Verifiable impact data, ready for recertification.
OM Guarantee gives B Corps blockchain-anchored proof of their social impact giving — independently verifiable, audit-ready, and exportable as supporting evidence for your B Impact Assessment.
● OM Guarantee is not affiliated with B Lab and does not issue or influence B Corp certification — we provide verifiable impact data you can submit as your own supporting evidence.
Recertification rewards measurable, credible impact
B Corps recertify every three years and must demonstrate real social and environmental impact. As scrutiny of impact claims grows, self-reported numbers carry less weight on their own.
Recertify every three years
Each cycle asks you to show measurable progress — not just intentions. Strong evidence makes that case easier to substantiate.
Self-reported claims face scrutiny
Assessors and the public increasingly expect impact claims to be backed by independent, checkable evidence rather than internal reporting alone.
Third-party-verifiable proof helps
OM Guarantee anchors every confirmed donation on-chain, so your giving impact is independently verifiable by anyone — including those reviewing your assessment.
Audit-ready evidence for your impact giving
Confirmed and anchored on-chain
Every donation is confirmed via Every.org and anchored on Polygon — a tamper-evident record of giving that doesn't rely on your word alone.
Public verification pages
Each verified contribution gets a public page anyone can check, giving you audit-ready evidence to reference in your B Impact Assessment.
Exportable, shareable data
Impact data is exportable and shareable, so you can include it as supporting evidence alongside the rest of your recertification materials.
Works alongside your commerce
One script tag works on any platform — no replatforming, no migration. Add verifiable giving to how you already sell.
OM Guarantee is itself a Certified B Corporation
OM Guarantee is a Certified B Corporation with an Overall B Impact Score of 107.5 — well above the 80 needed to qualify. We hold ourselves to the same standard our merchants are working to meet, because credible impact starts with credible practice.
