## Keywords

SoGPT, Société Générale, Copilot, Microsoft, build vs buy, AI capital, digital sovereignty, AllianzGPT, orchestration, enterprise AI, Europe, GENIAL

## Authors

Erwan Simon

## Ton

Profile: LinkedIn opinion article, strategic and polemical register, perspective of the CEO of a French AI startup (GENIAL).
Style: Engaged tone with a provocative thesis ("false debate"). Argumentative structure distinguishing interface vs infrastructure. Uses concrete examples (SoGPT, AllianzGPT). Geopolitical warning about European sovereignty. Conceptual definitions (AI capital). Target audience: CIOs, CDOs, executives of large European companies, strategic decision-makers.

## Pense-betes

- **Context**: Société Générale abandons SoGPT in early 2026 to adopt Microsoft Copilot
- **Central thesis**: The real issue is not build vs buy but "who owns the business intelligence built with AI"
- **Framing error**: Comparing ChatGPT/Claude to Office (Word, Excel) = fundamental misunderstanding
- **ChatGPT/Claude**: Infrastructure enabling custom business applications, not a finished product like Word
- **SoGPT failure**: Not the concept but the execution - generic interface disconnected from banking operations, without strategic evolution
- **Copilot limitations**: Good for generic tasks, struggles with specific business processes (ERP queries, compliance workflows)
- **Copilot problem**: Post-pilot adoption drops (ROI hard to measure, data governance, unintended exposure)
- **AllianzGPT model**: Platform orchestrating multiple components (Azure OpenAI + Claude), internal system connectors, decision traceability for regulated industries
- **AllianzGPT advantage**: Preserves organizational assets independently of the vendor, enables model change without loss of capabilities
- **AI Capital definition**: Set of encodable business knowledge - documented processes, business rules, explicit tacit expertise
- **Sovereignty risk**: "Europe lost cloud sovereignty. Repeating this mistake with AI = outsourcing the capacity to generate AI value"
- **Recommendations**: Distinguish interface/infrastructure, demand specificity, adopt iterative product thinking, retain orchestration control
- **Underlying stake**: Will European companies build indigenous AI capabilities or become permanent consumers of US systems

## RésuméDe400mots

Erwan Simon, CEO of GENIAL, reacts to Société Générale's decision to abandon its internal tool SoGPT in early 2026 to adopt Microsoft Copilot. He argues that this build vs buy debate constitutes a false framing that masks the real strategic question: who owns the business intelligence you build with AI?

The article denounces the error of comparing ChatGPT or Claude to office software like Word or Excel. Unlike these finished products with fixed functionality, AI systems are both consumer interfaces and APIs enabling custom business applications. They are infrastructure, not commodities.

Simon analyzes SoGPT's failure not as a validation of the buy model, but as an execution error: a generic chat interface disconnected from banking operations, without a continuous evolution strategy. The error was not building in-house, but creating a product with no operational anchoring.

Copilot has its own limitations. Useful for generic tasks, it struggles with specialized operations such as ERP queries or compliance workflows. Many deployments plateau after the initial pilots due to difficulties measuring ROI, governance issues, and unintended data exposure via existing permission structures.

The author cites AllianzGPT as a successful alternative model. Allianz built a platform, not just an interface, orchestrating multiple components: multiple language models (Azure OpenAI and Anthropic's Claude), connectors to internal systems, and full traceability of decisions for regulatory compliance. This architecture preserves organizational assets independently of any single vendor.

Simon defines the concept of "AI capital" as the set of encodable business knowledge: documented processes, business rules, historical decisions, tacit expertise made explicit. It is this asset that creates a durable competitive advantage.

The article concludes with a warning about European sovereignty. Europe lost cloud sovereignty in the 2010s by migrating to AWS, Azure, and Google. Repeating this mistake with AI means outsourcing the capacity to generate AI-driven value to American competitors. The fundamental question: will European companies build indigenous AI capabilities, or will they become permanent consumers of intelligence systems controlled by the United States?
