Daniel Kjorberg Siraj
About Daniel Kjorberg Siraj
Daniel Kjørberg Siraj is a Norwegian business leader based in Oslo. He studied law at the University of Oslo. He joined OBOS in 2004 as a business developer and became group CEO in 2015. OBOS is a Norwegian housing co-operative and developer that describes itself as one of the largest homebuilders in the Nordic region.
He stepped down after about twenty years at OBOS, the last ten as CEO. He has since described himself as self-employed and as managing director of DKS Consulting, which focuses on strategy and leadership and board work. Public listings show board roles at NCC AB since 2023 and at Veidekke from 2018 to 2023.
Siraj's public startup investments so far are in construction technology. He joined the Volve seed round in August 2026. He is also named as an angel investor in Solvera's $6.3M pre-seed round, which Seedcamp led. Solvera describes itself as rebuilding the engineering firm, from requirements and constraints to construction-ready design.
A Norwegian business outlet reported that Volve was his first startup investment. It also reported that he dislikes the label "angel investor". No check sizes are public.
Volve is an Oslo company founded in 2024 by Herman Smith, Abyl Ikshanov and Alf Jørgen Dovland. It builds an AI platform that reads full tender and contract packages. The platform maps how scope, requirements and risks connect, and it helps contractor teams decide whether to bid and how to price. Its $3M (NOK 30M) seed round was led by Skyfall Ventures. J12, Norrsken Evolve, OBOS Ventures, Antler and StartupLab also took part.
In Volve's announcement, Siraj said the company has built a tool that delivers concrete business value here and now.
Both known investments are early-stage (pre-seed and seed) in construction and building technology, and both are European. Siraj's own career is in housing development and construction, so founders in that space will find the most overlap with his experience. He has not published a thesis, a check size or a stage preference.
