an AI voice platform that automates customer support and sales calls for enterprises.
Amazon Ring's decision to consolidate its call handling with Vapi followed an evaluation of more than 40 AI voice vendors. The e-commerce giant faced a surge in customer-support inquiries during the 2024 holiday season, prompting the search for a scalable AI solution.
Vapi's enterprise business has expanded tenfold since early 2025, reflecting broader industry momentum toward AI-powered customer service. Companies are increasingly replacing human agents with AI voice systems for routine interactions, cost reduction, and 24/7 availability.
The startup's selection by Amazon—a major validation from one of the world's largest tech companies—signals growing confidence in Vapi's technology and reliability at scale. Handling 100% of Ring's inbound calls represents a significant production deployment for an AI voice platform.
Vapi competes in a crowded market that includes established players and well-funded startups developing conversational AI for enterprise use. The space has attracted substantial investment as businesses seek to optimize customer contact centers and reduce operational expenses.
The $500M valuation reflects investor confidence in the AI voice market's expansion, though the startup remains in a competitive landscape where technical performance and customer reliability are critical differentiators. Peak XV's participation underscores interest from leading Asia-focused venture firms in AI infrastructure plays.
Vapi's funding brings capital for product development, infrastructure scaling, and sales expansion as it pursues additional enterprise customers beyond Ring.
