Case Study: GirlTrek achieves nationwide mobilization and membership growth with NationBuilder

Mobilizing a nationwide health movement

GirlTrek, a national health movement and the largest nonprofit serving Black women and girls, set an ambitious goal to recruit 1 million walkers by 2018 and needed an online platform to inspire signups, empower local leaders, and boost community support. They partnered with NationBuilder (via agency Herman‑Scheer) to build their movement site on the NationBuilder platform.

NationBuilder delivered a custom, feature-rich site — with MapMyWalk integration, a dynamic leaderboard, redesigned event calendar, action‑inducing videos, an Organizer’s Toolkit, and a Shopify storefront — to simplify joining, organizing, tracking, and donating. The NationBuilder-powered implementation drove measurable growth and engagement: as of 2017 GirlTrek had inspired 84,166 pledges across 27 cities and grew by over 50,000 Trekkers in one year, strengthening recruitment, fundraising, and member activity tracking.
