Webinar Recap: How Rimes and PANTA Are Accelerating Index Blending for the Modern Buy-Side

Rimes and PANTA came together to explore how investment teams can move beyond legacy index workflows and embrace a faster, more configurable, and provider-agnostic approach. The conversation centered on Rimes Index Analytics and PANTA allow firms to analyze, customize, and operationalize index strategies with unprecedented efficiency. 

This is exactly why Rimes and PANTA formed their partnership. Rimes brings decades of trusted data infrastructure and global coverage. PANTA provides a modern index operating system built for speed, flexibility, and cross-provider analysis. Combined, they give investment teams a way to move from idea to implementation far faster. 

As Tobias Sproehnle, CEO at PANTA, expressed during the session, “Speed and agility are no longer competitive advantages. They are table stakes.” He went on to describe the collaboration as “two organizations who have each built something the other could not replicate, coming together to deliver something the market genuinely needs.” 

A Modern Way to Build and Blend Indices 

A central part of the webinar was a live platform demonstration led by Mark Penfold, Head of Product at PANTA, who showcased how Rimes Index Analytics allows teams to open a blend, adjust exposures, compare performance and risk, and publish updated results back into the Rimes Lakehouse within minutes. The methodology builder stood out for its flexibility, enabling users to construct custom exposures from the ground up using rules, filters, rebalancing schedules, and capping. Each change produces immediate performance, risk, and exposure analytics, giving teams a fast, controlled environment to experiment and validate their ideas. 

What the Audience Wanted to Know 

Questions from attendees centered on themes like asset class support, data access, governance, and scalability. The discussion highlighted that any asset class Rimes calculates returns for can be blended, including equities, fixed income, alternatives, and private markets. Historical back testing pulls directly from the Rimes Lake House with no extra data loading. Firms can track usage down to desks and users, and quality control is supported through both Rimes data validation and PANTA-level thresholds and approval workflows. There was also interest in real-time capabilities, and while today’s environment focuses on end-of-day data, the underlying architecture can support expanded timing in the future. Throughout the Q and A, one message resonated strongly: investment teams want a faster, more independent way to move from analysis to action. Tobias captured this sentiment with, “The competitive advantage comes from being able to move from insight to implementation.” 

A Clear Path Forward for the Buy Side 

Investment teams no longer need to rely on slow, fragmented tools to evaluate index choices or build blended strategies. The combined strengths of Rimes and PANTA offer a faster, more flexible, and more scalable way to operate. Nicholas Wood, EDM Product Manager at Rimes captured the value succinctly: “With Rimes Index Analytics, you can calculate a blend quickly and publish it straight back into the Rimes Data Lakehouse.”
