What it sells
Water-cooled GPU servers installed inside swimming pools and hotels; the waste heat becomes hot water and heating while the compute is sold to AI teams.
Business model breakdown
Buyer: who owns the budget?
UnverifiedAI teams and developers renting GPU compute; hosts (pools, hotels) accept free heating.
Trigger: what makes them buy now?
Compute buyers get more tokens per euro than traditional cloud; hosts get free heating with zero capital investment.
Workflow: what inputs become what output?
Install server racks in a facility's hot-water loop, recover heat for the host, rent GPU compute to AI workloads; pilot at Amraser Schwimmbad, Innsbruck since April 2026.
Economics: what it saves and how it charges
Serwas funds, ships and operates the server installation and pays power and internet; hosts get free heat (site claims up to EUR 60,000/year heating savings, 98% heat recovery).
Distribution: how it reaches customers
On-demand GPUs via leading cloud compute platforms (pay-per-hour, instant deployment) and reserved dedicated clusters with custom configs, SLAs and direct support.
