Primary Capital vs Secondary Share Purchase

Primary capital is new money invested directly into the company, which the company uses for growth or operations. A secondary share purchase buys existing shares from an existing shareholder (a founder, early employee, or earlier investor) — the money goes to that seller, not to the company itself.

Secondary purchases in private companies are common as a way for early employees or founders to realize partial liquidity before a full exit, and can sometimes be negotiated at a discount to the primary round price, though the buyer should understand why the specific seller wants liquidity now.

The common failure is not asking why a specific individual is selling shares secondarily. A founder or early employee selling a small, planned diversification amount is very different from one selling because they've lost confidence in the company's prospects.

Before a secondary purchase, understand: the seller's specific stated reason for selling now; whether the price reflects a genuine discount to the current primary round or simply matches it; and whether the same information rights and governance terms available to primary investors in this round are also available to a secondary buyer.

A secondary purchase requires the same underwriting as a primary investment, plus one additional question: why is this specific seller choosing to sell now.
