Liftoff is a performance-based mobile app marketing and retargeting platform, using post-install user data to run true cost-per-action user acquisition and re-engagement campaigns. Traditionally, marketers pay for each click or app download when devising a mobile ad campaign, regardless of whether new customers spend money in the app. Liftoff changes this model by only requiring marketers to pay for advertising when a person completes an action or spends money in an app. Powered by machine learning and lookalike targeting, Liftoff's campaigns drive actions beyond the install, securing only the most engaged users for its customers. Mark Ellis, CEO, and co-founder of Liftoff joins me on the Tech Talks Daily Podcast. Mark has made community and culture a core tenet of Liftoff's work, eschewing the toxicity that's rampant in fast-growing Silicon Valley businesses and aiming for impact beyond revenue alone. This approach has been integral to building Liftoff's global, high-performance mobile app marketing platform that's attracted customers like CBS Sports, Amwell, Lifelock, acorns, and many others. The last three years served as another great stretch for Liftoff as the company had explosive growth with over 400% increase in revenue from 2017-2020. With Mark's leadership, Liftoff cemented itself as an industry leader, creating an alliance of mobile marketers focused on promoting good-business practices in a dynamic sector. This community-first approach has come to define Mark's successful tenure and sets him apart from his peers in the tech-startup world.
