Cambridge ebook bargain-finding service BookBub has raised $7 million in new funding led by Avalon Ventures, consisting of both equity and debt, the company announced Tuesday.
The service, which provides daily e-mail alerts on ebook deals, now has more than 5 million subscribers. The alerts include both free and discounted titles, BookBub says.
Avalon was joined by NextView Ventures, Founder Collective and Bloomberg Beta in the new round. All of those investors took part in the company's $3.8 million Series A round a year ago.
Prior to that round, the company had been bootstrapped since its launch in 2012.
