Greater Good Tech’s mission is to deliver transformative B2B and B2G products and services that improve humanity.

Our solutions transform lives and communities with better student outcomes, better patient outcomes, and reduced environmental impact all while improving fiscal efficiency.

Greater Good Tech donates a portion of all proceeds, both financial and in-kind, to 501(c)(3) education and cancer related non-profits.


You've got problems, we've got solutions. One of the greatest issues slowing advancements today is connecting the problem solvers (inventors and entrepreneurs) with those who have the problems (business, government, people). With decades of experience, our founders are accelerating change by bringing together impactful solutions under one umbrella.

Company History:

From 3D Merchant Services and ESG Safe to Greater Good Tech.


Greater Good Tech is the evolution of 3D Merchant Services LLC, established in Broward County, Fl in 2007.  Following partial acquisition of technology and merchant services clients by CenPOS (related to 2019 US Bank acquisition), ESG Safe was created to expand services. Fast forward, Christine and Melissa teamed up to bring together past and new products, building a SaaS and global impact technology company. Reflecting the expansion and global focus, we're rebranding as Greater Good Tech.

Greater Good Tech offers SaaS technologies, and physical products, that solve long-standing problems, improving humanity, environment, and security, often reducing operational and human capital expenses.
