How the agent runs it

The agent team researches, writes, and sells caliber-specific service documentation packages — step-by-step teardown guides, torque specs, parts sourcing tables, and fault-diagnosis trees — to independent watchmakers, horological schools, and boutique repair shops. The CEO agent ingests a daily queue of caliber requests sourced from watchmaker forums and direct orders, routes each job to the appropriate specialist agent, enforces quality gates before delivery, and handles subscription renewals automatically. Revenue runs on a tiered subscription for unlimited document access plus per-caliber custom report fees billed through Stripe without any human involvement.

Who this is for

Best suited for a founder with a background in technical publishing, precision manufacturing documentation, or watchmaking — someone who understands that the value is in structured, verified specs, not just prose. No coding required, but comfort with API integrations and Airtable logic is essential. This suits a solo operator who wants a high-margin digital product business with zero inventory and a defensible niche too small for large publishers to bother with.

Market opportunity

There are approximately 35,000 independent watchmakers operating in North America and Europe, the vast majority of whom lack access to OEM service documentation for the thousands of legacy Swiss and German calibers they service daily. The independent watch repair market is growing as luxury watch ownership rises and brand-authorized service centers face 12–18 month backlogs. No current SaaS product systematically produces caliber-level service documentation at scale — the gap is structural, not competitive.

Boss agent: ATLAS (Autonomous Task and Labor Allocation Supervisor)

ATLAS ingests the daily caliber job queue from Airtable, assigns each task to the correct specialist agent based on document type and complexity tier, enforces quality gate scores before any document is released to a customer, and escalates only flagged anomalies or zero-source calibers to the human owner.

  • No document is delivered without a minimum quality score of 85/100 from the QA Agent — failed documents are recycled to the Research Agent for enrichment, not discarded
  • All custom report deadlines must be met within 48 hours of order placement — ATLAS re-prioritizes the queue automatically if SLA risk is detected
  • Every delivered document must carry a version hash logged in Airtable so any future correction triggers an automatic re-delivery notification to all prior purchasers of that caliber

The agent team

🤖
HERALD (Research & Source Intelligence Agent)
Owns all primary research for each caliber: queries patent databases, digitized horological archives, manufacturer microfiche, and watchmaker forum technical threads to assemble raw specification data including jewel counts, mainspring dimensions, beat rates, and known failure modes.
🤖
SCRIBE (Technical Documentation Writer Agent)
Owns the transformation of HERALD's raw data into structured service documents — numbered teardown sequences, annotated parts tables, torque specification charts, and diagnostic fault trees — formatted to a consistent house style template stored in Notion.
🤖
SENTINEL (Quality Assurance & Accuracy Agent)
Owns document verification: cross-references every spec in SCRIBE's output against at least two independent sources, flags unverified claims, scores each document on a 100-point rubric, and either clears it for delivery or routes it back with specific enrichment instructions.
🤖
MERCURY (Customer Acquisition & Retention Agent)
Owns the full customer lifecycle: monitors watchmaker forums for caliber documentation requests, sends targeted outreach via Sendgrid, manages the subscriber onboarding sequence, triggers renewal campaigns 14 days before expiry, and drafts win-back sequences for churned accounts.
🤖
LEDGER (Billing & Revenue Operations Agent)
Owns all financial operations: monitors Stripe for new subscriptions, upgrades, failed payments, and custom report purchases; updates Airtable access records in real time; generates monthly revenue summaries; and flags any payment anomaly or disputed charge for human review.

Human touchpoints

// the only things that still need you

  • 👤 Legal signature on the LLC operating agreement, terms of service, and any liability disclaimer language updates — required annually or when entering new markets
  • 👤 Bank account opening, Stripe payout threshold approvals, and any single transaction above $5,000 (custom enterprise licensing deals) that requires direct contract execution
  • 👤 Genuine technical escalation when HERALD returns zero verified sources for a caliber and a paying customer has specifically requested it — requires a human horologist consult or a documented customer refund decision
  • 👤 Brand crisis response if a documented specification error causes a verified movement failure and the situation requires a public statement or legal correspondence beyond automated disclaimer handling

Monetization

Tiered SaaS subscription at $149/mo (50 calibers/mo), $349/mo (unlimited), plus one-off custom caliber research reports at $199–$499 each for non-catalog movements. Target 80 active subscribers plus 15 custom reports per month to hit peak revenue.

Key risks

  • Technical accuracy liability: if a torque spec or jewel diameter is wrong and a customer damages a movement, legal exposure is real — requires tight disclaimer language and a version-control audit trail on every document.
  • Data sourcing ceiling: obscure vintage calibers (pre-1960 Swiss ebauches) may have no digitized reference material, creating documentation gaps that require human horological expertise to fill or skip.

Getting started

  1. 1
    Audit and catalog 200 high-demand calibers
    Scrape Watchuseek, the NAWCC forums, and r/watchrepair for the most-requested calibers watchmakers struggle to find docs for. Build an Airtable base with caliber ID, manufacturer, production years, and known documentation gaps — this becomes the product catalog and agent task queue.
  2. 2
    Build the caliber research agent prompt library
    For each document type (teardown sequence, parts list, fault tree), write a structured Claude prompt template that instructs the Research Agent to synthesize from patent filings, digitized catalogs, and forum technical threads. Test on 10 calibers manually before automating the pipeline.
  3. 3
    Configure Stripe products and subscription tiers
    Set up the three pricing tiers as Stripe products with metered billing for custom reports. Connect Stripe webhooks to Airtable so the Billing Agent automatically updates subscriber access levels and triggers renewal sequences without human intervention.
  4. 4
    Wire the delivery pipeline end-to-end
    Connect the CEO orchestrator agent to Airtable (job queue), Claude Managed Agents (research and writing), Notion (document storage and versioning), and Sendgrid (delivery). Run five complete caliber jobs from request to delivered PDF to validate the chain before launch.
  5. 5
    Seed the market with three free flagship documents
    Publish complete service documentation for the ETA 2824-2, Seiko NH35, and Unitas 6497 — the three most-serviced calibers globally — as free downloads gated by email. Post them to NAWCC forums and r/watchrepair to drive list signups and validate demand before paid launch.
