Meet our team of experts.
We set out to solve one of the biggest challenges in the wireless industry — frustratingly slow and costly SIM vendors — by developing a solution we wish we’d had when we were in your shoes.
The RiPSIM™ team is comprised of talented industry veterans, each with decades of wireless experience, who share the common vision that if there is a better, faster and less expensive way to do things, it should be done.
We’ve worked at wireless service providers, device OEMs, and global SIM manufacturers. We have developed custom software solutions, designed new technologies, and commercially launched them all.
We are passionate about changing the status quo and introducing independence and autonomy in a domain that is dominated by rigid companies that try to lock you into their outdated business models.
