27.09.16 Google-centric CRM ProsperWorks raised $24M

ProsperWorks, a cross-platform customer relationship management (CRM) service that plugs into the Google for Work platform, has raised a $24 million. The company plans to use the new capital to invest into its technology and to grow its sales and marketing team. The funding comes at an interesting time for enterprise companies that sit on top of Google’s productivity suite. Google’s renewed interest in the enterprise means that (assuming Google’s plans work out) the platform will continue to grow. If that happens, it can only mean good things for the businesses in its ecosystem. Being so closely tied to Google comes with some risks, though. Google could release its own deeply integrated CRM solution, for example.
