Comparison
The agile challenger versus the institutional standard. Insight teams comparing these two are really choosing between research velocity and evidentiary weight — here's how that trade actually plays out.
Zappi turned panel research into a self-serve platform: templated, validated studies your own team launches, results in hours-to-days, and a connected data asset that compounds across studies. The pitch is throughput — more research, run closer to the teams that need it, without an agency in the loop. For organizations trying to democratize insight work, that's the draw.
Link is the reference instrument: branding, persuasion, enjoyment, short-term sales likelihood, and long-term equity effects, measured against one of the largest ad-test norm databases ever assembled. When a global campaign decision must survive a boardroom or a legal-of-marketing review, Link-grade evidence is the currency. LinkAI extends the franchise with model-accelerated scoring trained on that same database.
Cost per study and speed: Zappi. Normative authority: Link, and it isn't close — decades of validated campaigns back every score. Self-serve control: Zappi; Link still runs closer to a managed research engagement. Global market coverage: Link's fieldwork infrastructure is hard to match. Pricing transparency: neither — both are quoted, not listed (see Zappi pricing and Kantar Link pricing).
Even Zappi's agile economics can't cover every cut of every feed ad — and Link never tried to. That's the screening gap: PreTestAds scores attention in minutes for a credit, benchmarked against 76 top-performing TikTok ads, with Hook Strength and the exact drop-off second. From $49/month, up to 8 free credits. Run it on everything; send survivors to the panel. Full comparisons: vs Zappi · vs Kantar Link.
High research volume across a broad innovation pipeline → Zappi. Fewer, heavier decisions with global stakes → Link. Either way, the stack is incomplete without a cheap gate in front: creative volume is growing faster than any panel budget, and untested creative is where the money leaks.

LinkAI is Kantar's AI-accelerated variant, trained on Kantar's ad-test database — faster and cheaper per asset than full-fieldwork Link, sold through the same enterprise channel. It's Kantar's own acknowledgment that per-study fieldwork can't cover modern creative volume.
Model-based attention screening. PreTestAds scores an ad against 76 top TikTok performers in minutes for about $2 — the layer teams run before panel research so fieldwork budget only goes to creative that already holds attention.
