Cfo Thought Leader

Stacy Tumarkin unexpectedly found herself stepping into the CFO seat—twice—earning the moniker “The Accidental CFO.” Early in her career, she worked at a hedge fund, diving headfirst into uncharted responsibilities when a mentor urged her to stretch beyond strict accounting roles. “I was only 26 when I first became CFO,” Tumarkin tells us, recalling how imposter syndrome quickly followed. Despite her misgivings, she soon realized the best way to grow was to embrace discomfort and learn on the fly.A second twist came when she joined Kubecost as Chief of Staff, overseeing everything from support to finance. When the CEO asked her to serve as CFO yet again, she hesitated—still viewing herself as more of a people-first leader. But Tumarkin tells us that ownership of the finance function gave her a strategic seat at the table, allowing her to shape the company’s trajectory while drawing on her passion for operations and culture.

Back in the mid 1990s–when Russ Keefe decided it was time for a career pivot–he got behind the wheel. With a Jeep packed full of his belongings, he drove from Washington, D.C., to San Francisco, father riding shotgun, to explore fresh opportunities in Silicon Valley. He had just completed a stint at the U.S. Securities and Exchange Commission, where he gained a deep respect for transparency and learned the importance of full disclosure.Eager to drive business outcomes, Keefe immersed himself in tech, soon discovering a passion for FP&A and leadership. Early roles exposed him to sales operations, giving him a front-row seat to understand revenue streams and product strategies. “That was when I realized finance is so much more than keeping score—it’s about guiding strategic decisions,” Keefe tells us.Today, as CFO of cybersecurity innovator Corelight, Keefe applies a forward-looking mindset to navigate hypergrowth markets. His background at the SEC informs his ethos of communicating frequently and candidly

It was shortly after Eugene Wong exited the banking world to advance into a senior operations role that he realized the importance of a holistic view. At one meeting, he uncovered a disconnect between product and sales teams that threatened a strategic initiative. By stepping in and aligning priorities, he emerged as a “quarterback,” bridging perspectives and clarifying responsibilities.This revelation set the tone for Wong’s career journey. Originally honing his financial acumen at Silicon Valley Bank, he gained close exposure to startup ecosystems and leveraged finance transactions. Later, he pursued an MBA, joined Goldman Sachs to build on transactional capabilities, and returned to Silicon Valley Bank in a senior role. Ultimately, he stepped into the fast-paced realm of growth-stage companies, seeking to become a true financial operator.Today, Wong serves as CFO of Clara Analytics, where he orchestrates data-driven decision-making and fosters cross-functional collaboration. “You can’t stay behind spreadsh

Four years into his 12-year career chapter at Amazon, Hetu Patel was appointed Finance Director for Prime—a role he credits with opening his eyes to strategic finance. In the days ahead Patel would be handed a milestone assignment, where he worked on a groundbreaking framework attributing the total value of Prime membership to each bundled benefit: video, music, books, and fast shipping. Collaborating with economics and business teams, he quantified how each offering affected purchase behavior and membership renewals, “Patel tells us.” This data-driven approach ultimately informed billions in investment decisions, illustrating how finance could reshape strategy, boost decision-making speed, and deliver transformative impact.Patel’s nearly 12-year tenure at Amazon exposed him to operations, retail category development, and even a general manager role, sharpening his analytical skills and broadening his perspective on enterprise-wide connectivity. “Improving the quality and speed of decision-making is the most

When you think about accounting at growth stage companies, the word "artistry" might not immediately come to mind, but Desene Sterling makes a compelling case for it in this episode of Controllers Classified.

Desene recounts the feeling of being the first in-house accounting hire, navigating "free-for-all" credit card policies and training teams to embrace structure in a way that doesn’t stifle innovation. Her philosophy? Build processes that flex and grow alongside the company, even if that means starting with something imperfect.But it’s not all about debits and credits—relationships take center stage too. Desene explains how building credibility w

CFO Kfir Lippmann began his career at Ernst & Young in Tel Aviv, auditing high-growth tech clients and navigating the intricacies of IPO-bound businesses. The experience gave him a deep understanding of strategic finance early on, Lippmann tells us. Later, he joined Monday.com when it was still a small startup, helping scale the organization through multiple investment rounds and significant secondary transactions. These transactions, which allow employees to sell shares prior to an IPO, can be tricky to manage from a morale standpoint. “It’s about maintaining fairness and long-term vision,” Lippmann tells us.By educating employees about responsible wealth management, Lippmann tellsus he was able to preserve the company’s collaborative culture and harness momentum for broader strategic goals. His approach to finance leadership emphasizes transparency and data-driven decisions across all functions, not simply “being the bad guy,” Lippmann tells us.

It was late 2020 when Michelle Hook ended 17 years of fruitful career-building at Domino’s to accept a CFO appointment at fast casual restaurant chain Portillo’s.  “The two things that I was looking for were to be passionate about a new brand and to feel a culture fit,” recalls Hook, who adds that she had long imagined someday leaving Domino’s to join a smaller company that she could help to grow.“I just didn’t care about going to a bigger company or ‘X,’ ‘Y,’ or ‘Z,’” continues Hook, who tells us that she ultimately took a leap of faith with regard to there being a culture fit at Portillo’s.“I actually never stepped into our headquarters until my first day on the job and had met in person only with the CEO, since this was during COVID times and the rest of the hiring process had been done on Zoom,” comments Hook.Fast-forward 15 months to when the Omicron variant was still grabbing headlines and inflation had begun to rattle the economy—and Hook could not escape the notion that the traditional Portillo’s

Among the learnings that Dev Ahuja has gleaned from his three-decade-long, globe-hopping finance career, perhaps none has delivered a more enduring instruction than that which followed his very first hop.By his own account, after Ahuja had reached the summit of Novartis’s finance executive ranks in India, the drug giant invited him to occupy an office at its Basel, Switzerland, headquarters. Here, Ahuja was promised, he would be able to apply his flourishing financial acumen on a more global scale.  “I thought that I knew what it took—I came with a lot of confidence rather than in a mode of humbleness and wanting to learn,” comments Ahuja, who let us know that his first years at headquarters did not always go as planned.Ahuja reports: “The Swiss don’t mince words."Confronted with his shortcomings, Ahuja set out to get things back on track—beginning with a hefty dose of self-scrutiny.  “I had done a miserable job because I really had not made the effort to build relationships and take the t

monday.com CFO Eliran Glazer highlights three vital priorities for 2025. First, he stresses that long-term efficiency must guide strategy. Instead of focusing solely on near-term investor demands, CFOs must structure financial planning like a marathon—mapping out sustainable growth through transparent scenario planning that accounts for macro uncertainties. Second, Glazer emphasized that CFOs need to become tech experts. With remote and hybrid work creating a surge in disconnected software tools, CFOs must champion integrated systems, unify data, and eliminate costly redundancies. Finally, Glazer underscored the increased need for real-time, data-driven insights. In a volatile market defined by inflation and local pressures, CFOs can no longer rely on static reports. They must deliver on-demand analytics and immediate forecasting to guide decisions around profitability, cost management, and risk.Sustainably grow through scenario planning for evolving macro trendsAlign technology to unify data and reduce cost

Ask any business manager about the “three Ps in business” and they will likely say People, Process, and Product. However, ask any finance team member at Cribl that question, and you’ll likely hear a different answer: Precision, Predictability, and Performance. These are the three Ps that guide CFO Zach Johnson’s data-driven approach to financial leadership.Johnson’s career journey provides the context for this unique framework. At Splunk, he witnessed firsthand how a company could grow from roughly $40 million in revenue and 130 employees to more than $1.5 billion and nearly 2,000 employees, he tells us. During this period, Splunk navigated a complex transition from on-premise software to cloud-based solutions, forcing the team to reevaluate pricing, infrastructure, and market strategies. That experience taught Johnson how to deconstruct challenges into measurable components that teams could understand and act upon.Now, at Cribl, Johnson applies his three Ps to ensure a sustainable, value-driven path forward.

Joanne Cheng’s career had already carried her through multiple successful exits and leadership roles when an unexpected opportunity arose. Having proven her ability to guide companies to liquidity events and beyond, Cheng had established a new benchmark for any next move: she wanted to steer a firm toward an IPO while serving as its CFO. But then along came Jellyfish, a company whose big day in the public markets would likely be years away.At first glance, Jellyfish didn’t fit Cheng’s established criteria for her next CFO position. The company was still small—just about 90 people—and lacked a finance team. Yet there was something about Jellyfish that instantly drew her in. Before she fell for the company, she fell in love with its product. As Cheng puts it, “I’ve needed this product at every company I’ve been at. Measuring R&D impact and efficiency is something I’ve thought about for much of my career.”While the prospect of an IPO was an important consideration, Cheng realized that her passion for Jellyfi

Managing cash flow and ensuring payroll, he says, are unyielding priorities. “If you can’t make payroll, that’s a big, big issue. It destroys trust,” he reflects. While this hands-on responsibility was not unexpected, Lam tells us he's learned to enthusiatically embrace it, finding enjoyment in understanding financial details down to the dollar.Lam’s career began in India, where KPMG had recently opened an office. “I was the third person to join them as an article clerk and the first among them to qualify as a chartered accountant,” he explains.
