About Kayzen

Kayzen is the future of mobile marketing — building software that allows mobile app developers to connect with their users. 

We are a B2B SaaS platform that allows companies to run mobile programmatic marketing in-house.

Programmatic marketing, put simply, is the process of automating the buying and selling of digital ads in real-time. Programmatic in-housing takes this one step further by allowing advertisers to fully own the technology stack and skills required in this process.

Programmatic in-housing is still in its early days of adoption in the mobile advertising market. This is where we have an impact!
