Ada Health is out to disrupt healthcare - and the German app's data is signaling rapid growth and rising engagement. 

Ada ($ADAHEALTH) raised new funding in 2017, and embarked on an international expansion spree, launching operations in the US. Over the last year - tracked by our first chart, which provides a view of LinkedIn ($NASDAQ:MSFT) Employee Headcount - Ada staff numbers have nearly doubled. 

According to Crunchbase, Ada has raised a little more than $69 million since its 2011 founding from backers including Access Industries, Len Blavatnik’s investment group. Founders are Claire Novorol, Martin Hirsch and Daniel Nathrath. 

Ada engagement continues to rise - and, to do so steadily. Our last chart tracks Apple ($NASDAQ:AAPL) Store Ratings Count, which reflects a 67% rise over the course of 2019. The company provides a chat interface that replicates the intake process, before matching symptoms and potential patients with doctors. 

And, recent tallies tracking its average rating reflect users love Ada - it scores a 4.8 out of 5. 

About the Data: 

Thinknum tracks companies using the information they post online - jobs, social and web traffic, product sales and app ratings - and creates data sets that measure factors like hiring, revenue and foot traffic. Data sets may not be fully comprehensive (they only account for what is available on the web), but they can be used to gauge performance factors like staffing and sales.
