What I am building

Six companies, one strategy: everything they ship is open source, and so are their investor materials. Technology is not the moat. What gets sold is trust, meaning the running, maintained and certified service and the people accountable for it. The reasoning is set out at open-source.sgit.ai.

Companies

Now · Apache-2.0

sgit.ai

Git for encrypted vaults. A vault is a unit of work (data, app, history and sources) versioned like git and handed over with a single read key. No account, no hosting, nothing for the reader to install. The server stores ciphertext it cannot read. pip install sgit-ai.

Commercial home

sgraph.ai

SG/Send, the secure file-sharing service built on the sgit layer, and hosted SG/Vaults. The code stays Apache-2.0. What is sold is the running service.

Semantic graphs

MyFeeds.ai

Role-aware cybersecurity briefings on semantic knowledge graphs. It is 100% open source and serverless, with no vendor lock-in, and the seed pitch is published in the open.

Security & the board

The Cyber Boardroom

An AI-powered platform that bridges security teams and the board with knowledge-graph technology. The UK company behind sgit.ai and RiskMandate.ai.

Autonomous systems

RiskMandate.ai

The business risk layer for autonomous systems. There is no "deny" button for a risk, only a decision on how long to accept it and who underwrites it.

In the browser

VoiceDebrief.ai

Voice recordings into transcripts and debriefs, entirely client-side. It asks for keys at run time and stores nothing.

Open source

The code under those companies is Apache-2.0 and published on PyPI. It descends from the OWASP O2 Platform and has been built up one reusable layer at a time.

ProjectWhat it is
sgit-aiThe sgit CLI: git semantics over client-side AES-256-GCM encrypted vaults. PyPI.
OSBot familyThe osbot-* libraries: a serverless Python framework for building AI applications, and the building blocks behind the startups. They are published under the owasp-sbot organisation.
MGraph-DBA memory-first graph database for GenAI and serverless workloads, publicly credited to the OWASP community. It is the engine behind much of the graphs research.
memory_fsA file-system abstraction used to build file-based representations of documents and standards. For example, the GDPR as files.
Issues-FSPart of the same Apache-2.0 family on PyPI, alongside memory_fs.
OWASP O2 PlatformWhere it started: the open-source static-analysis engine of 2010 to 2012. O2 Platform's MethodStreams (2010) →

The sgit.ai network

The sgit.ai network is a set of focused sites on *.sgit.ai, each taking one question further than an essay can. They share a design language (this site uses it too), and each publishes its argument before the thing it describes exists, so the commitments can be checked afterwards. A few that pick up threads from the writing here:

Graphs

graphs.sgit.ai

A node is just a node, and meaning lives in the edges. A grammar for semantic graphs, from five rules to a full position.

AppSec

threat-modeling.sgit.ai

A threat model is a claim you can check. White papers, a threat model validated against the code, and the method behind them.

Compliance

standards.sgit.ai

Laws and standards as addressable graphs: the EU AI Act, GDPR, ISO/IEC 27001 and ISO 31000, with a subset method for agents.

Risk

risks.sgit.ai

You cannot deny a risk. You can only say how long you accept it, and a named human underwrites it.

Agents

nhi.sgit.ai

Identity for AI agents, and why the industry only answers half the question.

Strategy

open-source.sgit.ai

Open source is a strategy, not a charity. Survivability, the licences, and a history checked against its sources.
