A new start-up is attempting to modernize the investor relations industry to meet the surge of new retail investors.

Swedish start-up Quartr recently raised $4.5 million to help build out its product, which includes recordings of earnings calls and financial documents from major companies. Investors in Quartr include executives at the Ritholtz Group — such as Barry Ritholtz, Michael Batnick and CNBC contributor Josh Brown — and former Spotify executive Peter Sterky.
