.capital domains

The .capital domain is a professional extension for the world of money and investment: venture capital and private equity firms, asset managers, investment banks, financial advisors, and real-estate capital groups. The word signals scale and seriousness, so a .capital address reads as credible to investors, partners, and clients. It also suits companies that want to project ambition and financial strength, and it can play on "capital" in the sense of a capital city or a headquarters. Registration is open worldwide with no restrictions. For a firm whose business is deploying or managing money, a .capital domain aligns the web address with the work itself, lending immediate authority to a fund, an advisory practice, or an investment platform in a competitive, trust-driven field.
