How Cometly helps
Close the gap between ad platforms
and revenue you can defend.
Cometly stitches anonymous browsing to Stripe payouts, improves server-side conversion signals for every major ad network, and keeps one reconciled view so leadership debates strategy instead of whose export is right.
One revenue-backed story for the board
Attribute trials and paid customers through to Stripe so Meta, Google, and LinkedIn performance is judged against cash collected, not platform-reported conversions alone.
Credit the touches before anyone fills a form
The Comet Pixel fingerprints visitors anonymously and stitches sessions across devices and blockers, so weeks of activity before identify still earn attribution.
Cleaner data feeding the ad algorithms
Server-side Conversion API sends hashed identity and CRM-backed events to Meta, Google, LinkedIn, and TikTok so match quality improves and optimization learns from buyers, not noise.
Replace spreadsheet Mondays with a live source of truth
MRR by source, trial-to-paid by campaign, and cross-platform totals stay in one workspace, with optional AI digests to Slack so reconciliation is a quick review, not a half-day project.
What you actually get
Everything attribution software
should have been all along.
Server-side events
Server-side tracking captures every conversion your browser-side pixel misses: OAuth flows, ad blockers, iOS privacy. No more 30% conversion gaps.
Native Stripe revenue
Trial signups, paid conversions, MRR, expansion, refunds, and churn flow into Cometly directly from Stripe, so every report ties back to GAAP revenue.
Eight attribution models
First-touch, last-touch, last non-direct, source-specific, linear, linear paid, and U-shaped. Compare side by side to spot under-credited channels.
Multi-touch on every system
Touchpoints from the Comet Pixel, server-side events, ad platforms, CRM lifecycle changes, and Stripe revenue, all stitched into one journey.
Conversion API
Send paying-customer events back to Meta, Google, LinkedIn, TikTok via server-side CAPI. Match quality typically hits 9.3 / 10, far above manual setups.
Pipeline attribution
Map ad spend to HubSpot or Salesforce lifecycle stages (MQL, SQL, demo booked, opp, closed-won) at the campaign and individual ad level.
Account journeys
B2B buying committees treated as a single account, not separate leads. Every touch across every contact credited back to the originating ad.
AI ads command center
Pause, scale, or rebalance every campaign across every ad platform in one place. AI surfaces high-performing ads grounded in your real revenue data.
AI Chat for ads data
Ask anything in plain English. "Which Meta campaigns dropped trial conversion last week?" Answers cite the underlying campaigns and run in seconds.
Audiences from Stripe LTV
Build look-alikes off your highest-LTV customers and sync to Meta, Google, LinkedIn, and TikTok. The algorithms learn from buyers, not browsers.
Reports straight to Slack
AI-generated daily, weekly, and monthly digests. Pipeline by source, top movers, spend anomalies, delivered to Slack with AI commentary on what changed.

Talk to salesWhat is marketing attribution software?
Marketing attribution software tracks every touchpoint in the customer journey (ad clicks, page visits, form fills, demos, trials, and purchases), then assigns credit to each touch when a customer converts. The goal is to know which marketing investments actually drove revenue, so you can spend more on what works and stop spending on what doesn't.
How is Cometly different from GA4 and Meta's reporting?
GA4 and Meta both lose 30–50% of conversions to ad blockers, iOS privacy, and cross-device drop-off, and each platform has an incentive to over-report its own performance. Cometly is cookieless, server-side, and reconciles back to Stripe so the numbers actually match revenue.
Do we need engineers to set Cometly up?
No. The Comet Pixel is one script tag. OAuth handles Stripe, your CRM, and every ad platform. Most teams are tracking real data inside hours. Engineers only get involved for custom Salesforce triggers (about half a day of work).
Which attribution models does Cometly support?
Eight: first-touch, last-touch, last non-direct, first-touch source-specific, last-touch source-specific, linear, linear paid, and U-shaped. Switch models retroactively in the Report Builder. Most teams pick one primary model and 1–2 sanity-check models.
What attribution windows does Cometly support?
1 day, 7 day, 14 day, 30 day, 60 day, 90 day, and Lifetime (LTV). Short e-commerce cycles usually run on 1–7 day windows. B2B SaaS typically picks 30–90 day or lifetime so multi-month deals stay attributed.
Does Cometly work with HubSpot and Salesforce?
Yes, both, with two-way sync. We pull lifecycle stages, deals, and revenue, and push enriched attribution data back. No rip-and-replace of your CRM.
How does Conversion API improve ad performance?
Server-side CAPI sends conversions to Meta, Google, and LinkedIn with hashed email, phone, IP, user agent, click IDs, and CRM properties. Match quality jumps from a typical 4–5 / 10 to 9.3 / 10. Higher match quality = better optimization, better look-alikes, lower CAC.
What does Cometly cost?
Cometly offers two plans: Core (everything a B2B SaaS revenue team needs to attribute pipeline and revenue) and Enterprise (advanced security, scale, warehouse export, MCP, and dedicated support). Pricing is usage-based and tailored to your existing website sessions and ad spend. We size your tier in the demo and quote pricing live — see /pricing for the current breakdown.
What if it doesn't work for our team?
Core ships with a 60-day commitment-free opt-out. Full money-back if it isn't a fit. We'd rather you leave than carry a customer who isn't getting value.
