Founder story
Leadsie was founded in 2020 by Johannes Radig and Robert Desmond in London, United Kingdom. Originally started during lockdown as a project for marketing agencies, the founders pivoted after speaking with dozens of agency owners. They discovered that requesting asset access was the biggest administrative headache for agencies and built Leadsie to simplify client account access.
