Founded in DeForest.
Built for small business.
Mad Ad Slingers was founded by Chris Holmes in DeForest, Wisconsin. Chris spent nearly two years building the platform before it launched publicly on November 2, 2026.
Madison's big agencies charge big retainers and hand you an account manager. National software tools hand you a dashboard and wish you luck. We're neither. Mad Ad Slingers is a founder-led, AI-powered agency — close enough to know the Dane County market block by block, automated enough to run 10 ad platforms without the agency bloat.
Your campaigns, creative, spend, and results live in your own client portal, updated in real time. You always know what ran, what it cost, and what it made — no weekly PDF, no middleman, no jargon.
Slingy — the AI assistant who lives in your client portal.
