AdsNative - <a href="http://adsnative.com/" > - San Francisco, CA
We are building ad-server &amp; suite of tools to fix advertising on mobile.  In short, we are making digital advertising content driven and enjoyable. Like you, we also hate intrusive nature of existing display advertising.
Everyone on the team has strong technical/design background. More info on AngelList - <a href="https://angel.co/adsnative" >
We are hiring (full time)-
* Engineering Lead for Mobile
* Front-end Engineer
Feel free to contact me (my email is in profile) or REDACTED_EMAIL.
[EDIT] Here couple of problems/challenges we are solving -
* Keeping latency less than 150ms while serving millions of ads every second
* Since these ads are content driven, figuring out content virality and doing last mile tracking based on analytics/data mining
There are many such challenges that we are tackling so please feel free to get in touch with us even if it's just out of curiosity for you. We love to talk what we are building and getting feedback from startup/hacker community.
