Zac Gregg

Co-Founder, Managing Partner, ca. '01

True power is restraint.

Warren Buffett

After cutting his teeth in the Silicon Valley in the late 90’s and early 00’s, taking multiple companies public through his strategic approach to marketing and sales, Zac co-founded Vital with Julia Ahumada in order to do what he does best: design and implement digital marketing strategies that lead to measurable business growth. Over the course of his 20 years of leadership, Zac has grown Vital into one of the top digital marketing agencies in New England, employing 100+ of the most talented strategists, specialists, and account leaders in the business.

Today, Zac is well-known for his intuitive understanding of how to allocate digital marketing resources to drive the greatest possible return on investment (ROI). His unique combination of business acumen and marketing expertise — along with his obsession with measurement and quantification — has made him a trusted advisor to C-suite executives at some of the most successful companies in the world. Driven to help CMOs and marketing directors better understand how their marketing spend impacts customer acquisition, loyalty, and lifetime value, Zac is generous with his knowledge, pragmatic in his approach, and dialed into the latest developments in the field.

When he’s not reading, thinking, and talking about digital marketing, Zac enjoys spending time with his wife and two children on the beautiful seacoast of New Hampshire.
