Zinat will be responsible for developing innovative yield management tactics to assist UK publishers in maximising the revenues from their unsold ad inventory.
Other service roles at Improve Digital have been taken up by Kevin Le Gall and Fernando Huguett, for France and Spain respectively.
Both will be responsible for integrating online publishers with the Pubmatic technology platform used by Improve Digital for its ad networking optimisation service.
Joelle Frijters, CEO and co-founder of Improve Digital, said: "Despite an ambitious business plan from day one, we have grown even faster than we expected, particularly in view of the global recession.
"Ad network optimisation is a relatively new industry. But what is clear from our rapidly expanding client base is that online publishers are welcoming new tools that enable them to work effectively with ad networks and exchanges, at the same time as retaining control.
"Our new team members will help us continue to roll out our offering and educate the market about the benefits offered by new technology."
