Upstack Signal — Server-side tracking for DTC
Train ad platforms to find more customers
Upstack Signal’s Consumer Identity Network restores the cookies, click IDs and hashed customer identifiers that server-side tracking alone still misses.
Network scale
Upstack’s server-side consumer identity network.

Durable profile
Matches persist through device changes and browser churn, so signal compounds.
Monthly lift
The graph strengthens as more events, devices, and commerce signals flow through it.
Identity resolution
One customer profile behind every event.
Signal turns fragmented browser, device, and click data into a durable person-level profile before the event reaches your ad platforms.
Event match quality
Higher match rates drive top of funnel performance.
Upstack improves server-side tracking quality by enriching every event with the identifiers platforms need to recognize more customers.

In their words
What operators say about event match quality.
Favorite software tool rn - upstackdata.com. Very quickly improved Lark Meta event matching. Easy setup for non-technical people like me, @michael_upstack helped clean up all of the poor setup I had previously done with other tools, and pricing is solid.
We did see an uplift when we onboarded with @upstackdata, yes. Our EMQ scores improved by circa 20%.
I also wanted to share that @upstackdata has greatly helped my client. Previously, they only saw 50% of their sales on Meta, but now it's around 80%. I believe it significantly improved their results.
One of the biggest unlocks this year has been trusting @michael_upstack and using @upstackdata. There are Elevar, Black Crow, Little data, Triple whale and a bunch of others CAPI providers but so far we've added it to close to 20 accounts.

Signal hygiene
Keep bad signal out of your pixels.
Upstack screens traffic before delivery, so platforms learn from real customer actions, not bots, fraud patterns, junk referrers, or duplicates.
