HubSpot Deal-to-Marketing Attribution Agent
AI-powered monthly deal-to-marketing attribution — AI-reasoned multi-touch attribution, campaign effectiveness, content impact, channel interaction synergy, and dark funnel detection.
Reconstructs marketing touchpoint timelines for HubSpot closed-won deals monthly. Uses AI reasoning (not algorithmic first/last/linear) to attribute revenue to channels with explanations of WHY each channel mattered. Identifies campaign effectiveness, content that sells, multi-channel synergy effects, and dark funnel deals with minimal trackable touches. The CMO budget allocation tool. Notion attribution report + Slack executive summary. 27-node n8n workflow with monthly scheduler. BQS 12/12 certified.
Four Agents. Monthly Attribution Intelligence. CMO Budget Tool.
Step 1 — The Fetcher
Code-only
Retrieves closed deal data and associated marketing interaction history from HubSpot API for the current and prior months — deal value, close date, contact timeline events, campaign memberships, form submissions, email clicks, page views, and UTM parameters. Pulls multi-touch interaction sequences for attribution modeling.
Step 2 — The Assembler
Code-only
Computes 5 attribution dimensions: channel attribution (revenue credited to each marketing channel using first-touch, last-touch, and linear models), campaign effectiveness (revenue per campaign with ROI estimation), content impact (which content assets appear most in winning deal paths), interaction effects (multi-touch sequence patterns that precede closed-won), and dark funnel detection (deals with no attributable marketing touchpoints).
Step 3 — The Analyst
Tier 2 Classification
Analyzes attribution data for budget optimization insights: which channels deliver highest revenue per dollar, which campaigns over- or under-perform, which content should be scaled, what multi-touch patterns to replicate, and how large the dark funnel is. Generates budget reallocation recommendations with estimated impact.
Step 4 — The Formatter
Tier 3 Creative
Generates a Notion monthly attribution intelligence report with channel revenue tables, campaign ROI rankings, content impact analysis, multi-touch journey maps, and budget recommendations, plus a Slack digest with top 3 budget optimization actions.
What It Does NOT Do
Does not modify HubSpot deals or contacts — read-only analysis of marketing interactions and deal outcomes
Does not replace dedicated attribution platforms — it provides monthly intelligence from HubSpot data
Does not integrate directly with ad platforms — it uses HubSpot-captured UTM and campaign data
Does not automate budget changes — it recommends reallocations for human decision-making
Does not solve multi-device or cross-domain tracking — attribution is limited to HubSpot-captured touchpoints

Frequently Asked Questions
What attribution models are included?+
The Assembler computes three models: first-touch (100% credit to first interaction), last-touch (100% credit to last interaction before deal creation), and linear (equal credit across all touchpoints). The report presents all three so your team can compare and decide which model fits your go-to-market.
What is dark funnel detection?+
Dark funnel refers to deals that close without any attributable marketing touchpoints in HubSpot — the prospect path is invisible to your tracking. The Assembler counts these deals and estimates the revenue impact, helping quantify how much pipeline is outside your measurement system.
Does it integrate with ad platforms?+
Not directly. The Fetcher reads HubSpot contact timeline events, which include UTM parameters and campaign memberships. If your ad platforms push UTM-tagged traffic that HubSpot captures, those touchpoints are included in attribution. Direct ad platform API integration is not included.
Is there a refund policy?+
