AWS Summit
Bringing the cloud computing community together annually to connect, collaborate and discover the power of AWS.
Sleek has delivered the London Summit since 2015 and, alongside AWS, has grown the event from 3,000 attendees to over 22,000 in 2026, managing the end-to-end experience from concept ideation through to full production and delivery.
The 2026 Summit welcomed 6,500 attendees in the keynote alone, with over 300 speakers delivering 280 sessions, workshops and hands-on labs. The event also hosted more than 170 sponsors and over 150 AWS activations, creating a large-scale, multi-layered environment designed to support learning, networking and product exploration across the cloud ecosystem.The defining creative approach for 2026 was the “city” concept, which framed the entire space as a living, connected urban environment powered by AWS.
In London, the city theme was brought to life through familiar cultural references such as food markets, green spaces, neighbourhood-inspired zones like a high street and village square and even a good old British Pub. This created a sense of familiarity within a large-scale tech environment, making the experience feel more human, accessible and connected.
The result was a technology environment that felt human, accessible and rooted in everyday experience, helping translate complex cloud innovation into something more tangible and intuitive for attendees to navigate.
This overarching city narrative also extended beyond London, forming a cohesive framework across AWS’s wider European roadshow. For Amsterdam and Stockholm, the same overarching “city” framework was adapted with localised visual and environmental cues, ensuring each location felt authentic to its culture while remaining part of a unified European experience.
Alongside the flagship London Summit, Sleek also delivers smaller Summits across EMEA and approximately 30 additional AWS events each year.
We maintain consistency, creativity and operational excellence across the full programme.
