How do startups use OpenPhone?
OpenPhone is built to be incredibly easy to set up and scale with you as you grow.

Main company number

  • Keep your personal number private: Prevent endless cold calls and spam to your cell.

  • Share your number with co-founders: Split responsibility fielding calls and texts.

  • Make your startup look more established: Use phone menus, auto-replies, and other tools to stay on top of conversations.

Just a piece of advice. I used my personal cell number as the company number and I still regret it a decade later (I get so many stupid calls). Don't do what I did. I wish I had this service like 10 years ago!
