A Checklist for Technical Due Diligence for Startups

Startups are more prevalent than ever, fueled by a surge of innovative ideas and entrepreneurial energy. However, turning a great idea into a successful business requires more than creativity—it demands capital. Investors, understandably cautious, typically won’t commit funds without thorough due diligence. That’s why conducting technical due diligence is essential for startup founders.

If you're preparing a pitch deck, it's crucial to have a deep understanding of every aspect of your business. Be ready to articulate your long-term vision, anticipate potential challenges, define your market position, and even explain the technical foundation—down to the codebase. Many startups struggle with this process due to day-to-day demands and limited resources.

To help you get started, here’s a checklist to guide your technical due diligence preparation.

What Is Technical Due Diligence?

Technical due diligence is a comprehensive evaluation of a startup’s:

• Technology
• Finances
• Product
• Management
• Architecture

Investors typically conduct technical due diligence before mergers and acquisitions (M&A) or funding rounds to inform their decision-making. The process helps:

• Assess the quality of the product’s current codebase
• Determine whether the technology and team can scale
• Identify red flags before committing to an investment

Who Conducts Startups Technical Due Diligence for Startups?

Ideally, technical due diligence should begin before you attract investor attention. However, many startups lack the time and internal resources to manage this process effectively. That’s why working with experienced professionals—like those on our team—can be invaluable.

We recommend developing strong documentation habits early on, including:

• Code backups
• System architecture diagrams
• Meeting minutes
• Invoices
• Operational workflows

Store this information in a centralized, accessible location so it’s ready when needed. The scope of due diligence depends on your startup’s size and the type of investor. Smaller startups may only require one-on-one meetings, while larger ventures involved in M&A deals may face scrutiny from lawyers, accountants, and technologists. Investors may also hire third-party experts with legal and technical expertise.

Sensitive Information Revealed During Due Diligence

Technical due diligence often involves sharing sensitive data, such as:

• Trade secrets
• Proprietary algorithms
• Forecasting models
• Commercial strategies
• Intellectual property

To protect your business, consider signing a non-disclosure or confidentiality agreement before engaging in due diligence discussions.

When is Technical Due Diligence Required?

Technical due diligence is most commonly initiated during financial investment rounds. Individual investors, private equity firms, and venture capitalists may require it at various stages:

1. Pre-Seed – Market testing after product development
2. Seed – Product meets initial consumer needs
3. Series A – Product is scaling successfully
4. Series B – Product has a strong market presence and brand recognition

Startup Technical Due Diligence Checklist

Every startup and investor is different, so there’s no universal checklist. However, here are key elements to prepare:

• Product designs, features, and capabilities
• Team structure and roles
• Technology stack and system architecture
• Development methodology (e.g., Kanban, Scrum)
• Deployment approach (e.g., manual, CI/CD)
• System workflow diagrams
• Monitoring and alert systems
• SaaS and third-party tool inventory
• Quality assurance processes
• Backup and disaster recovery plans
• IT best practices
• Competitive analysis
• Target audience insights (demographics, psychographics)
• Current technical/security concerns (e.g., tech debt, vulnerabilities)
• Resource needs (HR, hardware, platforms)
• Business challenges requiring funding

Preparing for Technical Due Diligence

Before meeting with investors, carve out time to build a due diligence deck. Summarize each checklist item and fill in the details from your documentation. Here are some tips to help you prepare:

1. Use visuals – Include images, videos, and diagrams to explain your product and business clearly.
2. Know your facts – Especially if you're in fields like AI, blockchain, machine learning, or crypto.
3. Think onboarding – Present your business like you would to a new team member—clear, concise, and compelling.
4. Update regularly – Keep your deck current as your pitch day approaches.
5. Seek feedback – Ask a trusted advisor with due diligence experience to review your materials.
6. Be prepared – Bring supporting materials to every investor conversation, even informal ones.
7. Be confident and honest – Acknowledge your startup’s limitations and explain how investment can help overcome them.
8. Learn and iterate – Use each experience to refine your pitch and improve your due diligence process.

Technical Due Diligence: What to Expect?

Now that you understand the importance of preparing a pitch and due diligence materials, it’s time to consider the types of investors you may encounter. Each investor brings a unique perspective to the table, and understanding their approach can help you tailor your presentation effectively.

Here are four common types of technical due diligence evaluators:

1. The Mastermind
   This evaluator has deep expertise across all areas of tech startups, M&A, and investment. While their knowledge is impressive, they can be difficult to impress. They often believe they know your business better than you do, so be prepared to present compelling, well-substantiated information.
2. The Bookkeeper
   Focused on budgets and technical metrics, the Bookkeeper excels at identifying ways to improve profitability. However, they may not fully grasp the nuances of your product or market. Clear communication and contextualization are key when engaging with this type.
3. The Prosecutor
   Detail-oriented and meticulous, the Prosecutor zeroes in on overlooked elements and unresolved issues. They won’t move forward until every question is answered and every concern addressed. Be thorough and transparent to earn their trust.
4. The Wildcard
   Often introduced through referrals rather than formal channels, the Wildcard may possess both technical and financial acumen but lack deep startup experience. They can be unpredictable, so it’s important to stay flexible and ready for anything.

Technical due diligence is not just about being evaluated—it’s also an opportunity to assess your potential investors. Pay attention to how they conduct meetings, the questions they ask, and their overall demeanor. Choosing the right investor is critical to your startup’s long-term success.

After the Due Diligence Meeting

The startup world is highly competitive, and investors often evaluate multiple businesses simultaneously. After your meeting, the evaluator will typically compile a detailed report outlining your assets, risks, and overall business value. This report may lead to follow-up discussions or additional technical reviews.

While a positive outcome is ideal, rejection is also a possibility. If your startup doesn’t meet the criteria, ask for detailed feedback. Use it as a learning opportunity to refine your approach and strengthen your technical due diligence for future engagements.
