Arca

Arca (Arca Financial, Inc.) is an AI-native wealth management company founded by former Plaid product leader Rron Rexha and headquartered in New York. It pairs human financial advisors with a fully integrated, agentic platform in which AI agents are the primary operational users: monitoring emails, calls, documents, market data, and news, coordinating with one another, generating dynamic user interfaces, and executing multi-step advisory workflows so advisors can focus on client relationships. Arca is an SEC-registered investment adviser managing over $1 billion in client assets, and raised $64M across a seed round (led by Venrock) and a Series A (led by General Catalyst, with Index Ventures and Venrock). It has no public developer API surface at this time; this profile captures its public identity and security posture.

Arca is profiled on the APIs.io network. Tagged areas include Company, Ai Ml, Fintech, Financial Services, and Wealth Management.
