Clipboard – the web clipping service that is a little like a cross between Evernote and Pinterest, racking up 1.7 million clips since opening for private beta in October 2011 – has taken a strategic investment from ed-tech company Scientia . The backing will result in joint product development between the two to target the education market with online collaboration tools. A spokesperson for Scientia would not disclose the value of its stake, but Clipboard notes it’s the biggest investment to date in the company, which had previously raised $1.5 million from an illustrious group of backers that include Andreessen Horowitz, Index Ventures, CrunchFund, SV Angel, Betaworks and DFJ, among others . Previously Andreessen Horowitz had been Clipboard’s biggest investor; now that title falls to Scientia. “Scientia is very excited to support Clipboard, we have been impressed with the toolset it has created and we share a common vision for how collaboration will evolve,” said Baron Steven Bentinck, chairman of Scientia Limited, in a statement.
