This is great advice (And in particular points out the harrowing tale of careful choices that need to be made in a 'clean slate' business).

This is a hard balance to make. Technical choices influence the kinds of staff you would want working for you but you also need to prolong/balance the interests of said staff from moving onto the next thing. (I'd love to know how businesses do this beyond just more money and share schemes but maybe this kind of thing just needs to be built into the plan)
