A key viability metric for consumer subscription apps is achieving 30-40% Day 1 retention. Anything lower suggests a fundamental product-value mismatch, making it mathematically difficult to acquire enough users to build a sustainable active user base.

The 'MQL death cycle' is over. Forward-thinking marketing organizations should align around Net Annual Recurring Revenue (Net ARR) as their ultimate measure of success. This metric, which combines new customer acquisition with retention, forces a focus on the entire customer lifecycle and proves marketing's contribution to sustainable business growth.
Everyone obsesses over Net Revenue Retention (NRR), but Gross Revenue Retention (GRR) is the real indicator of product health. GRR tells you if customers like your product enough to stay, period. A low GRR signals a core problem that expansion revenue in NRR might be masking.
The current AI hype cycle can create misleading top-of-funnel metrics. The only companies that will survive are those demonstrating strong, above-benchmark user and revenue retention. It has become the ultimate litmus test for whether a product provides real, lasting value beyond the initial curiosity.
While individual AI companies see slightly lower retention than SaaS, Stripe's data reveals customers often churn from one provider directly to a competitor, and sometimes switch back. This indicates the problem being solved is highly valued, and the churn reflects a rapidly evolving, competitive market, not a lack of product-market fit for the category itself.
After reaching scale, a product's dormant user base is a massive growth opportunity. Activating these users requires designing specific return experiences, like Duolingo’s proficiency tests, which can be a bigger lever than new user acquisition.
For specialized products, user motivation is more critical than age or location. Focusing on the user's mindset, life stage, and readiness for change (psychographics) can lead to significantly higher engagement and retention than targeting a broad demographic group that may not be ready for the solution.
Because AI products improve so rapidly, it's crucial to proactively bring lapsed users back. A user who tried the product a year ago has no idea how much better it is today. Marketing pushes around major version launches (e.g., v3.0) can create a step-change in weekly active users.
To value high-growth, PLG-driven AI companies, segment the user base. The low-end cohort often has extremely high churn (e.g., 60-80%) and should be mentally modeled as a marketing expense for brand awareness. The company's real value is in the high-end cohorts, which exhibit strong net dollar retention (140%+) and enterprise stickiness.
