Background
Sigve Bertheussen (born 1969) is the founder, Managing Partner, and Chairman of the Board of CEFO Invest AS, a venture development and investment firm headquartered in Harstad in northern Norway. He describes himself as a serial entrepreneur with roughly 25 years of experience building companies in western and northern Norway, and he established CEFO as a vehicle to channel that operating experience, capital, and network into other founders' businesses.
He holds an MBA from the Norwegian School of Economics (NHH) in Bergen and an MBA from HEC Paris (École des Hautes Études Commerciales). The broader CEFO team is described as drawing on backgrounds in management consulting, finance, and private equity/venture capital, educated at leading business schools in Norway and Europe and at Ivy League institutions in the U.S.
CEFO Invest was originally founded in 1994 and relocated its primary operations to northern Norway in 2010, reflecting Bertheussen's conviction that the region holds "vast potential" for value creation benefiting owners, employees, and local communities. He runs the firm alongside several family members and partners — Asle Bertheussen (Senior Partner), Espen Bertheussen (CFO), and Kristin Bertheussen (Office Manager), among others — making CEFO effectively a family-anchored investment house. Norwegian business registries list Bertheussen as holding multiple board and management roles across companies and as a shareholder in several Norwegian entities.
Investment Thesis & Focus
- Invests as an active, hands-on owner rather than a passive financier: CEFO contributes "capital, competence and network," engaging operationally in technology, product, and market development and best-practice implementation.
- Backs companies across the full lifecycle — early-stage startups needing first capital, scaling firms needing growth equity, and mature businesses pursuing new value creation.
- Sector emphasis on industry, life science, retail, and ICT, per his own stated focus.
- Strong regional thesis: a deliberate concentration on Northern Norway, viewing it as an under-tapped region with large upside for business owners, employees, and communities.
- Looks to partner directly with entrepreneurs and business owners, and is also open to working alongside co-investors.
Notable Investments
- CEFO Invest does not publicly disclose a named portfolio on its website or in aggregator databases (PitchBook lists no confirmed transactions). Specific portfolio companies could not be verified from public sources.
- Bertheussen's role as Chairman and Managing Partner, combined with his multiple registered board and shareholder positions in Norwegian companies, indicates an actively managed but privately held set of holdings rather than a published fund portfolio.
