With our current scale, the ongoing monthly costs is equivalent to a small pizza.
Let’s say if we are very fortunate to scale to 25x of where we are now, i believe the monthly costs can be kept to a mid-range dinner with wine, tax, and tips.
What does that mean? There is a benefit of running a tight ship where costs really are not a concern. You can, however, order me a pizza when I am working on the site late at night.
