The Questions VCs Ask Software Founders That Most Aren't Ready For

Investor meetings rarely go off-script. After reviewing hundreds of decks and sitting across from early-stage founders, the same questions surface — and the same hesitations follow.

Here are the ones that matter most.

"What's your net revenue retention?"

Most seed-stage founders quote top-line growth. The ones who stand out know their NRR cold. Anything above 110% tells an investor that your existing customers are expanding faster than you're churning - which fundamentally changes the risk profile of the business. Below 90%, and you're running to stand still.

"How long does it take a new customer to hit full value?"

Time-to-value is a proxy for product complexity and sales efficiency. If onboarding takes three months and your average contract is $12K ARR, the unit economics look very different than if activation happens in week one.

"What does your CAC look like by channel?"

Blended CAC hides problems. Investors want to know where your best customers come from and whether that channel scales. A founder who can say "our inbound CAC is $800 versus $4,200 for outbound, and inbound is growing 40% quarter-on-quarter" is having a different conversation than one who quotes a single number.

"What breaks at 10x?"

This is a founder judgment question as much as an operational one. Investors are trying to understand whether you've thought past the current raise. The ones who have a concrete answer — infrastructure, support ratio, sales motion — signal that they're building a company, not just closing a round.

Being unprepared for these questions doesn't just lose points. It raises doubts that are hard to walk back.
