The latest company touting influencer-marketing technology is US firm Boostinsider, with its Social Book tool.
The company says it has raised $3.3m of funding so far for its service, which aims to help brands and marketers dig in to analytics of YouTubers they’re considering working with.
Its metrics include the ‘market value’ of each channel along with its audience demographics, how well its videos have performed, and what brands that YouTuber has mentioned in the past.
Boostinsider has been tracking stats for more than 350,000 influencers on YouTube as well as Instagram, Twitter, Facebook and Tumblr, and has worked with around 300 brands.
"With the use of machine learning and AI technology, we now can estimate the ‘price’ of any YouTuber in the world. We can also estimate the demographic data," said CTO Chen Wang in a statement.
"We can even estimate how many clicks and downloads you can get if you ask a specific YouTuber to do a potential promotional video for you."
Boostinsider is hoping to generate $10m of annual revenues from its business in 2018.
