I believe the top programs are worth it.
On the other hand, in general, an MBA is not valued for 99% of start-up jobs. I never cared about MBAs for any positions I hired for, and in fact, at the margin, viewed an MBA as a negative. MBAs often had higher comp expectations and an exaggerated sense of their management skills, with no direct on-point experience to justify these expectations.
The networks you develop at Stanford or Harvard MBA programs are pretty amazing. And being surrounded by incredible strong peers makes you better and stronger.
I wouldn’t get an MBA in “tech” just to get ahead.
But if you want to do it, if your gut says yes … I think the benefits beyond the degree itself can be material.
