What Happens When A Founder Leaves A Startup?

A founder leaving triggers a series of practical and legal questions: Who owns what? What happens to the shares? How will responsibilities be reallocated? These questions are addressed by core legal documents: Articles of Association or Vesting agreement . Let’s unpack this a little further.

Essential Steps After a Founder Leaves

Step one: Decide what kind of exit this really is – Are they leaving as a GOOD Leaver or a BAD Leaver?

What is a Good Leaver?

§   Founder leaves without any fault

 

Example: Death, permanent incapacity, they are wrongfully terminated

What is a Bad Leaver?

§   Founder leaves where they have don something wrong

 

Example: Gross misconduct, criminal offences like fraud or other termination with cause

 

Once you know which kind of Leaver you’re dealing with, the next step is figuring out what happens to their shares.

Shares of Good Leaver

§   Required to transfer their vested shares at market value or

§   Allowed to retain their vested shares

Shares of Bad Leaver

§   Required to transfer their vested shares at nominal value but

§   Board/ company has discretion in deciding it.

But this raises a few important questions:

1.        What exactly are vested shares?

Vesting is the process through which employees (or founders) earn their right to own shares over time. Instead of receiving all their shares at once, they “vest” gradually based on the company’s vesting criteria and schedule. These usually outlined in a Vesting Agreement.

 

2.        How does the process actually work in real life?

Usually, they are set out in the Company’s Articles on how shares are transferred. It could be shares buy-back, shares moving to an option pool, shares reallocation, shares offered to existing shareholders. In Bad Leaver cases, shares are often converted to worthless deferred shares to avoid tax complications.

3.        How are shares transferred?

The Company’s Articles set out exactly what happens when a founder leaves: whether the company buys back the shares, moves them into an option pool, or reallocates them to a new hire.

 

4.        How much discretion does the Board or company really have in all this?

The Board often has some flexibility in deciding how leaver provisions are applied, especially in borderline cases, but their powers are ultimately guided (and limited) by what’s written in those documents. It’s usually set out in the Company’s Articles.

So it’s pretty clear. Your Vesting Agreement and Company’s Articles aren’t just paperwork you sign and forget. They’re the backbone of how your startup deals with tough moments. When a founder leaves, they determine who owns what, how shares are handled, and how fairly everyone is treated.

What Should I Include In Vesting Agreement?

It should specifically outline these components:

Equity details

§   The exact number of shares, stock options…

§   Their exercise price

Vesting Schedule

§   Timeline and condition

§   Monthly or quarterly vesting

The Cliff Period

§   Timeframe where no shares vest

Milestone Conditions

§   This specifies performance metrics the employee must hit to unlock their shares

Leaver Provisions

§   Clear definitions of “good leaver” or “bad leaver”

§   Indicates whether the company can repurchase unvested shares at nominal price

Transfer restrictions

§   Prohibiting selling or transferring unvested shares.
