On Device Strengthens Senior Leadership Team with New COO Appointment & Internal Promotion
by on 20th Oct 2026 in News

On Device, the Brand Lift measurement company built for the Outcomes Era, has strengthened its senior leadership team with the appointment of Meg Fisher as chief operating officer (COO) and the promotion of Sami Smith to commercial director, as the company enters its next phase of growth.
Fisher will work closely with On Device’s founders and leadership team to support the continued scaling of the business, with a particular focus on the company’s technology and product roadmap, operational strategy, and international growth.
The appointment comes as On Device continues to scale its technology and product offering, including the recent launch of its Brand Lift Data API, which enables partners to integrate high-quality, log-level Brand Lift data directly into their technology stacks. The launch forms part of On Device’s wider evolution towards making Brand Lift data more actionable and better integrated into the systems that power advertising decisions.
Fisher brings extensive experience helping data and technology businesses scale. Having started her career as a research scientist, working across data, statistics, and experimentation, she has spent the past decade working with venture capital and private equity-backed businesses, helping growing companies build the operational foundations needed to scale. Her experience includes supporting businesses through periods of growth by improving processes, harnessing data and technology, and turning innovation into repeatable, scalable products and services.

Commenting on her appointment, Meg Fisher, COO at On Device, said: "What stood out to me immediately about On Device was the quality that runs through the business, from the technology and research to the people behind it. There is a real understanding here that clients increasingly want answers quickly, but that speed cannot come at the expense of rigour or quality."
"On Device has an exciting opportunity to build on those foundations as it grows. My focus will be on helping us scale in a way that makes our technology and products increasingly accessible to clients, supports expansion into new markets, and ensures we retain the quality that differentiates the business as we grow."
Sami Smith, commercial director at On Device, said: "Having been part of On Device for almost a decade, I’ve had the opportunity to see the business evolve significantly and to work closely with many of the clients that have grown alongside us. I’m excited to take on this new role at such an important stage for the company and to continue building on those relationships as we grow our offering and work with more partners around the world."

Alistair Hill, CEO and co-founder at On Device, added: "Meg and Sami bring different but complementary strengths to our leadership team as we enter our next phase of growth. Meg’s experience helping data and technology businesses scale will be invaluable as we expand internationally and evolve the ways our Brand Lift data can be used by clients."
"Sami has played an important role in On Device’s growth for many years, building trusted relationships with some of our largest clients and developing a deep understanding of what they need from measurement. His promotion reflects his contribution to the business to date and the increasingly important role he will play in our commercial growth going forward. Together, these changes strengthen the team we have in place to build for our next stage while retaining the quality and rigour that have always been fundamental to On Device."
The appointments follow continued investment in On Device’s international leadership and commercial teams. Earlier this year, the company appointed former Kantar executive Josh Rucker as VP of US sales following a more than fivefold increase in US studies.
