How it works

01

Finds your people

CloserOS scans for prospects matching your ideal customer profile. Company size, industry, role, signals. It builds the list so you don't have to.

02

Researches every prospect

Before writing a single word, it reads their LinkedIn, recent news, company updates. Every email references something real about them.

03

Writes and sends outreach

Personalized cold emails that sound human. Not templates with [FIRST_NAME]. Real messages based on real research. Sent at the right time.

04

Follows up and books

No reply? It follows up with new angles. Reply comes in? It handles the conversation and books a meeting on your calendar. You show up and close.

The old way vs. CloserOS

Without CloserOS

  • Hours building prospect lists manually
  • Generic templates that get ignored
  • Forgetting to follow up on warm leads
  • $60K+/year for one junior SDR
  • Pipeline dies when you get busy

With CloserOS

  • Prospects found and researched automatically
  • Every email personalized with real context
  • Follow-ups happen without thinking about it
  • Fraction of the cost of a human hire
  • Pipeline fills 24/7, even on weekends

Sales should run itself. Now it can.

CloserOS is the sales employee you've been trying to hire. Except it never quits, never forgets, and works every hour of every day.
