Side-by-side comparison of AI visibility scores, market position, and capabilities
Volunteer engagement platform (founded 2017) acquired by Bonterra (Apax Partners, $2B deal 2021); 3,000+ orgs, 6M+ volunteers, used in 2024 Presidential campaign and April 2025 Hands Off protests competing with VolunteerHub for civic tech.
About
Mobilize is a volunteer engagement and event management platform for nonprofits, advocacy organizations, political campaigns, and labor unions — operating as a product within the Bonterra portfolio following its acquisition by EveryAction (NGP VAN parent) in November 2020 and EveryAction's subsequent $2 billion acquisition by Apax Partners in November 2021, which created Bonterra as the parent entity for civic engagement technology. Founded in May 2017 by Allen Kramer and Alfred Johnson — who brought direct experience from the Hillary Clinton 2016 presidential campaign and Barack Obama 2008 campaign and administration — Mobilize was initially funded by Higher Ground Labs, a progressive technology accelerator, before raising a $3.75 million Series A in January 2020 led by Higher Ground Labs with Lowercase Capital and Reid Hoffman. The platform serves 3,000+ mission-driven organizations and over 6 million volunteers, providing event creation (single-shift and recurring), virtual and in-person event management, automated volunteer communications, post-event feedback surveys, and integrations with ActBlue, EveryAction, NGP VAN, and other civic tech platforms. Organizations using Mobilize typically see volunteer signup rates double and no-show rates decrease 30%, while gaining access to 38% more volunteer shifts through the Mobilize network — with 45% of event signups coming directly from Mobilize's volunteer network rather than the organization's own outreach.
Apex Space raised $400M across Series C and D rounds in 2025, achieving a $1B+ valuation, as the first manufacturer to offer productized 100–500kg satellite buses at high production rates for commercial and government LEO constellation customers.
