The Dilution Playbook The valuation is not the deal. Know the cost before you sign.
Founders negotiate hard on the one number they understand and accept the defaults on the rest. This guide shows what raising really costs: the pool, the stack, the terms and the whole path, so you own every share you give up on purpose.
Nothing dishonest happened. They just never modelled it.
There is a conversation the week after a founder closes a first proper round. They look at a cap table someone else built and find they own far less than they believed when they shook hands. Every number was disclosed, agreed and signed. They were told the valuation and assumed the valuation was the deal. It is the headline. The pool, the preference and the stack are the deal.
None of them is "know your numbers".
Every point you give up is gone for good and then multiplied by every future round. You cannot earn it back by working harder. An afternoon of arithmetic beats a quarter of execution.
Reasonable-looking rounds compound into a result you would not have accepted if you had seen it drawn out. Model this round, the next one and the one after.
Created before the money, it is paid for by the existing shareholders alone. Created after, everyone shares it. Same pool, different outcome, and the default favours the investor.
Preference, participation and anti-dilution govern what investors receive at an exit. In a mediocre outcome, the most likely one, they decide whether you get a meaningful sum or nothing.
You may not control your alternatives. You control your clarity. A model you can run in the room lets you say no while saying no is cheap.
People who keep it current answer a diligence request in an afternoon. People who do not spend weeks rebuilding it at the moment their attention is worth the most.
Understand it, whether or not you ever raise.
If you never raise, it shows what you are protecting, in numbers rather than in principle. If you do, it means you are not the person in that conversation the week after.
Five parts, in order.
Six mechanisms that each move real money or leverage, and the honest limit: the model is for comparing options, never for predicting a number.
Whether to raise at all, what you are optimising, how much from the milestone, the option pool, what you have already sold, pre and post-money, and your walk-away.
Four calculations: post-money ownership, the pool on either side of the money, the stack converted together, and the exit waterfall. Plus vesting and anti-dilution.
Negotiate the terms that move the outcome, model every offer before you respond, explain equity honestly, and keep the table diligence-ready.
Before you raise, evaluating a term sheet, and cap table hygiene. Each line is a box you either can or cannot tick.
Nine ways founders lose ownership. All of them are failures of preparation, not of intelligence, and every one is a choice.
Write down what capital would let you do that revenue and evenings cannot. If the line is empty, that is your answer. Raising because it is what people are supposed to do is not a reason.
Model it after the investment, then before. Compare your ownership in both. The difference is what the convention costs you, and a specific number is a conversation you can win.
Minimum ownership, the preference structure you will not go past and the control terms you will not concede. Sign it, date it, give it to someone who will read it back to you.
- You own all of a business you built and want to know exactly what giving up a share would cost.
- You want to be able to model an offer in the room, not take it away and grow attached to closing.
- You are willing to run the exit at a disappointing price, not just a good one.
- You want arithmetic you can check, not a pep talk.
- You want a valuation for your business. The guide is clear that nobody can prove one.
- You want a prediction of your ownership at exit. The model compares options, it does not forecast.
- You want a reason to raise because everyone else does.
- You expect the guide to negotiate for you.
You own all of it right now.
That is not a placeholder you are waiting to trade away. For a great many businesses it is the ending, and a better one than the alternative most people default into. Know what you would hand over, so if you ever do it, you do it on purpose.
