Inflexion

Measurement

Measure what marketing actually adds.

Platform reports disagree and attribution overstates the last click. Inflexion combines media mix modelling, incrementality testing and attribution into one view of what drives sales, then turns it into budget decisions.

The problem

Every platform marks its own homework.

Each platform credits itself for the same sales. Added together, the reports claim far more than the business actually sold.

Platforms claim 1.7 times the sales that actually happened. Budgets set on these numbers favour whichever channel sits closest to the purchase.

Our methods

Three methods, calibrated into one view.

No single method is reliable on its own. Each answers a different question, and each checks the others.

01

Media mix modelling

Statistical models of how every channel, price change and external factor affects sales over time.

AnswersWhere should budget sit across channels?
RefreshedMonthly
02

Incrementality testing

Controlled experiments, such as geo and audience holdouts, that show what a channel actually caused.

AnswersDid this activity create sales that would not have happened?
RunContinuously, on priority channels
03

Attribution and platform data

Campaign level signals used for daily optimisation, adjusted using the model and test results.

Calibrated view of performanceBudget decisions

From measurement to decisions

The same budget, allocated where it returns most.

Response curves show where each channel starts to saturate. The plan moves spend from channels past that point to those with room to grow.

What sets the approach apart

Signals most measurement misses.

Media models rarely include AI search or the retail shelf, yet both now shape sales. Inflexion measures them alongside media.

Independent of the platforms

Models are configured for each business rather than run on a platform's default settings. Open source frameworks such as Meridian are used only where they fit.

Owned by the client

Clients own their data, models and results. Methods and assumptions are documented so finance teams can review them.

Built for decisions

Every output ends in a recommendation on budget, channel or creative, reviewed with the people who make those decisions.

Our approach

From data audit to measurement that runs every month.

Four stages, each with a defined output. Most clients start with the audit.

  1. 01

    Audit

    Review data sources, current reporting and the questions measurement needs to answer.

Questions

Frequently asked questions.

How much data is needed?

Media mix models work best with around two years of weekly sales and spend data. Where history is limited, incrementality tests provide early answers while the data builds.

Does this replace attribution?

No. Attribution stays useful for daily optimisation. The model and tests correct its bias towards the last click, so it can be used with more confidence.

Is measurement independent of the media Inflexion buys?

Methods, assumptions and results are documented and shared in full, and clients own the models. That makes the measurement open to review by finance or a third party.

Can retail media be measured this way?

Yes. Retailer data, including Amazon Marketing Cloud, feeds the model and supports incrementality tests within retail media networks.
