Only if the money buys a change in the business that debt and cash flow cannot fund, and only after you have modeled what you keep at the exit you actually expect. At 40%, each round costs more than its headline: a 20% round usually becomes 25% once the option pool is refreshed, which takes you to 30%, and a second round like it leaves about 22% standing behind a preference stack that is paid first. So split what you need into repeatable spend, which cash flow or non-dilutive debt should fund, and one-time change, such as a second vertical, a platform rebuild or an acquisition, which is worth dilution. Size any equity to that change alone. Next step: build the exit waterfall at three realistic values before the first investor meeting.
Equity is for the thing that changes the company; debt and cash flow are for more of what already works. At 40%, raise equity once, sized to a named change, or not at all.

Founders track the headline percentage and miss where the rest of the dilution goes. The option pool refresh comes out of existing holders, liquidation preference sits in front of the common at exit, and participating preferred or a ratchet can move more money away from you than the round itself. None of this is hidden, but it bites four years after the term sheet, which is why the meaningful exit plan starts with a waterfall of your own proceeds through the preference stack.
The fix is to stop letting round size set the requirement. A cash flow forecast and a real budget produce the actual gap, which is usually smaller than the round you were offered. The sales efficiency ratio tells you whether the growth spend is repeatable enough to borrow against. What is left after that is the one change that needs equity, and at 40% it deserves a partner and terms you have read against control, not just price. A board you would want in a bad quarter is part of what you are buying.
A founder owns 40% of a company at $4M in annual revenue and is offered $6M for 20%, with a pool refresh. The forecast shows the real need is $3.5M: $2M to hire and ramp sales on a channel that already pays back, and $1.5M to build a module for an adjacent segment. She funds the sales hires with a term loan against ARR and raises $1.5M–$2M of equity for the module only, selling closer to 10% than 25%. At a $60M exit that difference is worth several million dollars to her before preferences. All figures are invented for illustration.
If the company is growing fast enough that a larger outcome is genuinely plausible and the founder wants to run it that way, venture-style dilution can be rational. And a founder with a co-founder or employee pool already carrying most of the dilution may have a different threshold than 40% suggests.
From the Golden Section mistakes list, each paired with the play that prevents it.
Founders at 40% often sell equity for spend that a lender would fund at a known cost.
At this ownership level the partner matters as much as the price, and vetting runs in both directions.
The terms that erode a 40% stake live in the documents, and hasty legal review is how they get missed.
In the order we would run them. Each is on its own page, most with a free Excel template.
Starts with your own proceeds through the preference stack, which is the only number that decides whether the round is worth it.
Produces the real capital gap, which is usually smaller than the round on offer.
Separates repeatable spend from one-time change inside a realistic plan.
Shows whether growth spend is proven enough to borrow against instead of selling equity.
Sets out what a useful board looks like, which is part of what the next equity round buys.
Growth Capital Without Heavy Dilution The guide walks through sizing the real requirement and where dilution actually goes.
There is no universal number; what matters is what you hold at exit after preferences. Founders on The Balanced Path, raising one or two rounds, typically own 40–60% at exit, against 15–25% for founders through multiple venture rounds. Work backward from the exit you want rather than forward from the round.
No. Many companies stop diluting at this point by funding growth from cash flow and non-dilutive debt, which is often the most valuable decision a founder at 40% makes.
Liquidation preference above 1x, participating preferred, ratchets, drag-along rights and protective provisions that amount to control. Price affects one number at exit; terms affect every decision until then.
We write roughly $5M of minority equity sized to a specific change, and lend $500K to $5M against ARR for spend that already works, so a founder at 40% can take one without being pushed into the other.
