Curated 10 to 20 Investor Whitelist
Alessandro Chesser, former VP of Sales at Carta, on the dynamics of CartaX auctions and preparing for liquidity
A small, curated buyer list is what turns a private stock auction from a brokered sale into company controlled price discovery. The point is not to invite every possible buyer. It is to invite the specific investors most likely to bid seriously, clear meaningful size, and fit the company’s desired cap table. CartaX was built around issuer control, with companies choosing who can buy, how often auctions run, and how much stock can trade, while recurring auctions create a cleaner market signal than one off tenders.

The whitelist is effectively cap table design. Companies already start with existing investors and known interested buyers, then add a short list of outside institutions whose check size, hold period, and company preferences match the issuer. That is meant to bring in buyers who will actually compete, not just browse a data room.

This is a direct contrast with traditional tenders and brokered secondaries, where banks or brokers often steer allocation toward the biggest fee generating buyers. In the issuer controlled model, the company can exclude misaligned investors, include strategic long term holders, and use the auction to refresh the cap table without issuing new shares.

Keeping the list to roughly 10 or 20 investors also reflects market mechanics. Private auctions need enough demand for competition, but not so many buyers that the process becomes noisy, slow, or leaks sensitive information. The broader private liquidity market still runs on issuer approval and controlled disclosures, not open market volume.
Over time, the winning platforms in private liquidity are likely to look less like open exchanges and more like software that helps companies repeatedly run these tightly managed auctions. As recurring liquidity becomes normal, the whitelist becomes a strategic lever for shaping ownership, building a pre IPO investor base, and establishing a credible trading history before a tender, primary, or public listing.
