U.S. Mapbox raises $52.6 mln in Series B funding led by venture capital firm DFJ

U.S. provider of custom online maps for websites Mapbox has raised $52.55 million in a Series B round of funding.

The round was led by DFJ Growth with participation also from existing investors Foundry Group. DBL Partners, Thrive Capital, the Pritzker Group, Goldman Sachs and Promus Ventures all also chipped in.

Mapbox said that the main focus of the raise is growing its tech and global teams out, but also to buy strategic data assets, that will include more accurate geocoding data, and new satellite imagery that it can integrate into its own larger mapping database.

The company was essentially bootstrapped at first, barring a small injection from the U.S. private independent foundation Knight Foundation, until 2013, when it raised a modest $10 million from venture capital firm Foundry Group.
