Mobile app intelligence provider Apptopia has raised $2.7 million in its second round of seed funding.

The latest investment round was led by Ashton Kutcher's and Guy Oseary's Sound Ventures. It brings the company’s total funding to date to $5 million.

Market transparency

Apptopia aims to use the investment to improve its suite of tools as it bids to make a more transparent app economy for publishers.

In the last year, the company has doubled its headcount from 18 to 42 across its offices in Boston and Kiev.

"We've seen tremendous growth over last year, tripling annual recurring revenue since the beginning of 2016," said Apptopia CEO Eliran Sapir.

Apptopia’s clients include Google, Facebook, Chartboost, Fyber and NBC Universal.
