Gary Boomer
CEO, Boomer Consulting
Has advised large US firms on technology and practice management for decades. Strategic rather than tactical — worth following if you are thinking in five-year horizons.
Most lists of "accounting influencers" are the same twenty-five American names recycled between directory sites that have never read any of them. This one is regional, deliberately short, and says what each person is actually good on.
Updated 2 August 2026 — reviewed annually.
The deepest pool by a distance, and the reason most "global" lists are really US lists. The risk here is not finding people — it is mistaking volume of posting for having something to say.
Listed alphabetically, not ranked — a league table of real people is a fight nobody needs.

CEO, Powerful Accounting
Runs a firm specialising in tax, forensics and fraud, and is refreshingly direct about client boundaries and pricing. Named one of the 25 Most Powerful Women in Accounting.
Accounting technology speaker
Known on the US conference circuit as "Inspector Gadget" for a reason — a reliable early read on which technology is real and which is a demo.
Founder, SMD Consulting
Advocates rethinking the shape of a practice rather than optimising the existing one. Good counterweight if your improvement plans are all incremental.
AICPA-CIMA; former CEO, Maryland Association of CPAs
Once ranked the second most influential person in the profession and inducted into the Thought Leaders Hall of Fame. The best single source on where the profession as an institution is heading.
Host, The Accounting Podcast
The most consistent independent commentator on the profession, and willing to be critical of the vendors and institutions everyone else is careful around. Named in Accounting Today’s Top 100 Most Influential People.
Founder, IntrapriseTechKnowlogies
Bridges advisory, technology and governance, and is unusually rigorous on risk and internal control at a time when most tech commentary skips both.
Founder, Realize
Builds in public and shows the actual workflow rather than the finished slide. Realize is one of the few genuinely high-signal communities for firm leaders.
Co-host, The Accounting Podcast
Came up through the app ecosystem rather than practice, which makes him the sharper of the two hosts on where a vendor story does not add up.
"The Radical CPA"; co-founder, XcelLabs
Has spent a decade arguing the firm model itself is the problem, not the technology bolted onto it. You do not have to agree — but you should know the argument.
Founder, The Thoughtful Advisor
Focused on the thing most technically excellent accountants are worst at — explaining financial information to a client in a way that changes what they do next.
Co-founder, ConvergenceCoaching
Built the first successful CPA firm influencer programme and has advised firm leaders on succession and people strategy for years. Strongest on the leadership problems firms avoid.
