In this specific case,
1. Very low salary - just enough to afford housing and food.
2. No equity - though the founders promised that I would get some later (yeah, I know I was an idiot).
3. Working 12 hour days including Saturdays.<p>The founders were quite rich and they were of course passionate about their own company because of which they worked even more than me, but I could never feel the same enthusiasm. Interestingly, both of them had worked for larger companies, studied in and traveled to various countries for work which gave me the idea that perhaps it is better to be in a start-up once I have experienced what they have.
