Today, lead generation firm Radius has raised $13 million in funding from Formation8 Partners. BlueRun Ventures and Radius chief Darian Shirazi also participated in the said round, according to VentureBeat.

The San Francisco-based firm tracks various kinds of business data and makes them available for its clients to search through. This enables Radius' customers to find which ones they should contact. Data are sourced from different sources including Facebook, Twitter, LinkedIn, products and services reviews, and even company websites, the report detailed.

Radius creates smart lists that funnel into the Salesforce customer relationship management (CRM) app. The app keeps the lists on top of leads, so clients don't have to go back and forth. In the event that Radius clients don't use Salesforce, the company can export a basic spreadsheet, the report explained.

The new capital will help Radius gather more data sources and beef up its salesforce, according to a press release. The company will also use the funding to hire more people for its technology and data teams, the report stated.

Radius has raised a total of $28 million to date. The company's customers include American Express, Home Depot, and TaskRabbit. A spokeswoman said the firm presently employs 40 full-time workers, VentureBeat reported.
