What was measured
Period and population
A used-car marketplace in Malaysia, Indonesia and Thailand, with a separate site for dealers: three country sites and the dealer site, all together. The months are January to September 2026, with September counted from 1 to 29. Every count was read from Releva's own event store on 29 September 2026. Test and staging sites are left out.
What counts as a result
This page shows how much the agent carries, not what it sold. The measures are events recorded, searches recorded, profiles live, journey entries, and email and push delivered. There is no revenue figure on the case study, on purpose.
How an order is credited
No order is credited here. Nothing on the case study is attributed to a channel; the figures are counts of what the marketplace sent and what the agent did with it.
Controlled or observed
Observed volumes. The one-day peak of 9 April 2026, 25.7 million events and 22.6 million journey entries, was a run on the whole base. After it, journey entries settled at 3 to 9 million a month.
What the numbers do not say
They say nothing about conversion or revenue. The searches count only from March 2026, when the marketplace started sending them. Merged and deleted profiles are not in the 22 million.
The terms on the case study
| Term | How it is defined here |
|---|---|
| Event | One recorded interaction: a page view, a search, a session, one of the marketplace's own events such as a car viewed or a loan calculator used, a journey entry, or a message sent or delivered. |
| Own event type | An event the marketplace defined itself and sends to the agent. 570 different ones in August 2026. |
| Profile | One live record per shopper, anonymous visitors included. 22 million on 29 September 2026; 2.9 million with an email or phone number; 1.5 million registered accounts. |
| Journey entry | One shopper entering one journey. 22.6 million in one day on 9 April 2026. |
| Delivered | An email or push message the email or push service confirmed as delivered: 8.7 million in March 2026, 6.5 million in the first 29 days of September. |
| Searches recorded | Search queries the marketplace sent to the agent, from March 2026: 21.7 million in August. |
What was switched on, in order
Every interaction sent
Page views, searches, sessions and the marketplace's own events, from a car details page viewed to a loan calculator used, in one event store.
One profile per shopper
Every event joins one profile, across the three country sites and the dealer site, anonymous visitors included.
Searches added
From March 2026 the marketplace sends its searches too: 6.2 million that month, 21.7 million in August.
Journeys on the whole base
Journeys run on the full profile base; the 9 April 2026 run entered 22.6 million shoppers in a day.
Push and email
Messages go out from the same profiles: 3.3 million delivered in January, 8.7 million in March, 6.5 million in the first 29 days of September.
To check it in your own store
Count the events your platform and app produce in a month, including your own event types, and the profiles you can tell apart, anonymous ones included. Those two numbers say what size of agent you need.
Then count the messages delivered in a month and the searches run. Volumes like these are a load test, not a result; the result comes from the holdout the agent runs once it is live.

Thirty minutes, with your store and ad accounts open. Then 30 days free. A holdout group decides: if the agent doesn't add orders in 30 days, you don't pay.
