Tag: investor due diligence

I’ve seen too many promising startups stumble. They weren't ready for the tough questions that come with raising capital. Due diligence isn't just for investors; it's a mirror for you, the founder. It helps you spot cracks in your own foundation before they become business-ending holes.

Think of it like building a skyscraper in Chicago. You wouldn't start without checking the blueprints, right? A good startup due diligence checklist is your blueprint. It’s how you prove you've built something solid, something an investor will trust, and most importantly, something that can actually last.

I created this 10-point checklist from real operator experience—the kind of hard-won knowledge we share in communities like Chicago Brandstarters. I want to help you get your house in order before you show it to the world. It’s for you, the kind, hardworking builder who is tired of being taken advantage of.

In this guide, you won't find generic advice. I'll walk you through everything, from your founding team's character to the hard numbers in your financial model. I'll use simple analogies to break down complex topics and give you actionable steps. This isn't about passing a test. It's about building a better, stronger company from the inside out. I want to help you stop guessing and start building with confidence. Let's get you ready for that next big meeting.

1. Founder Background, Character, and Alignment with Values

Before you look at a single spreadsheet, you must understand the founder. Think of it like this: you wouldn't build a house on a shaky foundation. In a startup, the founder is the foundation. Your integrity, resilience, and personal values will shape the company’s culture and its ability to survive a crisis far more than any business model.

This philosophy is the cornerstone of communities like Chicago Brandstarters, which supports "kind givers." The idea, from thinkers like Paul Graham and Naval Ravikant, is that long-term success is built on character, not just charisma. You’re looking for evidence of grit, generosity, and an authentic mission that goes beyond a quick payday.

How to Evaluate Founder Character

Your goal is to see the person behind the pitch deck. I look for consistent patterns of behavior over time.

• Observe Interactions: How do you treat your employees, a server at a restaurant, or even your competitors? Look for humility and respect.
• Discuss Failures: Tell me about a time you failed professionally. Do you take ownership and share lessons, or do you blame others? I find that founders who openly discuss their mistakes show maturity and strength.
• Check for Generosity: Do you have a history of mentoring others or contributing to your community? When you share credit with your team, you show a "we" versus "me" mentality, which is vital for building a great culture.

Key Insight: As Kevin Tao, founder of Chicago Brandstarters, often says, "We're not just betting on an idea; we're betting on the person's ability to lead with kindness and courage when things get tough." I want to know if you'll do the right thing, even when no one is watching. It’s the single most important predictor of a successful partnership.

2. Market Validation and Customer Demand

After you've assessed the founder, you need to confirm a real market exists for the product. An incredible founder with a product nobody wants is a recipe for failure. You must ensure you're solving a problem real customers will pay to fix. You need to find proof of demand before you spend significant time and money.

This is the core of the lean startup methodology. Instead of building in a vacuum, you test your assumptions with real people. If you're building an ecommerce brand, this might mean preselling a product before manufacturing. If you're a SaaS company, it's getting beta customers to pay a subscription fee, no matter how small. These early signals prove you're on the right track.

How to Evaluate Market Demand

Your mission is to find proof that customers want your solution, ideally with their time or money. I look for concrete evidence, not just optimistic projections.

• Conduct Customer Interviews: Talk to 20-30 potential customers. Your goal isn't to sell but to listen. Do they recognize the problem you're solving? How are they currently dealing with it?
• Track Willingness to Pay: During interviews, ask if they would pay for your solution. A "yes" is good, but a "Here's my credit card" is validation. Track how many people show real interest.
• Test with an MVP: Create a Minimum Viable Product or even just a landing page with an email signup. A Kickstarter campaign that funds your first production run is powerful validation—it uses real money to confirm demand.

Key Insight: Validation isn't a one-time event; it's a continuous process. Your goal is to de-risk your business by proving your core assumptions are correct. Are your early adopters just a small group, or do they represent a much larger market? Strong, early validation is one of the clearest signs you have a real shot at success.

3. Business Model and Unit Economics

After you understand the people, you must understand the math. A brilliant idea without a sustainable business model is just a hobby. You have to rigorously analyze how your company makes money, one customer at a time. This is about proving the core financial engine works before you pour fuel on the fire.

Pioneers like David Skok and Peter Thiel stress that you must grasp your business's fundamental arithmetic. Can you acquire a customer for less than the profit they generate? It doesn't matter if it's a subscription or a one-time sale; your unit economics must make sense. For example, a direct-to-consumer brand should aim for a Lifetime Value to Customer Acquisition Cost (LTV:CAC) ratio of at least 3:1. This ensures a healthy, scalable future.

How to Evaluate the Business Model

Your job is to model the financial reality of a single transaction and project it forward. Get into your spreadsheets and see if the numbers hold up under pressure.

• Model the Unit: Create a detailed spreadsheet. Break down the revenue and costs for your primary customer. What is your Customer Acquisition Cost (CAC)? What is the Lifetime Value (LTV)?
• Find the Break-Even Point: Calculate when your cumulative profits turn positive. How many sales does it take to recoup your initial investment and ongoing costs?
• Stress-Test Assumptions: Model multiple scenarios: a conservative case, a base case, and an optimistic case. How do your economics change if customer acquisition costs double?
• Track Real vs. Projected: As soon as you launch, start tracking your actual metrics against your projections. This shows me you understand how to operate a business, not just dream about one.

Key Insight: A common mistake is focusing only on revenue while ignoring unit profitability. If your CAC payback period is over 24 months, your unit economics are likely broken. A strong business model shows you can make money on each customer. This creates a foundation for profitable scale, not just a cash-burning machine.

4. Competitive Landscape and Defensibility

Once you understand the team and market, you must analyze the competitive battlefield. A great idea means nothing if it can't survive in a crowded arena. You need to know who you’re up against and what makes your business defensible. Think of it as building a moat around your castle. It’s not about being the first to build the castle; it’s about having a moat so deep that others can’t easily cross it.

This concept, from thinkers like Michael Porter and Peter Thiel, pushes you to find your sustainable advantage. You're not just looking for a temporary edge; you’re looking for a structural reason why you will win long-term. This is the difference between a fleeting success and a lasting enterprise.

How to Evaluate Your Competitive Moat

Your goal is to articulate why customers will choose you and keep choosing you, even when alternatives emerge.

• Map the Territory: Don't just list direct competitors. I want to see a simple map that includes indirect competitors (solving the same problem differently) and substitutes (other ways customers can get the job done). This gives you a full picture of the forces at play.
• Identify Your Unique Advantage: What is your "secret weapon"? For a DTC brand, it might be an authentic community that competitors can't replicate. For a SaaS business, it could be high switching costs. Be specific. "First-mover advantage" is not a moat; it's a head start that will quickly vanish.
• Test Customer Loyalty: Don’t just assume customers prefer you. Talk to them. Ask why they chose you over others. Was it because you were the only option, or because you offer something genuinely better? The answer reveals the true strength of your position.

Key Insight: As Peter Thiel wrote in “Zero to One,” your goal is to build a business so good it becomes a monopoly in its niche. Your defensibility isn't static; it should strengthen over time. A marketplace gains network effects with more users. A data-driven company gets smarter with every customer. This makes your moat wider and deeper as you grow.

5. Product-Market Fit and MVP Viability

After confirming your integrity, my focus shifts to the product. Product-Market Fit (PMF) is that magic moment when your solution perfectly meets a market's needs. Think of it as finding the one key that effortlessly unlocks a door. Before you get there, you have the Minimum Viable Product (MVP), a simple version of your product designed to test this fit with the least effort.

This concept, from figures like Marc Andreessen and Sean Ellis, is the core of any successful startup. It’s the difference between pushing a product uphill and having customers pull it from your hands. You are looking for clear signs that the product solves a real, painful problem, leading to enthusiastic adoption, strong retention, and organic growth.

How to Evaluate Product-Market Fit

Your goal is to find objective evidence that people truly want and need this product. You must look past vanity metrics like total signups and dig into actual user behavior.

• Track Retention Religiously: This is the truest indicator of PMF. For a SaaS tool, this could mean a net promoter score (NPS) above 50, showing users are active advocates. For a social app, I’d look for weekly active user retention above 40%.
• Analyze Word-of-Mouth Growth: When your product is great, people talk. Are more than 30% of your new users coming from organic referrals? This is a powerful signal that the product is solving a real need.
• Focus the MVP: A viable MVP solves one core problem exceptionally well, not ten problems poorly. For example, an e-commerce brand might prove PMF with a repeat purchase rate over 15% on a single hero product before expanding its catalog.

Key Insight: As Rahul Vohra of Superhuman showed, you can systematically measure and improve your fit. Ask your users how they would feel if they could no longer use your product. If over 40% say "very disappointed," you're on the right track. This part of your startup due diligence checklist confirms your business isn't just an idea; it's a necessity for its customers.

6. Founding Team Composition and Capability Gaps

If you as a lone founder are the foundation, your founding team is the entire frame of the house. A brilliant idea with a dysfunctional or incomplete team will collapse under pressure. A core part of your startup due diligence checklist is assessing your team's combined skills, their chemistry, and your plan to fill any critical gaps. You're not just backing individuals; you're backing a unit that must execute together.

This principle is a cornerstone of thinking from Y Combinator's Paul Graham to venture capitalist Brad Feld. They stress that the founding team is often a better predictor of success than the initial idea. An A+ team with a B- idea can pivot and win. A B- team with an A+ idea will likely fumble the execution. You are looking for a complementary blend of skills and a history of working well together.

How to Evaluate Team Composition

Your objective is to confirm your team has the right mix of expertise to build the product, find customers, and manage the business.

• Identify Complementary Skills: Look for balance. A classic successful pairing is a technical founder who builds and a business co-founder who sells. A team of three engineers with no one to handle marketing presents a significant risk.
• Assess Prior Relationships: Have you worked together before? Tell me about past projects, successes, and even conflicts. Teams with a proven ability to navigate disagreements are far more durable than a new group. If you're just starting, understanding how to find a co-founder with aligned values is a critical first step.
• Map Future Needs: Identify your most critical skill gaps for the next 12-18 months. Do you lack financial expertise? Do you need a marketing lead? A great founder will not only recognize these gaps but will have a credible plan to attract talent to fill them.

Key Insight: A strong founding team isn't about having all the answers. It's about having the self-awareness to know what you don't know and the magnetism to attract people who are smarter than you in those areas. My bet is on your ability to build a world-class team, not just a world-class product.

7. Financial Projections and Realistic Path to Revenue

A compelling story isn't enough; I need to see a credible map to financial success. This part of the startup due diligence checklist examines your financial model not as a crystal ball, but as a reflection of your strategic thinking. Your projections show how well you understand the levers of your business: what it costs to get a customer, how long they will stick around, and how you will eventually turn a profit.

This is not about having perfectly accurate numbers for year five. It’s about building a logical, bottom-up forecast grounded in solid assumptions. Thinkers like David Skok have shown that for SaaS companies, understanding unit economics like LTV to CAC is more critical than a top-down market size guess. Your financial model is your business plan in numbers. It shows you’ve thought through the hard parts of building a sustainable company.

How to Evaluate Financial Projections

Your goal is to show a realistic path from where you are now to future profitability, even if you have zero revenue today.

• Build from the Bottom Up: Instead of saying, "We will capture 1% of a billion-dollar market," start with your planned activities. For example, "We will run ads generating 1,000 leads per month at a 2% conversion rate, yielding 20 new customers."
• Model Different Scenarios: Create conservative, base, and optimistic forecasts. This shows me you understand that plans change and have considered a range of outcomes.
• Track Your Runway: Calculate your monthly cash burn and determine your runway—how many months you can operate before running out of money. For example, if you have $200,000 in the bank and burn $20,000 per month, your runway is 10 months. This is a vital metric.

Key Insight: As venture capitalist Vinod Khosla says, the assumptions behind your numbers are more important than the numbers themselves. A founder who can clearly articulate and defend assumptions about customer acquisition cost and churn rate shows a deep command of their business and a credible plan for growth. Your projections are a test of your operational intelligence.

8. Intellectual Property and Legal/Regulatory Compliance

After understanding the people, you must secure the castle's walls. Your startup’s intellectual property (IP) and legal compliance are the moat and fortifications that protect your core value. Without clear ownership of your IP and a clean legal bill of health, you are building on contested ground, vulnerable to lawsuits or regulatory shutdowns.

This part of your startup due diligence checklist is about proving you have a defensible, legal right to operate and own your creation. Pioneers in the venture space like Brad Feld and accelerators such as Y Combinator constantly stress this. They know that a single overlooked IP claim from a founder’s past employer or a failure to comply with data privacy laws can instantly sink an otherwise promising company.

How to Evaluate IP and Compliance

Your goal is to ensure you own your "secret sauce" free and clear, and that you aren't unknowingly breaking any rules.

• Audit Your IP Assets: What are your key innovations? For a software company, this might be a unique algorithm. For a consumer brand, it's the name and logo. You must identify and protect these assets.
• Trace IP Ownership: Confirm all IP created by founders, employees, and contractors has been legally assigned to your company. A common pitfall is a founder who started coding a project while still at a previous job, potentially giving that ex-employer a claim to the IP.
• Review Regulatory Exposure: Does your business touch on regulated areas? A fintech app has financial compliance, a health tech product has HIPAA, and any company with user data must consider privacy laws like GDPR or CCPA. For example, a marketplace platform must be crystal clear on whether its providers are contractors or employees to avoid massive legal trouble.

Key Insight: As many Techstars mentors advise, "Legal diligence isn't about finding problems; it's about preventing them." Clean IP documentation and proactive compliance aren't just legal busywork. They are foundational assets that create tangible value and de-risk the entire venture for you, your team, and future partners.

9. Scalability and Path to Seven Figures Revenue

An idea that works for your first ten customers must also work for your next ten thousand. A critical part of any startup due diligence checklist is assessing scalability—your business’s ability to grow exponentially without its structure collapsing. Can your model realistically get to seven figures in annual revenue, or will it break under pressure? You're looking for a strong engine, not just a car that looks good in the driveway.

This focus on intentional growth is fundamental to thinkers like Peter Thiel, with his emphasis on 10x thinking, and Paul Graham, who provides countless growth tactics. The core principle is leverage: finding a business model where your inputs don't have to grow at the same rate as your outputs. For communities like Chicago Brandstarters, a key goal is helping founders build the systems needed for this journey, a topic explored in their guide to scaling your business.

How to Evaluate Your Path to Scale

Your objective is to map out a believable route from your current revenue to $1 million and beyond. This isn't just wishful thinking; it’s about identifying the real-world constraints.

• Model the Math: Create a spreadsheet that models your path to seven figures. What are your key assumptions? For a SaaS business, this means tracking customer acquisition cost (CAC) and lifetime value (LTV). For an e-commerce brand, it's about average order value and repeat purchase rate. Do the numbers hold up at 100x your current volume?
• Identify the Bottleneck: Every business has a primary scaling constraint. Is it your market size, customer acquisition, operational capacity, or access to capital? Pinpoint your biggest hurdle and make a plan to overcome it.
• Stress-Test Your Operations: If your service business relies entirely on you, the founder, it can't scale. You must design a system where a team can deliver the same quality. For example, can you productize a service or build a training program that allows new hires to be effective quickly?

Key Insight: The difference between a small business and a scalable startup is leverage. Ask yourself: "What is the one activity that, if I put in 10% more effort, will yield 10x the results?" Focusing on that single point of leverage is how you build a business that grows while you sleep, not one that requires you to be awake 24/7.

10. Founder's Execution Ability and Track Record

An incredible idea is just a starting point. Your ability to execute that idea is where real value is created. Many startups fail not because their vision was flawed, but because the team couldn't build, ship, and adapt fast enough. Evaluating your execution ability is a core part of any serious startup due diligence checklist. It reveals your capacity to turn plans into reality, especially when resources are scarce.

This focus on doing over dreaming is championed by people like Paul Graham and Naval Ravikant, who stress that the best founders have a strong "bias toward action." You aren't just looking for someone who can create a perfect plan. You're looking for an operator who can navigate uncertainty, inspire a team with limited capital, and consistently deliver on commitments.

How to Evaluate Execution Ability

My goal here is to find concrete proof that you can get things done. I look for a history of accomplishment, not just ambition.

• Review Past Projects: Show me specific examples of difficult projects you’ve completed. Did you ship multiple products, even if some failed? A founder who has built something, learned from feedback, and iterated shows a pattern of execution.
• Assess Resourcefulness: How have you achieved big results with a small budget or team? I look for evidence that you can recruit talented people based on vision alone, a key skill in the early days.
• Analyze Decision-Making: Tell me about a time you had to pivot based on new data. Do you stubbornly stick to your original plan, or are you flexible enough to adapt? The ability to change course is a sign of strength, not weakness.

Key Insight: At events hosted by communities like Chicago Brandstarters, I can see this firsthand. A founder who follows up on every promise and consistently helps others is showing their execution DNA. It's about finding the person who not only dreams big but also rolls up their sleeves and makes it happen, day after day.

You're Ready. Now Go Build.

We've walked through a mountain of information. Let's be honest, staring at a comprehensive startup due diligence checklist like this can feel overwhelming. It might seem like just another set of hurdles. But I want you to reframe that thought completely.

This isn't about creating more work. This checklist is a map. It’s your strategic guide to moving faster and building with confidence. Think of it like a pilot's pre-flight check. You don't do it because you expect the plane to fall apart; you do it so you can fly with the certainty that every part is ready for the journey.

Turning Knowledge into Action

Your goal isn't to get a perfect score. You don't need a flawless answer for every item, especially if you're just starting. The true value is in the self-assessment.

Where are your blind spots? Are you focused on product but not market validation? Do you have a killer team but a fuzzy understanding of your unit economics? This checklist gives you the power to be brutally honest with yourself, identify the weak links, and then get to work.

The most successful founders I know aren't the ones who had all the answers from day one. They are the ones who were relentless about finding the right questions and then executing on the answers.

Your next steps are clear. Don't just read this list; use it.

1. Prioritize: Go back to the prioritization section. Identify the top 3-5 items most critical for you right now.
2. Assess: Give yourself an honest grade. Where are you strong? Where are you genuinely weak? Write it down.
3. Execute: For each weak point, define one or two concrete actions you can take this month to improve. Is it interviewing 10 more potential customers? Is it building a more detailed financial model? Is it filing for that provisional patent?

This process transforms due diligence from a passive exercise performed on you into an active tool you use to build a stronger company. By preparing these documents and thinking through these areas, you are not just getting ready for a meeting; you are building a fundamentally better business. You are stress-testing your own assumptions before someone else does it for you in a high-stakes pitch.
