Martin O'Leary Startup Marketing

Uncharted is marketing strategy for startups at the intersection of technology and reality.

I'm Martin.

I've scaled fintech from zero to 100k customers. Twice.

Built Ireland's first digital bank. Led marketing through a Fortune 500 acquisition. Generated 27x ROI on marketing spend. Currently on the management team of a major MENA fintech.

Now I share what actually works when Silicon Valley playbooks meet real markets.

Every week you get

  • Mental models for startup growth.

  • Marketing tactics that actually work.

  • Insights from the marketing technology intersection.

  • Patterns from working with founders.

Sometimes it's strategy. Sometimes it's a founder reality check. Always something you can apply.

No theory. No fairytales. Just what works when the map is wrong.

Join 5k+ founders and marketers who get Uncharted every week.
