# Divisio > No-code customer segmentation and clustering for marketing teams. Upload a CSV, pick the variables that matter, run pattern detection (K-Means), DBSCAN, or an RFM template, and turn the resulting segments into plain-English business rules, AI personas, or exportable code. Divisio reads CSV, XLS, or XLSX files up to 100 MB and lets you filter rows before clustering. Results show as an editable heatmap summary plus scatter, box, and histogram charts. On the Pro plan it also generates AI variable suggestions, AI persona cards, and business-rule exports you can paste into HubSpot, Klaviyo, Braze, or any tool that takes a filter. There is a free tier; Pro is €9.99 per month. All processing is in-memory and uploaded files are never stored. ## Product - [Divisio app](https://divisio.co/): Upload a CSV, pick variables, and get named customer segments in minutes, with no code and no data team. - [Privacy policy](https://divisio.co/privacy): How your data is handled; uploaded files are never stored. - [Terms of service](https://divisio.co/terms): Terms of use. ## Blog - [Divisio blog](https://divisio.co/blog/): Real marketer use-case stories on customer segmentation and clustering. - [RSS feed](https://divisio.co/blog/rss.xml): Full-text feed of new posts. ## Featured guides - [Free customer segmentation, start to finish](https://divisio.co/blog/pattern-detection-carriage-coffee/): A solo founder finds five customer segments on the free tier. - [RFM segmentation without code](https://divisio.co/blog/rfm-wizard-thread-and-loom/): Turning a raw orders export into Recency, Frequency, and Monetary segments. - [DBSCAN vs K-Means](https://divisio.co/blog/dbscan-tindo-marketplace/): When density-based clustering surfaces the outliers round segments hide. - [Turn segments into AI personas](https://divisio.co/blog/ai-personas-pinnacle-fitness/): Statistical clusters become named personas stakeholders can act on. - [Export segments to HubSpot without SQL](https://divisio.co/blog/business-rules-export-northwind/): Business rules export as readable IF/THEN logic. ## Optional - [Blog sitemap](https://divisio.co/blog/sitemap-index.xml): Index of all blog URLs. - [Site sitemap](https://divisio.co/sitemap.xml): Index of all site URLs.
