Guru, the Center City business applications software that built "a browser extension to give your team access to information everywhere" through a Slack bot linked to the Guru app, says it has raised $9.3 million from investors led by its early-stage backers, FirstMark Capital and Dell Computer founder Michael Dell's MSD Capital.

Guru, whose founders include former Dell Boomi executive and Philly Start-up Leaders chief Rick Nucci, says it now has "over 300 paying customers," including Shopify, Square, Intercom, Greenhouse, and Optimizely, as well as Wayne-based Dell Boomi, "all of which have replaced their legacy knowledge portals" with Guru's solutions.

Traditional knowledge management systems weren't designed to solve modern-day business problems — they were simply a basic way to store and access content. Companies now need solutions that fit into modern workflows, and enable teams to collaborate internally and externally as quickly and confidently as possible.

The company, which employs around 30, says it plans to use the proceeds to boost its engineering and sales staff "in both Philadelphia and San Francisco."
