Rosie is an AI Phone Answering Service for Small and Medium Businesses.

With Rosie, businesses can make sure they never miss another call from a potential customer, as well as take great care of existing customers.

The AI will answer the phone 24/7/365, provide callers with accurate information, take effective messages for the business, and even set appointments directly on your calendar.

If you're tired of seeing missed calls, prospective customers hanging up on voicemail, and not being able to answer the phone while on the job or when the office is closed, Rosie is the answer.

It's simple to set up in minutes, forward calls to your new Rosie number when you can't answer the phone, and then manage calls in your Rosie admin.

Key Features include:

  • Always available: Rosie is always on. 24/7/365. Perfect for when you’re busy or after hours when no one is available.
  • 10x better than voicemail: Make the most of every opportunity. Never send a new customer to voicemail.
  • Effective message taking: Define the key information you need from callers, and Rosie will collect it all and send your way to qualify the call.
  • Appointment setting: Have Rosie book appointments directly on your calendar or CRM, based on your current availability.

Rosie is perfect for home service businesses, local businesses, or any businesses that have new leads calling them on the phone.
