Shared Due Diligence. Lower Friction. More Capital into Communities.

Diligence League is a membership-based investment platform that reduces the cost, time, and duplication of due diligence for asset owners and investment advisors investing in communities. By sharing institutional-quality diligence on emerging managers, intermediaries, and Community Development Financial Institutions, Diligence League helps capital move more efficiently while maintaining rigor and fiduciary integrity.

The Challenge: Across impact and community investing, the same barriers appear again and again.

  • Due diligence is expensive
  • Processes are duplicative
  • Managers are repeatedly burdened
  • Advisors navigate non-reliance constraints alone
As a result, capital that wants to move often slows or stalls before it reaches communities.

The Diligence League Solution: Diligence League creates shared infrastructure for diligence.

Members pool resources to commission high-quality, standardized due diligence that can be used up to the point of advice. This approach reduces friction while respecting legal, fiduciary, and compliance requirements. Inspired by the Common Grant Application, Diligence League applies a proven shared-services model to investing.

How It Works
  • Asset owners collaborate to fund and co-own diligence
  • Emerging managers, intermediaries, and CDFIs undergo standardized review
  • Investment advisors gain efficient access to vetted materials
  • Diligence costs are shared rather than duplicated
  • Non-reliance requirements are thoughtfully addressed
  • Capital moves faster and with greater confidence
Who It’s For

Asset Owners: Foundations, trusts, donor-advised funds, family offices, and institutional allocators seeking efficient diligence and broader access.

Why It Matters
