Commercial due diligence is your systematic investigation into whether a startup's business actually works. It examines the company's revenue model, market opportunity, customer acquisition strategy, competitive advantages, and management team's ability to execute. Unlike legal or financial due diligence, which focus on compliance and accounting accuracy, commercial due diligence answers one core question: Is this a business that can realistically scale and deliver returns?
How It Works
Commercial due diligence typically involves reviewing the startup's business plan, financial projections, and market research. You'll analyze customer interviews, competitive positioning, unit economics (cost to acquire a customer versus lifetime value), and go-to-market strategy. This might include speaking directly with potential customers, visiting the company's operations, and evaluating whether the founding team has relevant experience in the target market. The goal is to validate—or challenge—the assumptions built into the company's growth projections.
Why It Matters for Investors
Angel investors often invest in companies with limited operating history and unproven business models. Commercial due diligence reduces risk by separating hype from reality. A startup might have brilliant technology or a charismatic founder, but if the addressable market is small or customer acquisition costs are unsustainably high, the investment won't generate returns. This analysis directly influences your valuation, term sheet structure, and decision to proceed. It's the difference between betting on a team and betting on a business.
Example
You're considering a $250K investment in a B2B SaaS company selling HR software to mid-market companies. During commercial due diligence, you discover the founding team has never sold enterprise software before, their customer acquisition cost is $15,000 but average customer lifetime value is only $18,000, and their target market is dominated by entrenched competitors with superior feature sets. These findings might lead you to pass on the deal—or to negotiate a lower valuation and require hiring an experienced VP of Sales before deploying additional capital.
