Sweden’s laundry tech firm Mimbly secures €3M to expand its water-reuse technology

Gothenburg-based cleantech company Mimbly has raised €3M in funding to support its laundry technology and expansion plans.

Gothenburg-based Mimbly, a Swedish cleantech company, has raised SEK 33M (€3M) in new funding to accelerate its mission to make laundry sustainable.

The round included participation from new and existing investors, such as Electrolux Professional Group, Almi Invest, Länsförsäkringar Göteborg Bohuslän, and several family offices focused on sustainability-driven investments.

Mimbly operates within the cleantech sector, focusing on water reuse for laundry systems. It was established in 2016 by Isabella Palmgren, Nicolas Maxant, and Emil Vestman.

The company’s primary system, called the Mimbox, carries a patent and functions as an external unit connected to washing machines. It collects wastewater from the machines and runs it through a filtration process that removes particles larger than 50 microns. The water is then tested to determine whether it meets the standard for reuse. Once approved, it is disinfected and stored for up to 24 hours before being circulated back for subsequent wash cycles.

When a new cycle begins, the Mimbox supplies the filtered water to the machines and supplements it with fresh water when necessary. The system also traps microplastics, which are removed after roughly 2,000 litres of water have passed through – usually once a week.

Mimbly reports that the Mimbox allows reductions in water and energy use. It enables water reuse of up to 70 per cent, captures about 90 per cent of microplastics above 50 microns, and conserves as much as 30 per cent of energy by recovering heat from greywater.

The system integrates with a digital service known as Mimsights, which compiles operational data for environmental, social, and governance documentation and compliance reporting.

Mimbly collaborates with facility managers, housing providers, hospitality operators, and smaller laundry setups. These clients employ the Mimbox to lower resource consumption while keeping their laundry processes unchanged.

The company’s technology has been adopted by organisations such as Coor Service Management, ISS, Sodexo, and Einar Mattsson.

According to Dagens Industri, the company has previously raised SEK 16M in funding in 2024. It reported a turnover of about SEK 7M and a loss of SEK 12.1M in 2024, compared with a turnover of SEK 10.3M and a loss of SEK 18.9M in 2023.

Capital utilisation

Mimbly will use the funds to expand the reach of its water-reuse system, the Mimbox, and to scale its technology for broader deployment. The company aims to strengthen its position in current markets while entering new ones.

Dagens Industri reports that Mimbly has recently introduced updated hardware as part of its product development efforts. CEO Isabella Palmgren stated that the company is targeting profitability by the end of 2026.
