Every signal you have. One calibrated truth.
Platform reports, MMM outputs, incrementality tests, geo experiments, media audits, strategy docs — you already have the data. What you don't have is agreement. Eichen takes a 360-degree view of everything your measurement stack produces, harmonizes conflicting signals, and delivers one decision-ready output. Not a replacement for your tools. The calibration layer on top that makes them useful.
You don't have a data problem. You have an agreement problem.
Your team already has platform data, MMM outputs, incrementality results, geo tests, and media audits. The problem is that they all say different things. Platforms inflate to justify pricing. Agencies present what keeps the account. Finance trusts none of it. The room spends six weeks debating what to believe while optimization windows close and budgets get held.
From conflicting signals to one decision-ready output
360-degree intake
Platform exports, MMM outputs (Meridian, Robyn, Nielsen, custom), MTA data, incrementality tests, geo experiments, media audit findings, strategy context, and any other inputs your team produces. Everything in, nothing replaced.
Calibrate, reconcile, distill
The five-factor calibration chain reconciles conflicting signals from every source. Adjusts for attribution windows, cross-channel overlap, baseline effects, and incrementality. Harmonizes many angles into one coherent picture. Always deflates, never inflates.
Decision velocity
One calibrated output, structured for every stakeholder. CFO gets the trace record. CMO gets the narrative. Agency gets the proof point. Six weeks of debate becomes one meeting. Every claim traceable to source in under five seconds.
Architecturally incapable of producing a flattering number
Evidence Firewall
Python computes every metric. AI narrates pre-computed results. The two never cross. The system cannot hallucinate a financial claim. This is infrastructure, not policy.
MOAT Constraint
Calibrated ROAS is always less than or equal to platform ROAS. Enforced in code at every export gate. The system will not produce an inflated number — for any party, under any condition.
360-Degree Harmonization
Platform data, MMM, incrementality, geo tests, media audits, strategy context — Eichen ingests everything and reconciles it into one coherent view. It sits on top of your measurement stack. Nothing replaced. Everything harmonized.
Decision Velocity
The competitive advantage Eichen creates is speed to decision. Six weeks of reconciliation becomes one meeting. Any claim to its evidence in under five seconds. Budgets move while the window is still open.
Every claim traces to evidence
Premium Card Q4 — Calibrated Performance
National Advertiser — Multi-Platform, $12M Annual Media
The brand had platform reports from Meta, Google, and TikTok. An agency-delivered Meridian MMM. Incrementality test results. Internal strategy docs. All pointing in different directions. Six stakeholders spent six weeks arguing about what the numbers meant. The CFO wouldn't sign off.
Eichen calibrates what teams need to stand behind
Enterprise Advertisers
Platform reports, MMM, incrementality tests, geo experiments — all telling different stories. Eichen takes the 360-degree view, harmonizes every signal, and produces the one audit-ready output that gets the CFO to sign off. Decision velocity: six weeks becomes one meeting.
Agencies & Agency Groups
Your clients have platform data, their own MMMs, third-party audits, and internal benchmarks. Eichen harmonizes all of it into one calibrated narrative you can stand behind. No more revise-and-resend loops. Same evidence standard across every client, every QBR, every renewal.
Measurement & Audit Platforms
You have the model, the panel data, or the audit findings. Your clients have five other data sources that need to reconcile with yours. Eichen is the harmonization and narrative layer that distills everything into one board-ready output. White-label or co-branded — your methodology, Eichen-calibrated.
