At UltiHash, we're pioneering the next generation of data infrastructure. Our cutting-edge object storage is designed for AI and Analytics applications, delivering high-performance and resource-efficiency.

For modern companies data and machine learning is at the core of their business as they implement smart and autonomous systems. Some choose to implement Retrieval-Augmented Generation or fine-tune a LLM/SLM, which both require specific training data from the company in order to generate tailor-made outputs. Efficient access to data is essential, making data storage the backbone of all AI and analytics applications.

UltiHash responds to the need of fast growing unstructured data in throughput-intensive applications with the first high-performance and resource-efficient object storage. Our proprietary deduplication algorithm built-into the storage solution minimizes the growth of storage footprints without compromising throughput.

Leading enterprises in manufacturing, telecommunications and automotive as well as pioneering AI companies have influenced the development of our solution from day 1. With the upcoming public launch of our product, we are looking to strengthen our talented development team.
