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.

Regulatory Posture applies to this provider. Its tags matched the Securities & Market Data regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
