Capitolis

Capitolis is a financial technology company for the capital markets that helps banks and institutional investors optimize how capital is used across their trading portfolios. Its two flagship offerings are a Capital Marketplace that connects banks with origination capabilities to institutional providers of capital, and a Portfolio Optimization service that offsets redundant and offsetting derivatives positions to reduce capital requirements, counterparty exposure, and systemic risk. By combining technology with financial expertise, Capitolis aims to create a safer, more efficient financial system and broaden access to more diversified pools of capital. The platform is delivered as a secure, login-gated web application to regulated financial institutions rather than as a public developer API.

Capitolis is profiled on the APIs.io network. Tagged areas include Company, Financial Services, Capital Markets, FinTech, and Capital Optimization.

Capitolis’ developer surface includes support, engineering blog, and 6 more developer resources.
