Siebert Financial Expands Executive Team with New CMO Stefano Marrone

MIAMI and NEW YORK, April 23, 2025 (GLOBE NEWSWIRE) --  Siebert Financial Corp. (NASDAQ: SIEB), a diversified financial services company, has appointed Stefano Marrone as Chief Marketing Officer. Marrone will direct marketing for all divisions (including Siebert.Valor, Siebert.SPS, and Gebbia Media) to advance the firm’s mission of delivering “Financial Freedom for Everyone.” A key focus of his role will be bringing media production and financial literacy together, leveraging the unique presence of Gebbia Media within Siebert Financial.

In 2024, Marrone led Siebert Financial’s successful rebrand and rolled out a modernized website as a consultant, working closely with Siebert’s leadership. That initiative drove notable brand growth and client engagement. He brings extensive experience collaborating with leading financial institutions such as J.P. Morgan, UBS Asset Management, and HSBC, as well as tech giants Google and Meta. Marrone also founded and exited a content agency, demonstrating an entrepreneurial spirit that fuels bold marketing and strategic thinking.

“Stefano’s ability to deliver fresh thinking has already energized Siebert Financial,” said John J Gebbia, CEO of Siebert Financial. “He helped spark our rebrand last year, and we’re excited about his vision to engage the next generation of investors, which will keep us ahead in a competitive market.”

Marrone will focus on creative campaigns, AI-driven marketing, and brand development. He aims to build innovative content solutions that increase both financial literacy and client engagement, particularly through Gebbia Media’s production capabilities.

“Stefano’s commitment to modern content resonates with our goals,” said David Gebbia, Principal at Siebert Financial and CEO of Gebbia Media. “Bringing together media production and financial education under one roof is a rare advantage for a financial firm. His background in storytelling and AI will help us create dynamic content, bridging entertainment and financial literacy for clients of all ages.”

Siebert.Valor’s mission to reach veterans and military families remains key to the company. Marrone will ensure messaging and educational resources reach those audiences effectively, reflecting the firm’s broader commitment to inclusivity.

“Stefano has a gift for making complex topics like financial education feel clear and empowering. His approach will help us better support our veterans and active-duty communities,” said Kaj Larsen, Head of Military Investment and Communications at Siebert.

Marrone sees bold leadership and unified media resources as keys to building on Siebert Financial’s legacy of innovation in finance.

“I am excited to join a financial brand with such a rich history,” said Marrone. “Working with the Gebbia family has shown me how forward-looking leadership can reimagine a legacy institution. Combining Gebbia Media’s creative capabilities with robust financial education to engage with a younger audience segment is a powerful strategy. I’m honored to help shape the next chapter of Siebert Financial as we continue to innovate in an industry that strongly needs it.”
