The startup cap table is simple until it isn't. Founders see it early — a spreadsheet with two names and a few percentages — and don't give it much thought until three rounds in, when the person who wrote the first check has information rights, pro-rata, and a provision that complicates the latest term sheet.
By then, the decisions that matter have already been made.
What a startup cap table actually tracks
A startup cap table — short for capitalization table — is the master record of who owns what in your company. It tracks shares, options, warrants, and convertible instruments. It shows fully diluted ownership: what everyone owns after every outstanding option and convertible note converts into shares.
The cap table isn't just a spreadsheet. It's a map of power. It tells you who can block a board decision, who has liquidation preferences in a sale, who gets diluted when you raise the next round, and what everyone walks away with in an exit.
The founders who understand their cap table early make better decisions about every dollar they raise and every equity grant they issue. The ones who don't tend to hit surprises at the exact moments when surprises are most damaging.
The three instruments that make cap tables messy
Most startup cap tables start clean: founders split the equity, issue some options for early hires, and that's it. Complexity comes from instruments that convert into equity at a later date.
SAFEs (Simple Agreements for Future Equity) and convertible notes are the most common. They let early investors put money in without agreeing on a valuation. The investor gets the right to convert into shares at the next priced round, usually at a discount to whatever price the new investors pay.
The catch: every SAFE and note that converts creates dilution for the founders — and the discount and valuation caps built into those instruments determine how much.
An uncapped SAFE can look fine until you raise your series A at a high valuation and realize the early investors converted at a fraction of that price. The math works against you in ways that weren't visible when you signed.
Options are the third source of complexity. Your employee option pool — typically 10–15% of fully diluted shares — gets created, often by diluting the founders, before a priced round closes. That's standard, but founders who don't model it in advance consistently underestimate how much it affects their ownership coming out of the first institutional raise.
Liquidation preferences: what they are and why they matter more than your percentage
Owning 30% of a company sounds meaningful. Whether it is depends entirely on what sits above you in the liquidation stack.
Liquidation preferences determine who gets paid first when a company is sold or wound down. A 1x non-participating preferred means an investor gets their money back first, then participates in the upside as a common shareholder. A 2x participating preferred means they get twice their money back first, then participate alongside everyone else.
In a strong exit — a high-value acquisition or IPO — liquidation preferences matter less because everyone makes money. In a moderate outcome — a company sold for less than its post-money valuation — the preferred stack can mean founders and employees walk away with significantly less than their ownership percentage suggests.
How dilution works in practice
Every time you issue new shares — through a funding round, an option grant, or a converting instrument — existing shareholders own a smaller percentage of a larger pie. That's dilution.
The goal isn't to minimize dilution. It's to ensure the pie grows fast enough that your smaller percentage is worth more in absolute terms than your larger percentage was before. That math works when you're raising at increasing valuations from investors who add value beyond the check.
Where founders get into trouble is issuing equity cheaply or carelessly in the early days — to co-founders who leave, to advisors who don't contribute, to early employees on terms that don't vest properly — and then carrying that baggage into a fundraise where it raises questions.
A cap table that shows 25% of the company sitting with someone who hasn't been involved for two years is a problem. Eight SAFE holders from a friends-and-family round, no lead, and no institutional investor is a yellow flag to most VCs.
What a clean startup cap table looks like
Clean means simple, defensible, and predictable. Founders own the majority, with standard 4-year vesting and a 1-year cliff. Any co-founder departures have been addressed — through buybacks, cliff provisions, or documented agreements. The option pool is reserved but not over-issued. If there are SAFEs, they carry a valuation cap, no MFN provisions that create future obligations, and there are a manageable number of them.
Every instrument on the cap table should be explainable in one sentence. If it takes a paragraph to explain why a particular holder has their specific terms, that's drift that needs to be cleaned up before the next raise.

What Alder looks for
When we look at a startup cap table, we're asking a few things. Does it reflect decisions made intentionally, or does it show equity was issued casually? Are the founders still properly incentivized — meaning they own enough to care, with enough upside to make the years of effort make sense? Do any instruments create future landmines that a lead investor would find and object to?
A cap table that answers those questions cleanly is a fundraising asset. One that doesn't is a problem to solve before you start the process.
