Atlassian, which just IPOd this year, was famously bootstrapped. There are two founders, each with 37.7% [1], so the table is misleading and the should really be 75.4%. Atlassian eventually took funding from Accel, 8 years after its founding.
It is also curious the table rounded Accel's ownership up (12.7 -> 13), but truncated the founders' (37.7 -> 37).
