We focus on subscription businesses, so we'll usually scope your setup live on the same call. Talk to sales → Does 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. ## Stop scaling on trial signups. Start scaling on ARR See which ads drive real ARR, not just trial signups. Tie every paid customer, expansion, and churn back to the source, so you can scale the channels producing actual revenue.
