CFO THOUGHT LEADER

What does it take for a CFO to restore credibility?
Every finance leader eventually encounters a defining moment when confidence has been shaken—whether by slowing growth, a financial crisis, or years of eroding investor trust. In those moments, success depends on more than financial expertise. It requires disciplined execution, transparent leadership, and the ability to deliver on commitments when every decision is under scrutiny.
In this special compilation episode of CFO Thought Leader, we revisit three conversations that reveal how credibility is earned—and, when necessary, rebuilt.
Aidan Viggiano, CFO of Twilio, reflects on stepping into the role during a period of sweeping change. With growth slowing and difficult decisions ahead, she shares why rebuilding confidence began with one simple principle: do what you said you would do.
Eric Brown, now CFO and COO of Cohesity, takes us back to the near-existential crisis at MicroStrategy, where he and the leadership team were forced to stabilize the business, make painful decisions, and lead through extraordinary uncertainty. His story underscores the critical partnership between a CEO and CFO when an organization's future is on the line.
Finally, Paul Lundstrom, now CFO of Copeland, looks back on his tenure at Flex and earlier leadership at Aerojet Rocketdyne, explaining how stronger financial controls, operational discipline, and consistent execution can gradually restore investor confidence and reshape how the market values a company.
Together, these conversations form The Credibility Playbook—a practical look at how exceptional CFOs navigate some of the most challenging moments in corporate leadership and emerge with something every organization depends on: trust.

Mark Khavkin often finds his best ideas somewhere near the Golden Gate Bridge.
The Rula CFO tells us that he bikes from San Francisco across the bridge and into Marin County—not to compete, but to clear his mind, enjoy the view, and stop for a latte in Sausalito. “A lot of times great ideas come somewhere just before or after the bridge,” Khavkin says.
That preference for space and perspective also appears in how he leads. Compared with a decade ago, Khavkin says that he has become more comfortable trusting people to reach the right result, even when their path differs from the one he might have chosen. Rather than intervening with detailed instructions, he now tries to provide context. “I’m less prescriptive than I was ten years ago,” he tells us.
The shift does not mean avoiding hard decisions. At Rula, Khavkin says that new investments require clearly defined checkpoints and agreement—made in advance—about when the company will increase its commitment or stop an initiative. Once teams, careers, and expectations form around an experiment, he explains, ending it becomes difficult at a human level.
The same discipline shapes his view of AI. Khavkin cautions finance leaders against evaluating the technology primarily through cost savings. According to Khavkin, the greater opportunity is enabling people to perform higher-level work, make decisions faster, and access more organizational context.
For Khavkin, leadership is not about directing every turn. It is about creating the conditions for others to navigate—then knowing when to provide context, when to challenge assumptions, and when to let the road produce the answer.

John Kinzer still remembers sitting in a closed meeting at MCI, presenting revenue results, when something unexpected caught his attention. It wasn’t the numbers he was reporting—it was the questions coming from the FP&A team. Listening to their discussion, he realized, “I also want to see that side of it,” Kinzer tells us. That moment led him from revenue reporting into business planning, where a manager helped shape the analytical skills that would define his career.
Looking back, Kinzer tells us those early experiences proved invaluable. Long-distance telephone plans behaved much like today’s subscription businesses, exposing him to churn analysis, lifetime value, customer acquisition costs, and cohort analysis long before SaaS became commonplace.
Equally important was another lesson from a mentor: always look 18 to 24 months ahead. If you’re no longer learning, growing, or able to see your next opportunity, it’s time to start thinking about what’s next, Kinzer tells us. That advice influenced several career decisions, including his move into the dot-com world, where he participated in his first IPO by helping write an S-1 and develop the company’s long-term financial model.
The same long-term mindset later shaped an even more difficult decision. After being passed over for his first CFO opportunity, Kinzer tells us he resisted the urge to react emotionally. Instead, he focused on developing new skills, particularly investor relations, believing the experience would prepare him for the future whether the opportunity came internally or elsewhere.
For Kinzer, career progression has never been about chasing titles. It’s been about continually putting himself in positions where learning comes first—and trusting that leadership opportunities eventually follow.

When Shane Hostetter arrived at Chemours in 2024, he stepped into a company facing liquidity challenges while also pursuing important long-term growth opportunities. His goal was not to replace decades of institutional knowledge but to complement it. Chemours CEO Denise Dignam brought nearly forty years of experience with DuPont and Chemours, while Hostetter brought an external perspective. Combining those viewpoints, he tells us, helped create “the best of both worlds.”
That approach reflects much of Hostetter’s broader leadership philosophy. Rather than viewing finance solely through the lens of reporting, he focuses on building a stronger foundation for future growth through disciplined capital allocation and balance sheet management.
Hostetter tells us the company developed a three-year strategy designed to strengthen Chemours over both the near and long term. Portfolio optimization became one important pillar, including shutting down selected production lines and divesting non-core assets to improve cash flow. Underlying every decision, he tells us, was a disciplined capital allocation strategy intended to improve financial flexibility.
At the same time, Hostetter has become an advocate for helping others better understand what Chemours actually does. Although many people still associate the company with its legacy DuPont products, he explains that Chemours today serves critical industrial markets ranging from next-generation refrigerants to semiconductor manufacturing, AI infrastructure, electric vehicles, and advanced cooling technologies.
Looking ahead, Hostetter’s emphasis remains consistent: strengthen the balance sheet, allocate capital thoughtfully, and position the company to create sustainable long-term value. For him, finance is ultimately about creating the platform that allows strategy to succeed.

Three accomplished CFOs. Three candid conversations. One revealing look at how finance leaders think about acquisitions before the headlines ever appear.
In this special CFO Thought Leader edition, we revisit conversations with Jonathan Carr, former CFO of Armis, James Redfern, CFO of Reltio, and Toby Driver, CFO of IdeaGen. Each discusses acquisitions from a different vantage point—planning, integration, organizational readiness, and the people challenges that ultimately determine whether a transaction creates lasting value.
What makes these discussions especially compelling is their timing. Carr and Redfern shared their perspectives months before their companies were acquired. ServiceNow completed its acquisition of Armis in April 2026, while SAP completed its acquisition of Reltio in May 2026. Their remarks offer an unfiltered look at how experienced CFOs approached M&A before those transactions became public realities.
Driver complements those perspectives by explaining why successful acquisitions depend on disciplined integration, thoughtful execution, and finance leaders who understand that value is created long after the purchase agreement is signed.
Together, these conversations reveal that successful M&A extends well beyond valuation models and deal negotiations. It requires aligning people, integrating operations, managing risk, and establishing clear decision-making processes across the organization. Whether discussing integration playbooks, organizational change, or strategic planning, each CFO highlights a different dimension of the finance leader's role in helping acquisitions achieve their intended objectives.
For finance leaders navigating growth, transformation, or acquisition activity, these three conversations provide a timely look at the strategic thinking that often precedes—and helps shape—successful deals.
