I like to use benchmarks of other SaaS companies to find the low hanging fruit. I look at which of my metrics are the lowest compared to the benchmarks and assume they'll be the easiest to improve.
But benchmarks are hard to come by. Participate in this survey and I will publish the results when I get a reasonable number of responses.
Only SaaS companies, please!
