Each week, we surface promising startups & founders through data signals.
This week, we're spotlighting voice agents →
Voice Agents take the call
Amazon Ring tested more than 40 voice vendors in Q1. Every inbound call now routes through Vapi.
Voice AI now sits in two layers, and only the lower one still has venture upside. The infra layer is already consolidated and priced in. Vapi reached a $500M valuation on May 12, while Sierra trades at $15.8B and ElevenLabs at $11B.
The exciting opportunities now lie at the seed stages, where startups are now absorbing roles that once required a phone, a script, and a full payroll line.
