Collectionista currently is not a company and I'm not fundraising as such. I however just launched a micro crowd-funding for an Android app on Appsfunder. It's an insanely small investment I'm looking for, but it's something doable and there's a low-risk fast return: http://bit.ly/smecol
Sheet Music Extension for Collectionista will allow you to manage music scores and keep them offline in PDF form on your device. It gets data from http://www.musescore.com. Has a visually stunning presentation.
