Minority Interest Valuation for a VC-Backed Professional Technology Platform
On minority interest valuations
Owning a small stake in a private company is not like owning shares on an exchange. There is no price to look up, no ready buyer, and often no obvious exit. What a minority interest is actually worth depends on the underlying business, the restrictions on transferability, and an honest accounting of how hard it would be to turn that stake into cash. Getting it right requires both rigorous methodology and the judgment to ignore data that looks relevant but isn’t.
The problem
A shareholder needed an independent valuation of a 0.2% stake in a late-stage, venture-backed professional technology platform — over $200M in annual revenue, institutional investors behind it — to support a time-sensitive personal financial decision.
The complication: the prior two years had seen institutional investors in comparable private holdings publish markdowns that were creating noise in the market.
Everyone had a number. No one had methodology.
Cutting through the noise
We started by setting aside what couldn’t be relied upon. The institutional markdowns were reviewed in detail and explicitly excluded — they lacked company-specific disclosure, observable market transactions, or disclosed methodology. Using them would have produced an artificially depressed value with no analytical foundation.
The valuation was anchored in EV/Revenue multiples from publicly traded comparable companies and recent private transactions in the professional technology platform sector — observable, supportable, and directly comparable to the company’s growth profile. A discounted cash flow was considered and set aside: for a high-growth, reinvestment-driven business with limited long-term cash flow visibility, a revenue multiple approach was simply more defensible.
A Discount for Lack of Marketability of 10% was applied — reflecting transfer restrictions, the absence of a secondary market, and exit timing uncertainty — partially offset by the company’s institutional backing, revenue scale, and trajectory. Each input was documented and supportable.
The conclusion
Fair market value: approximately $6.9M (base case), with a range of $5.5M to $7.4M. Delivered on deadline. The analysis withstood review by the shareholder’s legal and financial advisors.
