Founder

TL;DR

A person who started or co-started the company and (typically) holds founder common stock subject to founder vesting.

A founder is one of the original creators of the company. The legal definition matters because founder shares are typically structured differently from later employee grants — often common stock granted at incorporation, subject to founder vesting, and eligible for QSBS tax treatment in the US after a 5-year hold.

Founder status is also a cultural designation that shapes how the company is described, how the team is recruited, and how investors price the deal. Companies typically have 1–4 founders; teams larger than 4 often have 'founding team members' rather than additional founders.

Worked example

A solo founder writes the first MVP in 4 weekends, signs the first 3 customers personally, hires the first engineer using a 1.5% equity offer, and continues to be CEO through a $30M Series B at month 30 — owning ~52% post-Series-B.

Common pitfalls

• Adding 'founders' after the company is well-established and creating cap-table complexity.
• Failing to formalize founder vesting and cofounder agreements early.
• Letting founder titles drift in ways that confuse investors and employees.
