About Threenine
Our mission
Threenine builds products for identity, signing, publishing, and digital sovereignty.
We believe the next generation of internet software should give users more control, not less. That means building systems where identity is portable, private keys stay under user control, publishing is less dependent on gatekeepers, and products are shaped around open protocols instead of platform lock-in.
Why we exist
The old internet model is built around centralised control, surveillance, data hoarding, and weak user ownership. That model is still dominant, but it is no longer the only option.
Open technologies such as Bitcoin and Nostr create a different foundation. They make it possible to build products where users have stronger control over identity, communication, payments, content, and trust relationships.
Threenine exists to help drive that shift forward through real software.
What we build
We focus on products and product infrastructure connected to:
- identity and account control
- signing and consent flows
- publishing workflows
- privacy-sensitive product design
- Bitcoin-aligned and Nostr-native software
- digital sovereignty tools and experiences
Our work is guided by a simple rule: software should help users hold more control over their identity, data, keys, and relationships, not quietly take that control away again.
How we work
We are product-led first.
That means we do not approach this space as a generic software consultancy looking for interchangeable contract work. We build our own products, learn from real implementation constraints, and bring that experience into focused engineering support for aligned teams.
When we work with clients or partners, we are strongest where the work involves:
- Nostr product development
- Bitcoin product development
- signers and approval flows
- browser extensions
- publishing systems and creator workflows
- privacy-sensitive UX and trust-aware product behaviour
What we believe
We believe:
- users should have stronger control over their digital identity
- private keys should remain under user control
- publishing should not depend entirely on closed platforms
- products should be honest about trust boundaries
- open protocols matter most when they are made usable in practice
- digital sovereignty should be a product reality, not just a slogan
Company direction
Threenine is not trying to be a generic agency with protocol-flavoured marketing.
We are building a product company with serious capability in Nostr, Bitcoin, identity, publishing, and privacy-sensitive software. Services exist as a secondary layer for teams that want help from people already working directly in this space.
Looking ahead
The long-term opportunity is bigger than any single app or integration.
We want to contribute to a better software ecosystem, one where people can communicate, publish, pay, and participate online with stronger ownership, clearer consent, and fewer platform dependencies.
That is the direction behind the products we build and the engineering work we choose to take on.
