My Take

David Filo is the co-founder people forget to name first, and that quiet anonymity is exactly what fascinates me about him. While the public face of Yahoo got the spotlight, Filo was the one writing the C code that actually made early Yahoo run, his Filo Server Program quietly serving those dynamic pages. To me he represents a rare kind of tech wealth: the builder who would rather perfect the machinery than perform on stage. A Wisconsin-born engineer who became a billionaire without ever chasing fame is, frankly, my favorite type of founder.
