Opper is an AI infrastructure company founded by Göran Sandahl and Johan Gustafsson, the co-founders of Unomaly (acquired by LogicMonitor in 2020). The company has a team of seven and is headquartered in Sweden. It has launched a "Task Completion API" designed to help developers move beyond one-off prompts and fragile prototypes by providing a structured path to production AI features. Opper positions the API as a tool to remove guesswork from prompt engineering and increase reliability for chatbots, agents, and data tasks. The startup recently completed a $3m pre-seed financing to support product development and early go-to-market efforts. No revenue or user metrics were disclosed in the article.
