I have also worked on creating a mini version of CE's logo. The image below is a collection of some of my ideations.

Design 1b is the one that got the most attention. It combines:
an image of a globe (international incubatees),
a power plant (a place where they learn),
two keys (two founders of a high-impact charity that went through CE's incubation program).
The mark also combines the initials "С" and "E", having them bound together. This allows the logo to become a pattern in future designs.
