Does this approach scale as users/funding change? I guess I am trying to find out if I can get into something like this (startup) having missed the boat in my 20's. Assuming you have the technical chops but slightly unreasonable demands on you in terms of family time and availability.
Everyone's situation is different. We notice that we are significantly more efficient with whatever time we have available. We get back to work as soon as the kids are asleep for example.
Congrats to the courageous - and experienced! - startup founders with kids and supporting wives - I wish them great success.
Thank you for your well wishes. It's definitely not for the faint of heart! :)
