Flipboard to Close Additional $50 Million Investment Tomorrow

Flipboard, which recently raised $50 million in new funding in a round led by Rizvi Traverse Management and Goldman Sachs, will file information about an additional $50 million investment from Rizvi tomorrow, said sources. The expansion of its Series C funding means that Flipboard will have raised about $160 million in total, and puts the valuation of the Silicon Valley startup that makes the popular social reading service that has 100 million active users at $800 million. The possibility of extra funding was first reported by Fortune’s Dan Primack.
