Why do shoppers with a low share of wallet no longer buy from us?

And 18 to 29-year-olds?

Aged 18 to 29 · wave 1/2026 · n = 9,120 of 648,000

Reasons for buying elsewhere (multiple answers)

  4. Switching between retailers29%
  5. Too far away14%
  6. Range does not fit12%

What changes

  1. Analyse the data

    TodaySeveral waves with hundreds of thousands of rows are hard to analyse in a spreadsheet.

    With Synthexa

    Findings with sample size

    Rankings and shares from every row, always with filter, period and n.

  2. Follow up

    TodayEvery follow-up question means another analysis run in statistics software.

    With Synthexa

    Follow-up questions in the same analysis

    Switch or compare target groups without another analysis run.

  3. Pass it on

    TodayFigures from the analysis are copied into slides and tables by hand.

    With Synthexa

    Results to pass on

    As a presentation on your slide master or as an Excel table.

Bottom lineFindings you can back up with their sample size, and the next question without another analysis run.

What you can rely on

  1. Every number is checked.

    Calculations run in code, not inside the language model. Every number in a finding comes from an executed calculation and is checked against it.

    Check, example

    • Share 41%checked
    • n = 9,120checked

  2. When in doubt, Synthexa asks.

    If two variables could apply, Synthexa asks instead of guessing.

    Question back, example

    • Do you mean share of wallet or shopping frequency?

  3. The finding travels as a file.

    As a presentation on your slide master or as an Excel table, with filter, wave and sample size.

Frequently asked questions

In short

The number of respondents a result is based on, n for short. Synthexa shows it with every finding, together with the filter and period.

Which exports can Synthexa analyse?

What do I get, and in which form?
Rankings and shares with filter, period and sample size, as a presentation on your slide master or as an Excel table.
How does this differ from market analysis?
Market analysis works with market and retailer data, survey analysis with your customers’ answers. Both can be combined, also with earlier studies in the knowledge base.
How does Synthexa make sure the numbers are right?
Calculations run in code, not inside the language model. Every number in a finding comes from an executed calculation and is checked against it before it is shown.
Where is my data?
The platform is hosted in Frankfurt, and AI processing takes place in Europe. Your data is not used to train AI models.
