Commercial due diligence, explained.

    What is commercial due diligence?

    Commercial due diligence tests whether a target's market, customers, competitors and growth plan support the investment case. It checks market size and direction, customer concentration, competitive position and the plan's assumptions. Reuben AI researches each area, traces every finding to its source and keeps it current through the deal, alongside any advisers engaged.
