The Digital Agency Growth Podcast How Eric Baum Turned Plumbing Ads Into a Multi 7-Figure Agency
In this episode of the Digital Agency Growth Podcast, I’m joined by Eric Baum, founder and CEO of Blue Leads—one of the top HubSpot Solutions Partners globally.
Eric shares the full arc of his journey, from accidentally starting an agency after hacking Yellow Pages spend for his plumbing business, to scaling a team of 40+, to building one of the most successful HubSpot implementations agencies in the world.
We dig into what it actually takes to get out of the sales seat, build second-layer leadership, and scale without losing your mind.
If you're running an agency, this is a masterclass in letting go, thinking bigger, and staying relevant in a fast-changing market.
