What Software Sauna does
Software Sauna d.o.o. is a Zagreb-headquartered nearshore software development consultancy founded in April 2018 by Finnish entrepreneurs Ilkka-Cristian Niemi and Timo Hakkarainen. The company sells full-stack agile software craftsmanship and, more recently, Data & AI Engineering services primarily to Nordic enterprises and scale-ups, combining Nordic business culture with engineering delivery from Croatia and the Balkan region. Service delivery is built around modern web and mobile stacks (React, Node.js, Kotlin/Spring Boot, Kotlin and Swift for mobile) on AWS infrastructure, and is executed using an Extreme Programming methodology with a Dev Advocate layer of 4 senior practitioners managing teams of 3-5 developers each.
The company operates a remote-first model supported by physical offices in Zagreb (delivery HQ), Helsinki (business development), Skopje (engineering/R&D), Køge (Denmark, opened 2024), and Oslo (Norway, opened 2021). It serves verticals including Healthtech, Fintech, eCommerce, and HR & Recruitment, with a customer roster that mixes enterprise Nordic brands (Suunto, Varjo, Wiraya, Efecte, Hotelway, Wunderdog) with startups across Europe and, since 2023, the Middle East and Africa. Pricing is quote-based across staff augmentation and custom-development engagements, with multi-year contracts.
Software Sauna has been bootstrapped and consistently profitable since inception, growing revenue approximately 2000% from 2018 to 2022 and approximately 30% year-over-year in 2025. In August 2025 it joined Witted Megacorp as a subsidiary, embedding the company within a broader Finnish technology ecosystem that already includes its early backers Witted and Reaktor. Headcount reached approximately 30 by 2024, with management comprising a CEO, Head of People Operations, New Business lead, and a team of full-stack developers and engineers.
