Founding beta questions
What does the founding beta include?
The full phone system, free for a year: a local or toll-free business number, call forwarding, greetings and extensions, shared texts, voicemails emailed with a transcript and AI summary, and callbacks from the business number.
Why is it free?
Founding members use Numberline every day and tell us what works. The free year is our thank-you.
What does it cost?
Nothing for a year, and no card to start. We email you before your free year ends, and nothing switches on without your approval.
Who gets in?
Startups, founders, entrepreneurs, and small businesses that will use the phone system day to day. We review every application personally and reply by email.
Can I bring the number I already have?
Yes, if the number is eligible. Tell us in the application; the porting timeline is set by your current carrier. See the porting guide.
Do I need a team to join?
No. Many founders start solo: the business number forwards to your own mobile, and callbacks show the business number. Add people whenever you like, with no per-user pricing.
How soon will I hear back?
Usually within a few days. After we review your application, we email you the next steps to set up your number and get started.
