The Autonomous Marketing Harness

One marketer and a swarm of agents booked 33 meetings across 5,260 target accounts in a few weeks.Here is the whole engine.

Harness = ledger · coded gates · human below the bar

• Ledger: every touch written before it goes out.
• Gates as code: rules in advance, not vibes in the prompt.
• Confidence bar: above the bar it runs. Below the bar it asks.

• The brain: a frontier model, plus your playbooks, context and rules.
• Eight agents execute, one per channel, from intent to ads.
• Your team keeps the judgement calls. Sales still takes every meeting.

• 5 came through the gift and email play. The other 28 came through social outreach, pure outbound and ads.
• 8,915 people reachable out of 16,257 found, every address verified.
• It enriches, verifies, drafts and queues on its own, and hands me five decisions a day.

• Each page names the person, with their brand, audiences and ads.
• Built by metadata.io MCP tools: on brand, hosted, no agency.
• The film pipeline underneath: Kling, Fal.ai, FFmpeg, Gemini for review.

The tools

• Sense: the target list from one skill, plus G2, Bombora, web and CRM.
• Decide: a frontier model, checked by a twelve-model council.
• Act and learn: 25 skills, every touch logged, gates rewritten as code.

• One touch a day per account: a gift, an email, a note or an ad.
• Pages and films: metadata.io MCP, on brand.
• Two outcomes are theirs: the meeting, then pipeline.
