Software Development Budapest 201–500 employees Founded 2006 Privately Held

Sonrisa is a Budapest-based software services firm built around Java, C#/.NET, and enterprise backend infrastructure—classic B2B IT outsourcing. But the tech-stack shape reveals a sharp pivot: they're actively adopting OpenAI, Anthropic, Azure OpenAI, AWS Bedrock, and orchestration tools like LangChain and LlamaIndex while their project list centers on AI-powered applications, RAG pipelines, and agentic workflows. This signals a deliberate repositioning from traditional custom development toward AI-augmented enterprise solutions.
