GMV or Net Revenue: Which Number Sets Your Strike Price

Gross merchandise value counts every dollar transacted through the platform, most of which flows straight through to sellers or suppliers and was never the marketplace's own revenue to begin with. It's a legitimate way to communicate scale and momentum to investors, but treating GMV growth as equivalent to revenue growth in a 409A would produce a valuation the business can't actually support, since the marketplace's own economics depend on take rate, not total volume.

Net revenue, GMV multiplied by your effective take rate, is what a defensible valuation should be built on, along with how that take rate has trended as the marketplace has scaled. A rising take rate as the platform adds value-added services signals a healthier trajectory than flat or declining take rate paired with GMV growth, and an appraiser should be asking specifically about that trend, not just the top-line volume number.

The tension shows up concretely when a new hire compares the GMV figure from your investor deck against the strike price on their offer letter and the math doesn't obviously connect. Explain the difference plainly rather than letting people assume the smaller number means the business is smaller than advertised; a healthy take rate on a large GMV base can still produce a solid, defensible valuation even though it's nowhere near the headline volume figure.

Keep both numbers visible and clearly labeled in your own internal reporting, GMV for scale and momentum, net revenue and take rate for anything tied to equity value, rather than defaulting to whichever number is more flattering in a given conversation. Consistency matters more than which framing you lead with: an investor who later sees the 409A and a new hire who later sees the pitch deck should both recognize the same underlying business, described honestly from two different angles.

To reconcile the two numbers without misleading anyone:

• Report GMV for scale and momentum, and net revenue and take rate for anything tied to equity value, labeling both clearly.
• Show how your effective take rate has trended as the marketplace added value-added services, since the trend matters to an appraiser.
• Build a one-page bridge from GMV through the blended take rate to net revenue, listing adjustments such as refunds, payment processing costs and promotional credits.
• Explain the difference plainly to new hires who compare a fundraising deck's GMV with the strike price on their offer letter.

A single-entity marketplace still refining its take rate and extending options to an early engineering and ops team fits Carta's straightforward workflow well. A marketplace expanding into adjacent verticals or geographies through separate legal entities, each with its own take rate and regulatory considerations, benefits more from Shareworks' capacity to track equity across a more segmented structure without collapsing distinct businesses into one undifferentiated view.

Say a candidate saw a large GMV figure in your fundraising deck and is surprised their offer letter's strike price implies a much smaller company. Walk them through the actual take rate and net revenue trend directly, ideally with the last few quarters shown, rather than waving the question away. Most candidates find a transparent explanation reassuring rather than alarming, since it demonstrates the finance function actually understands its own numbers, which says something about the company beyond the specific figure being discussed.

Say your board wants a one-page view that ties GMV directly to the 409A's net revenue figure, rather than seeing the two numbers appear in different documents with no visible connection. Build a simple bridge: start with GMV, apply the blended take rate to get net revenue, then show any adjustments, refunds, payment processing costs, or promotional credits, that separate net revenue from what actually flows to the bottom line. That bridge, included as an appendix to the valuation report itself, gives directors a clear line of sight from the number they hear about in investor conversations to the number that actually drives the strike price.

This same bridge is useful well beyond the boardroom. Finance can hand it to a new hire who asks a sharp question about the gap between the fundraising deck and their offer letter, and it holds up better than a verbal explanation because it shows the actual math rather than asking someone to just trust that the difference is legitimate. Keep the bridge current every time take rate shifts meaningfully, since a stale reconciliation is nearly as confusing as having none at all.
