BizHack's Founder

Dan Grech

Lead Instructor & Founder
dgrech@bizhack.com


After nearly two decades as a journalist and storyteller, I have reinvented myself as a digital marketer and educator. I’ve headed digital marketing at billion-dollar companies and software startups, and I’ve consulted for hundreds of businesses. I believe in the power of digital marketing to transform lives and businesses. And I want to share what I learned with you.

Some fun trivia about me: My first startup was founded by Eric Reis, author of The Lean Startup. I was interviewed for Tim Ferriss’s book The Four Hour Workweek. I was part of a Pulitzer Prize team while I was an intern at The Miami Herald. And I’ve performed in an improv troupe for more than a decade.
