our plug-and-play pensionTech to instantly offer an integrated social protection solution to
their clients, members and employees without any new investments in IT or capacity
enhancement.
We’ve recently completed our first equity fundraise to enhance our engineering, business
and delivery capacity and embark on the next stage of pinBox pensionTech development
and expansion. By 2025, we aim to enable and assist 100 million excluded individuals to
start saving for their old age in a secure, affordable and well-regulated environment.
