Key Focus Areas
The work with Sonin centred on enhancing the foundations that would support the platform’s continued success.
A core focus was maintaining platform quality and reliability, ensuring users consistently experienced a smooth, dependable app as the channel continued to grow. Alongside this, Sonin supported incremental improvements to the technical foundations, helping ensure the platform remained adaptable and future-ready without disrupting what already worked.
Equally important was deepening understanding of user behaviour. With the app serving both in-the-moment visitors and long-term planners, Sonin supported a more nuanced, user-led view of how different audiences engage with the platform and how it could continue to evolve to meet those needs.
Throughout, flexibility was key, enabling London & Partners to enhance the platform at a pace that aligned with their priorities and ambitions.




The Opportunity
The Visit London app was a growing digital channel, with increasing engagement and relevance as mobile usage continued to rise.
As the organisation looked ahead, London & Partners saw an opportunity to further strengthen and evolve the platform, ensuring it continued to meet changing user expectations while remaining flexible enough to adapt to a rapidly shifting digital landscape.
Rather than standing still, the focus was on reinforcing what was working well, maintaining a consistently high-quality experience, and ensuring the app could continue to grow in importance as a trusted destination for discovery and planning.
To support this, London & Partners sought a partner who could work alongside them over time, bringing technical continuity, product insight, and a shared commitment to long-term value.
The Solution
Sonin partnered with London & Partners to provide ongoing support for the Visit London app, combining technical expertise with product-focused thinking.
The approach was collaborative and measured. Rather than introducing unnecessary change, Sonin worked closely with the team to strengthen the existing platform, refine its technical foundations, and support longer-term thinking around roadmap and evolution.
Decisions were guided by a clear understanding of users, business objectives, and the wider context in which the app operates. This ensured improvements were purposeful, sustainable, and aligned with the organisation’s broader goals, enhancing the platform without overcomplicating it.
The result was a partnership built on trust, continuity, and a shared ambition to keep making a strong product even better.
The Outcome
Through this partnership, London & Partners continued building on the success of the Visit London app, reinforcing a high-performing digital channel while preparing it for future growth.
The platform remains a trusted destination for users, supported by stronger foundations and clearer thinking around its ongoing development. Most importantly, London & Partners gained a partner invested in the product’s long-term success, helping ensure it continues to deliver value as user needs and digital behaviours evolve.
