GRUENCY / Technical advisory
Independent technical advisory
GRUENCY reviews workstation configurations, quotes and technical plans and reports its findings in writing. It does not resell hardware, so its advice is independent of any sale.
What is reviewed
Configurations, thermal designs and methodologies, before purchase, after a failure or when a plan needs a second opinion.
- Pre-purchase configuration audits for workstations, servers and render nodes
- PCIe topology and thermal analysis of existing machines
- GPU compatibility and power-delivery reviews
- Damage assessment and failure analysis
- Quote reviews covering specification and pricing logic
- Second opinions on models, data work and technical plans
How it works
- Brief: a short call or written summary of the machine, quote or plan
- Fixed scope and fixed price, agreed before work starts
- Written findings with reasoning, followed by a call to discuss them

Questions about advisory
Can you review a quote I received from a supplier?
Yes. This is a common request. The review covers topology, thermals, component choices and pricing logic, and states in writing which parts are sound and which need changing.
Does this work remotely?
Usually, yes. Configurations, logs, photographs and quotes can be reviewed remotely. Findings are delivered in writing with a follow-up call, worldwide.
What does an audit cost?
The scope and price are fixed after a short brief, before work starts.
