While everyone is talking about AI and hyperpersonalisation, customer segmentation might sound ‘old school’. But on the contrary: Segmentation is back, and is here to stay! In this talk, we show how we combined segmentation and machine learning (prediction) to enable personalised campaigns towards the entire customer base at Delhaize.
3. SEGMENTATION IS DEAD
AI
“SEGMENTATION IS TOO SIMPLE TODAY”
It seems that Segmentation is
too simple to tackle this
challenge. AI is more trendy…
However, AI can be too
complex, too blackbox to use
and implement…
4. “SEGMENTATION BRIDGES THE GAP BETWEEN TECH AND BUSINESS”

As a result, the surveyed customers
can already be segmented.
But what about the other 99,75%?
