Before investing in a startup or joining a founder’s project, use this due diligence checklist to spot fraud risks, fake traction, and unsafe money flows.
Startup scams are especially dangerous because they can look legitimate.
A founder can have a polished pitch deck, a good domain name, a professional logo, a prototype, impressive language, and a network of respected contacts. The company may sound innovative. The market may sound large. The opportunity may sound urgent.
But none of that proves the business is real.
If you are thinking about investing in a startup, advising a founder, accepting equity, joining as a co-founder, extending credit, providing services, or introducing the founder to your network, you need a due diligence process.
This checklist is designed to help you avoid the most common founder-led scam patterns.
# 1. Verify the legal entity
Start with the basics.
Ask:
* What is the exact legal name of the company?
* Where is it incorporated?
* When was it incorporated?
* Who are the directors or managers?
* Who owns the company?
* Is the company active and in good standing?
* Are there related entities with similar names?
Red flags:
* The founder gives different company names in different conversations.
* The company is “in process” but not actually registered.
* The founder asks you to wire money before the entity exists.
* The company name on the contract does not match the bank account.
* There are multiple entities and no clear explanation of ownership.
A legitimate company should have clean corporate records. If the founder cannot provide them, stop.
# 2. Confirm who controls the bank account
Many startup fraud cases begin with investor money being sent into an account controlled by one person.
Before sending money, confirm:
* The account is in the company’s legal name.
* The receiving bank matches the company jurisdiction or has a clear business reason.
* More than one person has oversight.
* There is an accounting process.
* Investor funds will not be mixed with personal funds.
* There is a written use-of-funds budget.
Avoid sending money to:
* Personal bank accounts
* Accounts in another person’s name
* Newly created entities with no operating history
* Accounts where the founder refuses transparency
* Crypto wallets without formal controls
* Cash-based arrangements
If you cannot trace where the money goes, do not send it.
# 3. Require a use-of-funds schedule
A founder should be able to explain exactly how investor money will be used.
A proper use-of-funds schedule should include:
* Product development
* Engineering
* Sales and marketing
* Legal and accounting
* Inventory or operating costs
* Salaries
* Technology costs
* Office or administrative expenses
* Reserve funds
* Milestone timing
Red flags:
* “General operations”
* “Market expansion”
* “Launch costs”
* “Business development”
* “Founder expenses”
* “We will figure it out after funding”
Vague categories are not enough.
If the founder wants your money, they should be able to show what the money will buy, when it will be spent, and how progress will be reported.
# 4. Test the customer and revenue claims
Fake traction is one of the most common startup scam tactics.
A founder may claim:
* Major retailers are using the product.
* A large brand has approved a pilot.
* Revenue is about to start.
* Customers are waiting.
* A major partnership is signed.
* A big investor is interested.
* The product is already deployed.
Your response should be simple: prove it.
Ask for:
* Signed customer contracts
* Purchase orders
* Invoices
* Bank records showing collected revenue
* Customer references
* Pilot agreements
* Implementation screenshots
* Product usage reports
* Renewal data
* Sales pipeline details
Do not accept vague statements such as “we are in discussions” or “they love the product.” Discussions are not revenue. Interest is not a contract. A logo on a slide is not proof.
# 5. Verify the founder’s background
A founder’s history is relevant when money, equity, or trust is involved.
Check:
* Prior companies
* Lawsuits
* Criminal records
* Bankruptcy records
* Investor disputes
* Employment history
* Education claims
* Professional licenses
* Media mentions
* Public complaints
* Court records
* Former partner feedback
Do not rely on founder-selected references only. Ask to speak with prior investors, vendors, employees, and co-founders.
Specific questions to ask references:
* Did the founder do what they promised?
* Were funds handled properly?
* Were financial reports provided?
* Were contracts honored?
* Were there disputes?
* Would you work with this person again?
* Is there anything you wish you had known earlier?
The last question is often the most important.
# 6. Review the documents before the money moves
Do not send money based on a pitch deck alone.
Before investing, review:
* Subscription agreement
* Shareholder agreement
* Operating agreement
* Cap table
* Board approvals
* Financial statements
* Tax filings
* Bank statements
* Intellectual-property assignments
* Employment agreements
* Vendor contracts
* Customer contracts
* Debt agreements
* Litigation disclosures
If the documents are “coming later,” the money should also come later.
Paperwork is not bureaucracy. It is protection.
# 7. Watch for founder behavior that signals risk
Fraud risk is not only in the documents. It is also in behavior.
Red flags include:
* Anger when questioned
* Refusal to provide documents
* Overuse of famous names
* Constant urgency
* Changing stories
* Personal financial distress
* Excessive lifestyle claims
* No independent accountant
* No board oversight
* No clear ownership records
* Heavy use of secrecy
* Pressure to keep the opportunity private
* Promises of guaranteed returns
* Requests for cash or personal loans
A serious founder welcomes serious due diligence. A risky founder tries to bypass it.
# 8. Protect yourself as an advisor or vendor
Investors are not the only people who get harmed.
Advisors, consultants, agencies, lawyers, accountants, vendors, and employees can also be pulled into bad situations.
Before providing work, introductions, or credibility, ask:
* Is the company funded?
* Who is paying invoices?
* Is there a signed contract?
* Is payment tied to vague future fundraising?
* Are you being asked to work for equity?
* Is the equity documented?
* Are you being asked to introduce investors before verifying the company?
* Could your name be used to create false credibility?
Do not let someone use your reputation as bait.
# 9. Use a simple decision rule
Before you commit, answer these questions:
1. Can I verify the company exists?
2. Can I verify the founder’s background?
3. Can I verify the product exists?
4. Can I verify customer traction?
5. Can I verify where the money goes?
6. Can I verify the terms in writing?
7. Can I verify independent references?
8. Can I walk away without pressure?
If the answer to any of these is no, slow down.
If the founder refuses to fix the gaps, walk away.
Bottom line
A startup can be risky without being fraudulent. But fraud risk rises sharply when a founder asks for trust while avoiding verification.
Your job is not to predict the future. Your job is to verify the present.
Before you invest, advise, introduce, lend, or work for equity, demand documents, controls, and independent proof.
A good founder will respect that.
A bad one will resent it.
That difference tells you a lot.
