So , Growing Company , when do I need to come in? Before the A round? When you are planning your new big booth ? When you are about to recruit the US Sales Team?
Here's a rough and ready guide for 3 important stages and the minimum you need to do:
Pre Round A - Work out your Story, Messaging, and Investor Pitch
Post Round A - Leadership Team Speaking Coaching, prepare your team for Trade Shows
Growth Phase - Sales Team Sessions, Service Teams
All of this depends on you overall strategy but at any stage a couple of hours work will make all the difference.
