Built for the scrutiny level auditors actually apply.
FairValueX is a valuation firm built on a proprietary methodology framework. We produce audit-defensible fair value for PE funds, CFOs, M&A counsel, audit committees, boards, and startup founders — with the documentation standard that addresses auditor scrutiny at every level, before the first question is asked.
Led by a senior valuation professional with Big 4 and boutique practice experience — disciplines where every judgment call must survive cross-examination by audit partners, opposing counsel, and regulatory examiners. Our team has executed engagements for VC-backed companies, PE funds, M&A counsel, and institutional clients — held to the documentation standard that auditors, LPs, and counterparty counsel actually apply. Every engagement is conducted in accordance with USPAP and applicable AICPA standards.
Documentation discipline is the standard. We hold it on every engagement.
Most valuation deliverables are built manually — every time. Same methods, same steps, different analysts, different outputs. When an auditor asks how a conclusion was reached, the answer is: dig through emails and try to reconstruct it.
That's not a defensibility problem. That's a documentation standards problem.
"The bottleneck in valuation isn't methodology. It's documentation discipline."
FairValueX was built to solve that problem — so that every engagement produces a deliverable auditors can reconstruct, boards can defend, and LPs can rely on.

Methodology & Documentation
Every engagement is documented through our proprietary TruthTrace™ framework — computation lineage, judgment documentation, and deterministic reproducibility built into every deliverable. The co-author reviews the model, approves methodology selection, and signs the opinion — expert judgment documented and substantiated at every step.
TruthTrace™ — Every material assumption. Documented and sourced.
Independence & Standards
FairValueX maintains independence from all clients. A conflict-of-interest check is performed before every engagement and independence is maintained throughout. Every engagement is conducted in accordance with USPAP and applicable AICPA standards — delivered under IRC §409A, ASC 718, ASC 805, and ASC 820 as applicable. For IRC §409A engagements, FairValueX qualifies as an independent appraiser under Treas. Reg. §1.409A-1(b)(5)(iv)(B)(2). Every report is co-authored and attested by a credentialed ASA or CPA/ABV as the named opinion signatory — human expert judgment on every engagement, not a signature formality. All reports undergo independent internal technical review prior to delivery. TruthTrace™ computation lineage provides verifiable reproducibility from the same source data and valuation-date inputs — every input, judgment, and output is traceable, timestamped, and deterministically reproducible. FairValueX carries professional liability (E&O) coverage — certificate available upon request.
The depth behind every engagement.
Every standard we work under.
What we believe.
Reproducibility Over Opinion
Same facts + same methodology = same result. Any qualified analyst should reach the same conclusion.
Speed Through Discipline
Rigorous process design eliminates procedural overhead — so analyst judgment gets 100% of the time, and your deliverable arrives exactly when scoped.
Credentialed Attestation
Every engagement is co-authored and attested by a credentialed ASA or CPA/ABV. Human expert judgment — documented, signed, defensible.
Audit-Ready by Default
Every deliverable is built for scrutiny — not polished for it afterward. The audit binder is the primary output, not an afterthought.
