User Growth

User growth measures how many people adopt a product, how quickly they arrive, and whether they stay. In technology, it is often the clearest signal of whether a new idea is catching on or quietly stalling. Revenue, valuations, and competitive positioning frequently follow from it, which is why companies, investors, and developers watch adoption curves so closely.

Why it matters now

The current wave of AI tools has made user growth unusually visible and unusually volatile. Vibe coding platforms let people build software by describing what they want in plain language, and they are drawing in users who have never written code before. AI coding assistants are competing hard for developers, and market share can shift within months as new models and agents launch. Established categories like web browsers show that users will change long-held habits when a credible alternative is easy to adopt.

Growth also has a cost side. As demand for APIs and AI services rises, providers are rethinking free tiers, usage limits, and pricing. These decisions can speed up adoption or push users toward competitors.
