Helperbit is an Italian startup that uses blockchain technology and Bitcoin to bring transparency in charity sector and to offer an innovative insurance solution against natural disasters. In charity sector there are problems related to inefficiency, opacity and bad administration of funds, that lead to a lack of trust in non profit organizations. The insurance system related to natural disasters faces similar problems, due to complex refund processes, long bureaucratic procedures and lack of trust in insurance companies. Helperbit developed a donation transparency platform where people can donate directly to NGOs for generic causes or to public entities involved in the emergency relief, tracking the donations in real time and monitoring the use of funds thanks to blockchain. Helperbit also offers a mutual, parametric and p2p insurance service that covers collateral damages caused by natural disasters. The redistribution algorithm is transparent and fair, while the refund is fast and automatic.
