For reference $2mm arr is $40k revenue per person per month. A hypothetical 75% margin means $30k margin per person per month.

Very impressive growth and 100% something you and a couple people could live off of. It is not a moonshot tech company/etc though, so if you’re looking to build something big - these are not lessons you should follow.

Spending money on advertising, hiring 1 salesperson, etc would drive a lot more revenue and enable them to scale. That is likely not their goal. I very much preferred working for companies who were highly profitable and didn’t try to outgrow themselves, compared to the opposite.
