The author Tim Nolet shares a November 2019 report for his SaaS company Checkly, detailing its monthly recurring revenue (MRR) of $3458 with an 18.12% growth rate. The churn rate is -6.69%, indicating a decrease in customer losses. The company had 22,941 visitors to its blog post front page and 85 signups, resulting in 15 new customers. The author discusses the costs associated with running Checkly, including AWS and Heroku bills, as well as annually billed costs such as software subscriptions and domain registration. He breaks down the costs into variable and semi-variable/fixed categories, revealing a total cost of $1041.79 per month. The author notes that these costs are not out-of-pocket expenses for him, but rather credits he receives from YCombinator Startup School. He also mentions that some costs, such as freelancing expenses, have been incorrectly accounted for in the past. The report aims to provide a clear understanding of Checkly's cost structure and will be used to inform future business decisions.
