What Is Cometly

Cometly is a marketing attribution platform built for B2B SaaS. It unifies ad spend, web sessions, CRM pipeline, and Stripe revenue into one revenue-grade attribution model, so marketing teams can see which campaigns drive paying customers, send enriched conversion data back to ad platforms via Conversion APIs, and replace fragmented spreadsheet reporting with live dashboards.

At its core, Cometly captures every visitor through a first-party, server-side pixel that survives ad blockers, iOS ITP, and OAuth flows. Touchpoints are stitched to leads when they hit the CRM (HubSpot, Salesforce) and to paying customers when they convert in Stripe, producing a single, accurate picture of the funnel from first click to closed-won revenue.

Unlike attribution tools built primarily for e-commerce or info-products, Cometly is built around the realities of B2B SaaS: long, multi-stakeholder buying cycles; pipeline stages that matter as much as final revenue; CRM-first reporting; and trial-to-paid, MRR, and ARR as the metrics leadership actually runs on.

Marketing Attribution Platform

Cometly is a complete marketing attribution platform, not just a pixel or a dashboard. It spans data capture, identity stitching, attribution modeling, and outbound conversion sync to ad platforms, all in one workspace.

Server-Side Pixel & Tracking

The Cometly Pixel is a one-line, first-party install that captures every visitor automatically. Because events are processed server-side, tracking is resilient to ad blockers, iOS ITP, Safari, and OAuth-mediated redirects that break traditional client-side pixels. Cross-domain stitching is built-in, so journeys that span a marketing site, a docs site, and an app subdomain remain a single session.

Multi-Touch Attribution

Cometly ships eight attribution models (first-touch, last-touch, linear, U-shaped, time-decay, position-based, custom, and full-path) with configurable attribution windows from 1 day to lifetime LTV. Reports can be sliced per channel, per campaign, per ad, per landing page, per CRM stage, or per cohort, and saved as custom dashboards for the metrics leadership actually reviews.

Conversion API

Cometly’s Conversion API sends enriched, server-side conversion events to Meta, Google Ads, LinkedIn, and TikTok with a typical match quality of 9.3/10. Because the events are sent server-side with first-party identifiers and revenue values, the ad platforms can optimize bidding for paying customers (not form fills), which materially improves ROAS and CAC payback for B2B SaaS advertisers.

Customer Journeys

Cometly maps the full customer journey at the account and contact level: every touchpoint (paid click, organic visit, demo booked, deal stage moved) and the people involved at each step. Journeys are the surface most B2B teams use to investigate why a deal closed, or why a high-spend campaign isn’t producing pipeline.

Revenue Attribution

Native integrations with Stripe (and HubSpot, Salesforce, Chargebee on the CRM/billing side) let Cometly tie every ad to MRR, ARR, and trial-to-paid conversion, not just clicks or signups. This is the layer that lets revenue-grade attribution work for SaaS pricing models, expansion revenue, and multi-stakeholder deals.

AI & Automation

AI in Cometly is grounded in the attribution data already in your workspace, not a generic LLM wrapper. Four surfaces:

Ask AI

A natural-language Q&A interface for live attribution data. Ask questions like “which campaigns produced the highest LTV customers last quarter?” or “what changed in our paid CAC last week?” and get answers in plain English. No SQL, no analyst queue, no waiting on dashboards.

AI Ads Manager

A unified console across every ad platform with attribution context inline. AI suggestions tell teams what to pause, scale, or rebalance based on real revenue performance, not surface-level ROAS or in-platform CPA.

AI Slack Reports

Cometly pushes daily and weekly performance summaries directly into the Slack channel your team already lives in. Reports are scoped per channel (paid, organic, lifecycle) and per audience (growth, ops, leadership) and can be configured to alert on anomalies.

MCP Server

Cometly publishes an MCP (Model Context Protocol) server that lets AI tools like ChatGPT, Claude Desktop, and Cursor connect securely to a workspace and pull attribution, dashboards, and journey data into their answers. The MCP server is part of the Enterprise plan for teams standardizing on AI tooling.

AI Policy

All AI features follow the Cometly AI Policy, which covers data handling, model selection (xAI, Anthropic, OpenAI), retention, deletion, and compliance with GDPR, CCPA, and the EU AI Act.

Frequently Asked Questions

Limitations

• Cometly is purpose-built for B2B SaaS and revenue-grade attribution workflows. Pure e-commerce / D2C teams with no CRM may get more out of Shopify-native attribution tooling.
• Cometly is a web-based SaaS application. There is no dedicated native mobile app today; the web app is fully responsive on mobile browsers.
• Cometly ingests ad-platform data via official APIs. Platforms that don’t expose ad APIs publicly are not supported until those APIs become available.
• AI features (Ask AI, AI Ads Manager, AI Slack Reports) rely on third-party LLM providers (xAI, Anthropic, OpenAI) as documented in the AI Policy. Their model availability and rate limits apply.
• New workspaces with no historical pipeline or revenue data will see attribution begin from the day the pixel is installed and systems are connected. Cometly does not backfill data that never existed in the source platforms.
