CallHub vs Mobilize Comparison: Everything You Need to Know Before Choosing

Mobilize is an event management and volunteer recruitment platform, now part of Bonterra, that connects mission-driven organisations with supporters who want to take action. Political campaigns, advocacy groups, non-profits and community organisations rely on volunteers and event attendance to achieve their goals, yet recruiting, scheduling and retaining supporters is often managed through spreadsheets, generic event tools and email chains. This makes it difficult to measure participation, follow up effectively and grow engagement over time. Mobilize addresses these issues by providing a platform built specifically for organising, where groups can publish events and volunteer opportunities, supporters can sign up easily and organisers can track involvement. Its approach emphasises a smooth sign-up experience, automated reminders and data that helps organisations move supporters up a ladder of engagement, from attending a single event to taking on leadership roles. The platform is designed so that organisers with limited technical resources can launch recruitment drives quickly and scale them during busy campaign periods. Key features include event creation with support for in-person and virtual activities, shift-based volunteer scheduling, customisable sign-up forms, and automated confirmation and reminder messages by email and text message. A public event feed and embeddable widgets help supporters find opportunities, while distributed organising features allow volunteers to host their own events under the organisation's umbrella. Attendance tracking, follow-up tools and reporting provide visibility into participation, retention and the effectiveness of recruitment efforts. Integrations with CRMs and voter databases such as EveryAction, NGP VAN, ActionNetwork and Salesforce ensure supporter data flows into the organisation's wider systems. The platform is cloud-based, with mobile-friendly interfaces for supporters and organisers. Target customers include progressive political campaigns, party committees, advocacy organisations, unions, non-profits and community groups in the United States. Pricing starts from around USD 200 with a free trial; there is no permanently free version.
