We Failed Our Due Diligence—Lessons Learned
You had a term sheet. The deal was moving forward. Then due diligence happened, issues surfaced, and the investor walked. It's brutal. But it's not the end. Here's how to understand what went wrong, recover, and come back stronger.

It's Not Over
First: a failed due diligence is not the end of your company or your ability to raise. Many successful companies had deals fall through before finding the right partner. The key is learning from it.
What You Need to Do Right Now
- Take a breath. This is emotionally hard. Give yourself a day before taking action.
- Get honest feedback. Ask the investor (or your intro) exactly what killed the deal.
- Document everything. Write down what happened while it's fresh.
- Assess your runway. How long do you have to fix this and try again?
Common Due Diligence Failures
Due diligence failures generally fall into a few categories. Understanding which one hit you is the first step to fixing it.
Financial Issues
- Messy books: Couldn't produce clean financials, or numbers didn't reconcile
- Revenue discrepancies: Reported revenue didn't match underlying data
- Undisclosed liabilities: Debts or obligations investor didn't know about
- Cash burn mismatch: Actual burn higher than what was communicated
- Unit economics don't work: Deeper analysis showed fundamentally broken model
Legal/Corporate Issues
- Cap table problems: Missing paperwork, unclear ownership, unresolved disputes
- IP issues: Unclear who owns the technology, missing assignments
- Compliance gaps: Missing contracts, tax issues, regulatory problems
- Founder vesting: Improper or missing vesting agreements
- Outstanding litigation: Legal issues that weren't disclosed
Business/Market Issues
- Customer verification failed: Customers told a different story than you did
- Churn discovered: Retention much worse than presented
- Market concerns: Reference checks raised competitive or market concerns
- Team issues: Reference checks on founders raised flags
Immediate Steps After Failure
In the first week after a failed deal, take these steps to stabilize and start recovery.
Get Detailed Feedback
Ask the investor (or your intro) for specific reasons. Not just "it wasn't a fit"—actual issues. Most will tell you if you ask directly.
Communicate with Existing Investors
If you have existing investors, tell them what happened honestly. They may be able to help with bridge capital while you fix issues.
Pause Other Active Processes
If you're talking to other investors, you may want to pause until you fix the issues. Word travels fast in VC circles.
Assess Your Runway
How long do you have to fix issues and re-engage? If runway is critical, address that first.
Document the Post-Mortem
Write down exactly what happened: what questions were asked, what issues surfaced, how you responded. This is your fix-it list.
Fix the Underlying Issues
Depending on what failed, here's how to fix it.
If Books Were the Problem
- Hire a startup-experienced bookkeeper/accountant
- Do a full reconciliation (see our guide)
- Generate clean financials that actually reconcile
- Have someone else verify the work
- Implement proper ongoing processes
If Cap Table Was the Problem
- Get a cap table management tool (Carta, Pulley)
- Hire a startup lawyer to clean up paperwork
- Resolve any outstanding disputes
- Ensure all agreements are properly executed
- Get legal sign-off before next raise
If Unit Economics Were the Problem
- Understand exactly what the investor found
- Recalculate metrics with rigorous methodology
- If metrics are actually bad, work on improving them
- Be honest about current state and trajectory
- Show a plan to improve, not just better spin
If Customer Calls Were the Problem
- Understand what customers actually said
- Address any legitimate concerns they raised
- Prepare a list of references who will speak positively
- Brief your best customers before future references
- Fix underlying product or service issues
Approaching the Next Investor
Once issues are fixed, here's how to approach your next fundraise.
Before You Start
- Run a mock due diligence yourself—would you pass now?
- Prepare complete data room before first meeting
- Brief your reference customers
- Consider what you'll say if asked about the failed deal
If Asked About the Previous Deal
Be honest but professional. Don't badmouth the previous investor. A good answer:
Proactive Disclosure
For any issue that was discovered, get ahead of it:
- "Here's our cap table—it's clean and here's our lawyer's confirmation"
- "Our books are reconciled through last month—here's the detail"
- "We've had some customer churn—here's what happened and what we've fixed"
How to Prevent This Next Time
Build systems that keep you due diligence-ready at all times.
Living Data Room
Maintain a standing data room that's always current. Update monthly. When investors ask, you're ready.
Monthly Close Process
Clean financials within 15 days of month end. Never be more than 6 weeks behind on your books.
Metrics Dashboard
Track key metrics weekly. Know your numbers cold so you're never surprised by what diligence finds.
Customer Health
Know which customers are happy and which aren't. Address issues before they become reference problems.
