Sinch Bets on Internal Talent to Steer Its Global People Strategy

STOCKHOLM, SWEDEN – December 15, 2025 – In a move that underscores a commitment to continuity and internal talent development, global customer communications leader Sinch AB has appointed Lindy Puttkammer as its new Chief Human Resources Officer (CHRO), effective January 1, 2026. The appointment sees Puttkammer, an internal leader who joined the company in 2024, elevated to the C-suite, where she will report directly to CEO Laurinda Pang.

The decision comes as Sinch, a powerhouse with over 4,000 employees across more than 60 countries and USD 3 billion in 2024 net sales, navigates the complexities of a business built on both rapid organic growth and a string of major acquisitions. Pang highlighted the significance of the internal promotion in the company's official announcement.

"It is always a special moment when we are able to promote an exceptional leader from within our own organization," said Pang. "Lindy's deep understanding of our culture and business, combined with her comprehensive expertise, makes her the ideal person to lead our HR department forward."

The Strategic Heart of an M&A Engine

For a company of Sinch's scale and history, the CHRO role is far from a traditional administrative function. It sits at the very heart of the company's growth engine. Over the past four years, Sinch has executed a highly aggressive acquisition strategy to cement its position in the Communications Platform as a Service (CPaaS) market. This spree included the USD 1.14 billion acquisition of U.S. voice provider Inteliquent, the USD 1.3 billion purchase of business messaging leader MessageMedia, and the monumental USD 1.9 billion deal for email delivery platform Pathwire.

These acquisitions, among others, have transformed Sinch into a global behemoth but have also created a formidable challenge: integrating disparate companies, technologies, and, most importantly, cultures. This makes the human resources function a critical strategic partner in realizing the value of these multi-billion-dollar investments.

The importance of this task was implicitly acknowledged in CEO Pang's praise for the outgoing CHRO, Christina Raaschou, who will remain until the end of February 2026 to ensure a smooth transition. Pang noted Raaschou’s "significant contributions... particularly in the vital work of integrating our acquisitions." This commendation sets a clear precedent for Puttkammer, whose primary challenge will be to continue weaving together the various cultural and operational threads of Sinch's acquired entities into a cohesive, high-performing global organization.

A Blueprint for Stability and Succession

By promoting from within, Sinch is executing a classic, yet often overlooked, strategy for ensuring stability during periods of intense growth. Puttkammer is not an outsider needing to learn the intricate web of Sinch’s history. Since joining in 2024, she has served as Head of HR for the Americas and, more recently, led the company's global Compensation and Benefits function. This experience provides her with a ground-level understanding of the company's diverse workforce and the unique challenges present in its largest markets.

Her background before Sinch, which includes over a decade in senior HR leadership at Lumen Technologies, further equips her with the experience of managing human capital within a large, complex technology and communications firm. This combination of external perspective and recent internal immersion makes her a uniquely qualified candidate to steer the company’s people strategy.

Choosing an internal leader signals a commitment to the existing strategic direction and provides a sense of continuity for the thousands of employees who have joined the "Sinch family" through its many acquisitions. An external hire might bring fresh ideas but could also introduce disruption at a time when the organization is still focused on harmonization. The planned two-month handover period between Raaschou and Puttkammer further reinforces this message of a deliberate, stable, and thoughtfully managed leadership transition, a best practice in corporate governance that investors and employees alike will find reassuring.

Weaving a Global Workforce Together

Beyond M&A integration, Puttkammer’s mandate will involve navigating the immense complexity of nurturing a 4,000-person workforce spread across a global footprint. This is where the intersection of technology, health, and food innovation—or in this case, the human element of a global tech enterprise—becomes paramount. The challenge is to build a unified corporate culture that not only respects but leverages the vast diversity it has acquired.

Under CEO Laurinda Pang, Sinch has already established a strong commitment to Diversity, Equity, and Inclusion (DE&I) as a core business driver, not just an HR checkbox. With women comprising 42% of the management team and 40% of the board, the company has demonstrated a tangible commitment to diverse leadership. Puttkammer will be tasked with embedding this philosophy throughout the entire organization, ensuring that every employee across its 60-country presence feels valued and has a voice.

Her recent leadership of the global Compensation and Benefits function will be particularly crucial. Designing equitable, competitive, and culturally relevant reward systems across such a wide range of markets is a monumental task that directly impacts talent retention and employee morale. In the fiercely competitive tech sector, where attracting and retaining skilled professionals is a constant battle, a sophisticated and fair approach to total rewards is a powerful strategic advantage.

Ultimately, Puttkammer’s success as CHRO will be measured by her ability to build the human infrastructure that supports Sinch’s next phase of growth. This involves more than just standardizing HR systems; it's about fostering a global culture of innovation, creating clear pathways for career development to retain top talent, and ensuring that the company's diverse workforce becomes its greatest competitive asset. As Sinch continues to connect businesses with customers, its new CHRO is tasked with ensuring its own people remain deeply connected to the mission and to each other.
