Looking At The Real-Time Bidding Numbers With PubMatic’s Goel

SHARE:

PubMatic In MediaweekAdExchanger.com asked PubMatic’s CEO Rajeev Goel about their recent estimate for total RTB (real-time bidding) spend this year and last which he offered in a MediaWeek byline this week.  Goel emphasized that this is an estimate.

RG: Our estimate is based on our own methodology. Here is an overview of how we came up with it:

  1. We took an estimate of revenue made from the DSP’s in 2009, which we gathered as less than $100MM total based on a number of things including conversations we’ve had w/ CEOs, etc.
  2. We expressed $100MM as a percentage of the $15B online ad market – which is .70%, or roughly 2/3 of 1%.
  3. Then, we added the latest players in the space, and looked at how things are ramping up on our side. We see aggressive growth in in 2010… So, 3-5% is our best estimate.

To be clear, this is NOT reflective of the percentage of RTB transactions that PubMatic facilitates.
