UK-based Lunio (formerly a digital marketing agency known as PPC Protect) pivoted towards ad fraud detection with the launch of its ad fraud solution in 2018. Its automated click fraud prevention platform can detect and prevent ad fraud across a variety of digital media. By using analysis of traffic and user behavior patterns, the platform can identify and exclude fake, non-human, and zero-value traffic, providing marketers with better insights into ad performance. The firm’s solution is compatible with 5 ad networks, including Google, YouTube, Facebook, Instagram, and LinkedIn. As of October 2022, the firm's solution is used by 1,000+ firms, including Hugo Boss, Marks & Spencer, McDonald’s, Blend Jet, and Europcar, representing more than 2,500 individual users.  

The firm plans to use the funds to accelerate the development of its technology as well as support its geographical expansion in the EMEA and North American markets.  

The firm claims that this is the largest amount raised in a series A round in the digital ad fraud space, underlying the confidence of investors in Lunio’s solutions, and has been recognized by G2 as a leader in its fall 2022 report.

Lunio, a digital ad protection solution, raised USD 15 million in Series A funding led by Smedvig Capital with the participation of Angel investors in the advertising space, including Google and Warner. This brings the total funds raised to date to ~USD 18 million.
