Diffly

Diffly is a European win-loss analysis platform for B2B companies. Founded in 2023 and based in Paris, it collects feedback from buyers - both prospects and customers - at scale and uses artificial intelligence to analyse it, delivering real-time recommendations to sales teams on why deals are won or lost. The stated aim is to improve conversion rates and support data-driven sales decisions.

The company has three co-founders: Julien Cohen-Roussey, David Guillermain and Anne-Sophie Clement. All three are serial entrepreneurs, having previously co-founded Javelo, which was acquired by PSG Equity, and Multiposting, which was acquired by SAP. Diffly has raised €1.7m, with investors including Better Angle and 360 Capital, and takes part in the Village by CA accelerator. It is a laureate of the Wilco and Raise programmes.

Technical work at Diffly spans artificial intelligence, AI-powered recommendations, feedback analysis and sales analytics. The product combines automated analysis with tailored human support for customers. The company operates from Paris with a European focus and sits in the B2B sales software market.
