Bio

Founder of Jammed.app - powering online bookings for creative spaces

Andy has over a decade of app development experience, working with some of the UK's most exciting tech companies, and he has used this experience to develop Jammed.app. Jammed was born in 2019 after Andy's band couldn't book their favourite York rehearsal room online for practices, and spoke to the studio owner about the fact that no existing software fit the market. 

Working as a solo developer, he created the entire platform, marketed it and has now sold it to over 70 studios across 11 countries, taking over £1m in booking in 2023 all without taking outside investment. 

Andy also works as a freelance developer with micro and small companies across the UK to develop their web & mobile software products. The last project Andy worked on was 'Colemanator' - a multi-award winning app that allows house surveyors to calculate the risk of mould growth on interior walls.
