About company
Wincent
We are a team of over 150 people, primarily Engineers, Traders and Quants, focused on HFT with ~1% of global crypto trading volume. Being a bit weird, we are self-taught; our founders do not come from any of the big HFTs, chose to have no VCs on cap-table, and made Bratislava the central hub. We value integrity, direct communication, and radical transparency in compensation, bonuses, and trading strategies.
