0.5% at an early stage with below market compensation, no refreshers with future rounds, negligible comp increase with future rounds, and below-market salary is indeed a scam. A lot of startups are happy to operate this way.
On the other hand, getting 0.5% equity in addition to market rate salary (or adjusted to market rate as soon as funding comes in) with refreshers on each raise to offset dilution and reasonable work life balance can be a very good deal.
I’ve worked for both types of startups. The first type quickly loses their best talent as they figure out they’re getting the short end of the stick. The second type can build a happy founding engineering team that grows with the company and wants to stay for the long term.
Fortunately, the internet has made it harder for companies to get away with the bad deal, below market rate, terrible WLB arrangement that was so common at startups a decade ago. Some people still get trapped by bad deals. Usually when you look at those companies giving bad deals it’s a small group of older founders managing a group of early 20s college grads who don’t yet know better.
