The title I wanted to use: "In conclusion, serial entrepreneurs do not appear to be more successful than one-time entrepreneurs and even worse they even seem to perform less and less well with time." The sentence after says, "It should be noticed however that they seem to perform well in the second venture and then the performance degrade with the third venture."
The author seems to define success as market cap.
It would be interesting to see a binary "still around after x years" comparison for single vs serial-founded companies.
