Our Story
Founded by award-winning, serial entrepreneurs, with deep experience in accounting technology


David started his career at Deloitte, qualifying as a Chartered Accountant and Chartered Tax Adviser. He led a succession of startup and SME finance teams. He spent seven years as the Founder & CEO of Chaser. He built it into the market-leading accounts receivable software for startups and SMEs, winning Xero’s App Partner of the Year in 2016 and AccountingWEB Cloud App of the Year three years in a row 2017-19.


Griff is a serial startup technologist and machine learning expert. He graduated top of his class in Computer Science from the University of Warwick. Griff became the CTO of marketing technology startup Idio at the age of just 24, where he and David met. During his 7 years at Idio, Griff helped drive the business through three funding rounds, international expansion and grew the Software Engineering team to 12 people. After four years as the CTO of HR software Rungway, Griff and David joined forces to co-found Mayday together.

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 bogged down 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 As Mayday grows, we will be able to provide valuable help to more and more finance professionals, rescuing them from outdated systems and freeing up their time and attention to make space for bigger things.
