I don't write the marketing copy but I do write the code.

We haven't invented any cryptosystems. What we've built is on top of SSL, HMAC-SHA256 signed tokens and Bitcoin.

What is interesting and novel about our security is our use of brain wallets. The wallets are all literally client-side only. If a user adds a password then no one but them can get at their wallet. Of course, they are still susceptible to phishing, theft and other forms of social engineering, but those are all well outside of the realms of cryptography.
