answer

  1. Who is the only person who can answer?
  2. Business risk, not daily workflow
  3. Money in, money out, months left
  4. Funding stage, revenue path, moat, key people
  5. One opener: what keeps you up at night

basics

~20 s

Save the questions only an owner of the business can answer: funding stage and months of runway, how the company will make money, what stops a competitor copying it, and which people the business depends on.

solid answer

~40 s

A conversation with a founder is diligence on the business, so spend it on what nobody else in the loop can answer. That means the funding stage and how many months of runway the last raise bought, who pays today and who is expected to pay next, what makes the product hard to copy, and where key-person risk sits. One line opens most of it: 'What keeps you up at night about this business?' — founders usually answer honestly, and their answer tells you what they believe the real risk is. Leave deploy cadence, on-call load and code-review habits for the engineers you meet. Asking a founder about those spends the only slot in which the business itself is on the table.

go deeper

for a junior

Walk in with four things you want from an owner: funding stage and runway, who pays, why competitors cannot copy it, and who the business leans on. Having any of them ready already puts you ahead of most first-time candidates.

for a middle

Be able to say why each item is on your list and who else in the loop could have answered it. Route process questions to engineers so the scarce founder slot is spent on things with no other source.

for a senior

Follow the thread the founder opens rather than reading a list. One honest answer usually touches revenue, defensibility and fragility at once, and the useful work is noticing which of your items just got answered sideways.

for a principal

Own the judgment about how hard to push. You are weighing the information you need against the relationship you are starting, and deciding in the moment which unanswered item matters enough to spend goodwill on.

## Why this conversation is different In a startup loop you usually get one slot with a founder or a senior executive. The engineers you meet own the work; the founder owns the bet. Joining an early-stage company is closer to an investment than a job change — a share of your compensation and several years of your career ride on whether the company still exists and is growing when you get there. That makes the founder slot your **diligence window on the business**, and the questions that belong in it are the ones only an owner can answer. ## The diligence checklist Carry four items and know why each one is on the list: | Item | What you are testing | Who else could answer it | |---|---|---| | Funding stage and runway | How long the current plan is funded for, and what has to be true to raise again | Nobody in the loop, reliably | | Path to revenue | Who pays today, what they pay for, who is expected to pay next | Sometimes a sales leader; usually the founder | | Moat | Why a better-funded competitor cannot copy this in a quarter | The founder | | Key-person risk | Which handful of people the product or the customer relationships depend on | Partly engineers; the founder sees the whole shape | Everything outside those four rows has a better owner. How a change reaches production, what on-call feels like, how review works — those belong to the engineers you meet, and they will give you a truer answer than a founder can. ## A worked example Imagine an early-stage company selling demand-forecasting models to operations teams. Across the table is a co-founder who still writes code. You open with 'What keeps you up at night about this business?' The answer: the models work, but every new customer needs bespoke data plumbing before the first forecast is useful, so onboarding drags. That one answer moves three checklist rows at once. Revenue path: the sales cycle is longer than the pitch implies. Moat: the defensible asset may be the integration work rather than the modelling, which is a very different company to join. Key-person risk: someone is doing that plumbing by hand, and you should ask who. Follow the thread the founder opens rather than marching down your list — the checklist is there so you notice which rows got answered, not so you read it aloud. ## Equity context, kept to shape The founder slot is also a reasonable place to understand what an equity offer *means* in context — roughly what fraction of the company a grant represents, and how founders expect later financing rounds to affect early employees. Keep it to shape rather than terms. Plan mechanics differ from company to company, and the tax and legal treatment of equity varies by country and by personal circumstance, so treat anything said in an interview as background and get independent advice on your own documents before you rely on it. Detailed negotiation of the grant belongs with whoever owns the offer, not here. ## How founders read these questions Direct business questions usually read as seriousness — a candidate who asks about runway is a candidate imagining themselves there in two years. Two caveats. First, tone: this is a conversation, not a cross-examination, so ask, listen, and follow up on what they actually said. Second, calibration: founders differ widely in what they will share, and some are constrained by agreements with their investors, so a partial answer is not automatically a bad sign. The common failure is the opposite of over-asking. Candidates enjoy the founder chat, talk about mission and culture for the whole slot, and walk out without knowing whether the company is funded for the coming year. That is the one mistake this leaf exists to prevent.

  • Two engineers have already walked you through the roadmap — what do you ask the founder about it instead?
    Ask what the roadmap is funded to deliver and what would cause it to change: which item on it is the company's next commercial milestone, and what gets cut first if the next raise slips. Engineers can tell you what is planned; only an owner can tell you which parts are load-bearing for the business.
  • How do you raise key-person risk without implying you think the founder is about to leave?
    Frame it as onboarding, not as doubt: ask which parts of the system or which customer relationships sit with one person today, and what the plan is to spread them. That reads as someone sizing up where they could help, and it surfaces the same fragility a blunter question would.
  • The founder turns it around and asks what you most want to know — what do you lead with?
    Lead with runway against the next milestone, because it frames everything else: how much time the plan has and what has to be true to extend it. Say why you are asking — you are deciding where to spend the next few years — and the question lands as diligence rather than suspicion.

saying these in an interview costs you the question

  • Treating the founder slot as a friendly culture chat only
  • Leaving without knowing how many months of runway remain
  • Asking a founder about deploy cadence or code-review process
  • Asking only about perks, office norms and remote policy
  • Repeating a question three earlier interviewers already answered
  • Cross-examining the founder instead of following their answer
