AI dialer and sales engagement platform for B2B teams
Multi-line parallel dialing and single-line flow dialing with AI that filters out voicemail and phone trees to connect reps to live prospects faster.
Sequence outreach across phone, email, video, text and social from a single sales engagement workflow.
Heat map monitoring of how outbound numbers appear on real phones, with spam-flagged numbers cleaned or removed and local-area caller IDs selected automatically.
Managers can listen to live or recorded calls, whisper coaching in real time, and run virtual salesfloor blitzes to motivate and train reps.

AI sales roleplay that scores every practice call against your playbook
Reps cold call, run discovery and negotiate with AI prospects that interrupt and push back, and scenarios can be generated from your own product materials and buyer personas.
On Professional and above, reps rehearse face-to-face conversations with AI avatars to practise on-camera delivery as well as verbal handling.
Every practice call is transcribed and scored, showing talk ratio, questions asked, next steps and the exact moment that lost the deal, with suggested alternatives.
Vonvo listens to real Microsoft Teams sales calls and suggests the next question or objection response in real time, visible only to the rep.
