Gigawatt-scale AI compute, built and operated end to end
FluidStack designs and builds large AI data centers, including high-density campuses with significant per-site power capacity, rather than reselling capacity from other clouds.
Clusters are architected for large-scale model training and inference, with high-bandwidth interconnect and orchestration suitable for distributed workloads.
The company develops off-grid solar and recirculating closed-loop cooling, treating power and water efficiency as core engineering problems.
Smart hands, cluster provisioning and operations support let research teams focus on models while FluidStack runs the physical and orchestration layers.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.

#1
SpecialistDelivers developer-first serverless endpoints optimized for generative media models rather than general-purpose infrastructure.

Offers flexible on-demand GPU rentals and serverless endpoints, but lacks FluidStack's ultra-scale enterprise GPU clusters.
SpecialistVisual builder tailored specifically for custom AI agents, but less versatile for standard non-AI data synchronization tasks.

SpecialistFocuses on optimized serverless inference APIs and managed model hosting rather than raw cluster rentals.
SpecialistBuild GTM systems that turn data into revenue
Delivers peer-to-peer GPU rental marketplaces for lower-cost experimentation, though with less enterprise infrastructure predictability.
SpecialistProvides serverless Python container execution for cloud jobs, but lacks raw multi-node cluster provisioning controls.
Provides dedicated NVIDIA GPU clusters and managed cloud infrastructure, competing directly on enterprise-grade training workloads.

Free / Open-sourceDistributed GPU cloud that orchestrates the world's idle consumer GPUs

SpecialistUtilizes proprietary wafer-scale processors for extreme training speeds, differing from standard NVIDIA GPU cluster setups.
SpecialistAI-powered workspace generating automated workflows from prompts, but less focused on deep multi-system data synchronization.
