Bubbles a Web-based email platform that lets users create and send handwritten notes over email has received $100,000 from angel investors, including a former Adobe engineer. The service is currently in beta but has already signed up 40,000 users. Using the platform, a consumer can write a note or draw an image using a virtual piece of paper and then send the file as a PDF email attachment. The angel funding will be used to continue development and marketing of the product.
