Funny table, but does not showing anything about the success of those businesses or the VCes. As far as this table shows, each of these companies may have been a total failure, which I am sure is not true.
There should be columns like "profits", "revenue", "median profits", "number of profitable companies". Such type of columns will show how successful are both the companies and the accelerators.
Also the "average lifespan" and "number of companies still operating" could be other interesting metrics that provide an insight on how sustainable are those companies.
Founder of Seed-DB here. I'd love to get numbers on revenue, profits, etc. but it's essentially impossible to do this for private companies. Even average lifespan is difficult because death is often not a single day, but a slow transition.
