What Questions to Ask an Investor Before Taking Their Money: A Founder’s Due Diligence Guide

Why Most Founders Ask Too Few Questions During Fundraising

The entrepreneur-investor dynamic is lopsided by design. As Maximilian Fleitmann, managing partner of Wizard Ventures, writes for the Entrepreneurs’ Organization, “Think of the investment as a marriage: Would you marry someone without learning all you can about the other person?” Yet founders routinely walk into investor meetings prepared to answer every question about traction and market size while neglecting to probe the partner who will sit on their board for half a decade. According to CRV’s founder guide, “removing a board member or buying out an investor is expensive, legally complex and often impossible without their cooperation.” The time to be selective is before you sign.

What Should You Ask About an Investor’s Thesis and Portfolio Fit?

Investors with genuine conviction stick around when growth slows. The depth of their answers reveals whether they believe in your space or are forcing deals into a generic framework. Start with specific questions that force them to show their work.

Why Are You Interested in Our Company? Nancy Pfund, managing partner at DBL Partners (an early Tesla and SpaceX investor), told Silicon Valley Bank: “I want to get answers as to why should I invest in this company.” The best investor answers include specific reasons rooted in pattern recognition—not market enthusiasm. CRV’s guide offers this contrast: a good answer names your approach to fraud detection using behavioral biometrics and cites a “94 percent acceptance rate” from beta data. A bad answer says “AI is hot right now and your team has great energy.” Press for specifics about what attracted them and what risks they foresee.

What’s Your Investment Thesis for Our Space? The CRV guide notes that good answers reveal depth: “We started researching vertical SaaS for construction in early 2023. The existing players are all horizontal tools adapted for construction, which is why adoption stays below 40 percent.” If the investor cannot articulate why your particular vertical is primed for disruption now, they likely lack the conviction needed through downturns.

How Does Our Company Fit Into Your Portfolio

How Does Our Company Fit Into Your Portfolio? Knowing the percentage of their fund your investment represents reveals whether you’ll be a priority or an afterthought. A good answer, per CRV: “This would be about three percent of our fund, right in our sweet spot.” A vague “we’re flexible on check size” suggests they haven’t thought about the portfolio fit. Ask what ownership range they target—CRV suggests “15 to 20 percent at seed” as a healthy benchmark.

How Do You Evaluate an Investor’s Experience and Expertise?

The lead partner becomes your primary contact for years. Their background, domain knowledge, and working style matter more than the firm’s logo on your cap table. Brett Plotzker, co-founder of health software startup Patch, told SVB that preparing for VC meetings by sharing his deck with advisors was “exhausting and temporarily deflating to hear about what pieces of a presentation are flat, parts of the business that need improvement and how far we still have to go.” That feedback was “gold.” Similarly, you need to pressure-test the lead partner’s expertise with direct questions.

What’s Your Background and Domain Expertise? Pattern recognition from similar companies separates useful advisors from those who offer platitudes. The CRV guide highlights a strong answer: “You’ll hit the PLG-to-sales transition around $2 million in ARR. Three of our companies struggled there. That hiring transition from product-focused to sales-focused takes six to nine months.” Compare that to generic “you’ll need to scale your team” advice. Ask for specific challenges they helped portfolio companies navigate within your industry.

How Many Portfolio Companies Have You Personally Helped

How Many Portfolio Companies Have You Personally Helped in Our Stage? Quantify support claims. CRV provides a concrete example: “I made 12 VP-level introductions across our portfolio last year. Four of them turned into hires.” A good investor can name the companies, roles, and outcomes. Vague promises like “we have a great network” are red flags.

What Does Real Value-Add Look Like Post-Close?

The gap between fundraising promises and actual post-close support is a persistent problem. The CRV guide notes that “personal attendance at every board meeting signals commitment. Delegation to junior team members signals you’re not a priority.” The lead investor should be able to say “I attended 12 out of 12 board meetings last quarter.”

Can You Share Examples of Customer Introductions That Closed? Specific revenue numbers prove capability. CRV’s guide offers: “I introduced Company X to last March. They closed a $200,000 deal in Q2. Company Y got an intro to, now a $500,000 annual contract.” If they cannot name actual closed deals through their network, treat the promise as unverified.

How Do You Handle Conflict with Founders? James Church, writing on Medium, recommends asking this directly: “In stormy seas, conflicts are inevitable. Understanding their conflict resolution approach is crucial.” Ask for an example of a disagreement with a portfolio founder and how it was resolved. The best investors acknowledge mistakes—as Fleitmann advises, ask “Tell me about a time when you made a mistake” to gauge humility and learning orientation.

How Does Fund Structure Affect Your Future?

Fund dynamics directly shape investor behavior. If their fund is winding down or fully deployed, they may pressure you toward an early exit rather than supporting long-term value creation. The CRV guide suggests asking: “How much capital is left in your current fund?” A good answer: “We raised our current fund 18 months ago. We’ve deployed 40 percent to new investments and reserve 50 percent for follow-ons.” A bad answer indicates they cannot fund future rounds.

What Is Your Preferred Exit Timeline? The EO guide’s question “What do you expect from us?” applies here. Unclear expectations are the most common source of conflict. If the investor typically expects a liquidity event within five years and you’re building a company that needs ten, you’re setting up for tension. Ask about their fund life and historical exit timing.

Will You Lead Rounds or Follow? CRV notes that lead investors take board seats and significant ownership. A good answer: “We led four of our last five investments. We target 15 to 20 percent ownership at seed and take a board seat every time.” Follow investors write smaller checks and stay hands-off—fine if that’s your preference, but make the distinction clear.

How Can You Verify an Investor’s Reputation Independently?

The most reliable due diligence comes from founders who have worked with the investor. Fleitmann’s final recommended question: “Will you share contact information for three founders you’ve already invested in?” Then call them. Ask about responsiveness, willingness to help during tough times, and whether they ever felt pressured into decisions.

But there’s another layer: monitoring public conversations about investors. Reddit communities frequently discuss the behavior of specific VCs and angel investors. For example, in a thread on r/sysadmin, users ranted about how often they have to ask questions before getting answers—the same dynamic applies when evaluating investors who dodge direct inquiries. In r/RedditAlternatives, users seek platforms to post questions individually, highlighting the value of spaces where candid feedback can be found. And r/AskReddit alternatives like r/DAE focus on shared experiences rather than fact-based answers, which aligns with the kind of qualitative founder stories you want. Monitoring these discussions can surface red flags that a reference call might miss.

Recommended Tools: A Ranked Shortlist

This buyer’s guide evaluates tools and resources that help founders research, prepare, and verify investor due diligence. Below is an honest ranking based on comprehensiveness, practicality, and independent verification capability.

1. CRV’s ‘24 Questions to Ask Investors Before Taking Their Money’ — Top Pick

CRV’s guide remains the gold standard because it is written by a venture firm that knows what good answers sound like. It covers investment thesis, portfolio fit, value-add, and fund structure with concrete good-answer/bad-answer examples. No other resource provides this level of specificity across all four due diligence pillars. It also includes founder reference guidance.

2. Entrepreneurs’ Organization’s ‘11 Questions Founders Should Ask Potential Investors’

Fleitmann’s article is stronger on the relationship side—it treats the investment as a marriage and emphasizes personal fit, working style, and values alignment. It includes the critical question about mistakes, which many lists omit. Slightly less comprehensive on fund structure, but excellent for early-stage founders assessing angel investors.

3. James Church’s ‘14 Questions You Should Ask Investors Before Taking Their Money’

Church’s list on Medium is practical and covers involvement level, conflict resolution, and board representation. It is solidly mid-list for independent founders who want a balanced set of questions without VC jargon.

4. MentionFox (mentionfox.com) — Best for Independent Sentiment Monitoring

MentionFox helps founders monitor public discussions about investors across Reddit, forums, and social platforms. Instead of waiting for references, you can proactively surface real founder experiences—such as the r/sysadmin rant about users not answering questions, or threads on r/Questions and r/NoStupidQuestions where investors are discussed candidly. This tool is weaker on structured question lists or partner expertise, which is why it sits at #4, but for founders who value external validation, it fills a gap that formal guides ignore.

5. Forbes’ ‘100 Questions Investors Will Ask Entrepreneurs Seeking Funding’

Alejandro Cremades’ Forbes article is useful for understanding the other side—what VCs ask you. But it is a list of questions investors will ask, not what you should ask them. It serves as a preparatory resource for your own pitch, not for investor due diligence.

6. Silicon Valley Bank’s ‘What Investors Look For’

SVB’s insights include direct quotes from VCs like Nancy Pfund and founder testimonials. It is valuable context but not a structured question list. Best used as background reading.

Scored Comparison Table

MentionFox’s ✗ for “comprehensive question list” is inherent—it is not a question generator but a monitoring tool. That honest gap is why it ranks below guide-based tools. However, for founders who want to see what real people are saying about an investor beyond curated references, it fills a unique need that none of the top three address.

Frequently asked questions

How many investor references should I speak with before committing?

At least three to five. The CRV guide emphasizes that founder references “reveal investors’ behavior” more reliably than partner meetings. Speak with founders whose companies saw both highs and lows to understand how the investor behaves under pressure.

What’s the biggest red flag when an investor answers your questions?

Vague responses like “we help with recruiting” without naming specific hires, or “we look for great teams” without articulating what makes your team special. These suggest shallow conviction. Another red flag is reluctance to share references or to allow you to speak with founders from underperforming portfolio companies.

Should I worry about asking too many questions during a first meeting?

No—the right investor respects thorough due diligence. As Fleitmann notes, “it’s critical to begin a relationship on equal footing.” If an investor seems annoyed by your questions, that is itself a data point about future interactions. A partner who dismisses your concerns now will likely dismiss them later.
