Diffly raises €1.7M to become the European leader in Win-Loss Analysis

Diffly, a French startup specializing in the collection, analysis, and utilization of post-sales cycle feedback (win-loss analysis), announces a €1.3M funding round led by 360 Capital, supplemented by €400K in financing from Bpifrance. This funding aims to strengthen the technological platform, structure marketing development, and support the scaling of its SaaS solution for B2B sales and marketing teams.

A new approach to sales performance

Why do we win some deals... and lose others? What truly influenced the buyer’s decision? Were we too expensive, too slow, or not clear enough? Few companies can reliably answer these questions. Too often, analysis is limited to CRM fields, which are incorrect 90% of the time, according to a Gartner study. To address this, win-loss analysis offers a structured, objective, and continuous approach to understanding the real reasons behind every win or loss and sustainably improving sales performance.

Founded in 2023 by Julien Cohen-Roussey, Anne-Sophie Clément, and David Guillermain, the team behind two major French tech successes, Multiposting (acquired by SAP) and Javelo (acquired by PSG Equity), Diffly aims to transform every sales experience into genuine levers for growth and knowledge for B2B companies.

In a context where most companies do not know exactly why they win or lose business opportunities, and where B2B buyers spend only 17% of their purchasing journey in direct interaction with a salesperson, with the rest done autonomously or with peers, it has become essential to better understand what truly drives purchasing decisions.

Diffly combines artificial intelligence and tailored support to gather feedback from buyers, both prospects and customers, at scale. Through a unique blend of AI and personalized services, Diffly enables a deep understanding of the reasons behind every purchasing decision, on a large scale.

Fully integrated with leading CRMs, the platform collects and analyzes in-depth feedback from prospects and customers, derived from qualitative interviews conducted by independent win-loss experts and automated questionnaires.

Strong traction and European ambition

Already adopted by around fifty companies, including Adobe, Contentsquare, Crown Bioscience, Didomi, and Illicado, Diffly’s solution helps executives, sales, and marketing teams better understand their positioning, identify differentiation levers, and optimize their sales cycle. According to a Gartner study, companies that implement a rigorous and continuous win-loss analysis process see an average 50% improvement in their conversion rates.

This funding will enable Diffly to consolidate its technological lead, structure its offering for broader deployment, and continue building a strong brand around a strategic yet underutilized topic. Hosted within the Village by CA accelerator, the company also benefits from the support of several experienced business angels. It aims to have around a hundred references by the end of 2025 and plans to double its workforce in the coming months, with a clear goal: to become the European leader in this still emerging but high-potential market.

"We built Diffly based on a simple observation: companies have little reliable information about the reasons that truly influence the decisions of their prospects and customers. Our mission is to provide business leaders with a clear, structured, and continuous understanding of their sales performance. With 360 Capital’s expertise in supporting high-growth companies, we will be able to expand our impact and help more companies improve their sales effectiveness."‍
