How Helio found the channel that actually pays.
Their old analytics was heavy, sampled on busy days, and needed a cookie banner that hurt conversion.
They swapped in Mrkr in an afternoon, kept it cookieless, and started sending revenue with their signup events.
They cut analytics weight, dropped the banner, and found that one underrated channel drove most of their paid plans.
The old way, and the lighter way.
- A cookie banner on every page
- 45 kB of script
- Sampled data on busy days
- Your data living on their servers
- No banner, cookieless by default
- About 2 kB, async
- Every event, never sampled
- Data you can export anytime
