Overview

About Coldreach

Coldreach is an AI SDR agent that does real research on every lead - so your cold outreach actually gets responses. Before reaching out to any company, Coldreach researches their entire online presence to understand:

  • Do they have the pain point(s) you solve?
  • What's their status quo? (current tools, processes, team)
  • Are they in-market right now? (signals of urgency or change)

This research drives everything: which companies we reach out to now, and what we say to them. The AI SDR handles the rest - personalized email and LinkedIn outreach, automated follow-ups, and a private deliverability setup that almost never lands in spam.

The result: Outreach feels timely and relevant - because it is. 3.8% average reply rate (500k+ AI SDR emails sampled), 10x the industry average.
