Nothing of that kind in this list right now. "Find your organization" opens every one.
For organizations
When your board asks what changed, show the record.
Each organization keeps its own record of its programs, people and evidence, and works with its partners through one network. Every hour says how it was confirmed.
Proof
- U.S. nonprofits in our directory
- 1,388,549
- Counts the IRS-registered nonprofits our public directory can show, not organizations using TierSphere.
- IRS-registered tax-exempt organizations with an active IRS status, leaving out religious congregations and organizations that asked not to be listed. IRS data as of 21 May 2026; counted daily.
- of counted hours verified at the point of service
- 0%
- Counts approved hours only, and the share of them a person confirmed while the session was happening.
- Hours are counted only after the host approves them. None of the counted hours were captured at the point of service yet; the rest were entered afterwards or imported and are labeled Recorded.

Who TierSphere connects
Three kinds of organizations run their own work on the same network, and work together through it.
Educational institutions
Districts, schools and colleges keep their own programs, requirements and student records, and see the verified work their students do with the partners they connect.
- A district or school leader Your district runs forty programs with twenty partners. When the board asks what changed, you have anecdotes.
- A college or university leader Your campus runs service learning with dozens of community partners. The record of what service learners did lives in a dozen places.
- A student or family Everything your kid does outside the classroom, in one place you can actually trust.
Community organizations
Nonprofits, civic and service groups, membership organizations and associations keep their own members, volunteers, programs and evidence of impact, and share it with the partners they choose.
- A nonprofit or community organization You have been doing the work for years. TierSphere is where it finally counts.
- A volunteer or mentor Twenty-five years of showing up deserves a record someone believes.
- An association or membership network Your network runs dozens or hundreds of chapters. When you need one picture of what they did, you get a hundred versions.
- A government or civic leader Your agencies work with dozens of partners and programs. Nobody has one picture of the engagement, or the outcomes.
Funders and resource providers
Companies, foundations and grantmakers keep their own grants and giving, and see the verified activity of the organizations they support, as far as each relationship allows.
About TierSphere
Independent records, connected organizations
TierSphere is shared infrastructure for educational institutions, community organizations and funders. Each one manages its own stakeholders, work, resources, evidence and impact on it, and works with the others through one network without handing over its records.
Each organization keeps its own record
An educational institution, a nonprofit or association, a company or foundation manages its own stakeholders (the people it serves and works with), its programs and work, the resources it gives or receives, and the evidence and impact of that work on TierSphere. That record belongs to the organization, not to whoever it partners with.
One network connects them, on their terms
Organizations connect to do the work together: a college with the community partners it works with, a nonprofit with the funders who back it. Connecting shares only what that relationship allows: totals by default, and named people only for a specific purpose, like a placement or a program run together.
Evidence says how it was confirmed
Every hour is Reported, Recorded or Verified, and it says which. Verified means a person confirmed it at the time, or reviewed its evidence.
Consent governs young people
What is shared about a minor follows the family’s consent and the institution’s policy, and a partner sees only what its part of the work needs.
Impact says where it comes from
Impact on TierSphere is counted from what the connected organizations record on TierSphere. Work that never reaches the platform is not in it, and no figure pretends otherwise.
For the people who take part
Join the organizations you already show up for
Your record lives with the organization that confirmed it. Find it, ask to join or accept your invitation, and every hour you give says how it was confirmed.
- Find your organizationSearch by name or city. A claimed organization shows Ask to join.
- Ask to join, or use your invitationAn invitation link takes you straight to your organization, with nothing to search for.
- Sign up and startSee what is coming up, sign up for a session, and keep the record.
Were you invited? Invitations arrive as a link by email, and the link takes you straight to your organization. Families usually get a link or a code with their invitation. If yours has expired or gone missing, ask the person who invited you to send a new one.
