I looked up Ex Populus's financing situation, and the public one was probably in December 2021:
The gaming platform closed the round at an $80 million valuation. The project announced an $8.5 million funding round on Tuesday, part of a push to bring different player revenue models to blockchain games — and a more realistic valuation, which now sits at $80 million.
The company completed this round of financing with participation from Akatsuki Inc, Gerstenbrot Capital, Blockwall Digital Assets, Citizen X, Fisher 8 Capital, Perpetual Protocol, Yolo Ventures, Libra Capital Ventures, 8186 Capital and Sneaky Ventures. Ex Populus also raised a $3 million seed round led by Animoca Brands in October last year.
