At level three, regretted turns should be less than 10% and net revenue retention (NRR) greater than 110%.

Founders should be aware of the signs indicating they might be stuck at level two, such as slow sales cycles, high churn rates, and difficulty in generating demand.

A net dollar retention above 100% indicates that your customer cohorts are growing over time, while below 100% suggests they are shrinking, necessitating more effort to acquire new customers.

If growth slows down significantly after rapid growth, it may indicate challenges at level three.

About 60-70% of companies get stuck at level one or two, leaving only about 30% that reach level three or four.

Signs of being stuck at level one include having customers who wouldn't be disappointed if your product disappeared or if the most important feature varies for each customer.

Companies that fail to understand the quality of their revenue and customer retention often struggle after raising a Series B, leading to potential financial issues.

Net revenue retention measures the percentage of recurring revenue from current users, reflecting how well your company retains and expands its user base.

At level four, you should have a team larger than 100 people and be generating over 25 million in annual recurring revenue (ARR).
