Ask any general LLM about your 2.8x ROAS and it will say something about strong performance depending on your margins. Ask Meridian and it tells you you're at the 47th percentile for your sector, what the top 10% are doing differently, and which lever to pull first.
Meridian isn't bolt-on AI. It's a ground-up model stack built on a foundation LLM, fine-tuned on 24 million labelled marketing outcomes, and augmented with a live benchmark database that updates every 24 hours.
Built on Llama 3.1 70B, one of the strongest open-source foundation models available. Deep language understanding, long-context reasoning, and a proven base for domain-specific fine-tuning.
Fine-tuned on 24 million labelled agency report outputs, channel-specific analyses, and expert commentary, all labelled by actual campaign outcomes. This is what makes Meridian different from every other model.
At inference time, every query is enriched with live benchmark data: your sector, your channel, your budget tier. Meridian doesn't guess what good looks like. It looks it up.
Every agency that joins Meridian makes it smarter for everyone else. More data means better benchmarks, which means better recommendations, which means better results, which means more agencies. That compounding advantage is the moat no competitor can buy.
Meridian's benchmark database covers 15 channels, 12 sectors, and 6 budget tiers. Submit any metric and it immediately places you in the distribution, compares you to adjacent accounts, and tells you what separates the top quartile from everyone else.
Every metric you submit gets benchmarked against real accounts in your sector, your channel, and your budget range. 47th percentile. Not just good or bad.
Meridian forecasts aren't statistical projections. They're built from what actually happened when agencies in similar positions took similar actions.
Budget move recommendations come with real confidence intervals drawn from 24 million labelled data points across your exact spend tier.
Meridian knows which creative formats burn out fastest in your sector, which angles drive the highest CTR, and when to rotate before you lose ROAS.
Something dropped 30% overnight. Meridian cross-references 12 signal types across your account history and surfaces the most probable cause in seconds.
15 channels. One story. Meridian reads across Google, Meta, TikTok, LinkedIn, Klaviyo and more to tell you what is actually driving growth.
Brief Meridian on a client objective and it outputs a prioritised 90-day strategy grounded in what has worked for comparable accounts in that sector.
Meridian identifies audience fatigue, overlap, and expansion opportunities by drawing on behavioural signal patterns from 800,000+ ad accounts.
Go beyond last-click. Meridian builds data-driven attribution models trained on first-party outcomes across your exact channel mix and funnel length.
GPT-4o, Claude 3.5, Gemini 1.5 Pro, and Mistral Large are all excellent general-purpose models. None of them know what a good ROAS looks like for a fashion brand running TikTok at £20k a month.
