Dealspec UG 🇩🇪

Interim CTO for Mezler UG, the company behind DealSpec — a data- and AI-enabled toolsuite for M&A advisory and investment banking. The platform streamlines deal management, document handling, and analytics along the core parts of the M&A process.

Key technologies

• Next.js and React frontend, with TanStack Query, react-hook-form, and shadcn/Tailwind

• Drizzle ORM
• BetterAuth for session-based auth and OAuth
• Scaleway Object Storage (EU/France, S3-compatible) for file storage

AI infrastructure

Multi-provider and EU-first by design — every model call is routed to keep inference inside the EU wherever a provider supports it.

• Anthropic Claude via Azure AI Foundry in Sweden, not Anthropic's own API, specifically to keep inference in the EU
• Google Gemini via Google Vertex AI, pinned to europe-west4
• Azure OpenAI, native EU deployment
• Gateway fallback to OpenAI and others — only for models with no EU option — via Vercel AI Gateway
• Voyage AI voyage-finance-2 for finance-specialized embeddings, rerank-2 for reranking
• LangSmith for AI pipeline tracing
