Why they matter

Ex-Green Mountain CEO now building a fresh Nordic hyperscale platform from scratch — a rare read on where smart Nordic colocation capital is heading next.

Background

Svein Atle Hagaseth spent roughly a decade at Green Mountain, the Norwegian data center operator, rising through senior leadership roles to CEO (2023-2026), where he helped scale the company from a regional challenger into a leading Nordic platform. In April 2026 he co-founded Heim Datacenter alongside fellow former Green Mountain CEO Tor Kristian Gyland, launching a new Nordic platform focused on sustainable, hyperscale-ready data center infrastructure across Sweden and Finland.

Call-prep brief

Background

  • Spent ~10 years at Green Mountain (Norway), rising to CEO (2023-2026); credited with scaling it from a regional player into a leading Nordic data center platform.
  • In April 2026, co-founded Heim Datacenter with former Green Mountain CEO Tor Kristian Gyland (Gyland is Executive Chairman & President; Hagaseth is CEO).

Current focus

  • Building out Heim's Nordic pipeline: West Sweden (30MW scaling to 300MW by 2029), West Finland (100MW to 130MW by 2028), and Finland's capital region (50MW to 150MW by 2030).
  • Publicly positions Heim's differentiator as execution speed and quality over capital or announcements alone.

What he cares about

  • Sustainable, scalable infrastructure purpose-built for hyperscale and HPC/AI workloads.
  • Operational discipline and delivery track record as the true competitive moat in a crowded, capital-flush data center market.

Recent moves

  • Selected as opening keynote speaker at Data Center World Europe (Vienna, Oct 13-14, 2026), signaling rising industry profile just months after Heim's launch.
  • No disclosed funding details yet for Heim — worth probing.

Potential sensitivities

  • Heim is pre-revenue/early-stage; questions on capital structure, land control, and power procurement may be guarded competitively.
  • Departure timing from Green Mountain (a scaled, established platform) to a startup may invite questions about non-competes or strategic disagreements — approach diplomatically.

Questions to ask

  1. Who are Heim's capital partners, and how is the ~280MW+ pipeline being financed?
  2. What power procurement and grid-connection strategy underpins the Sweden/Finland site selection?
  3. What specifically did he see at Green Mountain that convinced him a new platform (vs. staying) was the better vehicle to execute on?

Outreach draft

Subject
Quick call on Heim's Nordic data center build-out
Hi Svein, Congratulations on launching Heim Datacenter — the Nordic pipeline across Sweden and Finland is an ambitious and well-timed bet on the region's power and land advantages. I'm on a deal team evaluating opportunities in data center colocation and hyperscale infrastructure, and your experience scaling Green Mountain as CEO gives you a rare vantage point on what actually works in Nordic buildouts versus what just gets announced. Would you be open to a 20-30 minute call in the next couple of weeks? We'd value your read on capital intensity, power procurement, and site execution timelines in the region. Happy to work around your schedule. Best, [Placeholder Name]
