Not really, there isn't enough information in the graphs to make that kind of claim. You can say that 45.9% of startups that raise $10m have 1 founder, but unless you know percentage of startups that have 1 founder you don't know anything useful. Maybe 50% of all startups have 1 founder, in which case 1 founder startups are underperforming.
If 99.9% of all startups have 1 founder then the numbers for everything except 1 founder startups look incredible.
