When you’re building a startup, equity can be one of the most powerful tools you have.
It can help you attract talented people before you can pay “big business” salaries, align your team around growth, and keep founders and key hires committed for the long haul.
But equity can also create real risk for your business if it’s handed out too early, in the wrong structure, or without the right documentation.
That’s where a vesting cliff (sometimes called cliff vesting) comes in.
A vesting cliff is a practical mechanism startups use to protect the business if a founder or employee leaves early, while still offering meaningful upside to people who stay and build.
Below, we’ll walk you through how a vesting cliff works in Australia, why it matters from a business owner’s perspective, and how to document it properly so you can scale with confidence.
What Is A Vesting Cliff (And How Does It Work In Practice)?
A vesting cliff is a minimum period someone must remain with the business before they “earn” (vest) any equity.
Until the cliff is reached, none of the equity vests. Once the cliff is reached, a chunk vests at once, and the remainder typically vests gradually over time.
A Simple Example Of A Vesting Cliff
One common arrangement is:
- 4-year vesting schedule
- 1-year vesting cliff
- Monthly vesting after the cliff
In that setup:
- If someone leaves at 11 months, they vest 0% of the equity.
- If they stay to 12 months, they might vest 25% at the cliff (because 1 year out of 4 years has been “earned”).
- After that, the remaining 75% vests monthly (or quarterly) over the remaining 3 years.
From a business perspective, the cliff is a safeguard: it reduces the chance you end up with “dead equity” held by someone who didn’t stay long enough to meaningfully contribute.
Is A Vesting Cliff Only For Employees?
No. A vesting cliff is very common for:
- Founders (especially where there are multiple co-founders)
- Key employees (often leadership or technical hires)
- Advisers (though adviser schedules are often shorter)
Where founders are involved, vesting is usually part of the “founder equity” arrangement from day one, particularly if you plan to raise capital later. Investors will often ask whether founder equity is subject to vesting and whether there’s a vesting cliff.
If you issue shares (or options) upfront with no vesting, and someone leaves early, they may keep a meaningful stake permanently. Even if that person is no longer involved, they could still:
- hold voting rights (depending on the share class)
- need to sign shareholder approvals for certain actions
- be entitled to proceeds on an exit
- create complexity when new investors come in
A well-designed vesting cliff helps your startup avoid those problems before they happen.
Why Your Startup Might Need A Vesting Cliff
Equity is a long-term incentive. The vesting cliff is what makes that incentive commercially fair for the business.
Here are the main reasons startups use vesting cliffs in Australia.
1. It Protects The Business From “Early Leavers”
Startups change quickly. Sometimes a co-founder isn’t a fit, or a key employee leaves within months.
Without a vesting cliff, your business can end up “stuck” with equity in the hands of someone who contributed only briefly. That can be hard to unwind later and can frustrate future hires and investors.
2. It Supports Future Capital Raising
When you raise capital, investors typically want comfort that:
- founders are committed for a meaningful period
- the cap table won’t become messy
- there are mechanisms to deal with departures
A sensible vesting cliff (properly documented) can make your business easier to invest in because it signals you’ve thought about long-term alignment and governance.
3. It Creates Clear Expectations Internally
Equity can be emotional. People often attach a lot of meaning to it.
A vesting cliff helps you set clear expectations: equity is earned through continued contribution, not just by signing an offer letter.
This is particularly important where you’re offering equity as part of a broader package, alongside salary, bonuses, or commission-based incentives.
4. It Helps You Avoid “Dead Equity” That Blocks Growth
Even small equity holdings can create practical issues later, especially if you need approvals, signatures, or buybacks.
In a growing company, you generally want equity to be held by people who are actively contributing to building the business.
The vesting cliff helps keep your cap table “alive” and aligned with your current team and strategy.
How Do You Structure A Vesting Cliff For Founders And Employees?
There isn’t a one-size-fits-all vesting cliff. The right approach depends on your business stage, your hiring market, your funding plans, and how you’re actually granting equity (shares, options, or another arrangement).
That said, there are a few key building blocks we typically help startups think through.
1. Decide What’s Being Granted: Shares, Options, Or A Different Arrangement?
In Australia, startups often choose between:
- Issuing shares (ownership now, potentially with restrictions or buyback rights)
- Granting options (a right to acquire shares later, often used to align with vesting)
- Phantom equity / sweat equity-style arrangements (economic exposure without shares in some cases)
Each approach has different tax, governance, and administrative consequences. For example, employee equity issued under an Employee Share Scheme (ESS) may have specific tax rules and eligibility requirements. The right approach often depends on your circumstances, so it’s important to speak with an accountant or tax adviser before you finalise an equity structure.
For founder arrangements, you might use a Share Vesting Agreement that sets out the vesting schedule (including the vesting cliff) and what happens if a founder leaves.
For employees, many startups use an employee equity plan framework (particularly where you’ll have multiple grants over time). This can sit alongside an Employment Contract so the equity terms don’t get mixed up with day-to-day employment conditions.
2. Set The Vesting Schedule And The Vesting Cliff
Common choices include:
- Vesting cliff length: often 6-12 months (1 year is very common)
- Total vesting period: often 3-4 years (4 years is very common)
- Vesting frequency: monthly, quarterly, or annually after the cliff
From your business perspective, the question isn’t “what looks standard?”, it’s:
- How long does it take for a person to meaningfully contribute in this role?
- How quickly do you want to reward retention?
- How much “unvested” equity do you need available if the person leaves and you need to hire a replacement?
3. Define What Happens If Someone Leaves (Good Leaver vs Bad Leaver)
This is one of the most important parts, and it’s where many startups accidentally create disputes.
Typically, your documents should address:
- Unvested equity: does it lapse automatically? Is it bought back? Is it cancelled?
- Vested equity: can the person keep it, or does the company have buyback rights?
- Price mechanics: if there’s a buyback, how is the price determined?
You’ll also often see “leaver” concepts such as:
- Good leaver (eg redundancy, serious illness, termination without cause)
- Bad leaver (eg serious misconduct, breach of restraints/confidentiality, fraud)
Good leaver / bad leaver definitions need to be drafted carefully to match your business realities and reduce ambiguity.
It’s also important to note that what a company wants to happen on departure (for example, “forfeiture” of shares or a compulsory buy-back) doesn’t always map neatly onto what’s legally possible in practice. Depending on the structure, the Corporations Act and your governing documents can affect how share transfers, cancellations, or buy-backs must be implemented (including approvals and procedural requirements). Getting the mechanics right upfront is key.
4. Consider Acceleration Triggers (But Use Them Carefully)
Some startups include acceleration clauses. For example:
- Single-trigger acceleration: vesting accelerates on a sale of the company
- Double-trigger acceleration: vesting accelerates if there’s a sale and the person is terminated (or resigns for certain reasons) within a set period
Acceleration can make equity offers more attractive, but it can also dilute founders and investors earlier than expected.
It’s worth thinking through how acceleration impacts your cap table at the exact time you’re trying to close a deal (when buyers and investors are often most sensitive to dilution).
5. Make Sure Your Company’s Governance Can Support The Arrangement
Equity arrangements don’t exist in isolation. They sit within your company’s governance framework.
For example, your Company Constitution may need to align with (or at least not contradict) your vesting terms, share transfer restrictions, and any buyback mechanisms.
If you have multiple shareholders (or plan to), a Shareholders Agreement is also commonly used to set the rules of the relationship between owners, including decision-making and what happens when someone exits.
What Legal Documents Do You Need To Implement A Vesting Cliff Properly?
A vesting cliff is only as strong as the documents behind it.
If your arrangements are informal (or spread across emails and messages), you might find that the cliff is difficult to enforce when it matters most.
Here are the legal documents Australian startups commonly use to implement vesting cliffs in a practical, business-friendly way.
- Share Vesting Agreement: commonly used for founders, setting out the vesting cliff, vesting schedule, and what happens on departure. This is often essential where founder equity is issued upfront. (For many startups, a Share Vesting Agreement is the key document that makes the cliff enforceable.)
- Option Deed: where equity is provided through options, an Option Deed can set out vesting conditions, exercise price, expiry, and what happens if employment ends.
- Employee Share Scheme (ESS) documents: if you’re offering equity broadly to employees (and you want a repeatable process), an Employee Share Scheme can provide a structured framework for multiple grants, including consistent vesting cliff terms. ESS arrangements can also involve specific tax treatment and compliance steps, so it’s important to get tax advice on how an ESS may apply to your company and participants.
- Employment Contract: for employees receiving equity, your Employment Contract should clearly cover the employment relationship (pay, duties, confidentiality, IP) while referencing the separate equity documents where appropriate.
- Company Constitution / Shareholders Agreement: these documents help ensure your company can actually implement transfers, restrictions, and exit mechanics. A Shareholders Agreement is especially useful where there are multiple owners and you need clear governance rules.
- Sweat equity or alternative incentive documentation: where you’re rewarding contribution in a non-standard way (common in early-stage startups), a properly documented Sweat Equity Agreement can help set expectations and reduce disputes.
Not every startup needs every document on day one. But if you are using a vesting cliff to protect your cap table, it’s important the legal structure matches the commercial intent.
Common Vesting Cliff Mistakes That Can Hurt Your Business Later
Most vesting cliff problems don’t happen when everything is going well. They happen when someone leaves, a dispute starts, or you’re mid-way through fundraising and due diligence begins.
Here are some common issues we see (and how you can avoid them early).
1. “We Agreed It Verbally” (But It’s Not Documented)
A vesting cliff is fundamentally contractual.
If your cliff terms aren’t properly captured in a signed document, you risk ending up in a dispute about what was agreed, when it started, and what happens on departure.
From a business owner’s perspective, that uncertainty is costly - it can slow down fundraising, complicate exits, and increase the likelihood of negotiation under pressure.
2. Using The Wrong Vehicle For The Outcome You Want
Sometimes businesses issue shares immediately when what they really wanted was a vesting-based incentive.
Other times, businesses grant “options” informally without a clear deed or plan, leaving uncertainty about vesting, expiry, exercise price, and termination outcomes.
It’s worth getting clarity upfront: do you want someone to be an owner now, or earn ownership over time?
3. Not Aligning Vesting With Termination And IP Protections
Equity is only one part of the picture. You also want to protect:
- your confidential information
- your customer relationships
- your intellectual property (IP)
If an employee leaves before the vesting cliff and takes valuable know-how with them, you want the employment and IP clauses to be strong and enforceable - not just the equity terms.
4. Unclear “Good Leaver / Bad Leaver” Definitions
If your leaver definitions are vague, they can invite disputes.
For example, what counts as “cause”? What happens if someone resigns due to burnout? What if performance is poor but not misconduct?
It’s better to define these concepts clearly and tie them to your actual processes, so you can apply them consistently.
5. Forgetting About Administration (Cap Table, Board Approvals, ASIC Paperwork)
Even the best vesting cliff can become messy if your administration doesn’t keep up.
Depending on your structure, you may need to manage:
- option registers and grant letters
- board and shareholder approvals
- share issues or share transfers
- updating your cap table and internal records
Good documentation helps, but so does having a clear process for how grants are approved and recorded.
Key Takeaways
- A vesting cliff is a minimum period someone must stay with your startup before any equity vests, helping protect your business from early departures.
- For many startups, a 1-year vesting cliff within a 3-4 year vesting schedule is a common structure, but your best option depends on your business goals and hiring strategy.
- Founder vesting cliffs can help keep your cap table clean and investor-ready, especially when you plan to raise capital or scale quickly.
- Your vesting cliff should clearly deal with what happens on exit (including unvested equity, buybacks, and good leaver/bad leaver scenarios) and be structured in a way that is workable under your governing documents and applicable legal requirements.
- The right documents matter - a vesting cliff usually needs properly drafted agreements (not just informal promises) to be enforceable and practical.
- Getting the structure right early can save significant time, cost, and friction during fundraising, hiring, and exits.
