I enjoyed the most recent post from Fred of USV about slow capital. He lists some basic tenets of slow capital:
1) doesn’t rush to conclusions and doesn’t expect entrepreneurs to do so either
2) flows into a company based on the company’s needs, not the investor’s needs
3) starts small and grows with the company as it grows
4) has no set timetable for getting liquid: slow capital is patient capital
5) takes the time to understand the company and the people who make it up
