What valuation are these potential investors giving you? You have to consider missed salary as an investment in the company. Assuming you could have gotten a somewhat similar salary 2 years ago, that means you have a bit under 1 million "invested" in the company. Each year you're putting in another 400k. IMHO, unless you are really about to blow up and start making half a mil in profit a year, take the job. Save your money and in 5-7 years you will have enough to more or less retire. Then start another company and do it without being totally broke.
