A fixed percentage of ownership that remains constant regardless of new contributions in a dynamic equity model. Used for founders who bring IP, initial capital, or want to guarantee a minimum ownership stake. The rest of the equity pool adjusts dynamically while the protected portion stays locked.
protected equity
noun — In a dynamic equity model, a designated percentage of total ownership that is assigned to a specific founder or contributor and remains fixed regardless of future contribution activity from any team member. The protected percentage is set at the outset and documented in the operating agreement. It coexists with the dynamic equity pool, which distributes the remaining ownership based on tracked contributions over time.
Why it matters
Pure dynamic equity models can create anxiety for founders who have already made significant contributions before the tracking begins, such as building the initial product, investing seed capital, or bringing proprietary technology. Without protection, their early contributions could be diluted by ongoing time contributions from other team members.
Protected equity solves this by locking in a baseline ownership percentage that cannot be diluted by the dynamic portion. It provides certainty for founders who need it while still allowing the remaining equity to adjust based on ongoing contributions. This makes it easier to recruit co-founders who have made asymmetric early investments in the company's formation.
The concept also prevents the "contribution treadmill" problem that can arise in purely dynamic models — where a founder who contributes heavily in year one finds their percentage declining over time as other team members contribute more in later years. Protected equity recognizes that some value creation is front-loaded and should be permanently credited. See our article on when to convert dynamic equity to a cap table for related context.
How it works
The total equity is divided into two pools: a protected (fixed) portion and a dynamic portion. For example, a founding team might allocate 30% as protected equity and leave 70% to be distributed dynamically based on contributions. If the technical founder who built the MVP receives 20% protected equity and the business founder receives 10% protected equity, those percentages are locked.
The remaining 70% is then split among all contributors (including the founders) based on their ongoing tracked contributions. As the team grows and new people contribute, only the 70% dynamic pool is affected. The protected equity holders maintain their fixed percentages no matter what happens in the dynamic pool.
The specific percentages and rules should be documented in the operating agreement, including what happens to protected equity if the holder leaves, whether vesting applies to the protected portion, and whether the protected percentage can be adjusted by mutual agreement. Some teams phase out protected equity over time, gradually converting it into contributions within the dynamic pool. This hybrid approach is more flexible than a fully fixed split and more reassuring than a fully dynamic one.
| Model | How equity is set | Best for |
|---|---|---|
| Fixed split | All percentages set at founding, never change | Teams with equal commitment and equal early contributions |
| Pure dynamic | All equity earned through tracked contributions | Teams starting from scratch with no prior IP or capital |
| Protected + dynamic | Some equity fixed, remainder earned dynamically | Teams where some founders made significant pre-formation contributions |
History and origin
Protected equity as a formal concept emerged from the dynamic equity movement in the 2010s, most notably through Mike Moyer's Slicing Pie model, which introduced a principled framework for dynamic equity in startups. Moyer's model initially focused on pure dynamic allocation, but practitioners quickly recognized that founders who had already invested significant value before the model began needed a mechanism to protect that prior investment.
The idea of protecting certain equity stakes from dilution has older roots in partnership law, where senior partners often had guaranteed minimum profit shares regardless of junior partner activity. The application to startup dynamic equity models formalized these intuitions into a structured tool.
Today, protected equity is increasingly common in LLCs and early-stage companies that use dynamic equity tracking tools. It represents a pragmatic middle ground between the simplicity of fixed splits and the fairness of fully dynamic models. As dynamic equity becomes more mainstream, protected equity provisions are becoming standard in operating agreements designed for contribution-tracking models.
Frequently asked questions
What is protected equity?
Protected equity is a fixed percentage of ownership in a dynamic equity model that is locked in for a specific founder or contributor and cannot be diluted by ongoing contributions from other team members. It sits outside the dynamic equity pool and remains constant regardless of how much other contributors work.
When should a founder use protected equity?
Protected equity is appropriate when a founder brings significant pre-existing value to the venture — such as intellectual property, a functioning product, substantial seed capital, or a customer relationship — that would be unfairly diluted in a purely contribution-based dynamic model. It's also useful when one founder needs psychological certainty about a minimum stake to commit to the venture.
How does protected equity interact with the dynamic pool?
The company's total equity is divided into two buckets: the protected (fixed) portion and the dynamic portion. Protected equity percentages are locked and never change based on contributions. The dynamic pool is the remaining equity that gets distributed based on tracked contributions over time. Both pools can coexist in the same company structure.
Does protected equity vest?
This is a design choice that should be specified in the operating agreement. Some teams apply vesting to protected equity to guard against a founder leaving early with their full protected stake. Others treat protected equity as immediately vested in recognition of contributions already made. The right approach depends on when the protected equity is being recognized and whether the underlying contributions have already occurred.
Can protected equity be adjusted after it's set?
Yes, but only by unanimous or majority agreement of the team, as specified in the operating agreement. Some teams build in periodic reviews where protected equity allocations can be revisited by mutual consent. Changes to protected equity should always be documented in a formal amendment to the operating agreement.
What happens to protected equity if a founder leaves?
This depends entirely on what the operating agreement specifies. If protected equity is unvested, it may be forfeited or subject to buyback. If it's vested, the departing founder typically retains it. Some agreements have different rules for voluntary departure vs. termination for cause. This is one of the most important provisions to define clearly before anyone leaves.
Is protected equity the same as a fixed equity split?
No. A fixed equity split allocates all the company's equity in fixed percentages among founders with no dynamic component. Protected equity is a hybrid — some equity is fixed (the protected portion), and the rest is distributed dynamically based on contributions. Protected equity allows the benefits of a dynamic model while providing certainty for founders with significant pre-existing contributions.
