- AppNexus, an ad tech firm building a mobile ad infrastructure, has hired former 24/7 Media CEO John Hsu as its new chief financial officer.
- Hsu was CEO at 24/7 Media when it was a publicly traded company and helped sell the firm to WPP for $650 million.
- Hsu's hiring hints that AppNexus is building out its leadership in anticipation of going public.
AppNexus mobile business is 15 times larger since July, and though the firm hasn't released revenue numbers, that could mean big bucks for the company. AppNexus hasn't made any definitive moves toward an IPO yet, but a hire like John Hsu is a step in the right direction.
