We created this due diligence checklist for one simple reason: most fundraising delays don’t occur during the pitch; they happen during due diligence.
Investors expect clean numbers, clear documents, and a consistent story, but most founders rarely have all of that ready when the term sheet arrives.
This guide breaks down exactly what investors look for and how to prepare for due diligence before it even starts. Both investors and founders can use this checklist to run a faster, smoother process with fewer surprises and clearer expectations.
Let’s dive in!
What is a due diligence checklist?
A due diligence checklist is simply a structured list of documents, insights, and proofs investors ask for when evaluating a company before they put money in. It shows you what to expect from the process and what you need to prepare as a founder.
In this due diligence checklist, we’re going to speak about:
financial records
legal due diligence
product and technology
operational due diligence
business due diligence
GTM performance
team and HR
market competitiveness
This checklist focuses on startup fundraising. However, it’s not the only area where due diligence takes place. It’s actually used everywhere where risk meets capital:
M&A: Buyers review the target before acquisition
Strategic partnerships: Companies verify compatibility
Lending: Banks and credit providers assess risk
Private equity deals: Deep financial and operational investigations
So, the main principle is to verify the facts before making any meaningful decision.
In VC due diligence, the process is usually faster and lighter than in M&A; yet, the stakes are no smaller. Investors want to know your business is real, scalable, and ready to deploy capital effectively.
A teardown of the due diligence checklist for startups
Here’s a clear breakdown of the core areas investors dive into during due diligence and what they expect to see in each.
1. Company & corporate
Here, investors confirm the foundation of your business. They want to make sure the company actually owns what it claims to own, and that the structure is clean enough to invest in.
What’s reviewed:
Articles of incorporation & bylaws
Shareholder and board agreements
Previous financing documents (SAFEs, convertible notes, priced rounds)
Cap table (showing full ownership, including all convertibles and the option pool)
Founder agreements, vesting schedules
Advisor agreements
IP assignment agreements from founders, employees, and contractors
Why this matters:
A messy structure is a top reason investors slow down or walk away. If your cap table doesn’t match your verbal story, or if a past contractor still owns part of your codebase, that’s a major red flag.
2. Legal & compliance
Legal due diligence ensures that nothing in your business introduces hidden risk. Most early-stage startups underestimate this part until investors start asking questions.
What’s reviewed:
Customer contracts & major vendor agreements
NDAs, MSAs, partnership agreements
Terms of service and privacy policy
GDPR/CCPA compliance basics (especially for SaaS)
Trademark registrations, patents, and IP filings
Compliance with local regulations
Pending or past disputes
Why this matters:
Investors want to avoid liabilities, future lawsuits, or compliance issues that could block scale or acquisition. Even at Seed or Series A, they need confidence that the legal foundation is safe.
3. Financials
During financial due diligence, investors verify whether the business model and financial engine actually work in real life.
What’s reviewed:
Historical financial statements (P&L, balance sheet, cash flow)
Current cash position & runway
Monthly burn
Revenue breakdown: recurring vs one-off
Gross margin trends
Pricing structure
Cohorts and retention
Financial projections + assumptions
Capital structure & outstanding instruments
Why this matters:
Investors want to know whether the company is capital-efficient, scalable, and sustainable. They want to make sure that your deck, model, CRM, and actual numbers tell the same story.
4. Traction, commercial & GTM
Investors also want to evaluate whether your growth is real and repeatable (not just founder-led sales or a few lucky deals).
What’s reviewed:
Customer list (anonymized if needed)
Revenue concentration
Churn & retention metrics
Net revenue retention (NRR)
Sales funnel, win rates, and pipeline health
Sales cycle length
CAC by channel
Channel mix and scalability
Marketing attribution and efficiency
Top customer references
Why this matters:
If your financials show what happened, your GTM engine shows why it happened and whether it can scale. And investors are eager to see that your business has the potential to expand.
5. Product & technology
This is not only a technical review; it’s a check on product maturity, roadmap clarity, and defensibility.
What’s reviewed:
Live demo or product walkthrough
Product maturity (MVP, v1, enterprise-ready?)
Core features and differentiators
Product performance data
Roadmap for next 12–18 months
Tech stack
Architecture overview
Integration dependencies
Data privacy & security standards
IP ownership
Technical debt & risks
Why this matters:
VCs seek to know whether your product is real, scalable, and defensible. A weak product story can kill a deal even if the traction is good because buyers and competitors will crush you later.
6. Market & competition
This block covers everything related to market opportunity and your positioning.
What’s reviewed:
Market segmentation
Market growth trends
Key drivers and barriers
Competitive landscape (direct + indirect)
Your differentiation and defensibility
Why this matters:
Investors chase big markets, clear whitespace, and a credible path to leadership. Even great startups struggle when the market isn’t there.
7. People & HR
Yes, the “team slide” in your pitch deck is not enough. In due diligence, investors dig deeper.
What’s reviewed:
Founder bios & track records
Role clarity and division of responsibilities
Time commitment of each founder
Team structure and org chart
Employee agreements & option grants
Culture, turnover, and hiring plan
Recruitment pipelines
Why this matters:
Early-stage investing relies heavily on the people behind the wheel. So, investors want to know whether your team can execute the vision and scale the organization.
8. Operations & risk
This is especially important for hardware, AI, deep-tech, and companies selling into enterprise.
What’s reviewed:
Operational processes
Finance operations (billing, reconciliation, collections)
CRM and analytics infrastructure
Vendor dependencies
Supply chain risks
Business continuity or disaster recovery (for later stage)
Security practices
Internal controls
Why this matters:
Investors try to understand the operational bottlenecks and hidden risks that may not appear in the pitch but will definitely appear during scaling.
Why this due diligence checklist matters and who needs it
Due diligence can slow down a deal when documents are scattered or incomplete. A structured checklist helps you prepare everything in advance, makes the review more transparent, and reduces unnecessary back-and-forth between founders and investors.
This checklist is useful for:
Startups raising funds at any stage
VCs and angels assessing a company
Internal teams that need a central record of all business-critical information
Companies preparing for larger transactions, including M&A
How to prepare for due diligence
If you prepare early for due diligence, it won’t be so painful. A bit of upfront organization can save you weeks of back-and-forth later. Below, we’ve listed some of the steps you need to take to get ready:
Step #1: Build your data room before you start outreach
The biggest mistake founders make is waiting for investors to ask for documents. By that point, it’s already stressful. That’s why a good data room should exist before you plan to reach investors.
At minimum, it should include your deck, financial model, traction metrics, product demo, GTM KPIs, legal documents, IP assignments, key contracts (anonymized if needed), and a tear sheet for a quick company overview.
In fact, you don’t need anything fancy; just a clean, logical folder structure.
Step #2: Align your story across every material you share
Inconsistencies are the last thing you need during due diligence. A CAC in the deck doesn’t match the model? An ARR figure in the CRM that doesn’t correspond to what was said on the call? Even small gaps like these can raise red flags for investors.
That’s why you’d better take one day to sit down with your model, pitch deck, CRM, and investor narrative to make sure metrics reconcile, definitions match, and the story feels coherent.
Step #3: Clean up your cap table
Cap tables cause more issues in due diligence than anything else. Missing signatures, old SAFE terms, option pools that weren’t actually approved, or a surprise 2% shareholder who appears late in the process. These things slow down deals and sometimes can even kill them.
Before DD begins, review every instrument, confirm conversions, and clean up the ledger. And one more thing, make sure you can explain the fully diluted structure simply.
Step #4: Prepare customer references in advance
Investors will almost always ask to speak with customers. Even two or three short conversations can help the DD process significantly, especially if customers can articulate ROI, the problem you solve, and why they chose you.
It’s also helpful to prepare supporting customer feedback in advance: NPS scores, testimonials, usage insights, or short case studies. These give investors a broader picture of customer sentiment.
Step #5: Be ready to explain your numbers
You don’t need to be a finance expert, but you do need to understand the basics of how your business makes and spends money. During due diligence, investors will ask about things like your unit economics, margins, churn, pricing, burn, and runway. And if you can’t explain clearly why these metrics move the way they do, investors will have to dig deeper, which slows everything down.
Where Waveup can help
Most teams don’t struggle with due diligence because the business is weak; they struggle because the story, numbers, and documents aren’t fully aligned. We see this every day across the fundraising and M&A work we do.
At Waveup, we’ve supported hundreds of companies through raises and transactions, from early rounds to $100M+ deals. Our team has built, scaled, and exited businesses themselves, and many come from VC and M&A backgrounds. That mix gives us a clear view of what investors actually look for and which gaps tend to stall the process.
Because of that, our work is very hands-on. We help founders prepare the materials (pitch deck, financial model, business plan, etc.), raise, and grow their business. Contact us and let’s discuss the details.

FAQs
What is due diligence in fundraising?
Due diligence is the process investors use to confirm that your numbers, claims, and story match reality. It’s where they dig into your financials, traction, product, legal setup, and team to understand the risks and the true potential of the business. In fundraising, DD typically happens after a term sheet.
What documents do investors ask for during due diligence?
It varies by stage, but most investors want to see your pitch deck, financial model, traction data (revenue, churn, cohorts, and pipeline), product materials or a demo, legal documents such as incorporation papers and shareholder agreements, IP assignments, a clean cap table, and key contracts or policies.
Do early-stage startups really need a due diligence checklist?
Yes. Even if investors request fewer documents at seed or pre-seed, they still expect clarity and consistency. A due diligence checklist simply helps you stay organized, avoid last-minute surprises, and present a clean, confident picture of the business.
Should I give investors full access to everything immediately?
No. Most founders use a phased approach. Early on, you share the essentials, such as your deck, model, and core metrics. After a term sheet, you provide deeper access to legal docs, contracts, and sensitive information.
