Headline Act Teaser and Gold Sponsors for 2025

Wowzers… it’s less than three weeks now until London’s Calling 2025 – the 10th edition of Europe’s largest community led conference for Salesforce professionals.

You may know by now that we like to break-away from the standard keynote, and this year is no exception. Our headline act is… still under wraps.
No title.
No lineup.
No previews

But we can give you a little teaser… something unexpected will take over our main room – a finale filled with surprise, rhythm, and a few things you won’t see coming.

Voices will rise. Things will shift.
Expect movement, moments, and more than one mind behind it all.

You won’t know what you’re walking into.
But by the end, you’ll wish you could see it again.

So if you haven’t done so yet book your spot now to the hottest ticket in town.
