Ideas so strange they might just work.


Every so often we have an idea that is too odd, too ambitious, or too early to put in front of a client. This is where those ideas live. Labs is our playground: somewhere to try out experimental formats, tools, partnerships, and half-built prototypes, and to find out which ones have legs. Nothing here is finished, and that is rather the point. If you are the adventurous sort, we would love your help. Take a look at what we are building, tell us what works and what does not and how you can help us make these ideas take flight.

Event Spy


Anyone who has sat through a conference with broken wifi, over long keynotes and a suspiciously vague agenda knows the brochure sometimes does not match the reality. Event Spy is our idea for fixing that: a place where people who actually attended an event can say what it was really like, long after the marketing has faded. Think TripAdvisor meets IMDb, but for events. Good organisers would have a shop window for their hard work. Bad ones would have nowhere to hide.

If you organise events, run a venue, or just have strong views on conference coffee, we would like to hear from you.

Speak UP for Sustainable Events


This one is about changing the conversation before the event even happens. We are building a campaign to encourage speakers and presenters to incorporate sustainability into their speaking briefs. That might mean asking clients whether the event could work as a hybrid format, suggesting video content instead of flying halfway across the world, or simply making sustainability part of the agenda rather than an afterthought.

If you are a regular speaker, a conference organiser, or a professional body that represents people in the speaking circuit, we want to hear from you.

Pocket Wilderness Project


We are working on a way to leave a lasting environmental impact at event venues by installing low maintenance biodiversity features. Think moss walls, insect nesting panels, deadwood habitats, and wildflower frames that thrive in urban spaces without needing constant attention.

The aim is to integrate these into event design so that every conference or corporate gathering leaves behind something that supports local ecosystems. We are currently researching suppliers, testing installations, and looking for venues in London and beyond who want to pilot this. If that could be your venue, or you would like to help, get in touch.
