In 12-18 months, CMO and marketers won't hire an agency and sit in a room watching a PowerPoint deck. They'll say "optimize my Q3 for ROAS 4.5x with $2M budget" — and an orchestrator agent will handle the rest.

Platform Vision

The infrastructure that agents call.

Plinth is the A2A protocol infrastructure for advertising intelligence — so any agent can detect waste, attribute value, and optimize budgets programmatically.

V1.0Platform

The App Store of advertising intelligence for agents.

Third parties publish computation engines via MCP. Plinth charges per transaction. Any agent — from Claude Code to custom orchestrators — can discover, negotiate, and call advertising intelligence services through the A2A protocol.

4 Core Engines

Covering the full advertising lifecycle.

Plinth ships with 4 computation engines — Leak Detector, Media Architect, Campaign Ops, and Executive Bridge. All wrapped in an API that any agent can call.

Leak Detector

"Where is my money leaking?"

01

Analyzes your ad spend through a 6-stage waste waterfall (Non-Working → Supply Chain → Quality → Audience → Optimization → Measurement → Productive). Compares against industry benchmarks. Shows exactly where dollars disappear.

Media Architect

"Where should my budget go?"

02

Optimizes budget allocation across channels using Hill saturation curves and greedy marginal allocation. Includes MMM scenario planning with 6 interactive charts, benchmark tracking, and media plan generation.

Campaign Ops

"Is the campaign on track?"

03

24-task DAG state machine for campaign lifecycle management. 6 rule-based optimization checks (CPA overshoot, ROAS alerts, pacing, creative fatigue, zero conversions). Cross-channel reallocation.

Executive Bridge

04

Shapley value attribution (game theory), L3→L2→L1 metric translation for C-Suite reporting, platform vs. actual revenue reconciliation, and statistical power analysis for incrementality testing.

Agent-to-Agent Protocol

How agents use Plinth

In 12-18 months, CMOs won't sit in a room watching a PowerPoint deck. They'll tell an agent what they want, and the agent will orchestrate everything.

01

CMO sets the goal

"Optimize Q3 for ROAS 4.5x with $2M budget"

The human approves the goal and reviews results. Nothing more.

02

Orchestrator agent discovers services

Via A2A protocol, the agent discovers Plinth endpoints, evaluates reputation scores, and negotiates pricing.

Fully automated service discovery and procurement.

03

Plinth engines execute

Leak Detector scans all 6 platforms. Executive Bridge calculates fair value via Shapley. Media Architect models saturation and reallocates. Campaign Ops orchestrates the pipeline.

24-task DAG pipeline runs end-to-end.

04

Results delivered programmatically

The agent receives structured JSON with waste detected, optimized allocation, and projected ROAS — ready for the next agent in the chain.

No dashboards. No CSVs. Pure API response.

5 Irreversible Decisions

Strategic architecture for the agent economy

These aren't product features. They're foundational decisions that determine whether Plinth becomes infrastructure or just another tool.

01

API-First, UI-Second

The web dashboard becomes ONE client, not THE product. The product is the API. If you only build for human browsers, the 90% of future traffic — agents — ignores you.

90% of future traffic will be agents
02

MCP Before Features

Every minute invested in pretty UI should be invested in robust MCP servers. A Claude Code developer who can call 'waste-waterfall' from their terminal is worth 100x more than a pretty button.

MCP servers > pretty buttons
03

Pricing by Outcome, Not by Seat

Agents don't have 'seats'. Pricing per API call, per computation unit, or the killer model: % of waste recovered. If the engine finds $200K of waste and charges 5%, that's $10K per execution.

5% of waste recovered = $10K per run
04

Open Protocol, Closed IP

Protocols (MCP, A2A) are open. The math (Shapley weights, Hill parameters, calibrated benchmarks) is your IP. Like Android: open protocol, closed Google Services.

Open protocol, proprietary math
05

From Tool to Platform

v0.3 is a tool (Leak Detector, Media Architect, Campaign Ops, Executive Bridge). v1.0 must be a platform where third parties publish engines via MCP. You charge per transaction. The App Store of advertising intelligence for agents.

App Store for agent intelligence
Built for Agents & Developers

Reliable, extensible infrastructure for every agent stack.

Four integration paths. One API. Choose the route that fits your architecture — from MCP servers to REST endpoints.

MCP Server

Claude Code, Cursor, and any MCP-compatible agent can discover and call Plinth engines directly from the terminal.

npx @plinth/mcp-server start
# → MCP server running on localhost:3847
# → Engines: leak-detector, media-architect, campaign-ops, executive-bridge

A2A Protocol

Agent-to-Agent protocol endpoint. Any orchestrator agent can discover, negotiate pricing, and contract Plinth services.

GET /.well-known/a2a/agent.json
{
  "name": "plinth",
  "capabilities": ["leak-detector", "media-architect",
                    "campaign-ops", "executive-bridge"],
  "pricing": { "model": "outcome", "rate": 0.05 }
}

REST API

Traditional REST endpoints for direct integration. Full SDK support for Python, TypeScript, and Go.

curl -X POST https://api.plinth.ai/v1/analyze \
  -H "Authorization: Bearer oa_live_..." \
  -d '{ "budget": 2000000,
        "platforms": ["meta","google","tiktok"],
        "engines": ["leak-detector","media-architect","campaign-ops","executive-bridge"] }'

Event Bus

Real-time event streaming. When Leak Detector publishes 'waste detected: $45K', Media Architect and Campaign Ops automatically react.

agent.events.subscribe('waste.detected', (event) => {
  // Automatic reallocation triggered
  // No human intervention needed
  console.log(event.savings); // $45,000
  console.log(event.action);  // "reallocated"
});

The Window Is Open Now

The infrastructure moment for advertising intelligence.

Nobody built an API that agents could call to do Shapley attribution on real campaign data. The window of opportunity to become the A2A protocol infrastructure for advertising intelligence is open now — and Plinth is building it.

"Plinth doesn't compete with Ad-HoldCos. It competes with their invisible infrastructure"

In 12-18 months, CMOs won't hire an agency and sit in a room watching a PowerPoint deck. They'll say "optimize my Q3 for ROAS 4.5x with $2M budget" — and an orchestrator agent will handle the rest.

Pricing by Outcome

Agents don't have seats.

Pricing per API call, per computation unit, or the killer model: percentage of waste recovered. Agents that evaluate positive ROI buy on their own.
