What Haahtela does

Haahtela is a Helsinki-based construction project management and consulting firm founded in 1975, employing 170+ multidisciplinary professionals including architects, mathematicians, programmers, engineers, and business specialists. The firm operates as both a project manager/main contractor for large-scale Finnish construction projects and a strategic real estate consultant, having led more than 200 projects worth approximately €4 billion over its history, including landmark engagements such as Finland's tallest office building (Pasilan Keskitorni for Varma/Elisa), the €300M Kesko Onnela logistics center, and the €78M EriCa Green Chemistry Park.

The company's core technology asset is Realaizer, a proprietary simulation software (rebranded from Haahtela TVD in 2024) built on 50+ years of proprietary Finnish construction data and approximately 100,000 algorithms. Realaizer models building costs, carbon footprint, and lifecycle outcomes before design begins, enabling clients to set binding cost and carbon limit values. The platform was extended in 2024 with a carbon footprint simulation module developed through a three-year Business Finland-funded research project. Haahtela distributes Realaizer through direct enterprise sales (notably Skanska and YIT Finland-wide deployments) and a growing certified partner network including A-Insinöörit, Areite, and Boost Brothers.

Haahtela generates revenue through three streams: (1) professional services fees from end-to-end project management and main contracting, (2) strategic consulting on property portfolio and project development, and (3) a recurring SaaS/licensing model for Realaizer with an associated certification and training program. The customer base spans municipalities (City of Helsinki, Oulu, Espoo), major developers and pension funds (Varma, OP, Kirkon Eläkerahasto, Aktia), large enterprises (Kesko, Kemira, Elisa, Skanska, YIT), and institutional clients (New Children's Hospital, Hanken). The firm is family-owned, with Professor Yrjänä Haahtela as CEO and Pyry Haahtela leading Realaizer business operations, and operates exclusively in Finland with disclosed 2024 turnover of €24.9 million.
