Mobile-based shopping aggregator Sift has announced closing its seed funding with an additional $1.5 million raised, bringing the company's total seed funding received to $2 million.

Sift received the new funds in an investment round led by DN Capital, according to published reports; the funding also included previous investors including the Sand Hill Angels, Unityu Venturs, and Tandem Capital.

Sift uses a scan of marketing emails in user inboxes to create an 'e-commerce fingerprint' which helps the company create a personalized shopping browsing app available on the iPad and iPhone.
