Prior to Capgemini, he worked as a software developer at Calyon Corporate & Investment in 2013. During his time at Capgemini, he was involved in building optimization software to reduce costs of electricity transport for ENEDIS, a project relating to costs amounting to approximately €3 billion per year.

In 2021, Rapilly co-founded Moby Analytics alongside Dimitri Kassubeck and Clément Sengelen. The company is based in Paris, France. Rapilly serves as CTO, overseeing the technical development of the platform. His technical interests include Python, Java, Angular.js, SQL, and Microsoft Azure.

Moby Analytics

Moby Analytics describes itself as the first AI-native agentic platform built specifically for financial auditors. The company addresses the problem that auditors spend a significant portion of their working hours on repetitive, low-value tasks such as document retrieval, manual figure-checking, and PDF review. The platform allows auditors to create custom AI agents using natural language prompts without any programming knowledge. These agents can be configured to perform tasks such as extracting data from invoices, validating journal entries, and summarizing discrepancies, and can be deployed at scale across audit workflows.

The platform integrates with SharePoint, synchronising automatically with auditors' existing document storage. It constructs automated workflows from auditors' existing work papers and provides traceable results, allowing auditors to verify the AI's methodology. Moby Analytics emphasises transparency, stating that all results are traceable and that the methods remain under the auditor's control.

Moby Analytics was part of Y Combinator's Spring 2025 (X25) batch and was among ten French-founded startups selected for that cohort. As of 2025, the company has four employees.
