PRODUCT–FOUNDER FIT

Kaledora (ex-Bridgewater, Harvard) has a macro/trading background and has been publicly driving the thesis of ‘perpification’ (perps-first approach to RWAs). Ostium positions itself as crypto’s macro trading app, aligning her macro focus with an onchain product that lists TradFi assets as synthetic perps with a custom oracle stack.
