The cap table conversation I have with growth-stage founders and CEOs follows a similar pattern. The company has real revenue, a real team, and a raise or acquisition on the horizon.
Then the diligence process starts, and something surfaces that nobody planned for:
- A co-founder who left years ago and still owns equity
- An option pool sized for a company half the current size
- A SAFE that was never modeled against the existing cap structure
All of these have a cost.
This article is a practical breakdown of the five cap table mistakes we see most often inside companies at the $1M to $50M stage, and how to get ahead of them before the deal pressure starts.
TLDR
- Dead equity from founders and early advisors without vesting schedules reduces your valuation at exit.
- An option pool built for an earlier version of your company creates asymmetric dilution as you grow.
- Unmodeled convertible instruments mean your real, fully diluted ownership is probably not what you think.
- A spreadsheet isn't a cap table management system.
- Informal option grants and stale 409A valuations create legal and tax exposure that surface at the worst possible moment.
Mistake 1: Dead Equity From the Early Days
When a co-founder leaves or an early advisor goes quiet, the equity they were promised doesn't disappear unless the right legal structure was in place from the start. A proper vesting schedule with a cliff means unvested shares return to the company. Without one, that person owns their full allocation regardless of whether they contributed for six months or six years.
I see this more often than founders expect. A company can reach meaningful scale while still carrying equity owned by former founders, employees, or advisors who haven't been involved in years.
During diligence, buyers and investors will evaluate whether the cap table reflects the people creating value today. In some cases, that leads to buyouts, negotiated restructurings, or tougher deal discussions. None of those outcomes are free.
If your early equity grants weren't structured with vesting, it's worth reviewing what's sitting on the cap table now, who holds it, and whether a buyout or renegotiation is possible before you go to market.
Mistake 2: An underplanned option pool
The option pool you created at your seed round was designed for the team you had then, not necessarily the team you have now.
If you've scaled from 10 employees to 40, it's worth asking whether the pool still supports your hiring plans. In many companies, a significant portion of the pool has already been allocated, leaving less flexibility for future hires.
The mechanics matter. When an option pool needs to be expanded, the way it's structured determines who bears the dilution: founders, existing investors, new investors, or some combination of the three.
The executives you're trying to recruit are sophisticated enough to ask how much equity is actually available and what future grants may require.
Before your next financing, make sure your option pool reflects both your growth plans and the ownership implications of expanding it.
Mistake 3: A Dilution Surprise Waiting to Happen
Growth-stage founders typically have a number in their head for their ownership percentage. That number is often incorrect, and the gap comes from instruments that were never modeled together.
- A SAFE from three years ago
- A convertible note from a strategic partner
- Warrant coverage attached to a debt facility
Each of these has conversion mechanics that stack. When they all convert, the dilution is real and often material. Founders who discover mid-negotiation that their fully diluted ownership is significantly lower than expected are at a serious disadvantage. That discovery should happen in a model you control, not in a term sheet from a buyer.
If you haven't modeled your full dilution waterfall recently, across every instrument and every conversion scenario, that's the first thing worth doing. At Cypher, we help leadership build that picture before they go to market; the number is almost always lower than expected.
Mistake 4: A Spreadsheet Where a Platform Should Be
There's a version of this that made sense. You had 10 employees, no institutional capital, and the cap table fit on one tab. At your current headcount and capital complexity, a spreadsheet can be a liability. Here’s why:
- It doesn't update automatically when someone leaves and forfeits unvested options.
- It doesn't produce the cap table export a growth equity firm will ask for on day one of diligence.
- It doesn't track all instruments in a single view or flag when something is out of date.
The platforms built for this, Carta, Pulley, and Qapita among them, offer migration support and aren't expensive relative to what a disorganized cap table costs you during a raise.
Mistake 5: Options Issued Without the Right Documentation
Two specific gaps come up constantly at this stage.
The first is options issued against a stale 409A valuation, if you are based in the United States. At your revenue level, the IRS expects your 409A to reflect a company of real value. Issuing options against a valuation that's 18 months old, particularly after a financing round or a significant revenue milestone, creates tax exposure for every employee who received those grants. It also creates personal liability for the board members who approved them.
The second is options that were promised in offer letters but never formally approved at a board meeting. This happens often in the early years when the company's moving fast and formal governance feels like overhead, but those informal grants are a diligence problem. They either need to be formalized retroactively, which requires board action and legal work, or disclosed as a liability, which affects the deal.
Both issues are solvable but much easier to solve now than mid-process.
What Getting This Right Looks Like
There's no single intervention that fixes a messy cap table. It's a sequence of work that needs to happen before your next financing or exit process, not during it.
- Move to a dedicated equity platform this quarter. Carta, Pulley, and Qapita all offer migration support. The cost is trivial relative to the legal fees involved in reconstructing a disorganized cap table under deal pressure.
- Commission a full cap table audit. Your corporate counsel or a specialist firm should reconcile every instrument against your legal documents. This typically takes two to four weeks and surfaces everything that needs fixing.
- Get a current 409A valuation. If your last valuation is more than 12 months old, or if you've raised since then, get a new one before you issue another option.
- Model your full dilution waterfall. Run scenarios for your likely next round, a strategic acquisition at various valuations, and an IPO path if relevant. Know your number before a buyer tells you what it is.
- Appoint a single cap table owner. At your stage this is typically your CFO or Head of Finance. One person, one platform, one source of truth.
This really isn't a someday project. Every month of delay is another month of complexity accumulating before your next raise or exit process.

Frequently Asked Questions
When should I move off a spreadsheet and onto a cap table platform?
The honest answer is that you probably should have already. If you have more than 20 employees, any convertible instruments, or a raise in the next 12 months, a spreadsheet isn't the right tool. The migration process is straightforward and the platforms offer support. The cost of waiting is higher than the cost of moving.
Do I need a new 409A every year?
At a minimum, yes. You also need a new one after any financing event and after any material change in the business, such as a significant revenue milestone or a new product line. The IRS expects the exercise price of your options to reflect fair market value at the time of grant. An 18-month-old 409A at a company that's since raised or grown materially doesn't meet that standard.
What is dead equity and why does it matter?
Dead equity is ownership held by people who are no longer contributing to the company. Co-founders who left early, advisors who went quiet, early employees who left before proper vesting structures were in place. It matters because it dilutes everyone else's ownership without providing any operational value, and because buyers and investors will price it when they evaluate the company.
How do I know if my option pool is the right size?
It depends on your hiring plan and your expected financing timeline. A pool that covers your next 12 to 18 months of hiring at the grants you need to offer is a reasonable target. The more important question is whether the pool was structured correctly, pre-money versus post-money, and whether it's been updated to reflect the company you are today rather than the company you were when you raised your seed round.
What happens if informal equity grants are discovered during diligence?
They need to be resolved before closing. That means either formalizing them with board approval and proper documentation, negotiating a buyout with the person who holds the informal promise, or formally documenting that no obligation exists with legal counsel involved. Diligence teams will ask for every offer letter, every advisor communication, and every equity-related document going back to incorporation. The time to clean this up is before that process starts.
