OneSales was founded by Seamus Devine and Jiri Zajpt.

Seamus has been in enterprise software and sales since 1995 and previously founded ClosePlan, a sales execution platform that was acquired by People.ai. Jiri has over 20 years of engineering experience and previously founded Blueberry Apps, a software development firm based in Prague.

Both founders have spent their careers close to the problems OneSales solves. The platform is built by people who have lived the pain of manual account research, incomplete buying team visibility, and missed signals.
