Upstack Signal — Server-side tracking for DTC
Upstack Signal’s 750M+ device graph restores the cookies, click IDs and hashed customer identifiers that server-side tracking alone still misses.

US device IDs, growing every month.
Browser, device, and click signals resolve against a national identity network.
Matches persist across device changes and browser churn, so signal compounds over time.
The graph gets stronger as more events, devices, and commerce signals flow through it.

Upstack screens traffic before delivery, so platforms learn from real customer actions, not bots, fraud patterns, junk referrers, or duplicates.




Marketing optimization
Turn incomplete conversion data into complete customer profiles to power sharper prospecting, higher match rates, and recovered revenue — on every channel you spend on.
More matched buyers means more room to bid. Budget rises hard while CPA barely moves — same creative, same targeting discipline.
+85% ad spend, CPA +4%Meta learns from complete customers instead of fragments, so acquisition budget stops chasing people who were never in market.
Lower CACRe-identified emails attach before events reach Klaviyo, so browse and cart flows fire for people the pixel lost.
More flow revenueMore hashed parameters on every Google event — email, phone, address, external ID — so more conversions come back matched.
Higher match rateNew-versus-returning resolves before the platform sees the event, so budget stops re-buying customers you already have.
