Customer concentration risk occurs when a large portion of your revenue comes from a small number of clients. This can create financial vulnerability if a key customer reduces business or churns. Understanding this risk is critical in due diligence, strategic planning, and valuation—especially in M&A and investment analysis.
Our platform uses AI and proprietary scoring models to:Identify revenue dependencies across your customer base
-Visualize risk exposure by segment, region, or industry
-Flag accounts that pose high concentration risk
-Recommend diversification strategies
-Our tools integrate seamlessly into diligence workflows, making customer risk profiles fast, objective, and comparable across deals.
The Herfindahl-Hirschman Index (HHI) is a widely recognized measure of market or customer concentration. It is calculated by summing the squares of each customer's share of total revenue, generating a score from 0 to 10,000. Higher scores indicate greater concentration—and greater risk.Use HHI to:
-Assess customer concentration risk during diligence
-Benchmark against peers
-Model the impact of customer loss or diversification
