They developed a solid platform and infrastructure enabling merchants to create relationships with affiliates. In 2000 Tradedoubler initiated a roll-out to all major European markets and by the end of that year the network was counting more than 260 affiliate programs in diverse fields and over 70,000 affiliates.

In 2005 Tradedoubler was listed on NASDAQ Stockholm and launched their white-label application, a global partner management platform that allows advertisers and agencies to track and manage their digital marketing activities.

In March 2006 Tradedoubler bought for US$ 1.25 million an advertising service Advertigo that was created by Daniel Ek, the future founder of Spotify.

In September 2015 Tradedoubler launched Cookieless tracking technology to allow online behavior to be tracked, even when a HTTP cookie is not present, by creating a device fingerprint. In 2016 Tradedoubler launched User Journey Insights as part of their business intelligence tool for giving advertisers visibility of their online customer journeys from affiliate data to the full spectrum of their digital marketing activity. The company also launched Cross-Device Tracking, a service for analysis of the impact of marketing activity across desktop and mobile. The same year Tradedoubler expanded their performance marketing offering to South East Asia with a new office in Singapore to develop performance marketing strategies across the Asian region and the company acquired R Advertising, an email marketing company. In 2016 Tradedoubler also introduced their programmatic service helping advertisers to identify potential new customers.

In 2017 Tradedoubler acquired Metapic, a platform for product recommendation within influencer and premium lifestyle media. Six months later the platform has attracted 20,000 users with a reach of more than 2 million unique visitors per week in Sweden, Norway and Denmark. During 2018 Metapic has been rolled out in the UK, France, Germany, Poland, Spain and Italy. In November 2018 Reworld Media announced a recommended public cash offer to the shareholders and held 40% of Tradedoubler's shares after the offer expired. In March 2019 Tradedoubler announced its product vision of an open platform enabling automated and transparent direct relationships between advertisers and publishers using blockchain technology for the storage of data. The same month it presented a new publisher interface and API as the first applications based on the platform.
