The journey to On-Call CMO began with our founder Thomas Gaydos in the trenches of high-growth technology companies. As a founding marketer at Evolve IP, where he scaled from zero to $100 million in just six years, and later as CMO at McFadyen Digital, where he achieved consecutive Inc. 5000 honors, Tom witnessed firsthand how strategic marketing leadership can transform ambitious companies into market leaders.

​

He also saw a gap in the market: growing companies that needed sophisticated marketing leadership but weren't ready for a full-time marketing executive role. This insight led to the creation of On-Call CMO, providing fractional executive marketing leadership specifically designed for technology startups and emerging businesses.

​
