Clipboard has reeled in a fresh round of cash for its online archiving service from strategic investor Scientia, money that the Seattle upstart will use to expand into the educational market. It marks the single largest investment in Clipboard to date, though the company is not saying how much it raised.

It adds to the $1.5 million that Clibpoard previously raised from superstar investors in Seattle and Silicon Valley, including super angel Ron Conway; Andreesen Horowitz; Index Ventures; Michael Arrington’s CrunchFund; Draper Fisher Jurvetson; First Round Capital; former Amazon.com board member Blake Krikorian; and Seattle’s Founder’s Co-op

Led by former Microsoft and Yahoo researcher Gary Flake, Clipboard has developed a technology that allows users to clip, save and share sections of Web pages — preserving text, images and links. The service launched last May, and since has grown to more than 100,000 registered users who’ve saved more than 1.7 million “clips.”

Often described as a competitor of Pinterest, Flake addressed that comparison on the GeekWire podcast last year. He called Pinterest “visually appealing” and more “entertainment focused,” noting that Clipboard is much more “utilitarian.”

The joint-venture and investment from Scientia also will help set Clipboard apart.

“Our growth and engagement metrics clearly show that people need to privately save and share items of interest from the Web with one another,” said Flake in a statement. “Moreover, our strategic investment from Scientia validates that Clipboard is on the right path and we will continue offering the best products for saving and sharing the web, privately and publicly.”
