Leaping AI is a YC W25 voice AI platform founded in 2023 by Kevin Wu, Arkadiy Telegin and Shraey Bhatia, originally in Germany before relocating to San Francisco. Its voice agents handle high-volume, repetitive calls such as scheduling, billing and lead qualification in 10+ languages with under two-second latency and self-improving QA. For one retailer, Leaping AI's voice agents handle 100% of incoming support calls and automate up to 70% end to end. The company raised a $4.7M seed round led by Nexus Venture Partners with Y Combinator and Paul Graham participating, closing in under a week.
