4NK — Self‑Custodial Cloud OS
Safer, simpler, sovereign, and inexpensive.
What’s the problem?
The cloud market is dominated by permissioned and vulnerable third‑party solutions. Users pay increasingly high rent to someone to manage their identities and access their own data, while facing hacks, ransoms and surveillance. Digital sovereignty is a well‑understood requirement, yet everyone pays the price of simplicity at their own expense. Every time we click “accept,” we reinforce economic, security, and policy dependency. What if the solution was in our own hands?
How to fix this? — Manifesto
We want to own and manage our logins, sharing, payments, messages, and identity without passing through central servers or leaking metadata. We want to handle it all directly on and from our devices.
- No CAPEX, no data centers required
- Each user is a building block of the infrastructure
- Every flow is a cryptographic proof
- Every action is a verifiable validation
We want digital sovereignty to be a technical reality, not a third‑party promise.
Introducing the Self‑Custodial Cloud OS
An app to rebuild the web—upright:
- Identity: users own and manage their keys
- Security: distributed and fully encrypted storage
- Infrastructure‑less: leverage existing underused devices (laptops, servers)
- Network layer: distributed and open; islands of nodes
- Proofs at every step: verifiable and anchored in Bitcoin
- Third‑party dependencies: none
- Open‑source
No blockchain and no token: a client‑side infrastructure that extends Bitcoin’s properties for everyday use.
What can we do with it?
- Personal sovereignty: secure document storage and sharing; “100% local” LLM on user content
- Collaborative: P2P secure messaging (no central server, no metadata leakage); secure document workflows (encrypted storage and sharing, simple identity management, timestamped proofs at every step); discovery and publishing of “contracts”; payment layer
Bitcoin under the hood
- Secure messaging with an embedded Bitcoin wallet in the browser using silent payments for secure and metadata‑less messaging
- Log in with one scan: native Lightning support (no Stripe, no PayPal)
- Records and actions are timestamped on Bitcoin L1 (a few bytes/day)
How it works
Super‑simple user experience:
- Lightweight background app turns existing, often‑idle equipment into a node
- 100% browser‑based UX to interact with the node, locally or remotely, for owners and invitees
- Log in with one scan, 2FA options, multi‑sig, including phone enrollment
- Secure messaging layer with no metadata leakage
- “Chat‑first” experience (roadmap)
Networks
- Every user is a building block of the new infrastructure
- Professional islands and opt‑in to larger networks (forming Layer 2s)
- Scale‑out, small or large
Disrupting a huge market
The cloud and collaborative market is dominated by GAFAMs, a TAM of $250B. “Under‑the‑radar” SAM is about $80M. Beyond 2030 ambition: $3–5B (≈2% of the market).
Status
- Main software development: done
- $500K revenue from paid POC customers over the last 24 months
- Pipeline: 5–10 prospects from SMBs to Tier‑1 operators (Orange, Docaposte), sales cycle evolving
- Pre‑production white‑label service targeted to French Notaries
- Soon to launch: DOCV.fr (B2C2B freemium)
What’s next?
Pre‑series round: raise $500K from strategic, supportive partners.
Key objectives include GTM kickoff (sales/marketing, PLG motion), profession‑centric deployments (notaries, lawyers, family offices, local public branches, health), white‑label distribution (convert Tier1/2 POCs), opportunistic SMB workflows, feature iteration toward PMF and international reach, and reaching break‑even with $1M ARR to enter Series A in under 15 months.
$100M ARR in 5 years is feasible.
