Siebert Financial appoints creative strategist Stefano Marrone as CMO to fuse financial education with bold media innovation across its divisions.

Siebert Financial Corp. has appointed Stefano Marrone as its new Chief Marketing Officer, tasking the award-winning strategist with redefining how financial services engage modern audiences. The move signals Siebert’s ambitions to break with industry convention—infusing storytelling, AI, and media production into a sector long dominated by jargon and tradition.

Marrone, previously serving as Siebert’s fractional CMO, played a central role in the firm’s 2024 rebrand and the launch of its media arm, Gebbia Media. His elevation to the top marketing role reflects the success of that transformation—and the company’s intent to scale it further.

With 17 years leading creative campaigns for clients including Google, JP Morgan, and Coca-Cola, Marrone’s appointment brings firepower typically reserved for entertainment and tech giants. Notably, his financial sector work—such as UBS’s The Red Thread and J.P. Morgan’s The Story of Trading—has stood out for translating complexity into compelling, accessible narratives.

At Siebert, Marrone will oversee marketing across its full portfolio, including Siebert.Valor and Siebert.SPS, aiming to build content that serves not just customer acquisition, but education—particularly for younger, more diverse investor segments. His remit includes harnessing AI tools and immersive storytelling to bridge the gap between media and finance.

“Stefano has a gift for making complex ideas clear,” said Kaj Larsen, who leads military outreach at Siebert. “That’s exactly what financial literacy needs right now.”

As the industry contends with generational turnover and heightened scrutiny, Siebert’s bet is clear: the future of finance may hinge less on product—and more on how well a story is told.
