Tandem

Tandem is a French technology startup that provides an in-app, personal AI assistant designed to enhance user experience and product adoption. Founded in 2024 by Christophe Barre and Manuel Darcemont, the company was established at the startup studio Hexa.

The core of Tandem's offering is an AI agent that integrates directly into a company's application. This assistant helps users navigate complex features, automate setups, and complete tasks effortlessly. By providing interactive guidance and performing actions on behalf of the user, Tandem aims to convert all users into power users, thereby increasing activation rates, product adoption, and trial-to-paid conversions. The platform can ingest a company's existing knowledge base and success playbooks to provide contextual, automated, and scalable support. This allows non-technical teams to address user friction points without needing to write code.

The business model targets software companies looking to improve user onboarding and engagement. Clients include notable companies like Qonto, Aircall, and Sellsy. Tandem's system is designed to reduce user drop-off during critical setup and discovery phases by shortening the time-to-value.

In July 2025, Tandem announced it had raised a €3.2 million ($3.8 million) seed round led by Tribe Capital. The company intends to use the funds to expand its team, enhance its AI features, and establish a U.S. headquarters in San Francisco to scale its operations across more organizations.
