Summary
I operate as a fractional finance leader for companies navigating growth, complexity, and transaction activity.
My work sits at the intersection of accounting, finance, and strategy—helping organizations make disciplined decisions while building scalable financial infrastructure.
Areas of focus include financial modeling, scenario planning, buy-side and sell-side diligence support, and post-acquisition integration with consolidated reporting. Additional experience includes ERP implementation, finance function transformation, internal controls, audit readiness, and technical accounting.
EXPERIENCE & ENGAGEMENTS
Recent experience includes supporting a $4B SaaS merger and post-acquisition financial modeling and integration for a $140M+ international medical device manufacturer. Prior M&A leadership roles involved supporting acquisition strategy and integration planning for various organizations.
Experience spans investor-backed and high-growth organizations across SaaS, technology, and medical device sectors.
In 2026, I founded Koretoff Advisory, a business consulting and accounting firm. Through the firm, I provide fractional financial leadership and a range of finance, business valuation, and internal controls services.
I’m typically engaged when:
A company is preparing for or actively navigating a transaction.
Newly acquired entities need to be integrated into financial reporting.
Financial visibility, forecasting, or reporting needs to improve.
Finance functions need structure to support growth or complexity.
Leadership requires a hands-on operator at the Controller or VP Finance level.

Accounting Today
Corporate accountants should be involved with all tech implementations because they are responsible for protecting the organization's financial well-being and maintaining proper internal controls over financial reporting.

ENDORSEMENTS

I had the pleasure of employing Ryan as a Senior Consultant on the Finance Team for close to 18 months. While he was initially slotted to assist in coverage for an employee on leave, he quickly made himself indispensable to our team. He enthusiastically accepted all assignments and went beyond requirements by enhancing and streamlining current processes. He pointed out areas where potential improvements would be beneficial and presented well-thought-out suggestions on how to institute the necessary changes. He consistently embodied the highest level of diligence, perseverance, and professionalism.
In addition to finance assignments, Ryan became a valued member of our ERP implementation team. Our IT leaders commented on his outstanding contributions. He truly played an integral role in our successful implementation. I highly recommend him to any company considering an additional resource to supplement their team.
