Carta Consolidating Equity Infrastructure
Carta Series C Deal Memo
The real opening was not that incumbents were weak on paper, it was that equity administration for public companies was still stitched together from transfer agents, brokers, and manual back office work instead of one software system. Carta already owned the private company cap table, 409A, and tender workflow, so moving upstream meant selling the same system of record into companies approaching IPO, then replacing fragmented providers like Computershare and AST with one workflow for ownership records, employee equity, transfers, and liquidity.

Legacy public market providers mostly handled narrow jobs. The deal memo frames Computershare, AST, and brokerage partners as separate vendors for registry, ESOP administration, transactions, and dividends. The opportunity was to collapse those handoffs into one product, which mattered most for Carta customers already planning to go public.
-
Carta had an important structural advantage because the hard part in private markets was not just matching buyers and sellers, it was keeping the ledger clean. By 2020, Carta managed about a third of venture backed company cap tables and had built transfer, restrictions, and tender workflows directly on that record, which made adjacent products easier to add.
-
The market was scarce because private liquidity infrastructure barely existed at all. The ecosystem was still dominated by lawyers, Excel, brokers, and point solutions, and even in 2024 the discussion around Carta still treated Computershare and similar public market incumbents as dinosaur style products that were painful to use and slow to modernize.
Going forward, the winning company in equity infrastructure is likely to look less like a broker and more like the operating system underneath ownership. That favors platforms that first become the source of truth for shares, then layer on transfers, tenders, fund admin, compensation, and eventually public company workflows as customers mature.
