The creator of Walmart's vibe-coding tool Code Puppy is leaving for AI startup Pydantic
The creator of Walmart's internal vibe-coding tool is leaving for AI start-up Pydantic. Code Puppy lets workers code their own software tools.
Walmart's Code Puppy creator, Michael Pfaffenberger, is departing the company to join AI startup Pydantic, according to a memo seen by Business Insider. Pfaffenberger grew Code Puppy from 1,000 users to nearly 75,000, allowing employees of all levels, from engineers to hourly store associates, to code their own software tools. The vibe-coding tool, based on the Pydantic AI library, has been used for merchandising, supply chain, and store management, among other applications.
Walmart confirmed Pfaffenberger's departure and wished him well, noting that the tool will continue to be supported by his colleagues. Code Puppy is part of Walmart's strategy to prevent potential locking into a few powerful AI providers, as it can work with multiple models from various suppliers. Pfaffenberger expressed joy at the tool's impact on users, stating that the decision to leave was difficult but right.
