Mercer & Syndio Partner to Help Clients Scale Compensation

Mercer, a global people and investment consultancy and a business of Marsh McLennan, has joined forces with Syndio, a decision-intelligence platform for pay and workplace equity.

As part of Marsh McLennan, Mercer is applying its expertise in workforce transformation and rewards strategy to reimagine how organisations manage compensation.

By aligning with Syndio, the firms have established a formal partnership to modernise compensation systems and governance with data-driven, defensible decisions.

Putting expertise into practice

Through the collaboration, Syndio will utilise its AI-powered pay governance, and Mercer will offer advisory expertise, providing clients with an integrated approach to designing, governing and executing pay.

“Compensation is entering a new era – one shaped by AI, increased transparency and higher expectations from boards and employees alike,” said Stephanie Penner, Mercer’s US and Canada Career Practice Leader. 

“Navigating it takes both deep advisory expertise and the right technology. Mercer chose Syndio because they bring the rigour our clients require, and together, we're giving enterprises a modern, connected experience that changes how companies make pay decisions across the organisation.”

Creating smarter pay decisions for customers

The firms aim to bridge strategy and execution through a reciprocal partnership that enables clients to move from diagnostics to action at scale.

Mercer will serve as a strategic advisory partner to Syndio’s enterprise customers, ensuring that advanced analytics are grounded in market-leading human capital insights, reward governance, and change management.

By integrating Syndio into Mercer’s technology ecosystem, clients gain an automated pathway to scale pay equity programs that were once manual and episodic, enhancing auditability, speed, and enterprise-wide consistency.

Syndio’s platform is underpinned by nearly a decade of proprietary pay equity methodology, and Syndi, its purpose-built AI, embeds intelligence into analysis and decision-making to deliver rigorous, defensible outcomes.

“Mercer has set the standard for compensation strategy for decades,” said Erik Darby, President of Syndio. “Together, we’re giving enterprises a clear path through one of the most important transitions they’ll face: using AI to make pay decisions that are faster, fairer, and more strategic. It’s a powerful combination of advisory depth and technology built to meet this moment.”

By harnessing Mercer’s global compensation expertise and market data, Syndio’s customers gain a faster, more confident route to achieving pay equity at scale.

With a stronger strategy-to-execution model, clients can elevate governance, improve decision quality, and generate richer, more actionable intelligence.

Collectively, this marks a step-change in the rewards landscape – shifting from siloed, episodic processes to an integrated model where technology and expert judgment reinforce one another. In doing so, Mercer and Syndio equip leadership teams with the clarity, accountability, and defensible analytics needed to steward complex compensation investments in an era of heightened transparency.
