We make advertising better for everyone

Jun Group has built a world where consumers are in control of their advertising, and brands can reach them directly.

Jun Group is a technology company powering media campaigns for the best-known brands, agencies, and publishers. We’re an industry pioneer with nearly 20 years of experience building mobile-first advertising products that deliver real results.


Openness and honesty is at the core of everything we do — from how we interact behind-the-scenes to how our ads show up in the wild. We were founded on the principles of truth and transparency, which will always be our guiding philosophy.

Culture and values

Jun Group supports the boldest ideas with the resources needed to make them happen. We welcome non-traditional career paths and believe in building a team with the right people as opposed to the right combination of keywords.

Foster trust through transparency

Honesty goes beyond how we build our products or show up in the market. We proactively present ways to progress, no matter how great our performance, because trust is not just earned but nurtured through an unwavering commitment to our clients.

Uplift from the top down

Striving to build a community of fulfillment means we have each other's backs. We hold each other accountable, own our individual pieces of the greater puzzle, and come together to reach common goals.

Tenacious commitment powered by ambition

It takes more than a unique solution to outperform the competition. We're unyielding in our search for optimized efficiency. Our determined attitude and drive to operate at a higher level power our iterative approach to execution. 

Innovation ignited by curiosity

Curiosity paves the way for opportunity. Every line of code written and every data point dissected provides necessary insights to evolve our technology. If we’re not satisfied with an existing solution, we’ll build it better.
