Cometly
Ad attribution with server-side conversion sync for paid media teams
Cometly is a ad management & attribution tool for E-commerce and Agencies, offered as paid. Founded in United States in 2021.
About Cometly
Cometly is a marketing attribution platform that ties ad clicks to leads, pipeline and revenue, then sends those conversions back to ad platforms. It is run by Comet LLC, a small company founded in 2021 in Newtown, Pennsylvania. Its core job is showing media buyers which campaigns and creatives actually produce revenue.
The product combines a first-party pixel, server-side tracking, multi-touch attribution models, customer journey views and dashboards that join ad spend with CRM and Stripe or Shopify revenue. Its Conversion API sync pushes enriched events back to Meta, Google, TikTok, LinkedIn and others so their algorithms optimize on real outcomes. Pricing is quote-based in two plans: Core for attribution and ad management, and Enterprise, which adds CRM and warehouse sync with Snowflake and BigQuery, an API and MCP access. Plans are tiered by monthly pageviews, and annual billing saves 20 percent.
Cometly suits performance marketers, agencies and info or SaaS businesses spending heavily on Meta and Google who need cleaner data for scaling decisions. There is no free trial and no public price, so small advertisers cannot test cheaply. Hyros targets a similar high-ticket audience with call tracking, Triple Whale is the stronger choice for Shopify brands, and Northbeam leans toward larger DTC brands with media mix modeling.
Instead of a free trial, Cometly sells a paid Professional Onboarding package with a dedicated specialist, arguing attribution needs CRM and ad setup first. Ask for a test against your current reporting before signing an annual plan.
