Bhathena and other Ziptr staff did not immediately respond to requests for comment.
This doesn't sound a whole lot different from any other un-graceful startup shutdowns. Did this service have a lot of users?
Also, is the characterization of Ziptr as an "encryption provider" accurate? Or were they just a secure document storage company? There are a lot of companies that do "document encryption" and "email encryption" for enterprises that are not, as HN privacy enthusiasts understand the term, really crypto products.
