Founder & Principal Architect
dether.net
Built a one-person, end-to-end delivery capability on AI-native methods, and used it to ship a commercial product. Parallel agent sessions design, plan, build and review under a governance model I wrote: isolated worktrees, harness-enforced worker permissions, and human adjudication at every phase gate.
- → Autonomous research engine (53 tools, 22 sub-agents) that mass-produces evidence-grounded content, and an eleven-phase orchestrator that keeps the monorepo current and documents what it changed
- → The platform it produced, dethernety: open source, graph-native threat modeling on a property graph, with native MITRE ATT&CK, D3FEND and ATLAS mapping and a runtime module ecosystem
- → Agentic architecture coverage: ATLAS as a third framework, five agentic module families with their knowledge-graph slices, and a dedicated agentic analysis served from the BYODt cloud
- → Two interfaces on one core: a browser GUI and an AI coding agent plugin
- → Five deployment editions on one data sovereignty boundary — customer models never leave their own environment
- → AWS cloud behind the first commercial edition, Terraform-defined — serverless identity, subscription commerce, and entitled content delivery
- → Open-core commercial strategy — self-serve subscription alongside compliance-funded enterprise sales under NIS2/DORA, on published pricing
- → Partner channel and financial model — non-exclusive delivery and referral partners, with the customer licence held direct
