Brian Kerrigan

Founder & Managing Partner of Excelerating AI & Excelerating Business Growth | AI-Powered Tax Strategy Expert | Attorney | Business Value Creation & M&A Advisor | Former Ernst & Young Tax Professional

Brian Kerrigan is an accomplished attorney, tax strategist, business growth advisor, and AI innovator with over 30 years of experience helping accounting firms and privately held businesses improve financial performance, reduce tax liabilities, and maximize long-term enterprise value. As the Founder and Managing Partner of Excelerating AI and Excelerating Business Growth, Brian specializes in combining advanced tax planning, artificial intelligence, business strategy, and professional services innovation to create measurable financial value for businesses and their advisors.

Brian began his career at Ernst & Young, where he spent seven years developing expertise in taxation and financial advisory services. Recognizing the importance of integrating legal, accounting, and business strategy, he pursued a law degree while working, expanding his ability to advise clients across multiple dimensions of business ownership and financial decision-making.

Throughout his career, Brian has spent much of his time working within accounting firms, gaining firsthand insight into the operational and financial challenges facing CPAs and their clients. As an attorney and former licensed CPA whose CPA license is currently inactive, he brings a multidisciplinary perspective to tax planning, business advisory services, corporate transactions, and wealth preservation.

Brian believes one of the greatest opportunities in accounting is helping more business owners access proactive, year-round tax mitigation strategies. While many firms possess the expertise to identify meaningful tax savings, traditional service models often limit comprehensive planning to a relatively small group of clients because of the time, research, and partner involvement required.

Through Excelerating AI, Brian has developed an innovative AI-powered tax operating system designed specifically for accounting firms with approximately 11 to 50 employees. The system enables firms to deliver standardized, proactive tax planning services across the entire business ownership lifecycle, from company formation and ongoing operations to business succession, mergers and acquisitions, and the eventual transfer of personal wealth.

His approach uses artificial intelligence to streamline information gathering, tax issue identification, legal and financial research, scenario modeling, and planning documentation. By automating time-intensive analytical and administrative activities, Brian helps accounting professionals focus their expertise on strategic judgment, client relationships, and delivering high-value advisory services.

Rather than replacing accountants or attorneys, Brian's technology is designed to amplify professional expertise, enabling firms to serve more clients consistently while improving the economics of their advisory practices. His vision is to make sophisticated tax planning more accessible to business owners who might otherwise receive primarily compliance-focused services.

Brian recognizes that effective tax mitigation can create value far beyond reducing annual tax payments. Capital preserved through strategic planning can be reinvested into operations, used to fund growth, reduce borrowing requirements, strengthen financial resilience, and increase the wealth business owners retain throughout their careers.

Through Excelerating Business Growth, Brian also advises privately held companies preparing for ownership transitions and potential exits. His work focuses on helping founders increase sales, operating margins, profitability, and valuation multiples while strategically managing annual taxes and the tax implications of major business transactions.

He works particularly with owners planning to sell or transition their businesses within the next three to seven years, helping them develop coordinated growth, value creation, succession, and tax strategies designed to improve financial outcomes.

Brian's expertise spans AI-powered professional services, proactive tax mitigation, accounting firm economics, business valuation, enterprise value creation, mergers and acquisitions, succession planning, and strategic financial optimization. His approach connects the operational capabilities of accounting firms with the broader financial objectives of the business owners they serve.

A key element of Brian's philosophy is that technology should make valuable professional advice more accessible, repeatable, and economically sustainable. He believes the greatest opportunity for AI in accounting is not simply reducing the time required to complete existing work, but enabling firms to deliver important advisory services that were previously too expensive or difficult to scale.

By combining decades of legal, tax, and accounting experience with modern AI capabilities, Brian helps firms rethink how they deliver value, expand client relationships, and create new recurring advisory revenue opportunities.

His mission is simple: Help accounting firms use AI to deliver proactive, year-round tax mitigation at scale while helping business owners preserve more capital, grow enterprise value, and maximize the wealth they retain throughout the business ownership lifecycle.

Based in Colchester, Connecticut, Brian works with CPA firms, accounting firm partners, business owners, CEOs, entrepreneurs, financial advisors, and professional services organizations seeking to modernize tax advisory services, improve firm profitability, expand recurring revenue, reduce tax liabilities, and create more valuable businesses.

Through Excelerating AI and Excelerating Business Growth, Brian continues to develop practical AI-enabled operating systems and advisory strategies that connect technology innovation with professional expertise, helping accounting firms serve more clients while creating lasting financial value.
