Cold Outbound Ventura ADU
— per-customer Mac minis

Four California laws signed in 2025 took effect this year. ADU demand is spiking. Builders are scrambling for pipeline. None have sophisticated outbound. The category-defining gap: no local competitor offers AI-driven cold outbound to ADU builders.

This is the most important diagram in the portfolio. One Mac mini per paying customer. Plus one operator Mac mini at the top. All connected via Tailnet. Per-customer isolation is not optional — it's the reason this business model works without catastrophic deliverability or compliance failures.

Same 5-agent pattern as the rest of the portfolio. What changes per project is the skill bindings — what each agent actually does. Below are the skills the PRD binds explicitly for this project.

Each customer Mac mini exposes its own four channels. Builder-side comms run via Telegram + Dashboard; prospect-side comms run via Email + SMS (with Website Chat for the customer's own dashboard interactions).

Three tiers. Each gets its own Mac mini regardless of tier — the difference is volume + channel coverage. Setup fee covers initial provisioning. Optional 2% performance bonus on closed deals attributable to campaigns.

The repeatable per-customer onboarding. Every paying builder goes through this exact sequence. By Month 3 of operations, agent automation should compress operator time to under 2 hours. Months 1–2 are slower while the playbook is being calibrated.

Every new customer's sending domain takes 30 days to ramp from zero to full volume. Skipping this is the fastest way to destroy deliverability. The curve is conservative on purpose — engagement metrics gate progression to the next step.

Replies aren't just yes/no. The Marketer Agent classifies every inbound into five buckets. Each bucket has a different handling path. Hostile replies always escalate immediately to the operator.

Sales is the bottleneck in Phase 1. Builder customer #1 has to sign before infra investment is worth it. Phase 2 proves the funnel. Phase 3 is the scale ramp. Phase 4 is market saturation + first vertical expansion.

11 risks. Three are existential: R1 (deliverability collapse), R2 (customer-imported bad list), and R3 (TCPA lawsuit). R5 (LLM cost) is the most likely day-to-day grind. R11 (off-boarding) is treated as a feature, not a risk — plan for it from Day 1.

Six core entities. BuilderCustomer is the root; everything else (Campaign, Prospect, Message, etc.) is per-customer scoped. SuppressionList is dual-scoped — per-customer plus a global suppression list shared across all customers (anyone who opts out anywhere is opted out everywhere).

Two weeks because Cold Outbound requires building infrastructure to repeat the customer-onboarding workflow, not just standing up one site. Days 1–7 are the operator Mac mini + crawlers + compliance tooling. Days 8–10 are the first customer's onboarding.

Unlike the pilot, every aspect of Pro tier applies here. This is the textbook archetype.

When a builder customer leaves, their Mac mini and everything on it transfers to them. This is a feature, not a failure mode. It's the moat for retention (we make it easy to leave, so they don't fear the lock-in) and the responsible-exit story for legal/insurance counsel.

Cold Outbound is the cash engine of the Ventura Trifecta. It funds others. It also shares the most reusable infrastructure: the Ventura crawlers, CSL verifier, and CEO Agent sales skills transfer across the whole portfolio.

Terms specific to this project. Note that customer and tenant mean different things in Cold Outbound vs Website Landlord — careful when cross-referencing.

Builder / Customer

Our customer. An independent ADU builder paying us monthly for outbound campaigns. Gets their own Mac mini.

Prospect

Our outreach target. A Ventura County homeowner we email or SMS on the builder's behalf. Hasn't opted in — compliance carries every send.

Lead

Our deliverable. A prospect who replied positively and got qualified into a meeting on the builder's calendar.

ADU

Accessory Dwelling Unit — a secondary dwelling on a residential property. California has aggressive pro-ADU laws since 2020 and four new ones for 2026.

JADU

Junior ADU — capped at 500 sq ft. AB 1154 (2026) removed owner-occupancy requirements if separate bathroom.

SB 543 / AB 462 / AB 1154 / SB 9

The four 2025-signed California laws driving 2026 ADU demand. SB 543 = no school fees on small ADUs. AB 462 = 60-day Coastal permits. AB 1154 = JADU rules. SB 9 = lot splitting.

CAN-SPAM

Federal email law: unsubscribe link, sender ID, physical address required on every commercial email. Engineer Agent enforces at send time.

TCPA

Telephone Consumer Protection Act. Governs SMS. Requires documented opt-in for every recipient. Penalties are per-message — six figures fast if violated.

CCPA / CPRA

California consumer privacy regs. Data subject access requests handled within 45 days. Relevant because all prospects are California residents.

DNC

Do-Not-Contact list. Federal, state, and per-customer scoped suppression lists must all be honored before any send.

Warm-up

The 30-day domain reputation ramp from 50 → 300 sends/day. QA Agent gates progression on bounce/spam/reply metrics. Never skip.

AI Receptionist

The GHL AI Employee that handles inbound prospect replies — qualifies and books meetings. Backed by Sonnet for reasoning, Haiku for routing.

SOC 2 Type 1

Compliance audit some builder customers will require before signing. Target: complete within 6 months of first paid customer.

Performance bonus

Optional 2% of closed deals attributable to a campaign. Often exceeds monthly retainer. The alignment-of-incentives lever.
