What Questions to Ask a Startup Founder Before Investing

Why Your First Meeting Matters

The first meeting with a founder is your chance to verify what you read in the deck and discover what isn't in the deck. Most investors waste it on easy questions that confirm what they already know.

The best investors use the first meeting to stress-test the founder's conviction, uncover hidden problems, and assess judgment.

Here's the question framework I use.

The Five Categories

Category 1: Problem & Market

"What's the #1 reason customers buy from you today?"

Not what they will buy, what they actually buy. If the answer is different from the pitch, that's a signal.

"If I gave you $10M tomorrow, what's the one thing you'd spend it on?"

Tests priorities. Good founders have a clear answer. Mediocre founders give vague answers about "hiring" and "marketing."

"Who have you lost a customer to in the last 6 months, and why?"

The best founders know exactly why they lost. If they can't answer, they don't understand their market.

"What's the most surprising thing you've learned about this market since you started?"

Tests coachability and market learning. If they say "nothing surprising," they haven't been paying attention.

"If your competitor dropped their price to free, what would you do?"

Tests whether they understand their differentiation. If they can't answer, they don't have real differentiation.

Category 2: Product & Technology

"Show me the last feature you built based on customer feedback."

Shows they listen and iterate. If they can't point to something specific, they don't have a strong feedback loop.

"What can't you do today that you wish you could?"

Reveals honest product gaps. Every startup has limitations. Founders who won't admit them are hiding something.

"Walk me through your tech stack and why you chose it."

Real engineers know their stack. Non-technical founders who claim to be "full-stack" should have a technical co-founder who can explain this.

"What's the biggest technical risk in the business?"

If they say "none," they're either lying or haven't thought about it. Every technical product has risks.

"How do you handle customer data, and what's your security posture?"

With GDPR, CCPA, and increasing security concerns, this is table stakes. If they don't have an answer, it's a red flag.

Category 3: Business Model & Metrics

"What's your current burn rate, and how far does it take you?"

Standard question. If they won't answer, they're either in worse shape than they claim or they're hiding something.

"What's your revenue split between new customer acquisition and expansion?"

Expansion revenue (upsells, cross-sells) is more efficient than new customer acquisition. Good founders know this ratio.

"What's your gross margin, and what does it look like at scale?"

Software businesses should have high gross margins (70%+). If they're at 40%, they better have a good explanation.

"Show me your cohort retention data."

Not MRR. Not ARR. Cohort retention shows whether customers stick around over time. If they can't show it, they might not have it.

"What's the lifetime value of a customer, and how did you calculate it?"

If they say "we haven't calculated it," that's a major red flag. Every SaaS business should know LTV.

Category 4: Team & Culture

"How do you make decisions when you and your co-founder disagree?"

Founders who can't answer this have a脆弱 co-founder relationship. In a startup, disagreements will happen.

"Walk me through your hiring process for the last person you hired."

Shows they care about hiring and have a process. Startups live and die by hiring quality.

"What's one hire you wish you'd made 6 months ago?"

Reveals what they feel is missing. If they say "no one," they might be overconfident.

"How do you handle it when someone on the team fails?"

Tests culture. Do they blame individuals or examine systems? Blame culture kills startups.

"What does the board do, and how often do you meet?"

If the board is dysfunctional, that will surface eventually. Better to understand the relationship early.

Category 5: Fundraising & Exit

"Who else are you talking to, and what's your timeline?"

Red flags: "We're not talking to anyone" (no competitive pressure) or "I can't tell you" (suspicious).

"What's your expected exit timeline, and what does that path look like?"

If they say "IPO in 3 years" without a clear path, they're delusional. Most good founders have a realistic view.

"What would have to be true for you to sell the company in 5 years?"

Tests flexibility. The best founders have both conviction and flexibility.

"If this company fails in 18 months, what will you do?"

Tests resilience and backup planning. Great founders have thought about this and have a plan.

"What terms from your last round would you change if you could?"

If they say "none," they might not understand what they signed. If they say "the liquidation preference," they learned something.

The Red Flag Responses

Problem & Market Red Flags

• "Our competitors are lazy/stupid" - dismissal without analysis
• "Everyone with a problem needs this" - TAM inflation
• "We've never lost a customer" - either lying or haven't been around long enough to lose any

Product Red Flags

• "Our tech is proprietary and I can't explain it" - either fake or they're not technical
• "We've never had a security issue" - everyone has had issues
• "The product does everything" - no clear focus

Business Model Red Flags

• "Growth is our only metric that matters" - ignores profitability
• "We don't track that" - amateur hour
• "Our margins are fine" - can't explain why

Team Red Flags

• "My co-founder is great at everything" - unrealistic
• "We don't need a board" - misses oversight
• "I'll fire anyone who fails" - blame culture

Fundraising Red Flags

• "We're in exclusive talks" - usually not true
• "The terms are standard" - can't explain the terms
• "We're raising because it's expected" - no strategic reason

The Follow-Up Framework

After the first meeting, always follow up with:

1. The question you didn't answer: Send a follow-up email with the one question they dodged. How they respond reveals character.

2. The reference you want: "I'd love to talk to 2-3 customers and 1 former employee." Watch how quickly they offer these.

3. The document you need: "I'd like to review the cap table and last board consent." Hesitation is a red flag.

4. The next step: "What's the timeline for your decision, and what would move the needle?" Clear timelines = professional.

Key Takeaways

1. Ask about failure - how founders handle failure reveals character
2. Push on numbers - vague answers to specific questions = red flag
3. Follow up - the question they didn't answer is the important one
4. Check references - talk to customers and former employees before deciding
5. Use Soloanalyst - get the pre-meeting arsenal before every first meeting
