Problem Research
Cold calling: a dying art or doomed?
Sales is still one of the most labor-intensive functions in any company, and the data paints a brutal picture of how reps actually spend their time.

Problem Research
Sales representatives waste the majority of their workday on repetitive, low-value outbound calls, leaving voicemails, repeating the same pitch, confirming available hours, and dialing through contact lists, while only 33% of their time goes toward actual selling.
How Might We?
HMW automate the 67% of a rep's day lost to repetitive, non-selling tasks without feeling robotic, hand control back to the human at exactly the right moment, not too early, not too late, while scaling their outreach 10× without degrading conversation quality, and turning every completed call into a learning loop that makes future campaigns smarter?
User Persona
Features
Campaign Creation
A campaign is the core unit of nAgent. It's a self-contained call automation that packages everything the AI needs to make calls on the rep's behalf.
Live Call Controls
Once campaigns are running, the rep has three levels of interaction with any live call:
Take Over, Whisper, Monitor
Call Templates
For high-volume outreach where dozens or hundreds of calls follow the same structure, templates eliminate repetitive campaign setup.
Playback & AI Summary
Every completed call generates a post-call report: Full Transcript, Audio Playback, AI Call Summary
