As founder of Qool Media, Paul developed a marketing platform that powered large scale publisher experiences and $10m's of advertising.

Across these roles, Paul has orchestrated significant capital raises, M&A transactions, and the scaling of revenue from early-stage millions to nine-figure run-rates.
