About

Who Niall is, in her own words.

Niall O'Gorman is the CEO and Founder of MarketSizer. He founded the company in Dublin in 2023 to help GTM teams cut through the noise of intent data and act on real subscription-level buying signals.

His background spans commercial and technical roles across Mondelez, ChannelSight, and MarketSizer, giving him an operator-led perspective on how B2B growth works when signals meet timing. He writes about market sizing, purchase intent, and the machinery of building an evidence-led GTM motion.
