What this means for your stock
Institutional investors like 40 North Ventures typically hold preferred shares with rights that differ from the common stock or options held by employees. In a liquidity event, preferred shareholders may have liquidation preferences, anti-dilution protections, or board-level governance rights that affect the value of common equity. The specific terms depend on each company's funding agreements.
Secondary market considerations
Some venture-backed companies allow employees to sell shares on secondary markets, while others restrict transfers. Whether your company permits secondary sales, and under what conditions, is typically governed by the company's equity plan and any applicable right-of-first-refusal provisions — not by the fund itself. However, the presence of institutional investors can sometimes signal the maturity and governance structure of the company.
