When should you hire instead of extending the runway?

When the product has already found its market and what limits your growth is how much you can execute, not how much demand you have. The Startup Genome study called it premature scaling (spending on growth, like hiring or marketing, before that fit) and named it the number-one cause of death for high-growth startups. Hiring makes sense once the fit is there.

Which metric do you look at first?

Retention. If people don't come back, hiring speeds up spending without moving what gates the next round. Extending the runway buys time to fix retention before you scale.

How many months of cash should you keep?

A widely cited rule says raise 18 to 24 months and start fundraising with about 18 left, because closing a round takes around 6 months and you need another 12 to 18 of real work to reach the milestones the next round cares about. Recent SVB data shows many now target 24 to 30 months. It's a guide, not a law.

Hire now or extend your runway

In short

If the product hasn't found its market yet, extending the runway is usually the prudent move. The Startup Genome study put a name to what kills most startups (premature scaling: spending on growth too early) and marked it as the number-one cause of death; it estimated that roughly 70% scaled too soon¹. Hiring pays off once the fit is there and what holds you back is how much you can execute, not how much demand you have. The compass, almost always, is retention.

It's the decision that can determine whether you reach the next round, and yet it's usually made on instinct: it feels like you should grow, and growing translates into hiring. The numbers are worth a pause. Looking at some 3,200 high-growth tech startups, Startup Genome found that the ones that scaled in an orderly way grew about twenty times faster than the rushed ones, and that none of the rushed ones even reached a hundred thousand users¹. The underlying reason is simple and a little cruel: growing too early burns the cash faster and leaves you less room to realize you were wrong and course-correct².

The question isn't "do I hire?"

The useful question is a different one: what's holding back growth, demand or my capacity to serve it? If it's demand (people don't come back, don't buy), more hands won't fix it; they'll just make the bill run down faster. If it's capacity (you have demand you can't keep up with), then yes, hiring buys real growth. Everything else is noise around that distinction.

Side by side

Criterion	Hire now	Extend the runway
What you gain	Speed	Months of life and room to be wrong
What you give up	Months of cash	Short-term speed
Better when	The product has fit; demand > capacity	No fit yet; retention is shaky
The risk	Burning cash without moving metrics	Going so slow the moment passes
The signal	Retention and conversion above target	Retention below target

On how much cash to hold: a widely cited rule suggests raising 18 to 24 months and going out to fundraise with about 18 left, because closing a round takes roughly half a year and then you need another year to eighteen months of real work to show progress³. Recent SVB data shows many now aim for 24 to 30 months³. Treat it as guidance, not law.

How Verdika lays it out

You give it the problem and what you have on hand: retention, conversion, how much cash is left, the candidate on the table. Verdika looks at each figure, decides how much to trust it, and puts what you gain in speed against what you lose in months of life. What's left is a ranked set of options with their score, their assumptions, their risks, and their level of certainty. A memo to walk into the meeting with, no improvising.

Frequently asked

What if I have demand but retention is shaky?

That's the most deceptive signal: the product attracts but doesn't hold. Hiring to sell more is pouring water into a leaky bucket. Fix the leak first.

Does it change anything if the hire is in product?

It can. If the bottleneck is precisely fixing retention, that person is capacity, not blind spending. The condition is that their impact can be seen within the quarter.

Put numbers on the dilemma, not hunches.

Verdika shows what you gain and what you lose on each path, with its margin of error.
