Investor reference checks: a 3-question founder script

Your team is aligned, your tech is hitting milestones, and then the email lands: a term sheet from a venture firm you've been courting for what feels like forever. The instinct is to sign before they change their mind. I get it. The relief is real.

But here's the question I want you to sit with for a moment before you move forward: you are about to enter a partnership that could span anywhere from five to ten years. You would never hire a C-suite executive without checking references, understanding their track record, and learning how they behave under pressure. So why would you commit to a capital partner — someone who will sit on your board, shape your strategy, and influence every major decision — without doing the same homework?

Why the 5-to-10-Year Partnership Demands Reverse Due Diligence

Let me reframe what a term sheet really is. It's not a transaction. It's an invitation into a long, messy, deeply consequential relationship. VCs routinely conduct background checks on founders — they want to know about your previous ventures, your character under stress, whether your team has stuck together through hard patches. That's healthy and appropriate.

What's less common, and what I want to normalize for you, is the inverse: founders conducting serious reference checks on the investors they're about to commit to.

The asymmetry is real. When the partnership goes well, both sides benefit. When it goes badly — when there's a missed quarter, a brutal pivot, a near-death moment for the company — the investor's behavior becomes the single most important variable in whether you survive it. Their follow-through, their tone in board meetings, their willingness to lean in rather than bail out: these things determine your trajectory more than your original pitch deck ever did.

So let's talk about how to actually evaluate this before you sign.

The Art of Selecting the Right Portfolio References

Here's a trap I see founders fall into constantly: they ask the VC for references, and the VC happily provides three glowing testimonials from portfolio companies that are flying. Of course they do. Those founders are happy, they're funded, they're succeeding. The investor looks like a genius.

That tells you almost nothing.

What you need is a different kind of signal. Ask the investor to connect you with two specific portfolio founders: one who had a smooth trajectory and is thriving, and one whose company faced real hardship — a tough pivot, a near-death experience, a shutdown. You want both. You want the full spectrum.

The successful founder will tell you what it's like to work with this partner when things are going well. The founder who went through hard times will tell you what it's like when they weren't. That second conversation is where the truth lives.

If an investor hesitates to provide a reference from a struggling or failed portfolio company, that's information too. Pay attention to it.

The reference list a VC hands you is a highlight reel. The reference you actually need is the one who can tell you what happened in the dark.

The 3-Question Script for Uncovering Investor Crisis Conduct

Once you have your two portfolio founders on the phone (or on a video call — I know we're all distributed now), here's where most founders blow it: they ask soft, open-ended questions like "So, how does this investor help you?" or "What's it like working with them?" Those questions are essentially marketing prompts, and you'll get marketing answers.

You need to ask about behavior. Specific behavior. Past behavior under stress.

Here are the three questions that will give you the highest signal.

Question 1: "Can you walk me through a moment when the company was struggling — a missed quarter, a difficult pivot, a near-death experience — and describe specifically how this partner showed up?"

This is the heart of the whole exercise. You're not asking for general impressions. You're asking for a story. A moment. What did the investor actually do? Did they pick up the phone at 11pm? Did they help you think through the pivot strategy? Did they get cold feet and start questioning whether to fund the next round? Did they introduce you to the exact customer you needed?

Watch for specificity. If the founder pauses and says something vague — that the investor was generally supportive, or that they "checked in" — that's a yellow flag. Real follow-through leaves a mark people can describe in concrete terms.

Question 2: "Has there ever been a disagreement between you and this partner about strategy or direction? If so, how did it get resolved?"

This is where the boardroom dynamic reveals itself. Every founder-investor relationship will have moments of friction. The question is whether the investor treats those moments as collaborative problem-solving or as power plays. Did they listen? Did they push back constructively? Did they respect your decision even when they disagreed? Or did they threaten to withhold the next round, bring in other LPs to pressure you, or try to replace you?

This question also surfaces something founders often don't think to ask: how does this investor behave when they're wrong?

Question 3: "If you were starting a new company tomorrow, would you take this person's money again?"

This one sounds simple. It's devastatingly effective. It cuts through politeness, through the social pressure to be diplomatic about someone who gave you money. The honest answer — with whatever caveats come with it — tells you more than any other question you can ask.

If they hesitate, ask why. If they laugh and say "absolutely," ask what specifically would have made them say no. Both answers are useful.

Moving Beyond Marketing: Decoding Concrete Past Behaviors

There's a pattern I want you to recognize. When founders get generic answers from references — "they're great partners," "they open doors," "they're super supportive" — they often take that as a positive signal. It usually isn't. It's a sign that the reference either doesn't have deep experience with the investor's behavior in hard moments, or they're being polite.

What you're listening for instead is concrete, granular, slightly uncomfortable detail. The kind of answer a founder only gives when they're being honest. One pattern to listen for: the reference describes a specific moment of crisis and walks you through exactly what the investor did — a board call the morning after a missed quarter, a flight taken to sit alongside the founder during layoffs, a difficult reforecast worked through together line by line. Another pattern, less flattering but equally informative: the reference goes quiet when you ask about the hard stretch, or describes a period when the investor disappeared for weeks and stopped leading follow-on rounds.

That second kind of answer — the unflattering one — is the kind of clarity you actually need. It's not a reason to walk away automatically. Maybe that investor isn't right for early-stage hardware where capital intensity is brutal, but they might be perfect for a Series B SaaS play. The point is you now know. You're not walking into the relationship blind.

Past behavior is the only reliable predictor of future behavior — especially when that past involved stress, loss, or a crisis of confidence.

Some of the more rigorous investors in the ClimateTech space — firms like 81 Collection — are known to do ten or more backchannel reference checks before making a commitment. That's the level of seriousness we should be aiming for, even if you're running a lean pre-seed round and don't have the bandwidth for ten conversations. Even three to five well-chosen references, asking these specific questions, will completely transform your negotiating position and the clarity you walk into the partnership with.

Strategic Timing: When to Execute Your Reference Checks

Now let's talk about when to actually run this playbook, because timing matters more than you'd think.

The sweet spot is narrow but clear: after you've received a term sheet or a clear written offer, but before you sign anything. This is the window where you have leverage (they want you) but haven't yet locked in the commitment.

A few timing nuances worth naming:

Don't run reference checks during your first meeting. It signals distrust before there's anything to be distrustful about. Save this for after the term sheet lands.

Don't wait until you've already signed and the money is in the bank. Once you've signed, your leverage evaporates. If the reference checks surface something concerning, you want to still have the ability to walk away or renegotiate.

If the term sheet is conditional on speed — and they sometimes are, especially when an investor is worried about a competitive process — explain politely that you need a reasonable window (a week or two is usually fair) to do your diligence. Any investor who pressures you to skip this step is telling you something important about how they'll behave in a future crisis, when they want you to move fast and skip the careful part.

Don't skip this step just because you trust the partner's brand. Brand is not behavior. The most respected firms in climate have had portfolio companies that struggled, and the way those firms showed up in those moments is what actually matters. No firm name is a substitute for a real conversation.

Putting It All Together

I want to leave you with this: doing investor reference checks isn't about being suspicious or adversarial. It's about alignment. You're going to spend five to ten years with this person or this firm. You're going to bring them into the most stressful moments of your professional life. You're going to ask them for help when you don't know what to do.

The three-question script — the crisis question, the disagreement question, and the "would you take their money again" question — gives you a way to find out, before you commit, what it actually feels like to have them in the room when things are hard.

So here's your next step, if you're in the middle of a fundraise right now: pull up the term sheet you're considering. Find two portfolio founders — one successful, one who went through difficulty. Send them a short, warm note explaining that you're in the diligence phase and would value thirty minutes of their honest time. Then have the conversation. Not the polite one. The real one.

That single afternoon of work might be the most important thing you do all quarter. The partnership you choose will shape everything that comes next — for the technology you're building, for the climate impact you're trying to create, and for the team you've brought together to do it. It's worth the hour.
