The most valuable lesson I had from the companies I ran/run is that both sales and getting investment are both volume plays. If am a technical guy and I used to be that even more than I am now; I thought people who could do sales were deeply magical creatures. But every time we had a 'super sales' (usually co-founder because of the 'super' part), the super wore off and turned into no sales which killed or downsized companies eventually. I only fairly recently found out that it is just a matter of meeting as many people as you can and having as many sales pitches as you can. Investors the same thing, although that depends a bit more on the phase and the business than the sales.
