Nothing to install — it just opened in a browser tab

Challenge

After every demo, the sales team huddled to argue about whether the prospect "seemed into it." The call had been on Zoom — every word, every facial expression, on tape. Nobody was looking at the tape.

Constraints

  • check_circleHad to run right in the browser — nothing to install
  • check_circleSensitive sales calls could never leave the company's hands
  • check_circleHad to keep up live, on a normal laptop

Approach

A tool that runs in a browser tab and reads both the voice and the face on a sales call — scoring engagement live, so the team follows up on the call, not a hunch.

Architecture

  1. 01Reads facial expression on the call
  2. 02Reads tone and energy in the voice
  3. 03Picks up the signals that show whether someone's actually interested

Implementation

  1. 01Built the voice analysis from scratch
  2. 02Combined the voice and face read live, during the call
  3. 03Runs in a browser tab — nothing to install, no IT involved

Results

  • check_circleScored how engaged the prospect was, live on the call
  • check_circleGave the team a real read instead of "I think it went well"
  • check_circleNothing to install — it just opened in a browser tab

Business impact

  • check_circleThe team knew when to follow up — based on the call, not a hunch
  • check_circleLess arguing about whether the prospect "seemed into it"
  • check_circleLet them see which pitch actually landed
