Ignite Startups: The Rise of Creator-Led Marketing in B2B with David Walsh | Ep261

What happens when the same founder who once scaled a $30M HR tech company decides he picked the wrong problem—and starts over with a completely different bet on how companies grow?

David Walsh is a three-time founder, former professional rugby player from Dublin, and now the CEO of Limelight, a fast-growing platform building the operating system for B2B creator-led marketing. After scaling and exiting his previous company, he made a deliberate shift: away from HR tech and toward marketing leaders, where he saw a deeper, more urgent pain around distribution and rising customer acquisition costs.

Limelight sits at the center of that shift. The company helps brands like HubSpot, ZoomInfo, and Webflow turn creator content into measurable pipeline, not just awareness. Instead of relying on agencies or traditional paid channels, it gives companies a structured way to work with B2B creators and track real revenue impact.
