THE "B" WORD, (AGAIN): Education Week is the latest to hop in the bubbly bathtub, echoing concerns raised by Frank Catalano back in October that investment money may be flooding to ideas that have neither educational value nor viable business models. However, investment tracker CB Insights begs to differ. "There Is No Ed Tech Bubble," it solemnly states. Of the estimated $1.1 billion of financing in 2012 from VCs, angels, corporation and private equity investors, 70% went to seed/angel and Series A deals, which it apparently sees as "pocket change in the grand scheme of things." And the possibility that edtech startups won't be able to follow through with later rounds "is a sign of a market that is actually working."
