Straight talk

Where each one wins

What Grasshopper does well

  • Very easy setup for non-technical owners
  • Numbers and apps bundled in one bill
  • Simple mobile and desktop apps
  • Good fit for solo founders who just want a line

Where Grasshopper may still be the better fit

  • You want zero configuration and one bundled provider
  • You don't want to manage a SIP provider separately
  • You only need one number for one person
  • You prefer a polished consumer app over a PBX

Our honest take: for a one-person shop that wants the simplest possible setup, Grasshopper is a fine choice. If you have a team, want unlimited extensions, and want to own the call logs, our hosted PBX is the honest choice.

Frequently asked questions

Can I keep my existing business number?

Yes. You can port your existing number to a SIP provider we support, such as SignalWire or Twilio, and keep it while running our PBX behind it.

Does the virtual phone system charge per extension like Grasshopper?

No. Our PBX hosting is a flat monthly price, and you can add extensions, ring groups, and an auto-attendant without per-user fees.

Do I need special hardware?

No. You can use desktop and mobile SIP apps, or standard VoIP desk phones, all connecting to the hosted PBX.
