Opper AI raises $3M to bridge the gap between AI demos and production deployment

Swedish AI infrastructure startup Opper AI has secured $3 million in pre-seed funding led by Emblem and Luminar Ventures, with participation from Greens Ventures, as the Stockholm-based company launches its Task Completion API to make AI-powered features production-ready and reliable for developers.

Founded in 2023, Opper AI addresses the gap between fragile prototypes and robust production systems. While developers can quickly build AI demos with simple prompts, scaling these into reliable, maintainable applications remains complex and error-prone.

Opper AI focuses on this by shifting from traditional prompt engineering to structured task definitions. Instead of manually crafting prompts, developers define tasks using JSON contracts that specify inputs, expected outputs, and success criteria. Opper's platform then handles prompt optimization, model selection, retries, and fallbacks automatically, ensuring consistent results across different AI models and scenarios.

The platform provides access to 80+ leading AI models through a single API, offering intelligent routing to the best model for each task with automatic fallbacks when needed. Built-in evaluation mechanisms and feedback loops continuously improve output quality, while comprehensive observability features provide full visibility into model usage, performance, and costs for debugging and compliance.

This infrastructure-first approach enables developers to build AI assistants, agents, chatbots, and backend workflows that work reliably in production environments. As AI adoption accelerates across enterprises seeking dependable solutions rather than experimental demos, Opper AI's focus on making AI infrastructure as reliable as established platforms like Stripe positions them at the forefront of the next wave of AI tooling.
