Rapid Growth for Ad Testing Firm System1

Ad testing and measurement firm System1 Group has announced half year revenues up 38% to £18.3m, led by the US where platform revenue has doubled.

System1 was founded as BrainJuicer in 2000 by current President John Kearon, and has operations in Europe, North America, Brazil, Singapore and Australia. The firm uses a database of more than 100,000 ads and allows clients to compare their ads against competitors. Its Test Your Ad (TYA) and Test Your Innovation (TYI) solutions quickly predict the short- and long-term commercial potential of ads and ideas, while Test Your Brand (TYB) measures the impact of ads and ideas on brand health.

In a trading update the firm said it had won more than 160 new clients in the last half-year ('H1 FY25'), while revenues have risen fast across its data sales and data-led consultancy divisions: up by 48% and 76% respectively. These two make up System1's 'Platform' business which accounts for just over 90% of the total (£16.7m, up 53% overall). US growth was in large part due to the success of Test Your Ad solution.

CEO James Gregory comments: 'I am delighted that our focus on winning in America is delivering strong growth and financial results. We are continuing to win and retain business with the world's largest advertisers and will be accelerating and significantly increasing investment in the coming months to build our position in America and revitalise System1's Innovation proposition'.
