Throwing my "I <3 Keybase" comment in the ring while doing some brainstorming here.
It seems to me that there's a lot of product opportunities in the corporate world that go beyond what Keybase is providing today. Chat and Git are interesting, but there's already a lot of momentum in both these areas. Been thinking how I use encryption and where things fall short today. One of those areas is build signing and hardware key management for our team.
Everything that goes on our servers get signed by an official PGP key. Only a couple people can sign builds, and each has a Yubikey with PGP subkeys on it. This is kind of annoying to manage. We use an airgapped computer that houses the private key, can create subkeys and assign to Yubikeys, can handle expiration management, etc. When we want to deal with this, we have to get the computer, unlock access, and deal with the command line. This is error-prone and annoying. Having a solution that allows for safe storage of a private key and easy management of subkeys on smartcards would be amazing without the need for an airgapped computer and a command line would be really interesting.
(The signing/verification part can probably be handled today by the keybase tool.)
Okay, that's maybe more specialized. Let's move away from paranoid server builds and go toward something similar that's gotten plenty of companies in trouble: Malicious e-mails. How often are we hearing about some poor employee receiving an e-mail that appears to come from a co-worker that contains a finance document with a trojan? Or maybe just a simple document with a form, instructions, and a link that results in information leaked to some third-party?
If there was a dead-simple way to sign and validate documents over Keybase (and I mean dead-simple, built for people who only know Word and Excel), for use in e-mail and document management, with marketing around "For $XX/user/month, you don't have to worry about getting hacked," I bet plenty of companies would bite.
I don't know what that looks like exactly, but just playing around loosely with some thoughts, it would be interesting (particularly for fully IT-managed systems) to have a Keybase Shield product that would automate much of the signing and verification of documents. It could tie into Word, Excel, etc. via their plugin interface and sign on save, and/or provide a big "Sign this document" widget on the side of the screen that a document can be dropped onto (or a Share action on phones). It'd then own the file associations for these documents, intercepting them when opening via e-mail or file servers, and would validate their signature. A document from the outside world (or one not going through the corporate-mandated signature process) would outright fail to open with an error message and instructions to ask the sender to please sign the document.
(Lots of details to work out there, but if this process could be made simple and mostly automatic, you'd help close a major attack vector that companies are susceptible to today.)
Anyway, it's great hearing your thoughts on how Keybase plans to make money. I've been in the same boat of loving Keybase but being uncertain about where it'll be 5 years from now. We'll keep an eye open for some paid products :)
On the document management end of things: that's exactly what the public/yourname/ subdirectory of KBFS is-- every document there gets signed when edited, then they're automatically verified (by the KBFS client) when someone tries to download them (either the original author, or another Keybase user).
There's no explicit signing process involved, but that's part of Keybase's value proposition: automatic and transparent public key cryptography.
If you can tie the shield into KBFS, that's even better. It's not enough to protect a company from attacks, though. People may still click that random document coming in via e-mail that claims to be from a co-worker. A mandatory technical solution on that end, no matter what the actual technology looks like under the hood, would be essential for protecting people from making these kinds of mistakes.
The value proposition of automatic and transparent public key cryptography is strong, and what I love about Keybase. Just thinking of other ways that can be applied transparently.
A team-based 1Password-type service would also be interesting, particularly one allowing heavy use of 2-factor authentication with something like a Yubikey.
