Best for: Ecommerce and DTC brands that want attribution and profit reporting in one tool
Klar is the attribution tool in this category that reports profit next to credit. A brand connects its store and ad accounts, and the same account then holds multi-touch attribution, a marketing mix model, geo-lift incrementality, a P&L view, cohort and retention analysis, and creative and influencer reports. That is the reason it sits at #1: one price covers the whole ecommerce measurement stack, with unlimited users and integrations.
The company is Klar Insights GmbH in Munich, and the vendor states that data is hosted in Europe and that it is ISO 27001-certified, although it names no country or provider for hosting. Core starts at EUR 200 a month and Core + Attribution at EUR 400, priced by net revenue of the last 12 months, with a 14-day free trial. The founding year is not stated on the pages checked.
What Klar does well
- Attribution, MMM and incrementality in one engine
- Profit and retention reporting in the same tool
- Published pricing with a 14-day trial
- Unlimited users and integrations
- German entity with hosting in Europe
Where Klar falls short
- Aimed at ecommerce, not B2B pipelines
- Attribution needs the higher plan
- Price scales with revenue
- Hosting country not named
Standout feature. Klar is the only tool in this category that puts a P&L view of profit next to attribution credit in the same account.
