Great questions! I've answered them below and am happy to expand if needed.
Who is your target demographic? -
Our target demographic is males between 20 and 50, mostly because that's the value majority of crypto users. A smaller subset of that would be lighter blockchain users, just starting to explore the space.
How is this better than a paper wallet? -
Gridlock is better than a paper wallet because each storage device is not critically important. If your paper wallet is lost, destroyed, or stolen, then you lose everything. With Gridlock, the loss of any single (or even multiple) storage devices does not affect your stored assets. If someone can compromise your storage device, they get nothing unless they can compromise multiple devices...on different platforms...in different parts of the world.
What happens if Gridlock disappears? -
If Gridlock disappears, you will have to collect encryption keys from your storage devices manually. The security of the product remains intact with or without Gridlock. The initial product uses a centralized communication layer because decentralized communication is tough, and we decided to focus on security over the very small chance of a service outage. That said, the move to a decentralized communication layer is on our roadmap. Once complete, the system will be secure and 100% available without Gridlock servers.
Do you have plans for a security audit? -
Yes, do you have suggestions on the best company?
Where's the code? Is this going to be open-sourced? -
Yes, the code will be open-source and available once we release it. We don't want people judging our mess while we are under construction. :)
How are you going to make money? -
The core product will be free for life. We are looking to monetize with premium value-add services as well as commercial use licenses.
Who are your direct or close-enough competitors? -
Argent is a good comparable that provides enhanced security with built-in usability. Unfortunately, they can only support Ethereum+. Trezor does have key sharding capabilities (I use this personally). However, it is very much a recovery-only solution, and it's not very usable (much like the rest of Trezor's model). For example, if you don't have physical access to your Trezor, you can't do anything. This restriction isn't great, and I have a painful recent experience with this in particular. cough SEC and XRP over Christmas cough
