Cash is expensive and the bill stops. Equity feels free and the bill never stops. That is the whole trade, and founders get it wrong in the same direction almost every time, because the invoice for equity does not arrive for four years and the invoice for cash arrives on the thirtieth.
Put a number on it. Suppose you give away five percent to get a product built. Suppose the company eventually sells for fifty million. Your dilution along the way means that stake is no longer five percent, but even at half that it cost you well over a million dollars for work that had a cash price somewhere around two hundred thousand. Nobody does this arithmetic at pre-seed, because fifty million is a fantasy and the two hundred thousand is real money you do not have. That gap is the whole problem.
What each one actually costs
Cash
Bounded, known, and finished when it is finished. You pay, the work lands, the relationship ends unless you choose to renew it. The invoice is the smaller cost. The larger one is that you are spending your scarcest resource on a guess. Every month of runway spent building is a month you are not spending finding out whether anyone wants the thing.
Equity
Nothing leaves the bank account, which is why it is tempting. What you have done instead is add a permanent name to the cap table. That name appears in every diligence pack, every future financing, and every conversation about who owns what. Some investors will ask why a build shop holds eight percent of your company, and “we had no money” is a true answer that still costs you something in the room.
The asymmetry is worth stating plainly. Cash paid for a finished deliverable stops. Equity paid for a finished deliverable keeps paying, every year, whether or not anyone from that firm has thought about your company since the launch.
What changes when your builder holds equity
The upside is real and worth taking seriously. Someone with a stake cares what happens after launch. They will argue with your roadmap instead of quietly building whatever you asked for. They will pick up the phone on a Sunday. A firm paid in cash has a natural incentive to deliver the scope and move on. A firm paid in equity has an incentive to make the product work, and those are genuinely different jobs.
The downside gets discussed less. An equity holder has opinions about direction and now has standing to press them, which is fine when you agree and tiring when you do not. More importantly, a studio holding positions in twenty companies is running a portfolio. Your project competes for their best people against the one in that portfolio that is currently working.
A cash client can stop paying tomorrow. An equity partner has already been paid.
None of that argues against equity partnerships. It argues for asking how many positions they hold and how they decide where the good people go, before you sign anything.
Pre-seed and post-revenue are different questions
Before revenue, equity is the only currency you really have. It is also the moment you know least about what is worth building. Handing over a large stake to build version one is a bet that version one is correct, and version one is usually not correct. If you are going to trade equity at this stage, trade it for the smallest piece of work that answers a real question, and keep the option to buy the rest with cash later.
After revenue the answer flips. Money coming in makes cash cheaper and makes equity more expensive, because your shares now have a price somebody could defend. A useful line: if you can fund the build from revenue or from a round without pushing runway below nine months, pay cash. It will feel like the expensive option and it is the cheap one.
The structures in between
The choice is rarely all of one or all of the other, and the middle is where most sensible arrangements live.
- Reduced rate plus a small equity slice. Works when the discount is genuine, somewhere in the thirty to fifty percent range, and the equity is small and vests against delivered milestones rather than on signature.
- Milestone payments. Cash, but released per shipped increment. Aligns incentives without touching the cap table. This should be most founders' default.
- Deferred cash. They work now and invoice at the next financing, often with a premium for the risk. Ask for a cap on that premium in writing.
- Advisory grant. A quarter to one percent over two years, for judgment rather than labour. Cheap, useful, and frequently confused with paying for a build. It is not one.
- Warrants or a side letter on your next round. Instead of shares now, the right to buy at today's price later. Costs you nothing today and pays them properly if the company works.
Questions to answer before you give equity to a non-founder
Every one of these has ended a deal that would otherwise have been signed, which is the point of asking them early.
- What happens if they stop working in month four? If the equity does not vest against something you can observe, you have written a gift.
- Is this the last time I will need them, or the first? Equity bought at project prices is expensive when the project turns into a five-year relationship.
- Would I hire this firm at full rate if I had the money? If the answer is no, you are not saving cash. You are buying something you already rejected.
- How many other companies do they hold equity in, and how many of those are getting real attention this quarter?
- Does my existing investor or my next one need to approve this, and have I actually asked?
- Would I be comfortable explaining this arrangement out loud in a diligence meeting? If you would rather it did not come up, do not sign it.
Where we land on it
Equity for build makes sense in a narrow set of situations. It works when the firm is genuinely taking on work they would otherwise decline, and when both sides expect the relationship to run for years. It works when a founder has no cash, has done the diligence, and has a specific reason to believe in this specific team rather than a general belief that alignment is good.
Outside those cases it is an expensive way to buy something that has a price tag on it. The expense is invisible for four years, which is exactly why so many founders find out about it at the worst possible moment.
