We believe that quality data is essential to helping software companies scale, which is why we make our own internal consolidated metrics available to founders each month. These numbers are aggregated from hundreds of private software companies that RAC reviews across our funds, using only primary sources, validated by our investment team. We exclude companies that are below $2.5 million of ARR.
The August metrics by growth cohort:

The August metrics by Rule of 40 cohort:

To learn more about the Private Software Growth Index and how it was constructed, please see the disclosure at the bottom of this post.
Our observations on the August data:
-
Growth was higher in August compared to the same period last year in every category of our dataset. Median, top quartile, AND bottom quartile growth are all higher than they were in August 2025
-
Gross AND net retention are also higher in our dataset across the board compared to last year (median, top quartile, and bottom quartile)
-
Similarly, median, top quartile, and bottom quartile rule-of-40 have all risen compared to a year ago, and are trending up since last month
-
Burn has ticked up slightly in the slower-growing cohort, which we attribute to increased spending on product/R&D in search of growth (spending on S&M is largely unchanged)
-
To us, one of the most interesting aspects of the AI transition in tech is the widening dispersion in performance between top performing cohorts vs. all others. For example, the delta between the median and the top quartile rule-of-40 in our dataset has grown materially since December 2022 (the first month after ChatGPT was released). The best companies appear to be pulling further away from everyone else
-
In line with this pattern, the percentage of companies in our dataset that exceed “rule of 40” and “rule of 60” has also increased materially since December 2022. Our theory is that AI tooling is likely enhancing what works at great companies, but also amplifying any friction that exists in the less-successful ones, feeding a greater dispersion around the median
