After every sales demo, someone should ask the prospect how it went. Nobody ever does. demo-feedback asks automatically — and turns the answer into a hot / warm / cold signal the team can act on.

OutcomeA hands-off loop from calendar to scored signal — zero manual sends.
Problem

Post-demo feedback dies in the follow-up.

A demo ends, everyone moves on, and the one moment the prospect actually has an opinion slips away. Asking by hand doesn’t scale — so it never happens consistently.

How it works

From calendar to commercial signal, automatically.

  1. 01
    Calendar watch

    An Apps Script polls the sales calendar every minute.

  2. 02
    Demo detected

    A just-finished call with an external guest triggers the flow.

  3. 03
    Branded ask

    The prospect gets a personal form link, sent from the rep’s own Gmail.

  4. 04
    Scored

    Structured answers become a 0–100 score and a hot / warm / cold signal.

  5. 05
    Sales acts

    Clean, queryable results land in Supabase, ready for follow-up.

The branded form the prospect fills — sent automatically from the rep’s own inbox right after the demo.
What I builtDeep dive

A pipeline built to never double-send.

  • Trigger

    Apps Script watches Google Calendar and calls a secured Vercel endpoint with a shared secret.

  • Backend + form

    Next.js API routes mint a unique token per invite and serve a branded form.

  • Scoring

    Structured answers convert to a 0–100 score and a clear commercial signal.

  • Deduplication

    Unique calendar-event IDs block double sends in both the script and the database.

Why it matters

Design and engineering in one loop.

I owned the flow, the form, and the backend end to end — a small, complete system that shows what “designs and ships” means in practice.
