What kind of developers are you able to hire for that paltry sum?
In SF -- We spend $30k/month on salary/benefits/taxes for 4 people (not including rent and other expenses), and even then we're paying below market rate. Our other expenses, including rent, add up to $4k, and we try to sock away at least another $10-15k every month.
Of course, this also isn't a "burn" rate. We've worked hard to build a business the old-fashioned way -- by making money with which to pay ourselves.
Office space is $1,700 - this is up in Vancouver, BC. Again, a bombed-out economy lends itself to finding deals.
I cannot go into the level of developers, but I can say some are presenters at tech conferences, attend the tech conferences, and have built startups before. Again, we manage costs by bringing on people at the right time, for the right amount of time.
