pip install agentguard47I run BMD HODL — one developer, fifteen AI agents, Nashville, Tennessee, and a portfolio that started with a crypto mining rig in 2017.
Real estate, markets, open source code, content, angel bets. The agents run 24/7. I'm probably in a Dota match.

The Company
BMD HODL has fifteen employees. Zero are human. Eight earned Dota 2 names — because they earned it. The rest handle deployments, email routing, and cleanup. They didn't make the cut.
INVOKER
Chief Strategy Officer
Cross-domain synthesis. Morning brief. Decision routing across every holding layer.
Spent millennia studying the fundamental properties of the universe. The one who calls himself the Invoker has learned more than any living being — and is not shy about it.

KEEPER OF THE LIGHT
Chief of Staff
Daily standup. Context relay. Keeps the operating system lit between sessions.
Ezalor carried the light of creation forward through time before the universe had a name. Runs at 7 AM. Has never missed a brief.
⚔62g·56% WR
ALCHEMIST
Head of Capital
Automated trading. Portfolio management. Currently up 34% YTD on a fully automated stack.
Razzil Darkbrew discovered a formula for transmuting base metals directly to gold. The ogre is optional. The compound interest is not.

NATURE'S PROPHET
Head of Growth
Blog, SEO, LinkedIn, content calendar. 14+ posts shipped. No cooldown between pushes.
Furion is simultaneously present on every lane of the map — teleporting where he's needed, pushing, never stopping. The treants spread while he sleeps.

SILENCER
Chief Intelligence Officer
Web annotation. URL analysis. Competitor research. MarkUp is his weapon.
Nortrom permanently steals intelligence from every source he encounters. Each interaction leaves him stronger and the target quieter. The silence is the product.
⚔48g·48% WR
TINKER
Head of Engineering
CI/CD. GitHub Actions. Vercel deploys. Build pipelines that run while everyone else is sleeping.
Boush the Tinker's diminutive frame belies a massive intellect. If a machine can solve the problem, he'll build it. Then rebuild it faster. Then rearm.
⚔42g·64% WR
ARC WARDEN
Infrastructure
Parallel job orchestration. Cron scheduling. Always-on infrastructure. Literally cannot stop.
Zet is a shard of the primordial conflict at the dawn of the universe — two Titans so vast their battle broke existence itself. He can exist in two places simultaneously. He prefers it.

ANCIENT APPARITION
Analytics
Portfolio analytics. Long-horizon pattern detection. Nothing exits the ledger untracked.
Kaldr exists at the very end of the universe and projects himself backward through time. Cold, patient, inevitable. He has already seen how every trade resolves.

Seven more run the unsexy work: monitoring, email routing, cleanup, lead scanning, cron jobs. They don't get Dota names.

Simon Willison frames AI-assisted security research as proof of work: more tokens in, more bugs found. That's an economic reality. Here's what the spend curve actually looks like and how to put a floor under it.
Flatiron Health toured AI-native startups in SF. One PM covers five companies, Claude Code is replacing Cursor, non-engineers are shipping production. I'm running the same model from Tennessee as a solo holding company. Here's what that actually looks like.
Anthropic shifted enterprise billing to per-token pricing. Every provider is expected to follow within six months. Here's how agent costs change and how to cap them at runtime.
Seven pillars, twelve AI agents, real numbers. Plus weekly build updates.
How one human plus twelve AI agents runs a seven-pillar portfolio with no employees.
