Hanhi Partners

Hanhi Partners Oy, which operates under the Duck's Back brand, offers chemical-free cleaning based on nanocoatings for surfaces. The coatings reduce porosity so that surfaces repel dirt and can be cleaned with water and a microfibre cloth. An AI-based application digitises cleaning management and communication and provides real-time data across the service chain. Installation and cleaning are carried out by a partner network of installers.

The offering is sold as three "Nano as a Service" (NaaS) packages named Value, Performance and Delivery, focused on property management and cleaning. Target customers include hotels and restaurants, healthcare, industrial and public-sector sites, and the transport sector. The company states that it is a recommended partner of MaRa ry, a Finnish association for the hotel and restaurant sector.

Hanhi Partners Oy was founded in 2023 and is headquartered in Oulu, Finland. The company states that it operates nationwide in Finland and reports up to 30–35% savings in cleaning time and up to three times faster room turnover. It also cites ISO 18184:2019 certification for its antimicrobial coatings.
