Lob, an API provider, has announced it raised $7 million in Series A financing. Polaris Partners led the round that also saw participation from Floodgate and First Round Capital. Lob's suite of APIs eliminates the complexity of printing and mailing for its customers by allowing developers to send physical mail as they can send email (simply sending along an address with the content that they wish to be printed). Pat Kinsel of Polaris Partners will join the company's Board of Directors. Lob has now raised over $9 million in venture funding. In late 2013, it announced $2.4 million in seed funding.
