Amplified is proud to share that our founder, Dr Karen Nelson-Field, has been named #2 on Performance Marketing World’s 2025 International Powerlist - a global celebration of the most influential minds in performance marketing.

The annual Powerlist recognises the marketers, technologists and business leaders who are redefining what success looks like across the industry. Landing second spot is a powerful endorsement of Karen’s trailblazing work in attention measurement, and her role in pushing the marketing world to move beyond clicks, impressions and outdated metrics.

Since founding Amplified in 2017, Karen has helped shape the attention category from the ground up - championing measurement standards that are predictive, human-centred and grounded in real-world impact. With over 38 billion data points and clients spanning top global platforms, brands, and agencies Amplified continues to lead the charge in redefining media performance.
