Built by operators,
not commentators.

OAKFYN was founded by finance operators who have built, scaled, and sold companies. We understand the difference between advisory and execution.

Our work is measured in outcomes: valuation uplift, close days reduced, cash runway extended, and deals closed.

Our Principles

Execution Over Advisory Icon

Execution Over Advisory

We don't deliver slide decks. We deliver outcomes. Our success is measured by your valuation uplift, close days reduced, and deals closed.

Speed & Quality Icon

Speed & Quality

Finance moves fast. We ship weekly improvements, maintain process discipline, and keep projects on track. No endless scoping.

Operator Mindset Icon

Operator Mindset

We've been in your seat. We understand the pressure of board meetings, fundraising timelines, and month-end close. We work as your team, not observers.

Data Standard Icon

Data Standard

Clean data is non-negotiable. We standardize processes, automate where possible, and build systems that scale.
