The plans
Cometly does not publish public prices. Pricing is quote-based, sized to your usage and quoted on a sales call.
Cometly quotes every plan on a sales call. Core and Enterprise are both priced on monthly pageviews, which the vendor estimates at about 1.5 times sessions. No figures are published. Billing is monthly or annual, and annual saves 20%. There is no free trial, and a paid Professional Onboarding takes its place. One buyer publicly reported a $600 a month quote.

Is it worth the money?
Cometly is a working B2B SaaS marketing attribution platform with named customers and a 4.8 G2 record, built to tie paid ad spend to Stripe revenue and CRM pipeline, from first click to closed-won. You are unlikely to regret it if that is your job and the live demo proves the tracking on your own data first. It publishes no price and offers no free trial, so that demo is the proof you get before you commit.
What works
- Ad spend is matched to revenue that reached Stripe. The Comet Pixel and server-side events feed Stripe revenue and CRM deal stages into the attribution, so you see which campaign produced pipeline and closed-won revenue, with MRR and LTV attached.
- Server-side Conversion API to seven ad platforms, on both plans. It sends deal-stage-aware events to Meta, Google, LinkedIn, TikTok, Microsoft, Reddit and Snapchat, so the bidding optimizes toward paying customers. The vendor claims Meta event match quality up to 9.3 out of 10.
- Multi-touch models built for long B2B journeys. First, last, linear, U-shaped and data-driven attribution, with the full pre- and post-form touch history written onto each deal in HubSpot or Salesforce, which is the part a CRM's own tracking usually cannot see across a weeks-long sale.
- A strong, consistent G2 record. 4.8 out of 5 from 36 reviews, 34 of them five-star, with praise clustering on attribution accuracy, custom-event tracking and fast, human support. One reviewer reported accurate tracking on over $100,000 a month in ad spend.
- 70-plus native integrations and done-for-you onboarding. Stripe, HubSpot, Salesforce, Close, HighLevel and the major ad platforms connect in minutes, and a specialist wires your stack up, which matters because attribution is only ever as good as its setup.
What to watch
- No public pricing. The two plans, Core and Enterprise, carry no numbers. Pricing is usage-based on your monthly pageviews and quoted on a sales call, so you cannot line its cost up against a competitor before you talk to sales. Some buyers report the quote feels high, one G2 review titled bluntly "Not worth of it's price."
- Cometly offers no free trial, arguing that attribution needs your CRM and ad platforms wired up first, and sells a paid onboarding instead. You commit, or at least pay to get set up, before you see it run on your own traffic, which makes the live demo the one look at your real numbers you get up front.
- Thin proof outside G2. Trustpilot sits at 3.6 from 92 reviews and flags that only a handful are recent and the sample may not be representative, and there is no clear Capterra listing. The G2 record is good but small, so the trial you cannot take is exactly the due diligence you would most want.
- Its models will not perfectly match Meta, Google, GA4 and your bank at once, and its accuracy depends on your UTMs and CRM hygiene. Use its numbers to choose where the next dollar goes, and reconcile them against a second source.
- Some rough edges reviewers name. A couple report documentation that lags the actual app, one flags pricing changing after they signed, and a Trustpilot reviewer found it "just another tool with a bunch of complicated options." None is disqualifying, but budget setup time and expect to lean on support early.
