Havas' Prose on Pixels trio promoted in growth spurt

Havas’ AI-powered global content network, Prose on Pixels, has made a series of senior appointments following accelerating global growth and continued investment in more sophisticated service models across the globe.

The UK-based global team has welcomed three major leadership positions, building on the recent expansion of its client portfolio with major global brands.

Kate Johnson steps into the role of UK senior vice president of operations, in recognition of her leadership within the network over the past two years.

With nearly two decades of experience building and leading high-performing studios at organisations such as Oliver Agency and Chelsea Football Club, she brings deep expertise and proven rigour to the network.

In the expanded role, Johnson will continue to strengthen Prose on Pixels’ end‑to‑end delivery model as the business scales globally.

To further elevate the agency’s client service offering, Lani Carstens has been appointed as global vice president of client services.

Bringing over two decades of experience leading content marketing, production at scale and creative operations across global businesses such as Dentsu and WPP, Carstens will play a key role in advancing the agency’s strategic approach to client service – focused on responding to the evolving demand for more personalized, audience-led solutions.

Meanwhile, after more than five years driving growth at Havas Creative Network, Aimee Healey has joined Pixels on Prose as global new business director, where she will lead the development of commercial opportunities and champion the evolving role of production in the industry.

Recognised for building meaningful partnerships, Heeley brings a decade of expertise in unlocking growth and scaling businesses internationally.

These appointments follow a wave of client wins – including four world-leading brands across technology, travel and tourism and pharma.

Prose on Pixels president of global network and UK chief executive Paul Ward said: “We’ve started 2026 with a bang and bringing such a high calibre of talent into our leadership team has made us significantly stronger. As we continue to expand our global footprint and elevate the quality of our delivery, adding Kate, Lani and Aimee to the team ensures we’re both meeting the industry’s new demands and anticipating what our clients will need next.

“Lani, Kate and Aimee each bring a depth of expertise that will strengthen our global operations and help us scale with intention and excellence. Exceptional client service doesn’t happen by accident. It’s built through strong leadership, empowered teams and clear ways of working. We’re committed to setting a new standard for what we can achieve on the global stage.”

The agency’s global expansion has been underpinned by the integration of production capabilities across markets and within the broader Havas network – creating a more unified and scalable, audience-led model for content delivery.

This strategy also supports Havas’ Converged.AI vision; an AI‑enabled approach that unites expertise, platforms and capabilities to deliver seamless, cross‑functional communications solutions.
