Capital, cash and fundraising · Answered by Golden Section from more than 400 B2B software companies observed
Our working guide for vertical B2B software is $1M to $2M of equity to reach $10M in annual revenue, tilted toward the top of that range, or a somewhat larger round, when the goal is to get there faster. Customers and debt fund the rest of the path. Our published reference point is that the average SaaS company takes about $8M of equity to reach $5M in ARR, while our portfolio averages about $1M. Reaching $15M on under $2M is achievable but very hard, though AI is making it more realistic and one of our companies is doing it today. Your own number still comes from a monthly forecast built on measured sales efficiency and gross retention: find the trough, add a six-month operating reserve, and fund repeatable spend with cash flow or debt before equity.
Plan on $1M to $2M of equity to reach $10M, and size each raise to the trough of a monthly cash flow forecast plus a six-month operating reserve, never to a round size. Use equity only for the part that buys speed or a structural change a lender will not fund.

Capital to reach a revenue milestone is arithmetic with three inputs. Sales efficiency sets what each dollar of new ARR costs to book. Gross retention sets how much of that spending replaces revenue that left rather than adding to it. Gross margin sets how much of the existing base pays for the next turn. Change any one and the answer moves by millions, which is why a benchmark from someone else's company is a weak substitute for your own cash flow forecast.
The cost of getting it wrong compounds. A founder who raises to a round size rather than a requirement sells equity for working capital, then finds the company needs a real structural change later and must fund it from a smaller stake. The growth capital guide sets out the three parts of the real number: the gap to self-funding, the cost of the step, and the reserve.
Where the capital comes from matters as much as how much. The SaaS Capital Flywheel shows how reinvesting a larger share of ARR, funded by debt against proven channels, compounds faster without selling ownership. Equity is best kept for what a lender will not fund.
A company at $5M ARR, built on $400K of equity, wants to reach $10M in three years. It books new ARR at $0.90 of sales and marketing per dollar and retains 90% of revenue gross. Over three years it must add $5M of net new ARR and replace roughly $2.2M of churn on an average base near $7.5M, so it needs about $7.2M of gross new ARR at a sales and marketing cost near $6.5M. Gross profit from the growing base covers most of that, and its forecast shows a trough of $1.4M in the first year. It raises $1.5M of equity for the trough and holds the six-month reserve as an undrawn credit facility. Total equity lands near $1.9M, inside our range and far short of the $10M round it was offered. The figures are invented for the arithmetic.
Most vertical companies reach $1M on founder effort, customer cash and small angel checks. Our equity does not enter below $1M in annual revenue and our lending starts at $1M ARR with 90%+ net revenue retention, a useful marker for when outside capital becomes cheaper to get.
The Balanced Path reference point applies here: about $8M of equity for the average company against about $1M in our portfolio. The gap has narrowed somewhat as our portfolio has scaled, but it still holds, and it comes from habits kept from day one rather than from one decision.
Our target is $1M to $2M of total equity to get here, more if speed is worth the dilution. By this size borrowing capacity has usually grown with ARR, and refinancing at better terms is the cheapest capital available. Further equity should be sized to a specific change such as a second vertical or an acquisition.
Companies with long implementation cycles or heavy regulated product work can need more capital before revenue arrives, and an honest forecast will show it. A company with gross retention below 90% has no reliable capital number until retention is fixed.
From the Golden Section mistakes list, each paired with the play that prevents it.
Capital plans that bank on growth accelerating later understate how much is needed, then overcorrect with an oversized raise.
Growth consumes cash faster than a linear plan assumes, so the trough arrives earlier and deeper than expected.
A requirement sized without a reserve is how a company that was on plan still runs out of cash.
Raising to scale an inefficient channel increases the capital needed rather than the ARR produced.

Measures the cost of new ARR, the largest input to the capital number.
Reduces the churn that silently raises the capital required.
Turns the inputs into a monthly trough and a defensible requirement.
Makes the plan behind the forecast realistic and owned.
Gives lenders and investors the evidence behind the forecast.
Growth Capital Without Heavy Dilution It sets out how to find the real capital requirement and which instrument should fill each part of it.
Divide current ARR by total equity raised. On the Balanced Path figures at $5M ARR, the average company sits near 0.6x and our portfolio near 5x. There is no universal target, but a ratio below 1x means each equity dollar has produced less than a dollar of recurring revenue, and the next raise will be priced accordingly.
Whatever your forecast says after measured sales efficiency, retention and a six-month reserve, which for a capital-efficient vertical company is often far below the $8M of equity the average company uses. Our portfolio averages about $1M of equity to get there, with the rest coming from customers and debt.
Yes, but it is very hard, and our cash flow forecast play asks for proof of top-10% performance before a model that lean is trusted. AI is lowering the cost of building and selling software, which makes the path more realistic, and one of our companies is on it today. Plan on it only if your measured sales efficiency and retention already support it.
Our equity is sized to a specific change, about $5M for a minority position, and our lending funds repeatable spend at $500K to $5M, so the split between them follows from your forecast. If the forecast says the company can fund itself, that is the better answer.
