How Startups Acquire and Retain Customers

Startups can steadily acquire customers and maintain relationships for the long term without relying on viral growth—the kind of explosive awareness that spreads through word-of-mouth or social sharing. These insights were shared at a session at TechCrunch Disrupt last week. Two founders and one venture capitalist took the stage to discuss how to gather early-stage users and how to retain them.

When startups enter new markets, it is not uncommon for them to seek breakthroughs through 'viral strategies' that spread explosively via social media and word-of-mouth. However, there is now a widespread recognition in the industry that going viral is not reproducible and cannot be engineered intentionally. Instead, there is a view that a painstaking approach—carefully building relationships with specific customer segments and consistently delivering value—leads to a sustainable business foundation in the long term.

TechCrunch Disrupt is a major annual conference for startups and technology, known as a gathering place for entrepreneurs and investors. In this session, the central question was the practical one of 'not just acquiring early fans, but how to retain them.' The founders and investors who spoke drew on their own experiences, presenting perspectives gained from real-world practice rather than mere theory.

At the heart of the session was the idea that 'customer relationships are about quality over quantity.' Early users are a valuable source of feedback that shapes the direction of a product or service, and carefully continuing to listen to their voices leads to product improvement and organic growth through word-of-mouth. It was also shared that creating conditions where acquired customers do not leave is important for reducing the cost of acquiring new customers.

This discussion can be seen as applicable to startups in general, including those in the AI field. As generative AI and SaaS products proliferate, differentiation is becoming harder, and user retention rates are being re-emphasized as a key indicator of business sustainability. The emphasis on the satisfaction and continued usage rates of existing users, rather than viral awareness, is gaining weight from the perspective of investor evaluation as well.

Going forward, when evaluating startups, the focus will need to shift from absolute user numbers and scale of viral spread to questions such as what proportion of customers continue to use the product over time and how deeply rooted the community is. The search for a sustainable growth model to replace virality is becoming a shared challenge across the industry.
