03

A direct line to the team.

Your feedback goes to the people building Numberline, and it shapes what ships. Tell us what your phone system should do.

What we ask

Help us test & shape it.

The beta is for businesses that will use Numberline for real. That is how we find what matters.

  • Use it as your business line.Put the number on your website and your cards, and run your calls and texts through it.
  • Tell us what works and what does not.A short check-in every few weeks, and a reply when something gets in your way.
  • Expect some rough edges.It is a beta. Features will change, sometimes because you asked for it.

Founding beta questions

What does the founding beta include?
The full phone system, free while the beta runs: a local or toll-free business number, call forwarding, greetings and extensions, shared texts, voicemail transcripts, and callbacks from the business number.
What does it cost?
Nothing during the beta. No card to start. When the beta ends, founding members get founding-member pricing before public pricing takes effect, and nothing switches on without you approving it.
What do you expect from beta members?
Use Numberline as your real business line, tell us what works and what does not, and be patient with rough edges. A short check-in every few weeks is all we ask.
Who gets in?
Startups, founders, entrepreneurs, and small businesses that will actually 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. Numberline is designed to support porting your current business number. Tell us in the application and we will share the porting steps when your setup opens.
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 instead of your cell. Add people whenever they exist, with no per-user pricing.
How soon will I hear back?
Usually within a few days. If you are accepted, we email you with the next steps to set up your number.
