Andersen is the best pick for finance teams managing multiple equity events because its assumption documentation is built into board-ready report packages, making internal review and governance packet assembly smoother, while Carta Valuations fits equity operations already running in Carta thanks to cap table integration that reduces valuation intake rework during refresh cycles.
Editor’s top 3 picks
Three quick recommendations before you dive into the full comparison below — each one leads on a different dimension.
Andersen
Assumption documentation inside each engagement package supports internal review and board packet assembly.
Best for: Fits when finance teams need consistent independent 409a delivery for multiple equity events.
Withum
Editor pickMaterial event update support that maintains valuation defensibility after changes to capital structure or business facts.
Best for: Fits when startups need method-driven 409A reporting and disciplined refresh handling for equity compensation decisions.
Carta Valuations
Editor pickValuation intake and report production reuse the same equity and capitalization data used for day-to-day cap table management.
Best for: Fits when equity operations run in Carta and need repeatable 409A refresh workflows.
Comparison Table
Andersen
enterprise_vendorAndersen performs independent 409A valuations and advises on equity compensation valuation matters.
Assumption documentation inside each engagement package supports internal review and board packet assembly.
Andersen’s 409a delivery centers on a valuation team workflow that turns company inputs into a defensible fair market value with explicit assumptions and key drivers captured for review. The engagement structure is geared toward companies that need repeatable valuation refresh cycles and clear audit trails for internal stakeholders. The output format is designed to support board approval and document retention for equity compensation governance.
A tradeoff is that Andersen’s process favors structured information and timely coordination, which can slow turnaround when inputs like capitalization details or preferred stock rights are incomplete. Andersen fits best when finance and equity administration teams need a consistent provider to run multiple valuation events across option pool changes and material event updates.
- +Board-ready report packages with documented assumptions and governance support
- +Methodology coverage built for equity compensation events and effective dates
- +Independent valuation workflow designed for consistent refresh cycles
- +Clear handling of illiquidity discount inputs and valuation drivers
- –Requires timely, complete capitalization and preferred terms data
- –Less flexible for highly custom valuation methodologies outside standard approaches

Best for: Fits when finance teams need consistent independent 409a delivery for multiple equity events.
Withum
enterprise_vendorWithum provides 409A valuations and equity compensation advisory for private businesses.
Material event update support that maintains valuation defensibility after changes to capital structure or business facts.
Withum delivers IRS-compliant 409A valuation reports that translate documented valuation methods into defensible common stock assumptions for option pricing. The workflow supports board approval timing by aligning valuation inputs with equity plan terms tied to the valuation effective date. It also supports refresh needs by updating pricing when material facts change after the initial valuation.
A key tradeoff is that the engagement depends on timely, complete company inputs like cap table details and operating data to keep the valuation memo defensible. One common fit is a private company that needs governance-ready valuation documentation for equity compensation decisions tied to a specific effective date.
- +Strong documentation for methods and assumptions used in the 409A report
- +Material event update workflow supports pricing continuity after changes
- +Equity plan term review ties valuation output to board approval needs
- +Consistent handling of capital structure inputs used for fully diluted analysis
- –Data gathering can be heavy when capital history is incomplete
- –Tends to require tight coordination with finance on valuation inputs
- –Limited public detail on automation or API driven integration surfaces
- –Report turnaround depends on how quickly requested documents are provided

Carta Valuations
specialistCarta provides 409A valuation reports for private companies issuing employee equity.
Valuation intake and report production reuse the same equity and capitalization data used for day-to-day cap table management.
Carta Valuations is designed for teams that already use Carta for cap table operations, because valuation data can be derived from the same equity records used for fully diluted capitalization tracking. The workflow focuses on producing the 409A report package needed for governance cycles, including board packet readiness around the valuation effective date. Integration depth reduces dependency on spreadsheets for common inputs such as capitalization and preferred stock rights context.
A key tradeoff is that deeper automation depends on having accurate, maintained equity records inside Carta, so gaps in that data will carry into the valuation intake. Carta Valuations fits best when a company needs repeatable valuation refreshes, such as after equity grants or restructuring events, where consistency matters more than one-off manual modeling.
- +Cap table integration reduces valuation intake rework
- +Governance-ready workflows support board approval packaging
- +Repeatable refresh process improves consistency across updates
- +Clear audit trail support for input and report delivery handoffs
- –Accuracy depends on maintained equity records in Carta
- –Limited fit for teams that do all cap table work outside Carta
- –Modeling customization can feel constrained versus bespoke providers
- –API-heavy automation requires internal process alignment

How to Choose the Right 409a Valuation
The difference between options is how they document and manage 409a valuation decisions over time, especially around valuation effective date, valuation refresh, and material event update. We focus on what an analyst can produce, audit, and reuse when equity facts change.
Valuation effective date controls
Why it matters
Valuation effective date controls reduce ambiguity when the report needs a clear start date for the 409a valuation. That matters because equity decisions often depend on what was true on the effective date.
How to check
In a demo or sample workflow, ask where the effective date is entered and how it is stored. Then request an export that shows the effective date alongside the valuation report content.
Valuation refresh workflow
Why it matters
Valuation refresh workflow helps keep 409a valuation current without losing history. This is crucial when the business needs to show that prior valuations were superseded correctly.
How to check
Ask the product to show how it handles creating a new valuation set without overwriting the old one. Use a sample scenario and export both versions to confirm the system preserves prior outputs.
Material event update handling
Why it matters
Material event update handling keeps the 409a valuation process aligned when new facts arise. Buyers want to ensure the tool flags what changed and connects it to the updated valuation timeline.
How to check
Show a scenario with a changed equity fact set and ask what fields must be updated. Confirm the output indicates whether an update was triggered and what version it belongs to.
Reasonable valuation method documentation
Why it matters
Reasonable valuation method documentation is what analysts rely on when explaining why a 409a valuation outcome makes sense. If documentation is thin, the report is harder to defend and reuse.
How to check
Request a sample 409a valuation report export and look for explicit method notes, including which approaches were used. Ask whether the tool stores method notes as structured text or only free-form comments.
Assumption and input versioning
Why it matters
Assumption and input versioning protects the credibility of 409a valuation outputs as estimates evolve. It also helps auditors trace how a change to a key assumption affected the final report.
How to check
In a demo, change one key input in a valuation scenario and then regenerate the output. Verify the export keeps both the prior and current inputs linked to their respective versions.
Audit log for valuation edits
Why it matters
Audit log for valuation edits supports a defensible 409a valuation narrative. When multiple analysts touch the same package, a clear edit trail reduces disputes about what changed.
How to check
Ask to view an audit log for a sample valuation project after edits are made. Export the audit trail and check whether it records who changed what and when, linked to the valuation output.
Red flags
- Effective date is editable after export without version preservation
- Refresh or update overwrites prior 409a valuation outputs
- Exports omit method notes or fail to show input changes
Fit by situation
- If your team frequently runs new 409a valuations, prioritize valuation refresh workflow.
- If you expect frequent fact changes that could require an interim update, prioritize material event update handling.
- If multiple analysts revise the same package, prioritize audit log for valuation edits.
