In light of OpenX and SteelHouse's recent announcements that they had both exceeded $130 million in revenue in 2015, we decided to put together a short list of LA ad tech companies you should know. From industry mainstays to up-and-comers, here are 10 startups changing the digital ad space:


Since 2011 Centerfield has provided their clients with a network of content-rich websites in order to find the perfect platform for their message. They developed a unique ad tech tool that focuses on real time biddable media for their clients. 


Founded in 2012, The Mobile Majority offers an end-to-end mobile advertising platform at a more cost-effective price. The company currently has offices in New York City, San Francisco, Chicago, and Sao Paulo. 


OpenX has received a lot of attention recently as their ad marketplace has helped them exceed $100 million in revenue. The platform works for both publishers and ad buyers to sell and purchase ad space, respectively. 


After tripling their revenue in 2015, SteelHouse is now referred to as the fastest growing company in advertising. The company created a cloud-based marketing platform (called SteelHouse Canvas) to simplify a variety of marketing needs like retargeting and look-alike solutions. 


Founded in 2007, Rubicon Project engineered the Advertising Automation Cloud to help automate the buying and selling of advertising on a global level. The company went public in 2014 and turned their first annual profit in 2015, raising their GAAP revenue98 percent to $249 million.
