Viigo, a Canadian maker of a content mobilization platform, said that RBC Venture Partners has made a CA$1.5 million (US$1.49 million) follow-on investment to Viigo’s first round of venture capital funding, which closed in December last year. This brings the total invested amount (including angel funding) to CA$7.9 million (US$7.86 million). Viigo will use the investment to accelerate the release of its new product Project Tango, due for public beta release in June. David Unsworth, Director at RBC Venture Partners, will join Viigo’s board of directors.
