About
CallFast is an AI phone calling tool. It calls your leads in seconds - after they fill out an enquiry form on your website - to book an appointment with you. This means the lead gets a quick call and you come in to booked appointments instead of cold leads. Integrates with any form tool to receive leads. Then send the appointment and lead data to your calendar and CRM so your other tools stay in sync.
