Identity fragmentation is eating your margins. Five cookies ≠ one customer. You can’t personalise or suppress if you don’t know who you’re targeting.
"If you don’t own your customers’ IDs, you’re renting your future.” In 2025, that’s not just a punchline—it’s your P&L reality.
Let’s break it down.
Ad spend inflation (YoY): +12%
First-party signal loss: −40%
Reacquisition waste: 15–25% of budget
When you can’t recognise your own customer across browsers or devices, you’re paying platforms to win them back. You didn’t lose them—they just logged out, switched tabs, or blocked a third-party tracker.
And here’s the kicker: 5 cookies ≠ 1 customer.
Today’s martech stacks are identity silos in disguise. One customer might show up as:
A session in GA4,
A newsletter click,
A “lookalike” in Meta,
An anonymous visit in your personalisation engine.
Without a persistent ID that spans all touchpoints, your campaigns are blind. And every blind spot is a margin leak.
Symptoms of identity fragmentation:
Low match rates in paid media
Limited suppression capabilities
Weak personalisation (esp. on Safari, Firefox)
Over-reliance on logins or probabilistic stitching
Incomplete attribution and wasted spend
Sound familiar? You’re not alone.
Teavaro’s Identity Activation Hub gives you what the platforms won’t: a deterministic, real-time identity graph that’s yours.
What does this look like in action?
Real-time resolution (<300ms) across all touchpoints.
Server-side privacy layer with consent enforcement.
Unified Marketing ID (UMID): a persistent key across web, app, and CRM.
First-party control: You own it. You activate it. You monetise it.
This means:
60%+ user identification even without login (vs. industry avg. 10–15%).
Reacquisition costs slashed by up to 30%.
Match rate improvement of 2x–3x in paid media.
Lift in personalisation CTRs and conversions.
The result? Better ROI, smarter AI, and freedom from walled garden rent.
A leading European telco used Teavaro to tackle identity fragmentation head-on. Before:
Paid media was re-engaging existing customers unknowingly.
Match rates hovered below 30%.
Consented users weren’t recognised across sessions or devices.
After:
Teavaro deployed UMID in under 30 days.
Identity resolution reached 65% on first-party traffic.
Suppression and lookalike targeting improved dramatically.
Net result: Reacquisition spend cut by €4M/year. Attribution clarity restored. Customer trust reinforced.
That’s owned growth in action.
Do you use deterministic or probabilistic identity?
Is your identity graph owned and hosted by us—or you?
Can you resolve identities across all devices and domains in real time (<300ms)?
What suppression and match rate uplift can we expect in paid media?
How fast can we deploy—without replatforming?
If your current vendor dodges these, you’re not buying growth. You’re renting it.
Walled gardens were never designed to build your business—they were built to tax it.
Teavaro flips the script with a white-box, privacy-proof identity layer you control. It’s fast, open, and built for enterprise scale—without the vendor lock-in or “CDP” baggage.
Identity ownership means your company—not a third-party platform—controls the identifiers and logic that connect users across sessions, devices, and channels.
Deterministic identity uses exact signals (e.g., login, transaction ID) to resolve individuals. Probabilistic methods rely on guesswork. Teavaro is deterministic, real-time, and privacy-proof.
Neither. Teavaro is an identity activation hub. It connects and powers your existing stack—without the need to replatform.
Yes. With UMID, you can deliver real-time, consented personalisation across browsers and domains even when the user is anonymous.
30 days to production. Teavaro integrates server-side and uses open APIs, no long replatforming required.
