We missed this one earlier: Incubator Curious Office has closed its first round of funding of $1.7 million for its latest venture, Pressplane, led by Second Avenue Partners and angels, including *MTVN’s* Mika Salmi, Expedia founder Rich Barton, former Expedia CEO Erik Blachford, Whitepages founder Alex Algard and a slew of others. In its announcement, the company was vague on the details as to what Pressplane is, but says it is a “buy and sell marketplace” similar to art images site Imagekind, but geared towards designers and creative content serving businesses.

The Seattle-based incubator started in 2005 and has four other companies in its portfolio, such as book-focused social net Shelfari, which Amazon acquired just last month; Fanzter, which launched product site CoolSpotters this year; tool developer SEOmoz; social shopping service Wishpot and RSS toolbox FeedDigest.
