Meridian is the only platform built to measure the decision-stage reasoning inside LLMs — where over 80% of brand conversations end, and where the sale is actually decided.
Across 1,000+ live buying-journey probes spanning 14 industries, only 14% of brands survive to win the final AI recommendation. The majority are eliminated at turn three — the moment the AI moves from "here are options" to "here's what I'd choose."
Visibility tools measure whether a brand appears at turn one. That's not where the sale is decided. This is what nobody else is measuring.
Since April 2025 we've mapped how ChatGPT, Gemini, Perplexity and Grok actually reason about brands — across anti-ageing skincare, financial services, CPG, SaaS, pharmaceuticals, luxury, travel, automotive and beyond.
The patterns are consistent, measurable, and specific to each platform: Gemini's educational drift arc, Perplexity's live retrieval displacement, ChatGPT's training-data anchoring, Grok's recency bias. Meridian operationalises a year of research into a live measurement platform.
Profound, Peec, Scrunch and Evertune measure turn one only. Meridian follows the conversation through to the purchase moment — up to ten turns — capturing where your client is displaced, by whom, and why.
Twelve months of observation has catalogued the distinct reasoning patterns that govern each platform — educational drift, clinical-evidence anchoring, live retrieval cascades, authority substitution. We know which patterns displace brands where.
Not "are you cited" — "you held position through T3 on Perplexity, then Augustinus Bader displaced you at T4 via clinical science citation dominance." Actionable, named, sequenced remediation.
Agentic shopping. LLM-native ads. Autonomous buying agents. Meridian is measuring agent-readiness now — so when your client's category goes agentic, your agency already has a plan.
Turn-by-turn journey mapping with DIT detection, handoff analysis, and named displacement capture across directed and agentic modes.
Platform Stability of Organic Scoring — breadth, depth, resilience, sentiment, decay. Fragile / Moderate / Strong banding across every major AI platform.
Which sources the LLM is actually trusting — Tier 1 training data, Tier 2 authority, Tier 3 immediacy — and where your client's citations rank.
A single platform-level verdict per brand — amplify, monitor, or remediate — with a sequenced programme of interventions from T1 to T3.
Meridian is multi-tenant from the ground up. One workspace, every client. Your logo on every deliverable. Remediation plans the account team can actually execute.
Every client in one dashboard. Isolated data, shared methodology.
Your logo on every PDF, every report, every deliverable sent to the client.
Sequenced T1, T2, T3 programmes with dependencies — the work the team does next.
Weekly, monthly, quarterly — measure the intervention's effect on the journey.
Agentic shopping arrives through 2026. LLM-native advertising is launching on ChatGPT this year. Gemini Shopping is already in market. When an AI agent buys on behalf of your client's customer, the decision is made by the model — not the person — and the rules of that decision are exactly what Meridian has spent twelve months decoding.
Brands that measure now will be positioned when the shift happens. Brands that wait will find out, too late, that they were invisible at the moment that mattered.
Meridian is the latest commercial offering from the team behind the AIVO Standard — the research programme establishing the measurement standards for AI-era brand discovery.
Twelve months of primary research across financial services, pharmaceuticals, consumer goods and beauty have produced the methodologies now operationalised inside Meridian — PSOS, Buying Journey Probe, Citation Chain, Ad Readiness, and the forthcoming Agentic Readiness framework. This work is published continuously in the AIVO Journal and referenced in Fortune, AdAge, Business Insider and American Banker.
