Opper AI, the Task-Completion API ensuring generative AI delivers in real-world production, today announced its acquisition of FinetuneDB, a leading fine-tuning platform for creating custom large language models (LLMs).
The deal brings FinetuneDB’s dataset curation and training workflows into Opper’s reliability stack - shortening the path from user feedback to task-optimized models, and furthering Opper’s mission to make autonomous AI agents reliable at scale.
As part of the acquisition, FinetuneDB co-founders Felix Wunderlich and Farouq Aldori will join Opper’s leadership team as Chief Growth Officer and Chief Technology Officer, respectively. FinetuneDB will remain available to customers during a limited transition period, with Opper communicating all updates directly.
“We believe the best model for a task is a model tailored for that task,” said Göran Sandahl, co-founder and CEO of Opper AI. “By joining forces with FinetuneDB, we are strengthening our ability to capture real-world data from completions and deliver reliability that unlocks the next generation of AI agents.”
“FinetuneDB was built to make fine-tuning AI models fast and straightforward,” said Felix Wunderlich, co-founder of FinetuneDB. “Together with Opper, we’ll power a future where autonomous agents can be trusted to deliver consistent results at scale.”

“Reliability unlocks scale. This acquisition brings Opper a step closer to a full suite that lets teams move beyond prototyping and run agents in production,” added Guillaume Durao, General Partner at Emblem, one of Opper’s early backers and one of the first investors in Loveable.
The acquisition comes at a pivotal time for the AI industry, where reliability and fine-tuning are fast becoming competitive battlegrounds. In recent months, leading AI companies have accelerated acquisitions of specialist platforms and top technical talent to strengthen their foundations in autonomy and customization. By bringing FinetuneDB into its stack, Opper positions itself firmly among the companies shaping the future of trustworthy, production-ready AI.
The acquisition signals Opper’s growing ambition in the rapidly accelerating autonomous agent space, where reliability remains a key barrier to adoption. Opper confirmed that new product releases in autonomous AI agents will be announced in the near term.
FinetuneDB acknowledged and thanked its early investors, including Antler and EWOR, for their trust and support.
