Tuum Appoints Renato Cassinelli as Head of Marketing to Drive Strategic Growth

Tuum the next-generation core banking platform, announced the appointment of Renato Cassinelli as its new Head of Marketing. A seasoned B2B fintech marketing leader, Renato brings over 15 years of experience building high-impact marketing engines across financial services and SaaS.

His appointment marks a significant chapter in Tuum’s evolution, defined by increasing commercial traction, deepening analyst recognition, and a growing roster of financial institutions modernizing on the Tuum platform.

Renato joins at a time of strong momentum. Tuum was recently named a Major Player in the IDC MarketScape for Digital Core Banking Platforms 2024, awarded Best Challenger Core Banking Platform at the Banking Tech Awards, and continues to power transformation for leading banks and fintechs including LHV Bank, Zenus Bank, OP Pojhola, and Multitude Bank.

Since early 2023, Tuum’s marketing has been supported in partnership with Aperture. As we enter our next phase of expansion, we are bringing the function fully in-house. This is a natural step in our evolution. It allows us to take full ownership of our strategy as we scale our operations and drive the next chapter of growth.

“Tuum is already seen as one of the most credible players in modern core banking,” said Renato Cassinelli. “The technology is proven, the clients are referenceable, and the market opportunity is substantial. My role is to amplify that story, consistently and credibly, across the buyer journey, in every market we touch.”

As Tuum continues to scale across verticals, BaaS, Lending, Islamic Banking and EMIs, marketing will be instrumental in sharpening positioning, driving insight-led execution, and supporting Tuum’s market expansion plans.

“Renato’s appointment couldn’t come at a better time,” said Miljan Stamenkovic, Chief Revenue Officer at Tuum. “We’ve laid a solid foundation: proven product, growing client base, and strong analyst endorsement. Now we’re doubling down on brand, positioning, and pipeline. Renato brings the experience, strategic clarity, and execution mindset to take our go-to-market to the next level.”

“There’s real momentum here,” added Renato. “We’re seeing strong traction in multiple segments, and what’s exciting is how repeatable that success is. The challenge now is scale, and I’m looking forward to helping lead that next phase of growth.”
