Arrow Lake was founded in 2016 with a clear vision and ambition of creating the world’s most efficient ozone generator to enhance water- and air treatment for our shared sustainable future. Thanks to the advanced core technology, superior design, and unique processes, the Company’s product has proven to increase the treatment efficiency by approx. 20 per cent, compared to existing alternatives. Consequently, Arrow Lake’s ozone generators can improve water- and air treatment while, at the same time, reducing energy consumption. Ozone has proven to be an effective, powerful, yet sustainable method to treat water because of its active elimination of contaminations and absence of harmful residuals. These properties make ozone attractive for, e.g., the food and beverage industry, aquaculture, industrial and municipal treatment processes.

När du sparar i Proethos Fond investerar du enligt ett nytt ekonomiskt tänkande. Vi kallar det klimatkapitalism. Den bygger på insikten om att det som är bra för vår planet också är bra för ekonomin. Proethos Fond investerar därför uteslutande i företag som bidrar till klimatkrisens lösning. Ditt sparande placeras inom fyra olika områden - förnybar energi, energieffektiviseringar, hållbara transporter och hållbar livsstil. Alla fyra är avgörande för att världen ska komma till rätta med klimatproblemet – och därmed är de också bra ekonomiska investeringar. Det är i dessa gröna företag och branscher som tillväxten, lönsamheten och framtiden finns, både idag och imorgon. Tänk på att placeringar i fonder/värdepapper alltid medför en risk. Historisk avkastning är ingen garanti för framtida avkastning. Proethos AB är ett företag registrerat i Sverige (Org. nr 559032-3514). Fondtjänster tillhandahålls av AIFM Capital AB (Org. nr 556737-5562) som står under tillsyn av Finansinspektionen.

Vi förverkligar fysiska produkter! Det finns många idéer därute som både kan och borde realiseras. Men det är få människor som kan komma på en idé, ta fram en färdig produkt och göra den tillgänglig på marknaden. På grund av processens komplexitet förblir många innovationer bara idéer eller fallerar på grund av okunskap om produktutveckling och marknadsanpassning. Tillsammans tar vi fram en prototyp, finansierar och hjälper dig med allt för att ta produkten till marknaden. Oavsett vad du behöver hjälp med så löser vi det. Nedan visar vi exempel på de kompetenser vi idag kan bistå med.
