Which part? The 80+ hour a week part, or the wanting people with family part? I think the OP's point was that killing yourself at a startup is a young person's game, and he still wants to hire people more experienced people with families who are looking for ~40 hours. That would unusual in many startups, so I think it is worth mentioning. How would you say it better?

  "Us founders are blitzing 80+ hours a week."

This is where most people with a family would stop reading.

  "If you're young and energetic, come join us."

That is border-line ageist. The rest is a half-hearted apology that won't entice a normal person to want to work in the advertised conditions.
