Startups: Burn Rates At Different Stages

We spotted this today:

"Building Product Stage - I would strongly recommend keeping the monthly burn below $50k per month at this stage...
Building Usage Stage - I would recommend keeping the monthly burn below $100k per month at this stage ..
Building The Business Stage - I would recommend keeping the burn below $250k per month at this stage.

A good rule of thumb is multiply the number of people on the team by $10k to get the monthly burn. That is not the number you pay an employee. That is the "fully burdended" cost of a person including rent and other related costs"
