The risk of customer concentration is that a single large customer cutting orders or switching suppliers creates significant revenue volatility. Digitalization itself won't directly find new customers for you, but it enables you to "actively test the market at low cost"—moving from a passive model of waiting for orders through trade shows and relationships to an active rhythm of testing new products or markets with small-scale experiments. The concrete approach is to first systematize your existing transaction data, identify which products have growth potential in which markets, then use an online platform to run small-scale tests and observe inquiry response patterns. This process requires accumulating data over time before trends emerge, so the earlier you build a data habit, the sooner you'll have evidence for decisions. Customer diversification then becomes a reality rather than just talk.
