Michael Pfaffenberger, creator of Walmart's AI coding assistant Code Puppy, is leaving Walmart to join AI startup Pydantic. Code Puppy, which has grown to nearly 75,000 users inside Walmart and is based on an open, multi-provider AI model architecture, will continue under the stewardship of a strong internal team.

This Wire brief sits within Fusion42's coverage of Enterprise Software.

◆ ◆ The Wire takeaway

Your enterprise AI tool just gained validation as Walmart proves large firms can build powerful AI coding assistants without locking to one provider. Shift your product to enable multi-model AI use and aim for broad user bases across departments.
