Many companies work closely with other companies. Retailers and suppliers joined at the hip. Startups and overseas outsource dev teams. The list goes on. You get the idea.
Cross-company social is hard right now—hence it's all mostly still email. Sure you can set up Slack Connect and whatnot, but that's relying on both companies using Slack—and that's also empowering Slack itself—and regardless one company in the mix will always "own" the channel, and that's not fair.
With Nostr, you can set up a cross-company Kind1 social space just like good-old email. Excuse the took-two-minutes fig-jam screenshot here and use your imagination to expand it to multiple companies interacting with multiple other companies in a very nostr-like web. (Or potentially siloed-off departments of the same parent company interacting with each other.)
The Nostr relay system comes into play because every company needs to maintain its own relay(s), and there can be separate relays for different departments (marketing, IT, sales, etc.), all duplicated on either side of the fence. It's almost like Nostr was accidentally made for this.
Key-paris are great because many front-line workers (drivers, security, etc.) don't have SSO pathways. An employee exposed their nsec? Who cares, have the IT person pop a new nsec into that person's Google Workspace profile custom field and the NIP-05 list plus relay filters will update—these are all gated relays, the relay is king, the whole eternally-vexing key management thing is suddenly a non-issue. Non-relay-whitelisted keys become useless.
And the whole "can't delete", "can't edit" thing? Again, it becomes a non issue. When you send an email to Company B can you delete or edit it? No. You can ask them nicely, that's all. Companies just have to educate employees to view cross-company social posts like emails, and that's not hard for employees to understand. This whole thing is just fancy email after all (but still very much needed).
And the whole spam thing? There's no spam. These relays are not open to the wide world.
And the whole "I can't find my community" issue? The community is already there, included in the box, like a phone charger.
PLUS this is all pure Kind1 stuff. Companies chatting with each other across bespoke implementations of Kind1 clients. The dev work on those has mostly been done, the client and relay code is there and open source and MIT and all. What's needed (and what my team is focussed on, perhaps other teams too) is old-fashioned B2B sales and systems-integration support, like Red Hat in the early days, take all the Linux stuff that's out there and support companies to integrate it, help IT teams tweak it, own it, run it (and in doing so eventually become a key contributor to the codebase yourself).
This cross-company market alone is massive. Really massive. Onboard a pair of companies with 1k employees each and that's already an incremental bump in global Nostr usage (albeit one that would be off the nostr.band radar).
And this cross-company Kind1 social is just one example. Many other examples.
Again I get that Nostr wasn't invented for B2B but boy oh boy could the business world ever come to love it.
