I would like to outline the inception of DEF. First and foremost, DEF is envisioned as an ark for talent. We assemble ambitious individuals to undertake highly complex and profitable projects.
Our team at DEF consists of competent and principled professionals who joined us based on their belief in our values. During the project’s initial phase, we lacked the resources to offer salaries, but this was inconsequential as the determination of passionate individuals is unstoppable.
We are now seeking professional investors who recognize the substantial potential of this venture. We offer not only profit sharing but also our expertise.
Investing in DEF means growing with us, gaining access to exclusive reports, market analysis, and advanced technologies. In return, we pledge to transform the EdTech sector fundamentally.
The DEF era has just begun!
