Startup vesting and leaver matters: How to Prepare
Vesting, leaver clauses and milestones in practice
In short: If a founder's departure hasn't been agreed in advance, the leaver keeps all their shares. Preparing for it takes three aligned documents: the shareholders' agreement, the option plan terms, and employment and managing director agreements. Milestone-based vesting only works if each milestone is measurable, dated and assigned to a specific person, with a named party who confirms it. Startup vesting and leaver matters are discussed in this article.
Why is planning for a founder exit now standard practice?
Founders usually assume everyone will stay until the exit. The market has already adjusted to the fact that this rarely happens. The shift shows in three ways.
Early leaver is now a standard term. Alongside good and bad leaver, a middle category has emerged for someone who leaves on good terms, but early.
Option plans come in two parts. The grant decision is registered with the Finnish Trade Register, while vesting and departure scenarios are set out in separate plan terms.
Legislators have responded. The reform of the Finnish Limited Liability Companies Act, taking effect in July 2027, allows the articles of association to include a right of first refusal alongside the redemption clause. It binds all shareholders, including those outside the shareholders' agreement.
The common thread: ownership is tied to contribution, and turnover is planned for in advance.
Why is a departure so hard to handle after the fact?
The reason for leaving is rarely dramatic. Life or focus changes, the company grows into a different job than the one they signed up for, or another opportunity comes along. Even so, it feels personal on both sides.
For the leaver, ownership is proof they were there when there was nothing: the unpaid months, the personal guarantees, the better-paid job they gave up. For those staying, it looks like the leaver is profiting from their work. Investors, too, generally don't want to see large stakes held by people no longer involved.
Both views are understandable, which is exactly why the moment of departure is the worst time to set the rules. A leaver clause agreed in advance isn't a sign of distrust. It's a promise that a departure won't turn into a dispute.
What happens if nothing has been agreed?
The shares stay with the leaver. Finnish company law offers no mechanism for departures, so everything depends on contracts. The consequences show up in four ways: dilution falls on those still building, decision-making can stall on minority rights, the cap table is hard to explain to a new key hire, and in a funding round or exit, this is the buyer's first question.
Which documents do you need for startup vesting and leaver matters?
Preparation means three agreements that must say the same thing.
The shareholders' agreement sets the vesting schedule, leaver categories, pricing per category and the order of purchase rights. What matters is who decides the category and on what criteria.
Option plan terms. Unexercised options usually lapse on departure, but exercised ones are already shares and fall under the shareholders' agreement. This is where documents often fail to align, since each has its own leaver definition. Separate documents also get updated, and forgotten, separately.
Employment and managing director agreements. Employment law has no concept of a leaver. A dismissal can be entirely lawful even if the person is a good leaver under the shareholders' agreement, and vice versa. A managing director is not an employee under Finnish law and needs a separate agreement.
How should milestone-based vesting be defined?
Time-based vesting (for example, four years with a one-year cliff and monthly accrual) is simple, but it rewards presence rather than results. Milestone vesting fixes this, provided each milestone can be confirmed as met without interpretation. Each milestone must be:
measurable
dated
assigned to a specific person
confirmed by a named party.
Also agree how milestones are updated (for example, annually by board decision) and what happens if no agreement is reached on new ones. Otherwise vesting ends up tied to outdated goals. The most workable model is often a hybrid: a time-based foundation with a performance-based layer on top.
The most common mistakes
Nothing has been done. At founding it feels like distrust, and later it can't be agreed because someone would lose out.
No valuation method. If the agreement just says "fair value," you've agreed to a dispute. Agree on a calculation method, a valuer, or both.
Roles aren't described. Without a written role, there's no way to assess whether someone fulfilled it, and leaver classification comes down to gut feeling.
The documents conflict. Then whichever is later and more specific prevails, which in practice means chance.
Clauses are unclear. A clause whose application can reasonably be disputed is effectively no clause at all.
Checklist
Read the leaver provisions of your shareholders' agreement, option terms and employment agreements side by side. Test every milestone with one question: could we objectively agree whether this was met? Document key people's roles and goals alongside the shareholders' agreement.
A leaver situation is easy to agree on when everyone sits on the same side of the table. Not when someone is already heading for the door.
FAQ
What do good, bad and early leaver mean? The categories determine the terms and price at which a leaver's shares are bought back. A good leaver leaves for an acceptable reason, a bad leaver for example due to a breach, and an early leaver on good terms but early. The exact definitions are set in the shareholders' agreement.
What is a vesting cliff? A period, typically one year, after which the first portion of equity vests. Someone who leaves before the cliff earns no vested shares at all.
When should leaver terms be agreed? At founding. At that stage they're neutral contract terms; later, every change becomes a negotiation someone loses.
