Celium — GPU Rental Marketplace

A GPU rental marketplace turned into one legible console — compare nodes on a map or a spec grid, rent in a single screen, then monitor utilization, billing and spend without leaving the product.

The problem

Renting cloud GPUs for training or rendering is mostly friction. The consoles that broker them bury the actual decision — which card, at what price, in which region, with how much VRAM and bandwidth — under cluttered spec tables, opaque pricing, and setup that spills across separate admin pages. Before a single model runs, a developer has to compare hardware they can't easily line up, guess at hourly cost, wire SSH keys, then go hunting for where utilization and billing even live.

The approach

I designed Celium end to end — information architecture, UX and UI — from the marketing landing page through the marketplace itself. The through-line: treat a GPU broker not as a flat list but as a decision surface. One consistent spec grammar reads the same wherever a node appears — browse card, map node, checkout summary, running pod — and browsing always sits one step from acting.
Browse — every spec lined up to compare
Browse — every spec lined up to compare
Cards lead with the three inputs that decide a rental — count, model, and $/hr — then disclose the full spec sheet beneath.
One filter rail re-cuts the set in place: price, VRAM, CPU, RAM, storage, bandwidth, interconnect, GPU model.
Rent Now rides every card, so comparing and committing are one motion.
A world map view serves teams that pick by region and latency — same spec grammar, same one-tap rent.

Operate: a running pod you can actually read

Pod telemetry — health, spend and controls on one screen
Pod telemetry — health, spend and controls on one screen
A vitals strip — spend, uptime, network up/down — rides the top with a live Running status.
Per-GPU utilization, temperature, memory and power read at a glance across the whole node.
SSH connection string, ports and template sit on the same screen as Connect / Reboot / Stop.
Billing is a fundable balance with auto top-up — so a multi-day training run never dies because the wallet hit zero.

The honest outcome

I designed a more capable marketplace than the simpler listing interface that ultimately shipped. That gap is exactly why I now stay close to implementation and QA whenever the final quality lives in the interaction details — the work stands as a complete, coherent design for a marketplace that has to stay legible while price and availability keep moving underneath it.
