Legal Guide
What goes in a founder agreement?
Equity percentages are just the start. A shareholders' agreement protects every founder — including from each other.
Equity vesting schedules
A standard 4-year vest with a 1-year cliff protects the company if a founder departs early.
Roles and decision-making
Define who has authority over product, finance, hiring, and other key decisions.
IP assignment
All IP created for the company must be formally assigned — including pre-existing work.
Departure & buyout terms
What happens to a departing founder's shares? Right of first refusal and drag-along clauses matter.
Non-compete clauses
Restrict founders from competing or poaching employees after exit (with Ontario restrictions noted).
Dispute resolution
Define how deadlocks are broken — mediation, arbitration, or a casting vote.
