Siena Capital Group hires Ridwan Bari as Chief Technology Officer

Siena Capital Group, LLC has announced that it has appointed Ridwan Bari as its Chief Technology Officer (CTO), to spearhead technology strategy across the firm’s portfolio companies and lead the development of Caterina, the Group’s insurance-linked securities platform.

Founded in April 2025 by Luke Meehan (Managing General Partner) and Jack Stone (Partner), Siena Capital Group operates as a private investment office with a focus on special situations.

Bari brings over two decades of experience in financial services technology to the firm. Most recently, he served as Global Head of Fixed Income, Derivatives, and Multi-Asset Technology at S&P Dow Jones Indices, where he led cloud-native platform development and technology transformation initiatives supporting more than $1 trillion in client AUM tracking S&P benchmarks.

As CTO, Bari will oversee engineering teams collaborating closely with Siena Capital’s specialists in research, catastrophe modeling, and ILS portfolio management. Together, they aim to build the Caterina platform from first principles, leveraging deep domain expertise to address real-market inefficiencies in the ILS market.

“I’ve always gravitated toward understanding clients’ needs, with a deep desire to learn what ‘value’ means from the customer’s perspective and how we can leverage technology to deliver that value,” commented Bari.

“Ridwan’s expertise in building enterprise-grade fixed-income, derivatives, and multi-asset products, combined with our key hires in ILS analytics and portfolio management, positions us to deliver scalable solutions to our clients,” said Jack Stone, CEO of Caterina and Partner at Siena Capital Group.

He added: “To our knowledge, there isn’t anyone of Ridwan’s caliber from traditional finance who has such a specialized focus on the insurance-linked securities market at the moment. His expertise positions us to deliver solutions that will fundamentally change how this industry operates.”

“Ridwan’s appointment demonstrates Siena’s commitment to hiring first-rate talent to create a positive impact in the industries that we choose to serve,” added Luke Meehan, Managing General Partner of Siena Capital Group.

“Being closer to top-class talent puts us in a great position to recruit from the best educational institutions in the world as we expand aggressively. I’m really excited about this opportunity and look forward to leveraging technology to bring about innovation and efficiency in the ILS ecosystem. Our goal is to build services and infrastructure that will fundamentally enhance transparency and create value for the end investors,” Bari further added.

Bari’s appointment follows a recent European roadshow, during which leading ILS managers expressed strong interest in the Caterina platform and its potential to meet pressing market needs.
