Ostium is an onchain perpetuals exchange built on Arbitrum that lets anyone long or short real-world assets - stocks, commodities, indices, forex and crypto - directly from a self-custodial wallet, with up to 200x leverage and no broker in the middle. Founded by Harvard classmates and former Bridgewater hands Kaledora Kiernan-Linn and Marco Antonio Ribeiro, Ostium uses synthetic perpetuals and a custom oracle system to bring traditional markets onchain. It has processed tens of billions in cumulative trading volume and raised $27.8M total, including a $20M Series A co-led by General Catalyst and Jump Crypto in December 2025.
Kaiko is a global provider of cryptocurrency and digital asset market data, analytics, indices, and surveillance built for institutions. Founded in Paris in 2014 and led by CEO Ambre Soubiran since 2016, the company turns raw data from 200+ exchanges, 20+ blockchains, and 20,000+ digital assets into clean, regulated, institutional-grade feeds used by banks, asset managers, exchanges, and regulators. After acquiring Amberdata in June 2026, Kaiko positions itself as the only independent, globally regulated data and analytics company spanning crypto and tokenized assets.
Ambre Soubiran is the CEO and chairman of Kaiko, the independent provider of institutional-grade, regulatory-compliant cryptocurrency market data and indices. After a decade structuring equity derivatives at HSBC in London and Paris, she walked away from traditional finance in 2016 to buy control of Kaiko - then a bright idea with no revenue and no staff - and built it into a global data business with roughly 130 people across New York, London, Paris and Singapore. She has raised over $80M and positions Kaiko as the trusted, neutral source of truth for crypto markets used by exchanges, asset managers and regulators.
