Scale on paid users,
not trial signups.
See which ads bring in trials that actually convert to paying customers. Cometly connects Stripe to every ad platform so you can scale what drives real ARR, not what makes your trial counter look good.

Cohort LTV
See real ROAS, on your real timeline.
The ads you ran in March turn into MRR all the way through April, May, and June. Cometly groups every paying customer back to the trial they started, so you see real year-1 LTV ROAS, not the noisy month-1 number.
- Track revenue from when the trial started, not when they paid
- Compare 30, 60, 90-day, and full-year ROAS side by side
- Slice any cohort by source, campaign, or single ad
- Filter out organic so paid never gets over-credited

What you actually get
Built for self-serve SaaS.
Priced for growth teams.
Credits the channels that actually drove the sale
First-touch, last-touch, linear, and source-specific, all side by side. Source-specific is built for SaaS: if Meta touched the journey, Meta gets the credit it earned.
Pushes paying-customer data to every ad platform
Send paid conversions (not just trial signups) back to Meta, Google, LinkedIn, TikTok, Microsoft, and Reddit. Cometly enriches every event with fingerprint and hashed PII so Meta rates the data as “Great”.
Tells Meta to find more buyers, not more browsers
Switch your Meta and Google campaigns from “trial start” to “new paid customer.” The algorithm goes after people who actually open their wallets.
Follows every user, even across devices
The Comet Pixel works without cookies. A click on a phone becomes a trial on a laptop becomes a paid upgrade in email, all credited correctly.
Tracks customers for years, not days
Build cohorts by trial month, plan, source, or campaign. Track LTV out 12, 24, even 36 months, long after most tools have forgotten the click.
FAQ
What PLG teams ask before signing up.
Don't see your question? Book a call. We focus on subscription businesses, so we'll usually scope your setup live on the same call.
Talk to salesDoes Cometly replace Mixpanel or PostHog?
No. They answer different questions. Mixpanel or PostHog tells you what users do inside your product. Cometly tells you which ad they came from and what they paid. Your CRM runs pipeline and customer relationships. Most PLG teams run all three side by side.
How does Cometly know a trial converted to paid?
We listen to Stripe directly. Trial started, first recurring payment, renewals, refunds, and churn all flow in automatically. No webhooks to wire up. The data shows up in your dashboard and gets sent back to ad platforms the same day.
Our trials take 14 or 30 days to convert. Will this still work?
This is exactly what Cometly is built for. Cohort dashboards group trials by start date and follow them as long as you need: 30 days, 90 days, even out to year-3 LTV. Most ad platforms forget the click after 7 days. We don't.
We use a $1 trial. Does that still work?
Yes. Cometly separates $1 trial starts, full subscription starts, and recurring payments. You can optimize Meta on “new paid customer” instead of “trial start”, so the algorithm chases buyers, not bargain hunters.
How long does setup take?
A few hours. Drop in the Comet Pixel (one script tag), connect Stripe, connect your ad accounts, pick your events. Most PLG SaaS teams are live the same day they sign up.
What is match quality and why should I care?
Meta scores the data you send through its Conversion API on five tiers: Poor, Okay, Good, Very Good, and Great. The higher the tier, the better Meta's optimization can find lookalike buyers. Cometly enriches every event with IP, user agent, fingerprint, and hashed email and phone so events land in the top tier. Pixel-only setups usually sit much lower.
