Big-4 Rigor. Private Office Discretion.

Quantinuum CPA was founded by Pierre Chayeb, CPA, MBA, to bridge the gap between impersonal "Big-4" accounting firms and standard high-street tax preparers. We provide high-earning professionals and business owners with the sophisticated financial leadership usually reserved for enterprise-level organizations—without the jargon or the hand-offs.

Our perspective is shaped by a decade of experience with world-class organizations including Ernst & Young (EY) and DocuSign. We bring that same level of technical precision and multi-state compliance expertise to private clients who demand total transparency and proactive wealth strategy.

The Quantinuum Advantage:

  • Direct Partner Access: You work exclusively with Pierre. We eliminate the "junior staff" model to ensure total privacy and strategic continuity.

  • MBA-Led Strategy: We move beyond basic tax filing to provide forensic-level reconstruction and proactive 2026 planning.

  • Multilingual Support: We provide comprehensive advisory in Arabic, English, French, and Spanish for a diverse global clientele.

Pricing Philosophy

  • Clear, upfront fees based on your needs — no hidden hours.

  • Flat-rate projects or monthly plans for predictable budgeting.

  • Custom quotes for tax and international compliance work.

Simple. Transparent. No surprises.
