Vesting

Milestone Vesting Explained

Milestone vesting releases equity when specific performance targets are met, such as revenue goals or product launches, instead of purely on the passage of time.

Trigger
Achieving a defined milestone, not time alone
Common use case
Advisors, consultants, some executive grants
Main risk
Disputes over whether a milestone was actually met
Often combined with
A time based schedule as a backstop

Performance based triggers for equity release

Instead of, or alongside, a time based schedule, milestone vesting ties equity release to achieving specific, objectively measurable goals. Examples include hitting a revenue target, closing a specific partnership, launching a product, or completing a funding round. The grant document defines each milestone clearly and specifies what percentage of the grant vests when it is achieved, layered on top of, or instead of, a standard vesting schedule and typically used alongside stock options rather than founder shares.

Outcome rewards compared to tenure based earning

  • Pro: directly rewards outcomes rather than tenure, which can suit advisors or specialist consultants.
  • Pro: can motivate focus on specific goals that matter most to the business at that stage.
  • Con: milestones can become outdated if the business strategy shifts, leaving the grant stuck.
  • Con: disputes can arise over whether a milestone was genuinely met, especially with vague wording.
  • Con: harder to value for tax and accounting purposes than a simple time based schedule.

Applicability to advisor and executive role grants

Milestone vesting is most common for advisors and consultants who contribute to specific outcomes rather than day to day work, and for some executive hires where the board wants pay tied closely to results. It is less common for broad based employee grants, where a simple time based schedule is easier to administer fairly across the whole team than layering in accelerated vesting triggers.

Questions on tying equity to milestones

Can milestone and time based vesting be combined?
Yes. A common structure ties most of the grant to time and a smaller portion to specific milestones, reducing dispute risk while still rewarding key achievements.
Who decides if a milestone has been met?
Usually the board, based on criteria defined in the grant agreement. Vague or subjective milestones increase the risk of disagreement.
Is milestone vesting common for founders?
It is less common than time based reverse vesting for founders, though some deals use milestones for specific tranches, such as an earn-out linked grant.
