Respectfully (I don't know you): this is bullshit. The terms are set this way because that's what the market will bear in this specific instance. The idea that the terms of VC deals are structured to align the incentives of founders with VCs is a negotiating tactic and little more.

Misaligned incentives might keep you from taking 6 figures off the table in an A round, but anybody who tells you that they're deliberately calibrating your funding to keep you at a below-market salary is feeding you a line.

There are plenty of founders, some of them first-time founders, who make at, near, or better than market salaries. Most of the difference between them and the people whose boards get them to live on ramen is simple negotiating skill.

This isn't to say that there isn't some "hustle quotient" to be extracted from underpaying founders. Just that it isn't dispositive.
