Competitive landscape

Edge: Integrated campaign stack in one product — organizers don't need separate tools for website, email, and CRM.

Campaign tech is politically segmented — NGP VAN dominates Democratic data. NationBuilder serves bipartisan campaigns and international causes with integrated website+CRM. Older platform but established user base.

  • NGP VAN (Bonterra) direct

    Democratic campaign data and organizing.

  • ActionKit direct

    Advocacy and campaign CRM.

  • HubSpot adjacent

    General marketing CRM; less campaign-specific.

  • Mailchimp adjacent

    Email only; no campaign CRM.

Notable stories

  • Ben Horowitz joined NationBuilder's board at Series A — a16z's early civic-tech bet before current American Dynamism framing.
