At Mayday, we're dreaming big.

Our mission is to bring about real-time accounting for the finance teams of startups and SMEs.

Finance teams play a crucial role in their company’s success, with the unique capacity to deliver business insights and management information. Today’s finance teams are hampered by the time-consuming process of manually manipulating data each month end. We are creating a world where accurate accounting can be automated, freeing up time for finance teams to be able to deliver maximum value to their company.

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 in navigating the maze of month end. 

More broadly, Mayday originates from the French “m’aidez” - help me.

Too many of us are enslaved by antiquated processes that no longer make sense. As Mayday grows, we will be able to provide valuable help to more and more finance professionals, rescuing them from outdated systems and freeing up their time and attention to make space for bigger things.
