Could someone explain why [a company in San Francisco] needs to raise funding?What's your guesstimate of how many engineers it takes to run the company? Multiply that by $200k [+]. Quintuple [++] the result. Divide by your guesstimate of their margin. That's the sales number you need to not raise funding.
This math is brutal. You can build a very nice product that a lot of people like and still get run over by it.
[+] Total cash cost to the company (salary, benefits, taxes, etc). This corresponds to an offer of approximately $140k~$160k to the engineer.
[+] Judgement call required here; software startups generally spend 20%~35% or so on engineering. The other big bucks that are not COGS are marketing, sales, and G&A ("everything else that isn't COGS").
