Could funded startup founders work normal hours?

I am looking to raise our first round of capital from angels. My question might seem like I'm not fully invested in my startup, but I am. With a family at home, my days of working 80+ hours a week are long over.

At the moment my co-founder and I work a regular 9-5 at our startup and have build an initial version. We have been reaching out to potential customers and have been able to get a few on the paid plans.

If we raise money, would investors be concerned if the founders work a normal 40hrs/week on their startup?

Working 40 hours a week is sutainable over the long haul. (And growing a startup is a long haul!) It's far more important that you are using that time wisely. Your performance drops of quite a but as you work more hours.

Yes.

If I were an investor I'd be far more interested in:

1. Does this person have Intellectual Humility?
2. Do they use their time wisely ? (spending your first 15-30m /day thinking about goals?
3. Get away from work to let their brain rest?
4. Smart and get things done?
5. Have they demonstrated real traction? (sustained user engagement, happy customers, etc.)

You don't need to work more than 40 hours to accomplish any of this.
