You Built Your Business to Serve Customers — Not to Be Chained to Your Phone

Missed Call Phone Screen

You're missing calls while you work

Whether you're with a customer, on a job site, or finally off the clock, your phone keeps ringing — and every missed call is a lead that calls your competitor next. Voicemail doesn't convert.

Calendar scheduling

Screening and scheduling eats your day

Answering the same questions, qualifying the same types of leads, and going back and forth on appointment times — it's repetitive, exhausting work that keeps you from growing your business.

Financial stress

Hiring front desk staff is expensive

A full-time receptionist costs $35k–$55k per year — and they still can't answer calls at 11 PM on a Sunday. Part-time staff come with training headaches and payroll complexity.

KairosFS Does the Work of a Full-Time Receptionist — for a Fraction of the Cost

Small Business Owners Who Found Their Secret Weapon

"I was skeptical at first — I didn't think an AI could handle the nuanced questions my HVAC customers ask. But it does. KairosFS qualifies leads better than my last two receptionists combined, and it works at midnight when they definitely don't."
Derek M.
Owner, Summit HVAC Services
"As a real estate agent, speed-to-lead is everything. KairosFS answers my calls, pre-qualifies buyers and sellers, and texts me the hot ones instantly. I've closed two deals that came in after 9 PM that I would have missed before."
Patricia N.
Realtor, NorthView Properties
"I run a law practice with two staff. We simply could not afford a full-time receptionist. KairosFS is the equivalent of a $4/hour, 24/7 receptionist who never calls in sick. It paid for itself in the first week."
Robert K.
Managing Partner, Keller & Associates Law
