We had four hundred thousand left when revenue covered burn. We didn’t celebrate. We left it in the account. Eighteen months later that four hundred thousand was the reason we said no to a bad term sheet.
This is the part of small-company finance nobody writes about because it’s boring: the cash you raised, didn’t spend, and held. It looks like waste on a hiring deck. It is, in fact, the cheapest insurance product available to a founder, and the one you can never buy back at the price you sold it for.
What unspent runway buys you
Three options, in roughly the order they save you:
- Saying no. A bad acquisition offer, a hostile term sheet, a partnership that wants to put you on a clock — all of these are easier to decline when the runway gives you another twelve months. The discount investors give for “we have to close this” is large and well-documented.
- Taking a bad month. Every small business has a quarter where the wheels come partly off. Churn spikes, a key hire leaves, a major customer renegotiates. With twelve months of runway, you fix it. With three, you panic.
- Doing the right thing slowly. The right rewrite, the right cofounder split renegotiation, the right pricing change — all of these get worse when done under cash pressure. Unspent runway lets you take the time the decision deserves.
What it costs
It feels wasteful. Engineers see headcount budget that could have hired the second backend engineer. Investors see a runway chart with a flat line where they wanted hockey-stick growth. Both are wrong, but you’ll hear both regularly.
The real cost is a real one: the money sitting in the account isn’t earning anything close to what you’d get from deploying it well. There’s a cost of capital, and you should know it. Put it in T-bills. Don’t pretend it isn’t there.
What I’d actually do
Run the company so revenue covers burn at the smallest size that lets you do the work well. Raise less. Spend less. Keep the difference in something boring. When the bad month comes — and it will — you’ll have written yourself a cheque that nobody else was willing to write you.
