That’s the math that David Cummings wrote about in his post of November 23rd. It is quite simple. If you have $1m of new recurring revenue you are likely looking at a 800k gross margin. Invest half in Marketing and half in hiring two sales people. They will add $1m in new recurring revenue. Rinse and repeat.
I found this interesting article by David Mercer of smepals.com in AllBusiness. He shares 5 lessons he learnt in his entrepreneurial journey and they made a comprehensive list of learnings.
I love to dig through Jason Cohen’s (CTO WP Engine) posts and look what I found – The Fermi estimation for Startup business models. This is an interesting and quick method to figure if your estimates have any legs at all. So what is Fermi’s Problem? Wikipedia says “ The estimation technique is named after physicist Enrico Fermi as he was known for his ability to make good approximate calculations with little or no actual data. Fermi’s problem typically involve making justified guesses about quantities and their variance or lower and upper bounds.”
