I have this conversation more times than I can remember. A friend of mine who I've known for a few years now recently gave me a call to discuss equity in a new business. The business that he's going into is giving him the option to either put his own cash in for a stake or work for some sweat equity. He wanted to workshop it. Which would be better?
Before anything else, the caveat I gave him on the call is the same one I'll give to you. I am one guy who has done this a number of times, and this is a friend talking to a friend about what he has seen. It is not legal advice and it is not financial advice.
Let's start with where equity sits. It is at the bottom of the cap (capitalization) table and underneath every layer of debt, which makes it the most at-risk capital in the business. Everybody else gets paid before you do. So buying in with cash means putting real money into the riskiest position in the company today, and getting nothing back until every other claim has been settled.
The argument people make against sweat equity is that the company would have paid you the cash anyway, so $100,000 in salary plus $10,000 in equity is really just $110,000 in salary. That trade is rarely on the table. Sweat equity usually arrives on top of what you were going to be paid, because it is not cash going out of the door and it lines everybody up behind the same result. The people handing it out like it for that reason too.
Which makes it close to free upside. If the business works you have something, and if it does not, you were paid for your time either way.
What vesting is, and why it is there
Sweat equity does not land in your account on your first day. You earn it across a period of time, a slice at a time, and that is called vesting.
It exists because equity handed over on day one is equity gone. If somebody joins, takes 10% and leaves four months later, the company has paid a permanent price for a temporary contribution, and everybody still there has been diluted for nothing. Vesting ties the reward to the time actually served. It protects the business from the person who leaves early. If you're in the cap stack, that means it's protecting you.
Expect something around four years with a one-year cliff.
The cliff is the part worth understanding, because it works as a step rather than a slope. Nothing vests at all until you have been there twelve months. Reach that point and the whole first year arrives in one piece, and from then on the rest usually accrues month by month. Leave at eleven months and you walk away with none of it, however good the year was.
That is kind of standard rather than a hard and fast rule, so ask instead of assuming. Carta (the platform a large share of US startups run their cap tables on) looked at grants made between 2019 and 2024 and found only about 70% of employee grants carried a cliff at all.
Vesting cuts both ways in any case. It ties you in, and it also buys you two years inside the business to work out whether you want the other two.
If you are putting cash in, make it buy something
My rule for myself is that cash goes in only if it buys either a controlling say in how the business is run, or preference on the way out.
Preference sounds like a formality and it is not. It's really important.
Say you put $10,000 in for 10%, and the company later sells for $110,000. With ordinary common stock you take 10% of the sale, so $11,000, and you made 10% on your money.
A liquidation preference moves you to the front of the queue, so you get your $10,000 back before the common holders see anything. There are two versions of preference equity, and one functions a little bit like a safety net, while the other functions more like a multiplier.
With a non-participating preference, at a sale you can either take the $10,000 back, or give that up, convert to common and take 10% of the whole $110,000, which is $11,000. You take whichever is larger. On a disappointing sale the preference protects your money, and on a good one you convert.
Participating, which people call the double dip, gives you both. Your $10,000 back first, then 10% of the remaining $100,000 on top, so $20,000. You can think of it somewhat like a loan with the upside as the interest.
Almost every professional investor asks for a preference of some kind, and plenty of first-time founders have given this up without really understanding the implications. Most of what actually gets agreed is the milder version. Depending on whose deal data you read, somewhere between 93% and 98% of venture rounds carry a preference of one times the money, and between 86% and 97% of those are non-participating. The higher numbers in both ranges come from the law firms acting on the most founder-friendly deals.
So if professional money is taking a preference and you are being offered plain common stock for your cash, you are standing behind them in the queue and paying for the privilege.
What the equity turns out to be worth
Carta looked at in-the-money options that expired in 2022 and found that about 46% of them expired without being exercised. That is people walking away from money that was actually there, mostly because exercising costs cash up front and triggers a tax bill before there is anything to sell.
And a preference stack can leave common stock worth very little even when the sale looks respectable from outside. When BlackBerry bought Good Technology in 2015 for around $425 million, common stock was priced at $0.44, having been valued at $4.32 a year or so earlier while the company was talking about going public. The preferred holders were paid. Employees who had exercised early had tax bills larger than their shares were worth.
However, as mentioned earlier, if it comes on top of your salary, take the sweat equity, because the downside is time you were going to be putting in anyway. I would just think of the whole thing as a long-term lottery ticket rather than part of your pay package (which, of course, you have an impact on).
