20VC: From $6.2BN Market Cap to $2.8BN: What Is Not Translating About Navan's Public Story | Are Any Public Company CEOs Actually Happy? | Why Navan Built It's Own Customer Service AI and What it Could Mean For Customer Service AI with Ariel Cohen

Public company CEOs aren't supposed to admit they hate the stock price obsession. Ariel Cohen just did.

The Navan CEO's company went public after 11 years of private operation, only to watch its market cap plummet from $6.2 billion to $2.8 billion. While most executives would spin this as temporary market volatility, Cohen reveals the real cost: "You have this mechanism that makes people obsessed on, I don't know, refreshing their screen and check what our share price is. It creates a burden to explain to people, your employees, basically." His candor exposes a fundamental tension in today's public markets , the gap between building a business and satisfying the minute-by-minute judgment of traders who Cohen believes "can't actually know why their share price goes up in this morning and goes down in that morning."

Cohen's frustration isn't about ego. It's about execution. He argues that public market behaviors "are not even relevant" to actual business performance, forcing leadership to spend time explaining stock movements instead of building products. This distraction becomes particularly acute when you're trying to retain talent at a company whose public valuation suggests decline while internal metrics suggest growth. The challenge intensifies in Navan's case because they operate in travel , an industry employees already questioned during COVID lockdowns. Now they must convince engineers to stay despite a stock price that suggests the market has lost confidence in their future.

But Cohen's decision to go public wasn't driven by ego or typical growth capital needs. The move was strategic, particularly for Navan's payments infrastructure. "In the payments business, I think there is huge advantage to be a public company in the way that you are actually raising capital for that part of the business compared to being a private company," Cohen explains. "If you kind of go too long in the payments business on being private, you may end up not where you want to be." This reveals something crucial about fintech scaling: private markets can't efficiently fund the capital requirements of payment processing at enterprise scale. Public markets provide both the capital structure and regulatory credibility that payment partners and enterprise customers demand.

The timing pressure Cohen describes suggests a narrow window for payments companies. Stay private too long, and you risk being outmaneuvered by public competitors who can raise cheaper capital and offer more credible partnership terms. This dynamic likely applies beyond Navan to any company where payment processing represents core infrastructure rather than a side feature.

Cohen's experience also illuminates how AI is reshaping competitive dynamics in unexpected ways. When he challenged his team to rebuild products faster, his cofounder delivered a stunning result: "Elon, over the weekend, completely vibe code our Expense product. There is nothing there. Like, there is a big fintech component, very similar to travel... But the actual app, super easy to vibe code." Six hours. An entire expense management product rebuilt from scratch over a weekend using AI tools.

This isn't just about development speed. It suggests that most SaaS applications contain far less defensible code than founders realize. The "big fintech component" , payment processing, compliance, integrations , remains complex. But the user-facing application layer that customers actually interact with has become commoditized by AI-assisted development. This means competitive moats increasingly depend on data, relationships, and operational execution rather than code quality or feature complexity.

Cohen acknowledges the uncertainty around AI's job impact but maintains optimism: "People are trying to estimate which jobs are going to get redundant and which jobs are going to be created. It's just impossible to know these things... Is the experience for all of us going to be better? Is our work life going to be better? I think yes because I'm optimistic." His response suggests leaders should focus on improving customer and employee experiences rather than attempting to predict which roles disappear.

The combination of Cohen's insights points to a broader shift in how technology companies should think about competitive positioning. Public markets provide capital advantages for infrastructure-heavy businesses like payments, but they also create distractions that can undermine the rapid iteration AI now enables. Companies like Navan must navigate between the quarterly expectations of public investors and the weekend rebuild cycles that AI makes possible.

The lesson for founders isn't to avoid public markets, but to prepare for the psychological overhead they create. Cohen's honesty about stock price obsession suggests successful public company leaders must actively shield their teams from market noise while leveraging public market advantages for infrastructure investments. The companies that master this balance , capturing public market capital benefits while maintaining private company execution speed , will likely dominate the next decade of enterprise software competition.
