UK replaces Palantir with in-house tech

This is a rare and high-profile win for "build vs. buy" in government, signaling a shift away from the expensive "embedded engineer" model favored by Palantir.

• –Replacing Palantir's Foundry with a GOV.UK-based internal system cuts multi-million pound annual licensing fees.
• –The move highlights a growing maturity in government DDAT (Digital, Data and Technology) teams to handle complex data integration.
• –Moving from a proprietary black box to in-house code allows for better customization and faster iteration on refugee safeguarding features.
• –While a success here, Palantir still holds over £600m in other UK contracts, suggesting this is a localized victory rather than a systemic trend.
