Customer focused, data centric and driven by growth.

There are thousands of marketing agencies that generalize. That’s not us. We specialize in event marketing and use our deep expertise to fuel growth.

Event Marketing Experience and Customer Growth Built our Business.

Eventgrow was founded in 2018 by marketing professional Andy Reilly, whose 15 years in digital marketing, sales, and endurance event growth shaped the company’s approach. Andy spent four years at the ACTIVE Network supporting major endurance and experiential brands like Spartan Race and The Color Run. Those experiences helped define Eventgrow’s philosophy: data first, athlete focused, and built on genuine partnership.

Built on Real Results

Events started seeing measurable improvements in participation, revenue, and marketing performance. Some notable outcomes from our work include:

  • At the San Francisco Marathon, Eventgrow has delivered back-to-back record years in registration and revenue, driven by a unified marketing strategy across paid media, creative, campaigns, and operations. Over this period, return on ad spend has improved by 35 percent.
  • 20% registration growth over two years for the Buffalo Marathon

  • 20% percent registration growth over two years for the Buffalo Marathon

How We Show Up Today

What began as a small practice built around helping a handful of races solve real challenges has become a company focused on one mission: helping endurance events grow participation, increase revenue, and strengthen their impact on the communities they serve. Through thoughtful strategy, smart creative, and strong collaboration, Eventgrow helps events not just market better, but grow with intention and purpose.

We're on a mission to help our event partners build a path for growth.

We leverage our 15+ years of event marketing experience to accelerate sales and deliver on our promise. We’re data-driven, creative, and specialized in event marketing.
