How Colder Works

Three things happen
when you turn it on

01

It finds who to talk to

Colder researches your market and builds a list of prospects that actually match your business. Not a generic database dump. Real leads with context.

02

It writes like a human

Every email is crafted from scratch based on the prospect's business, challenges, and recent activity. No templates, no merge tags, no spam.

03

It follows up and books

Automatic follow-ups with perfect timing. When a prospect shows interest, Colder handles the scheduling back-and-forth and puts meetings on your calendar.

Why this is different

Hiring an SDR vs. turning on Colder

Traditional SDR

  • $60,000+/year salary plus benefits
  • 3-6 months to ramp up
  • Works 8 hours, 5 days
  • Inconsistent follow-up
  • Quits after 14 months (average)

Colder

  • Fraction of one month's SDR salary
  • Active from day one
  • Works 24 hours, 7 days
  • Never misses a follow-up
  • Gets smarter every week

Small businesses deserve
a sales team that never stops

Enterprise companies spend millions on sales infrastructure. Colder puts the same firepower in your hands for the cost of a nice dinner.
