Our Story
Mobile Locker's roots in life sciences run deep. Founder Mark Stralka started at Johnson & Johnson 25 years ago as an intern, progressed through their leadership development program, and held roles in Information Security and Enterprise Architecture. At J&J, he built the platform powering 150+ pharmaceutical and consumer products websites for J&J brands worldwide.
In 2007, Mark left J&J to found Kazaam Interactive, a digital agency focused exclusively on life sciences. When the iPad launched in 2010, Mark saw an opportunity to transform how pharmaceutical sales teams engage with healthcare professionals. That year, he developed and launched the first version of Mobile Locker.
The platform's success led to Kazaam's acquisition by inVentiv Health (now Syneos Health) in 2012. Mark stayed through 2015, continuing to evolve Mobile Locker for large pharmaceutical clients. But in 2015, he made the decision to buy the company back to focus on what he did best: building software that sales teams actually love to use.
In 2020, Bob Lempke joined as Chief Commercial Officer, bringing decades of enterprise software sales experience to accelerate Mobile Locker's growth. Together, they've built a team that combines deep pharmaceutical industry knowledge with technical excellence.

I wanted to share with you how helpful today's session was. I cover Mayo Clinic in Rochester. I have struggled to make connections there and have tried to work strategically to get engagement. After seeing how to create the emails lists and attach information, I did just that. I sent out 40 emails to cardiologists. I LOVE that I can see that within minutes several cardiologist have opened the email and have or are reading the new Claims Data.
