On her first day as CFO at Greenphire, Sue Vestri sat in a conference room “learning all of the acronyms” of the clinical trial industry, she tells us. There were “many, many, many,” she recalls, and she listened to the sales team outside her door to understand how the product was positioned and why it mattered.

That willingness to learn from the ground up defines her career. Earlier, a mentor warned her she would stagnate if she stayed in the safety of a large company. “You’ve got to go to grow,” he told her. She left for a 100-employee cloud software firm, a decision that launched a string of growth-company chapters, transactions, and ultimately multiple CFO seats.

At Greenphire, she joined when the company had roughly 72 employees and “very low double digit revenue,” she tells us. Under private equity ownership, it expanded globally, shifted from clinical sites to big pharma customers, and supported the Pfizer clinical trial during COVID. Sue and her CEO conducted “20 or 30 presentations” during a remote exit process, she tells us.

Today, as CFO of CRIO, she describes finance as embedded in the business—not “sitting behind a desk… producing financial statements.” Her filter for AI is deliberate: avoid the “shiny object” and invest in what is “truly transformational,” she explains. Whether evaluating predictive revenue indicators or AI tools, Sue’s throughline remains the same—grow, but with discipline.
