# 15 Minute Intro with Logan Simmons

> A free 15 minute intro with Logan. No cost, no obligation, nothing to prepare. What we will do: Find out how many calls your business is actually missing. Your real number, not an industry average. Watch the system answer a call on your own line, live, while you are still on the phone with us. Ask us anything about AI, including what is overhyped and what we would not sell you. Optional, if you want to move fast: have your main business number handy. If you want more time, we stay on as long as you need. If it is not a fit for you, we will say so.
