Databento
Databento is a licensed market data provider that lets traders, quants, and developers pull live exchange feeds and decades of historical tick data through a single API with a pay-as-you-go model. Founded in 2019 by former quant hedge fund traders, it replaces the slow, expensive, contract-heavy process of buying market data with self-service access across 45+ trading venues and a unified data format.
Kaiko
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.
