    Due Diligence

    The comprehensive investigation and analysis an investor conducts on a startup before finalizing an investment, covering financials, legal standing, technology, market position, and team background.

    Due diligence is the formal process through which investors verify every material claim a startup has made and assess risks before wiring capital. It occurs after a term sheet is signed and typically takes 2–6 weeks depending on the stage and complexity of the deal.

    Areas of investigation

    A thorough due diligence process covers:

    • Financial due diligence — historical financials, revenue recognition practices, burn rate, bank statements, and tax filings
    • Legal due diligence — corporate formation documents, IP assignments, employment agreements, pending litigation, and regulatory compliance
    • Technical due diligence — code quality, architecture scalability, security practices, and technical debt assessment
    • Commercial due diligence — customer interviews, churn analysis, pipeline review, and competitive positioning
    • Team due diligence — background checks, reference calls, founder vesting confirmation, and prior exit history

    What investors actually look for

    At the seed stage, due diligence is lighter — investors focus on founder background, cap table cleanliness, IP ownership, and basic financial projections. By Series A, investors dig into unit economics, cohort retention curves, customer references, and detailed financial models.

    Common deal-killers

    Issues that frequently derail deals during diligence:

    • IP not properly assigned to the company (still owned by founders personally or a prior employer)
    • Undisclosed co-founders or equity disputes
    • Material customer concentration — one client accounting for >40% of revenue
    • Outstanding litigation that wasn't disclosed
    • Misrepresented metrics — inflated ARR, counting non-recurring revenue as recurring

    How to prepare

    Smart founders maintain a standing data room with all key documents organized and current. In 2026, tools like Notion, DocSend, and dedicated virtual data rooms make this straightforward. Having clean documentation ready signals professionalism and accelerates the close timeline, which reduces the risk of deal fatigue or market shifts derailing the round.
