David Cullinan is a strategic storyteller and growth advisor who has spent the past 15+ years helping brands, founders, and emerging tech companies shape narratives that drive action. With a background spanning journalism, venture-backed startups, fintech, and climate tech, David built WhiteOak Media to serve one purpose: to give high-performing founders a sharper, more credible voice — and place that voice where it matters.

He’s led content and growth strategy for companies across the UK, US, and UAE, with a client portfolio that includes SaaS firms, blockchain pioneers, and VC-funded platforms. Prior to launching WhiteOak, David served as CEO of a climate-tech platform and advised multiple early-stage ventures on positioning, capital readiness, and go-to-market clarity.

Now, through WhiteOak, he leads a team that crafts founder-led content and delivers guaranteed placement in publications like Forbes, Nasdaq, Entrepreneur, and VentureBeat — turning visibility into reputation, and reputation into results.
