## About

WhoSignup — Never miss a high-value signup again

WhoSignup helps SaaS founders and marketers get instant alerts when valuable companies sign up for their product.

Instead of manually checking dashboards or filtering out low-quality signups, WhoSignup enriches each signup with company data (size, industry, domain authority) and notifies you only when it matches your ideal customer profile.

How it works:

- Send signup data to WhoSignup via a simple REST API

- The tool enriches it with company information

- Define smart rules (e.g. “notify me if company has 50+ employees” or “domain authority > 60”)

- Get instant email notifications when those signups happen

Why use it:

- Stop missing enterprise or high-value leads

- React fast and send personal follow-ups

- Set up in minutes with a simple API
