01Capture
At the source.
Evidence is captured where the work happens — a hardened field sensor inside a verified perimeter, not a checkbox typed into a desktop app the following Friday.
- Field-grade sensor
- Geofenced perimeter
- Hardware attestation
TAEVUM
Social impact is about to get audited.
We are the cryptographic provenance layer for the S in ESG. Field-captured, hardware-signed, audit-grade evidence — built for the sustainability office Deloitte is about to audit.

CSR software records intent.
Taevum records proof.
Fortune 500 companies spend $0B a year on corporate social impact. For two decades it has run on the honor system — volunteers type hours into a portal, managers bulk approve, funds sit in a proxy foundation for ninety days, a consultant writes the PDF, the auditor signs and moves on.
That model is now legally obsolete. California SB 253, SB 261, and the EU CSRD require corporate sustainability data to pass the same audits as the financial statements they sit beside. Self-reported web forms instantly fail.
The Fortune 500 is about to need a verification layer that does not exist yet. We are building it.
Three layers.
One unbroken chain of evidence.
The structural properties of the system are public. The composition that makes them work in production is not. What follows is the shape, not the secret.
02Verify
Cryptographic.
Every capture is sealed at the device with provenance metadata that survives adversarial review. The chain binds the recorded payload to a specific instrument, a specific moment, and a specific place. Tamper-evident by construction.
- Tamper-evident media
- Device-bound signature
- Real-time seal
03Attest
Audit-ready.
Every verified action is issued as an open, vendor-neutral credential, mapped to the disclosure schemas the buyer's auditor already uses. The credential is the report. The auditor queries it directly.
- Open credential schema
- SB 253 · SB 261 · CSRD
- ESRS · ISO · IFC PS
Not a PDF.
Not a screenshot.
A signed, queryable credential.
Every action that crosses the platform — a volunteer hour in a Sydney warehouse, a solar streetlight in Goma, a school built beside a Nevada lithium mine — emerges as a single open-standard artifact. Capture timestamp. Geofence anchor. Device attestation. C2PA media manifest. Issuer signature. Schema mapping.
One credential, mapped to every disclosure regime the buyer answers to. An auditor verifies it in seconds and traces it to the device that captured it. The credential is the report.
Capture-to-credential latency, under sixty seconds.
Three regulations.
Two continents.
All forcing social verification.
The carbon disclosures get the headlines. These are the regulations that compel corporate disclosure on the S. The sustainability office walking into its 2026 audit without a verification layer for the social block will be the one explaining why.
Jan 2026
EU CSRD · ESRS S1–S4
Wave-2 issuers begin filing the full social block: S1 own workforce, S2 value-chain workers, S3 affected communities, S4 end-users. Machine-readable, audit-required, traceable to the field. Wave 3 (listed SMEs) follows in 2027.
Jul 2026
EU CSDDD
Member-state transposition deadline for the Corporate Sustainability Due Diligence Directive. Mandatory human-rights and value-chain due diligence with civil liability for harm. Phase-in begins 2027 for companies above €1.5B in turnover.
FY 2025
India Companies Act § 135
The 2% CSR mandate. Indian corporates spent ₹26,000 Cr (~$3B) on social impact in FY24, every rupee subject to MCA impact-reporting requirements. The largest single regulatory wedge for verified social proof.
Speaks the language
your auditor already uses.
Every capture maps to the disclosure schemas already on the buyer's desk. We do not need to be the standard. We need to be the proof underneath it.

Carbon platforms see
half the picture.
The sustainability stack has a hardware-verified evidence layer for emissions. It does not have one for human action. That is the wedge.
Carbon platforms.
Watershed and Persefoni measure CO₂. The S in ESG sits outside the ledger — a blind spot in every audit.
Engagement portals.
Benevity and YourCause record self-reported timesheets. Auditors classify the underlying data as inadmissible.
Voluntary disclosure tooling.
Workiva and Sphera convert PDFs into reports. The proof layer underneath the disclosure is missing.
TAEVUM.
The cryptographic provenance layer for social impact. Field capture, signed at the device. Audit-grade by construction.
Don't trust.
Verify.
We are onboarding a small cohort of sustainability offices and NGO networks before our public launch. If your audit cycle reaches your desk before ours does, we should talk.
