Who we serve

Built for tradies, agents & attorneys

We specialize in verticals where speed-to-answer determines whether you get the job or your competitor does.

HVAC, Plumbing & Contractors

Emergency calls handled 24/7. Urgent jobs routed to you immediately. Non-urgent leads booked into your calendar. You focus on the work.

Before: Voicemail during peak hours → competitor gets the job. After: Every call answered, every opportunity captured.

Real Estate Agencies

24/7 lead capture for property inquiries. Showing scheduling, buyer qualification, and agent follow-up — automated. Every inquiry answered, even at midnight.

During a showing, you can't answer your phone. AgentStack captures every lead and books the follow-up.

Law Firms & Legal Practices

Preliminary intake handled automatically. Case type captured, urgency assessed, consultation booked. You only take calls that matter.

60-70% of law firm calls are routine inquiries. AI handles them all, so your time goes to actual client work.

The businesses winning in 2026 aren't the ones with the most staff. They're the ones with the best systems.

Every missed call is a competitor's win. Every manual data entry is time stolen from growing your business. AgentStack builds the automation layer that turns your operations into a competitive advantage.
