Your startup just got its first term sheet. The investor’s lawyer sends over due diligence requests. One of them: “Please provide your cap table.”
You realize the dynamic equity split you’ve been running for 18 months needs to become a fixed number. Now what?
Dynamic equity is great for the messy early days. Everyone’s contribution is different. No one knows what the company will become. A flexible model makes sense.
But at some point, you may need to lock it in. The question is when, and whether you need to at all.
Why Dynamic Equity Might Have an Expiration Date
Dynamic equity works because it adapts. Ownership shifts based on who’s actually contributing. That flexibility is a feature when you’re figuring things out.
For some companies, it stays a feature forever. Bootstrapped businesses with stable founding teams can run dynamic equity indefinitely. If contributions are still varying and everyone’s comfortable with the model, there’s no rule that says you have to stop.
But certain situations make flexibility less useful than certainty.
Investors want to know exactly what they’re buying. Employees want to know their equity grants won’t get diluted by founder reshuffling. Acquirers want a clean cap table, not a formula.
When those situations arise, the benefits of flexibility can get outweighed by the benefits of stability.
Events That Trigger an Equity Freeze
Not every company will face these. But if you do, they’re worth thinking about.
Quick Decision Framework
Ask these questions in order:
- Are you raising outside investment? → Freeze before closing
- Is the business self-sustaining with salaries for all? → Consider freezing
- Are you hiring employees with equity? → Consider freezing for clarity
- Is a co-founder leaving? → Good natural freeze point
- Are contributions still varying significantly? → Keep dynamic equity
The business becomes self-sustaining
This is probably the most common reason to stop using dynamic equity.
Think about why you started using it in the first place. In the early days, nobody’s getting paid a real salary. One founder might be working full-time while another can only do nights and weekends. Someone puts in cash to cover expenses while others contribute sweat equity. Contributions are uneven, so ownership should be too.
But eventually, if things go well, the business starts generating revenue. You can pay yourselves. Everyone’s working their role, pulling a salary, doing the job they’re supposed to do.
At that point, the reasons for dynamic equity start to fade. You’re not taking on the same kind of risk anymore. “I couldn’t contribute as much this month” stops being a valid reason when you’re getting paid to do your job.
Let’s say you’re two years into running a bakery. You’ve been tracking contributions, and the split is 70/30. Now you’re both taking salaries and the business is stable. It might make sense to freeze right there. The 70/30 reflects the risk you each took to build something from nothing. Going forward, you’re both employees of a functioning business.
If you eventually sell, that 70/30 split is how you divide the proceeds. The person who took more risk in the early days gets more of the upside.
Taking outside investment
When a VC or angel writes a check, they need to know what percentage of the company they’re getting. That’s hard to calculate if founder ownership is still in flux.
Most investors will require you to freeze your dynamic split before they close. As Y Combinator notes, investors need certainty about what they’re buying. Some will even help you navigate the process as part of due diligence.
If you’re raising a priced round, plan to freeze beforehand.
Bringing on key employees with equity
Early employees often take below-market salaries in exchange for equity. They’re betting on the company, same as the founders. This is essentially sweat equity—work in exchange for ownership.
But they’re not betting on a moving target. If you tell someone they’re getting 1% of the company, they need to trust that number means something. A dynamic model where founder percentages keep shifting can create uncertainty that makes recruiting harder.
This doesn’t mean you have to freeze. But it’s worth considering whether your hires need more certainty than dynamic equity provides.
What Investors Look for in Your Cap Table
A founder leaving or stepping back
When a co-founder exits, you need to figure out what they walk away with. Dynamic equity gives you a fair answer based on what they actually contributed. (This is exactly the kind of dispute that tanks partnerships when there’s no clear framework.)
After they leave, some teams continue running dynamic equity with the remaining founders. Others use the departure as a natural point to freeze. Either can work depending on your situation.
When You Don’t Need to Freeze
Plenty of companies keep using dynamic equity long-term.
If you’re bootstrapped and plan to stay that way, there’s no investor forcing a freeze. If your founding team is stable and contributions keep varying, the model keeps working.
Some businesses distribute profits based on dynamic ownership percentages rather than ever locking things in. The flexibility that helped in year one can keep helping in year five.
The point of dynamic equity is fairness. If it’s still delivering that, you don’t have to change anything.
How to Freeze Your Equity Split
Freezing isn’t complicated. You’re not actually converting anything or moving equity around. You’re just agreeing that your current percentages become your permanent percentages going forward.
Agree on the final numbers
If you’ve been tracking contributions properly, this is straightforward. Run the numbers one last time. Everyone’s current percentage becomes their permanent percentage.
Make sure all founders agree on the final numbers before moving forward.
Document the agreement
You need a written agreement that all founders sign. This should state:
- The final ownership percentages
- That the dynamic equity period is ending
- How future contributions will be handled (usually salary, not equity adjustments)
- What happens if someone leaves
A lawyer can draft this, or you can use a template and have a lawyer review it.
Set up a cap table
Set up a proper cap table that reflects the agreed percentages. If you’re raising money, your lawyers will handle this as part of the financing docs. If you’re staying bootstrapped, tools like Carta, Pulley, or even a well-maintained spreadsheet work fine.
Consider adding vesting
Here’s where people often push back. “We already earned this equity through our contributions. Why should we vest?”
Because vesting protects everyone.
If a founder leaves six months after freezing, should they keep 100% of their stake? Most investors and co-founders would say no. The standard founder vesting schedule is four years with a one-year cliff, giving everyone continued skin in the game.
You can credit time already spent toward the vesting schedule. If you’ve been working together for two years, maybe founders start 50% vested. The details are negotiable.
What If Founders Disagree on the Equity Split?
This is where things get tricky.
If you’ve been tracking contributions all along, disagreements are rare. The numbers speak for themselves.
But if your tracking was sloppy, or if one founder feels the methodology undervalued their work, you have a problem.
A few options:
Bring in a neutral third party. An advisor, lawyer, or mediator can review the data and help you reach agreement. Sometimes an outside perspective breaks the deadlock.
Negotiate. If the formula says 60/40 but one founder won’t accept less than 50%, maybe you split the difference. Keeping the team together might be worth the compromise.
Part ways. If you truly can’t agree, that’s a sign of deeper problems. Better to figure that out now than after you’ve raised money or hired a team.
The process of freezing tends to surface any lingering resentment about contributions. That’s actually a good thing. Better to deal with it explicitly than let it fester.
Famous Co-Founder Disputes: What Went Wrong
Common Mistakes
Not adding vesting
Founders who skip vesting after freezing often regret it. When someone leaves early with a full stake, the remaining team is stuck with dead equity and limited options. Understanding how vesting works is essential before you freeze.
Vesting isn’t a punishment. It’s insurance.
Frequently Asked Questions
When should founders freeze their dynamic equity split?
The most common triggers are: raising outside investment (investors require fixed ownership), the business becoming self-sustaining (founders are now paid employees), hiring key employees with equity grants, or a co-founder departure.
Can you use dynamic equity forever?
Yes. Bootstrapped businesses with stable founding teams can run dynamic equity indefinitely. Some companies distribute profits based on dynamic percentages for years without ever locking things in.
How long does freezing take?
The conversation and agreement can happen in a day. The legal paperwork (if you’re raising money) typically takes 2-4 weeks as part of financing docs. If you’re staying bootstrapped, you can use a simple founder agreement.
What if co-founders disagree on the final split?
If you’ve been tracking contributions properly, disagreements are rare. When they happen, options include bringing in a neutral third party (advisor or mediator), negotiating a compromise, or in worst cases, parting ways before the problem gets bigger.
The Bottom Line
Dynamic equity solves the fairness problem. It makes sure ownership reflects actual contributions during the uncertain early days when everyone’s taking risk without getting paid fairly for it.
Once the business is self-sustaining and everyone’s earning a salary, that risk-taking phase is over. Freezing your split at that point locks in what you earned during the hard part.
Some companies will use dynamic equity forever. Others will reach a point where they need more certainty and structure. Neither path is wrong.
