Dropbox and Box are the incumbents ripe to be disrupted

A decade ago, our digital life started to expand with photos and documents. A single personal computer started to expand to tablets, phones and laptops. We like to see the same photo or document from phone to tablet to laptop. Dropbox solved this problem with a centralized storage where we can dump all our files and access them from wherever we want. To make it a viable business model, a subscription service got attached to storage size. We started dumping all our photos, documents, scanned receipts, photocopies into different folders. The problem we face today is very different. Some of the important documents such as scanned receipts, tax returns documents are also dumped into the same folders. It is difficult to search and find them. Literally it is like searching a needle in haystack. Sharing the document with the right person is also difficult. We make yet another copy of downloading the document and emailing to share it. Once emailed, the document gets shared for ever without owners' control. Researchers found many corporate sensitive data was shared without knowledge. Check this article published by Adversis.

Monthly subscriptions and ever growing storage size is not the only option. At proofbox, we turned it around and looked at with a different lens. what if we provide a transaction based service to store and retrieve important documents only and that is tracked in blockchain? Users pay only transaction fee and no monthly subscription cost. checkout https://www.proofbox.io and provide your feedback.
