## Pages
- [Home](https://crisgrossmann.com/): the workbench — 11 AI systems he runs (The Swarm,
  MoneyLake, HealthPane, AI Race Engineering, Home Cooker, In the Chair, more),
  with real, verified numbers. Primary offer: one-to-one AI training for CEOs
  and board members. Also: build, train a team, speak.
- [AI Training](https://crisgrossmann.com/ai-training/): one-to-one AI training for
  CEOs and board members — 1:1, in their work, not in a deck. They leave
  working differently; AI working for them. Online or in person. Covers the EU AI
  Act Article 4 AI-literacy obligation in force since 2 February 2025.
- [Notes](https://crisgrossmann.com/notes/): index of building notes, with RSS.

- [PCI, 1999](https://crisgrossmann.com/pci/): a recovered 28 KB zip — 823 lines of
  Java, raw UDP sockets and six text files, built at 17 for a five-person office
  in Mexico City. The data model is the one behind fourteen years of Beekeeper.

- [Jini, 1999 → the house, 2026](https://crisgrossmann.com/jini/): Sun's Jini spec
  on disk in December 1998, scored against a real house in 2026 (1,702 entities,
  134 devices, 44 integrations). Three of six promises won. Three lost.

- [Story](https://crisgrossmann.com/story/): full arc Mexico City → ETH Zurich
  (PhD, ETH Medal) → Beekeeper → exit → back at the bench.

- [The Orchestrator](https://crisgrossmann.com/orchestrator/): the full build of The
  Swarm — twelve headless AI agents on a Mac, two Postgres lakes (health: 3,778
  sessions and 8,590 nights since 2012; money: 16,094 transactions),
  one coached brief every morning at 07:30. Replaced five subscriptions worth USD
  3,720/year. Agents are markdown files, not code; the model is a component, not the architecture.

- [AI Race Engineering](https://crisgrossmann.com/race-engineering/): his AI head
  coach on 14 years of telemetry — sealed a race prediction publicly, missed the
  total by 1:53 but called the decisive bike split to 4 seconds; closed the gap
  to the age-group podium from 4:34 to 71 seconds across two races in seven days.

- [The Health Lake](https://crisgrossmann.com/health-lake/): 3,778 sessions, 8,590 nights,
  75 races since 2012. Resting HR fell 54.6→46.7 bpm; a 353-consecutive-week streak;
  one honest null result (sleep duration does not move his HRV).

- [The Race Ledger](https://crisgrossmann.com/race-ledger/): all 75 races since
  2012 with field percentiles — from the 77th percentile (2012) to the top 6% (Uster, Aug 2026).

- [The Life Grid](https://crisgrossmann.com/life-grid/): 40,423 calendar events
  since 2011. Meetings 3.4 → 28.8 → 6.0 h/week. Meeting load correlates with
  overnight resting heart rate (r = +0.44).

- [Anatomy of a Ledger](https://crisgrossmann.com/ledger/): 16,094 transactions,
  97 accounts, 2,284 payees. Five structural findings, no balances published.
  The discipline recovered CHF 6,200.
