Charlie Chang’s apps

Client Acquisition OS

Prospecting, outreach, follow-ups, and sales tracking.

Prospecting, outreach, follow-up and pipeline for a service business, without a full CRM's setup cost. It is built around the fact that most deals are lost by not following up rather than by being rejected.

What a v1 does5 features
  • Prospect lists built and enriched in the app
  • Multi-step sequences with automatic follow-ups
  • Every reply in one inbox, with the deal attached
  • A pipeline with stage ageing, so stalls are visible
  • Consent and unsubscribe handling for email and SMS

Why this audience

These viewers lose deals to silence rather than to competitors, because follow-up is manual and they are busy delivering. They already know outreach is a numbers game. Sequences and a pipeline turn a belief they hold into a process.

Fifty thousand paying users is the ceiling every one of these pages is drawn against, not a forecast. It opens at a thousand, the bottom of the range, so the first figures you see are the modest ones. What the cap buys is comparability: the same range on every app, and the percentage of the audience it takes as the number that moves.

Is this the one for your audience?

We fund it, build it, and run it. You bring the audience and take a share of the revenue. Nothing to pay and nothing to build.
