long-term equity in technology companies
patient capital paired with engineering perspective. BLACKVORTEX AS takes positions in technology companies where we have conviction — and stays in them long enough for that conviction to be tested.
horizon
10y+
we measure ownership in decades, not quarters. compounding requires patience most cap tables don't have.
concentration
narrow
a small number of positions, deeply understood. we'd rather own less of what we believe than more of what we don't.
scope
technology
platforms and tools where engineering quality compounds — infrastructure, security, marketplaces.

[private]02 — about
a small Norwegian company doing two things well
BLACKVORTEX AS is a Norwegian private limited company based in Gjøvik, Innlandet. It exists for two reasons: to hold equity in technology companies for the long run, and to do consultancy work on problems we find genuinely interesting.
Both halves answer to the same standard. We work where we have conviction, and stay long enough for it to be tested. Most of the value compounds outside any single quarter.
If your team needs an extra set of hands on software architecture, engineering, or platform work — or if you're building something we'd want to own a piece of — get in touch.
03 — questions
common questions
What does BLACKVORTEX AS do?
Two things. We hold long-term equity in technology companies, and we do technical consultancy on software architecture and engineering. The holdings are the core; the consultancy sharpens our judgment and funds the positions.
Where are you based, and how do you work?
Registered as a Norwegian private limited company in Gjøvik, Innlandet. Engagements are remote-first, primarily across European time zones.
What's the holdings strategy?
Long horizon (10+ years), narrow concentration, technology sector. We take founding or early positions in companies we'd want to use ourselves and stay through compound growth, not exit cycles. Current positions: Budna Marketplace AB (founding equity, board) and TRETOEN AS / 321 (minority stake).
What kind of consultancy engagements do you take?
Software architecture, hands-on engineering alongside your team, production platforms (deployment, observability, scaling), and independent technical review of architecture or code. We're more useful on backend, platforms, and systems than on greenfield product UX.
Why both holdings and consultancy?
They strengthen each other. Equity positions keep us accountable for long-run outcomes, not short-term advice. Consulting in production gives us pattern recognition for which companies will compound.
