Brussels-based app store optimisation tool AppTweak has raised $22 million from early investor Groupe Rossel in a series B round. This fresh round of funding is expected to expand international presence, most notably through the additional office openings in the APAC region. Founded in 2014 by Sébastien Dellis and Olivier Verdin, AppTweak continues to set the standard for app store optimisation (ASO) and has been profitable since 2017. They reported a 956.76% growth in sales revenues between 2016 and 2019, and currently count offices in four cities, Brussels, San Francisco, Tokyo, and Bengaluru with 47 full time employees speaking 16 languages. We are convinced that this investment will allow AppTweak to become a worldwide organisation, and develop the best ASO tool for apps and games,” comments Bernard Marchant, CEO of Rossel.
