What you get

Tools built for small nonprofit teams.

  • Verified badge

    Your organization is automatically cross-checked against the IRS Business Master File (501(c)(3) status). Florida Check-A-Charity and Sunbiz lookups are next on the verification roadmap. Sponsors see the verification status on your card.

  • Sponsor-side discovery

    Browse opted-in sponsors filtered by cause, budget, and active-looking status. Pitch them directly.

  • Smart match surfacing

    Sponsors with cause interests matching your mission see your events surfaced in their feed. No cold outreach required.

  • No platform fees

    Free to list, claim, and receive interest. Summit Labs maintains the platform as a civic contribution.

What this is not

Honest about scope.

  • — We do not broker deals. Once a sponsor expresses interest, the relationship lives between you and them.
  • — We do not process payments. Sponsorship transactions run through your existing processes.
  • — We do not guarantee matches. Match quality depends on sponsor alignment and your event quality.
  • — We do not sell your data. Sponsor contact info goes to you, not to third parties.
