Due Diligence on the Team: What Background Checks Actually Cover
The team is the #1 predictor of startup success. According to Crunchbase data, repeat founders who have previously exited raise at 2x the valuation of first-time founders and have 3x better outcomes. The problem: most "team verification" at the angel stage is superficial — a quick LinkedIn glance and a reference call.
A real team background check goes deeper. It verifies not just where someone worked, but what they actually did, how their previous companies performed, and whether there are patterns of behavior that predict future problems.
This guide covers what systematic team verification looks like.
Employment History Verification
The Basics
For each founder, verify:
- Dates of employment — do LinkedIn dates match the founder's claimed timeline?
- Titles — were they actually a "co-founder" or a "team member"?
- Company reality — did the company exist, raise funding, and perform as described?
The Deep Dives
Former company outcomes: If a founder claims to have built a successful startup, check:
- Crunchbase: Did the company raise funding as claimed?
- What happened to it? Exit, shutdown, pivot?
- Were there layoffs or controversies?
Role authenticity: A "co-founder" who joined on day 1 and raised $0 is different from a "co-founder" who was added 2 years in with a small equity grant as a retention incentive.
The question to ask: "What was your actual role, and what did you personally build?"
Patterns That Signal Risk
| Pattern | Risk Level | What to Do |
|---|---|---|
| Employment gaps > 6 months unexplained | Yellow | Ask in reference call |
| Job titles don't match LinkedIn | Yellow | Verify with reference |
| Company claimed doesn't exist in Crunchbase | Red | Pass or get explanation |
| Previous company failed with no lessons learned | Yellow | Ask what they'd do differently |
| All roles were short tenure (< 1 year) | Yellow | Check for pattern of leaving |
Education Verification
The Basics
- Degree completion — did they actually graduate, or "attended"?
- Institution — does the school exist? Is the program accredited?
- Timing — did they attend during the claimed years?
Where to Verify
- LinkedIn education verification badge (if present)
- Direct inquiry to alumni office (most will confirm basic facts for a fee)
- Court records if degree fraud is suspected
Patterns That Signal Risk
| Pattern | Risk Level |
|---|---|
| "Attended" listed as degree | Yellow |
| Online certificate listed as graduate degree | Yellow |
| School doesn't exist | Red |
| Degree from unaccredited institution | Yellow |
| Executive education listed as advanced degree | Yellow |
Legal and Court Records
What to Check
- Federal court records (PACER) — for any litigation history
- State court records — varies by state, most have online search
- SEC/DOJ actions — for regulatory violations
- Bankruptcy records — for founder or previous companies
How to Search
- PACER: pacer.uscourts.gov (free to search, small fees for documents)
- State courts: Most states have online case search (search "[state] court records search")
- UnICourt: Aggregates court records (paid, but worth it for serious deals)
Patterns That Signal Risk
| Pattern | Risk Level | What to Do |
|---|---|---|
| Minor civil dispute (debt, landlord) | Yellow | Context needed |
| Pattern of litigation as defendant | Yellow | Assess severity and pattern |
| Securities fraud or financial crimes | Red | Pass |
| Bankruptcy (founder personally) | Yellow | Was it business failure or personal? |
| Non-compete enforcement | Yellow | Was the non-compete valid? |
Social Media and Digital Footprint
What to Look For
A founder's digital presence tells you something — not whether they're good people, but whether they have a coherent professional identity.
Patterns that are neutral:
- Active professional presence on LinkedIn
- Consistent personal brand over 3+ years
- Content that demonstrates domain expertise
Patterns that are yellow flags:
- No digital footprint before the startup
- Follower count completely disconnected from engagement
- All content is promotional with no personal perspective
- Sudden pivot to new domain with no prior signal
Patterns that are red flags:
- Evidence of misleading claims (review manipulation, fake customers)
- Pattern of customer complaints
- Evidence of burning bridges with previous employers
Reference Checks That Actually Work
The Standard Reference Call Fail
Most reference calls are useless because founders only provide investors who will say positive things. A good reference check:
- Asks specific questions about the person's character and competence
- Doesn't announce itself as a reference check (if possible)
- Cross-references claims with multiple data points
Questions That Work
For professional references:
- "In what capacity did you work with [founder], and for how long?"
- "What were their greatest strengths and most significant weaknesses?"
- "How do they handle conflict, pressure, or disagreement?"
- "Would you invest in them again as a founder?"
For customer references:
- "How did you find [company]?"
- "What problem does it actually solve for you?"
- "What would you change if you could?"
- "Would you recommend them to a peer?"
For character references (ask indirectly):
- "Did you ever see them in a situation where they had to choose between short-term and long-term interests? What did they choose?"
- "What's something about them that wouldn't show up on a resume?"
