About Us

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.

Let Us Help:

Dear Friend,

I think I have a good sense why you’re here.

You’re frustrated with how much you’re paying in taxes every year. And you suspect it doesn’t have to be this high.

Could you have gotten more tax savings if someone had been paying attention earlier in the year instead of after the fact? The answer is yes.

But… without a proactive strategy, you’ve got a slow leak in the pipe.

You don’t notice it day-to-day, but by the time you sit down to file your taxes, you’re standing in a puddle of “what could have been.”

Taxes get handled once a year based on decisions made months ago. By filing time, most of the options for tax savings are gone.

Our firm works with people who are tired of guessing at tax-saving strategies. Acting as your tax planning strategist, our job is to look ahead for opportunities and help you avoid paying more than you need to. So you never have to wonder whether you missed out on tax savings.

Talk again soon,

Pierre Chayeb, CPA, MBA, Certified Tax Coach
