What Our Clients Say

"Kirabas didn't just improve our ROAS — they completely changed how we think about advertising as a growth lever. The combination of their AI and our account strategist is genuinely different from anything we've tried."

JT

Jessica T.

CMO, Nordic Home Essentials

"We went from 6 disconnected agencies managing different channels to one team with a unified strategy. Attribution finally makes sense. We can actually see where our money goes."

ML

Marcus L.

VP Growth, Zenith Audio

"Post-iOS 14, Meta completely fell apart for us. Kirabas rebuilt our entire attribution and Conversions API setup in two weeks. ROAS recovered within 30 days of going live."
