CartaX trains issuers for public markets
James McGillicuddy, head of strategy at Carta, on building an issuer-centric platform and investing in secondaries
CartaX is really a training ground for investor relations before an IPO. A company that runs recurring private liquidity events has to start producing cleaner disclosures, define who can buy and sell, and let outside investors test its valuation in a controlled setting. That forces the finance team, legal team, and leadership to build the habits of a public company, without fully giving up cap table control or opening the stock to daily public volatility.

The core muscle being built is regular disclosure. CartaX was designed around companies setting a cadence for board materials, financial updates, KPI sharing, and investor communications, often quarterly, so the same operating rhythm starts to resemble public company reporting.
-
The second muscle is price discovery. Instead of waiting for a fundraising round every 12 to 24 months, companies can see what institutional buyers will actually pay for common shares, then use that signal to sharpen fundraising, compensation, and IPO planning.
-
This is why CartaX sits closer to Nasdaq Private Market than to Forge or EquityZen. The issuer controls participants, disclosure scope, and transaction rules, which makes the product less like an open bazaar for stock and more like a company run pre public market.
Over time, this model points toward a larger class of privately traded companies that behave more like public companies long before listing. The winners will be the ones that can pair private market control with public market discipline, then choose an IPO or direct listing from a position of much stronger price credibility and operating readiness.
