At Mayday, we're dreaming big.

Our mission is to emancipate expert knowledge and human experts themselves. We believe the world of expert knowledge in 20 years’ time looks unrecognisable from today’s professional services industry. We’re inspired to create that future.

Why the name Mayday?

Mayday is the international standard call for help. We’re answering that call for startups and SMEs looking for the advice they need on how to expand internationally. More broadly, Mayday originates from the French “m’aidez” - help me.

The first responsibility of a human expert is to help their client. Today’s professional services industry has lost sight of that. Our mission is to restore that focus and build Earth’s most client-centric company.
