Arca

What Arca does

Arca (legal entity: Arca Wealth, LLC) is an AI-native, fee-only Registered Investment Advisor that delivers comprehensive wealth management to high-net-worth individuals, business owners, and equity compensation recipients. Founded in 2026 by Rron Rexha (formerly a product leader at Plaid), the firm operates a 100% fiduciary model with offices in Bethesda (headquarters), New York, and Portsmouth, and a stated minimum of approximately $500,000 in investable assets. At launch the firm reported over $1 billion in client assets, a footprint that was assembled largely through the Granite Bay Wealth Management seeding relationship and the May 2026 acquisition of Sandbox Financial Partners.

The core offering is an integrated advisory platform spanning financial planning, retirement planning, equity compensation management (RSUs, stock options, ESPP), estate planning, business exit planning, and tax planning, delivered through AI-driven back-office automation that the firm uses to scale advisory capacity without proportional headcount growth. Client assets are custodied at Altruist. Arca is positioned as an "ecosystem" advisor rather than a siloed service provider, and its strategic partnership with Anthropic functions both as a credibility anchor and as a referenceable enterprise relationship.

Revenue is generated through AUM-based advisory fees (percentage of assets under management) supplemented by a stated minimum annual fee and flat-fee arrangements for complex engagements. Distribution is primarily direct-to-client, initiated via a complimentary 30-minute consultation, and supported by a content marketing engine (editorial journal, email newsletters, and SEO-optimized educational content). The firm employs approximately 28 staff across advisory, operations, and product/engineering, with an average advisor tenure of 16+ years and professional credentials including CFP, CIMA, and CFA. Total institutional funding raised to date is $64 million across a $15.5M seed led by Venrock and a $48.5M Series A led by General Catalyst with Index Ventures and Venrock participating.

Broad incumbents

• Schwab Wealth Advisory: Charles Schwab's fee-based advisory service combining dedicated advisors with digital tools for HNW clients. Comparable as a scaled fiduciary wealth management offering competing for the same HNW households Arca targets, but part of a much broader brokerage franchise.
• Fidelity Wealth Services: Fidelity's dedicated wealth management service for HNW clients with comprehensive financial planning. Comparable to Arca's HNW, comprehensive-care model, but embedded in a much larger brokerage and asset-management franchise.
• Vanguard Personal Advisor: Vanguard's hybrid robo-plus-human RIA targeting mass-affluent and HNW investors at low fees. Comparable to Arca in fiduciary, fee-based advisory, but with significantly lower cost positioning and incumbency advantage.

Direct peers

• Betterment: Pioneering robo-advisor and registered investment advisor combining automated portfolios with access to human advisors. Comparable to Arca as a tech-forward RIA serving HNW and mass-affluent households with goal-based planning.
• Empower Personal Dashboard (formerly Personal Capital): Hybrid RIA offering digital tools plus human advisors to HNW clients, with strong emphasis on financial planning and retirement. Directly comparable to Arca's blend of comprehensive planning, fiduciary advice, and a $500K-ish HNW threshold.
• Range: AI-native wealth management platform pairing financial advisors with modern software for HNW clients. Highly comparable to Arca's AI-native, advisor-augmented model and integrated financial planning approach.
• Savvy Wealth: AI-powered platform powering modern RIAs with tech, compliance, and investment infrastructure for HNW clients. Comparable to Arca in using AI to scale advisor productivity and in serving HNW client segments.
• Wealthfront: AI-driven, fee-only RIA offering automated and hybrid advisory services to mass-affluent and HNW clients. Highly comparable to Arca on tech-enabled, fiduciary wealth management, though Wealthfront skews more digital and lower-minimum.
• Farther: Tech-forward RIA serving HNW clients with a blend of human advisors and modern technology. Closely comparable to Arca in targeting HNW households, fee-only fiduciary model, and AI-enabled advisor productivity.

Others

• Altruist: Modern custodian and technology platform built for RIAs. Directly comparable to Arca as the primary custodian for its client assets, and as a tech-forward RIA infrastructure partner, but Altruist serves advisors rather than end HNW clients directly.
