Case studies

Real workloads, real bills, real receipts. We publish case studies once a customer is comfortable putting their name and their numbers on public record.

If you're running a workload on Joule Cloud and want to be a case study (in exchange for ongoing credits), write to [email protected].

Published

• An LLM SaaS company moving 40M inference calls / month off OpenAI
• An EU health-tech storing 80 TB of patient analytics, jurisdiction-pinned

In flight

• An ed-tech using Meet + Object Store for class recordings — publishing summer 2026
• A regional government department audit-trail use case — publishing autumn 2026
• A scientific computing workload — molecular dynamics on the mesh — publishing TBC

Common shapes

• The lift-and-shift from a hyperscaler. Compute + Object Store + Postgres. 25-45% lower bill, same redundancy, joule + carbon attribution on every line.
• The greenfield inference workload. OpenAI-compatible API, mid-bell-curve traffic patterns, energy-budgeted to keep runaway loops from eating the month.
• The EU-residency-bound workload. Region pinned to eu-fi or eu-de, signed receipts for CSRD and AI-Act disclosure.
