Andreessen Horowitz (a16z) says the fastest-growing consumer AI companies are breaking through old limits on growth, with retention patterns flipping into positive territory.
In a new analysis, the venture firm frames this shift as a structural break from the old churn-heavy model that constrained consumer software.
The firm argues that AI-driven products are monetizing faster and sticking longer than anything that came before.
The firm says that two drivers are fueling the pattern.
“The fastest growing consumer AI companies are now seeing revenue retention above 100% – what I call the ‘Great Expansion.’ This happens in two ways: 1) consumers spending more as usage-based revenue replaces flat “access” fees, and (2) consumers bringing tools into their workplaces at an unprecedented speed, where they can be expensed and supported with larger budgets.
The difference in trajectory is dramatic. At 50% revenue retention, a company must replace half its base every year just to stay even. At more than 100%, every cohort is expanding – growth compounding on top of growth.”
The firm says under the old model, most consumer subscription companies were considered best in class if they held on to 30–40% of their revenue base after the first year. AI flips that logic, allowing every customer cohort to expand spending over time rather than shrink.
The mechanics come from more flexible billing. Instead of locking users into a flat monthly fee, AI firms are layering subscription tiers with usage-based charges, credit packs, and upgrades. The formula lets revenue rise in line with engagement.
“The most successful consumer AI companies are not relying on a single subscription fee. Instead, they use hybrid models with multiple subscription tiers plus usage-based components. If a user maxes out their included credits, they can buy more or upgrade to a higher plan.”
A second catalyst is the workplace. According to a16z, consumers bring AI tools into offices and expense them, exposing products to larger budgets and less price-sensitive buyers. Andreessen Horowitz describes this bridge from consumer to enterprise as a critical expansion lever.
“Consumers are actively rewarded for bringing AI tools into their workplaces. In some companies, failing to become ‘AI-native’ is now considered unacceptable.”
