Justin Day

Founder of SwarmSystem

Justin Day has spent ten years getting local businesses found, and his work has generated over $100 million for clients.

He started at his mother's agency in downtown Dallas. From there he grew a one-person video shop into a 30‑person agency.

Then he cut it down to one thing: SEO and AI visibility for home service businesses in HVAC, plumbing, electrical and roofing. That one thing is SwarmSystem.

He reports results as revenue by channel, not traffic or rankings.

His TEDx talk, Will AI Take Over the World?, has nearly 1.3 million views.
