Startups have the ability to compete in ways like better equity deals but by and large they still highly prioritize their investor concerns over hiring concerns as reflected in things like liquidation preferences in ISO and stingy equity grants. Most of the founders would rather ride their startup to the grave then re-evaluate the “standard” terms of their equity compensation approaches which each year have become more favorable for VCs and less favorable for employees.
Even though big tech has many problems and things I disagree with, at the end of the day they respect engineers by paying them their value while startup founders prefer to make engineers second class citizens then bemoan their hiring difficulties.
