CartaX reshaping private liquidity
Ani Banerjee, co-founder of Andromeda Group, on secondary diligence and companies staying private
CartaX mattered because it tried to turn private stock trading from a broker driven scavenger hunt into a company run market with rules, data, and repeatability. That shifts the center of power toward the issuer. The company can decide who gets on the cap table, how often shares trade, and how much stock can move, while using auctions to get cleaner price discovery than one off brokered deals or infrequent tenders.

The practical unlock is settlement and workflow, not just matching buyers and sellers. Because Carta already held the cap table, transfer restrictions, shareholder history, and transfer agent function, it could automate steps that usually take weeks or months of lawyers, ROFR waivers, and manual cap table updates.

CartaX sat in a different bucket from Forge and EquityZen. Those platforms mainly helped smaller blocks trade through marketplace or fund structures. CartaX and Nasdaq Private Market were built more like issuer controlled liquidity programs, where the company runs the event and keeps tighter control over buyers and disclosures.

The deeper implication was not just more liquidity, but better feedback loops. Regular auctions could tell a company what institutional buyers would actually pay for common stock, help anchor the next primary round, and let management refine disclosures and investor messaging before an IPO or direct listing.
The market is heading toward more structured private liquidity, but with issuer control staying central. The winning model is likely to look less like a fully open exchange and more like recurring, tightly governed trading windows that give employees and investors some liquidity while letting companies stay private longer and shape their shareholder base deliberately.
