Based in London, WeArisma partners with brands, including Unilever and Coty, helping them evaluate their investments in celebrities and influencers.

The latest investment round was provided exclusively by investment syndicate Adjuvo. To date, WeArisma has raised a total of £3.5m.

WeArisma CEO Jenny Tsai said: “There are 4.5 billion social media users across the world and most of these people are making purchasing decisions based on third-party content they are viewing and yet, most companies still don’t understand how their brand and products are performing on these third-party feeds. The value of earned media is still under-discovered”.

The startup says it will use the funds to introduce new features including boosting its coverage of social channels in APAC and globally.

WeArisma says it will also scale up its team as it looks to enhance its offering.

Mark Foster-Brown, co-founder and CEO of Adjuvo, said: “Assessing the value and effectiveness of influencer marketing is critical for retailers and brands.”

Sanghamitra Karra, managing director and EMEA head of the multicultural client strategy group at Morgan Stanley said: "WeArisma has a data-driven approach that has helped clients to optimise marketing spend and achieve their communication objectives."
