"We are building a tiny, ambitious team that works shoulder-to-shoulder 6 days / week."

"Compensation: $130 - $180 / 0.50% - 2.49% Location: NYC"

Why would anyone work six days a week for 0.5%?

At 0.5% ownership, the company needs a $40million valuation for this equity to be worth $200K pre-tax.

If they have more investment rounds and you get diluted to 0.1%, for the equity to be worth $200K the company needs a $200million valuation.

So here's my question: What factors might make these terms appealing, or what might be the reasons someone would consider such a role despite these conditions?

edit: "these conditions" being average/low base, equity with tiny prospects of becoming life-changing money, work 6 days a week
