Zelos Team Management vs. haku

Zelos is a self-signup app that lets volunteers, crew and contractors claim work instead of being assigned shifts. Organizations use Zelos to publish available work, let team members choose what they want to do, and coordinate the people who sign up. It combines task and shift signups with team communication, giving organizations a simple alternative to spreadsheets, group chats, and traditional scheduling tools. Zelos is designed for nonprofits, community organizations, events, and other teams that coordinate volunteers and on-demand crews.

haku is an all-in-one platform for events, fundraising, marketing, and engagement, powering endurance events and nonprofit organizations. Established in 2013, we began by transforming endurance events with flexible technology that simplified management and drove growth. Since then, we’ve brought that same innovation to nonprofits — helping organizations power events, fundraising, marketing, and engagement so they can focus on impact, not fixing broken systems.
