Most people in most companies will be terrified of someone who seems like an aggressive go-getter. So you'll need to decide what role you're aiming for (sales, marketing, operations?) and then slim everything down to an easy-to-glance-at CV. Keep everything as simple as possible, because most people spend less than 5 seconds on a CV before deciding whether to toss it aside or pay a little more attention. People - all hiring managers and HR drones - are lazy and fearful. So make it easy for them. Talk about how you made your boss successful (or your investors successful). Appeal to their self-interest.

When possible, get as many breakfast and coffee meetings as you can with people in companies you think you'd like to work for. Ask tons of questions, say little about yourself except things that sound like they'll make the people you're talking to more successful and have to work less hard. If you're lucky, one of these people will connect you with someone who needs to fill a position.

The hard truth is that most executives shouldn't be in their jobs, and anyone who looks dynamic looks like a threat. So you need to adjust your approach to reduce your apparent threat level and focus on a single easy-to-understand role that enables someone to slot you in without having to make any mental effort.
