Their complaint: a bill that jumps with every new user
No per-user pricing.
A tenth of what you pay today, however many people visit. Growth shouldn't be a billing event.
Instead of Segment and mParticle
The same API as Segment, so you change one line. The tools people actually use, done properly. And when something goes wrong, you can see exactly what happened.

We read what customers say about it, and started from their complaints.
Their complaint: a bill that jumps with every new user

Their complaint: small mistakes take ages to find
Click any event. See exactly what we sent to each tool, and exactly what each tool said back, in words you can act on.
Their complaint: hundreds of thin connectors
Amplitude, Mixpanel, Google Analytics, Meta, HubSpot, Braze, Customer.io, Intercom, Slack, S3, EngageMage, and a signed webhook for the rest.
Their complaint: tracking plans cost extra
Everything arriving shows up with its fields and types. One click says it's expected. A changed type or a stray email address gets flagged.
Their complaint: anonymous and known people don't join up
Each person's IDs, and every event across their devices, on one page. A bad join is obvious.
Their complaint: retries stop after four hours
A tool being down holds its own place for a day and catches up by itself. Replays are free, and any tool can replay two weeks.

The demo has a little coffee shop's data flowing through it, with one tool misbehaving. See how quickly you can tell why.
