Simple phone system for freelancers and agencies working with international clients
Get a dedicated USA number and start calling your US and Canada leads in under 30 seconds — no cranky CRM plumbing, no shared number pools, no spam labels.
The problem
Sound familiar?
You have email, Slack, WhatsApp — but no USA number
You can message leads all day, but you can't pick up the phone and call them directly. A real USA number changes your conversion rate.
No one-stop solution for voice calling
Most freelancers waste hours plumbing together voice APIs with cranky, expensive CRMs just to make a simple outbound call. It shouldn't be this hard.
Shared number pools = 'Spam Likely'
Cheap calling tools put you on shared number pools with hundreds of other callers. Your prospect sees ‘Spam Likely’ before they even pick up.
How it works
Sign up to first call in under 30 seconds
Sign up
Create your account with your email. Takes under a minute. Five free calling minutes are included so you can test right away.
Get your dedicated USA number
A real US +1 number assigned exclusively to you. Your prospects see your dedicated number — not a shared pool marked as spam.
Import leads, call, track
Upload your leads from CSV, start calling immediately, and log call notes in the built-in CRM to track your pipeline.
