Dive Brief: 

• Ad buying technology firm MediaMath has received $73.5 million in Series C funding in addition to increasing its debt by $105 million. 
• MediaMath has been working to move more into mobile as the market continues to shift that direction, and it could potentially use the funds for acquisitions in the space. 
• The money could also be used to float MediaMath's efforts to put off an IPO until the market is stronger for ad tech firms. 

Dive Insight: 

MediaMath has been struggling to make a transition from desktop to mobile, so any this will help propel the firm forward. It will be interesting to see what, if any, acquisitions MediaMath makes in the near future to help build its mobile presence.
