What is Cometly?
Cometly is a marketing attribution platform that tracks which ads and channels lead to pipeline, customers and revenue, then sends that conversion data back to ad platforms. It is aimed mainly at B2B and AI SaaS companies, agencies and growth teams that spend heavily on Meta, Google and LinkedIn ads and want a clearer picture than each platform's own reporting provides.
Cometly uses its own pixel with server-side, cross-device tracking to reduce data lost to ad blockers and browser privacy limits. On top of the tracking layer, it offers multi-touch attribution models, revenue dashboards, a plain-language data agent and an AI ads manager. It connects with CRMs such as HubSpot, Salesforce and Attio and billing tools such as Stripe and Chargebee.

Cometly FAQ
Is Cometly free?
No. Cometly does not offer a free plan, and its pricing page states that there is no free trial. It sells a Core plan and an Enterprise plan, both available on monthly or annual billing with a 20% saving for annual payment. Exact prices are not listed on the page, so you need to contact the team or book a demo.
What is Cometly used for?
Cometly is used to track which ads and marketing channels generate pipeline and revenue. Marketers install its pixel, connect ad accounts and a CRM, and then see CAC, ROAS and LTV by campaign. It also sends conversion data back to Meta, Google and LinkedIn so those platforms can optimize toward customers who actually pay. Its AI agent also answers plain-language questions about the data.
What happens if I exceed my Cometly usage limit?
According to Cometly's pricing FAQ, the platform does not throttle attribution if you go over your pageview limit. Instead, your account moves to the next usage tier at the start of the next billing period. This means tracking continues without gaps, but your bill can rise as traffic grows.
