Founder

Also called: Startup 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 to 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.
