About VoltageGPU — The Decentralized AI Cloud

VoltageGPU provides affordable GPU cloud computing and AI inference, powered by Bittensor's decentralized network.

Our Products

  • GPU Compute (Subnet 51 — Lium): Rent RTX 4090, A100, H100, H200, B200 GPUs on demand
  • AI Inference (Subnet 64 — Chutes): 140+ AI models, OpenAI-compatible API, per-token billing
  • Fine-Tuning (Subnet 56 — Gradients): Train custom LoRA adapters on any HuggingFace model
  • Confidential Compute (Subnet 4 — Targon): Intel TDX encrypted GPU enclaves

Our Mission

We believe GPU access shouldn't require a six-figure AWS contract. VoltageGPU democratizes AI infrastructure by building on Bittensor's decentralized protocol — lower costs, no single point of failure, scales with the network.

Company

VOLTAGE, SIREN 943 808 824, France. Founded 2024 by Julien Aubry. Built on Bittensor decentralized infrastructure with 200+ GPUs, 140+ AI models, and 500+ miners across 4 subnets.

Affordable GPU Cloud, Powered by Bittensor

VoltageGPU aggregates GPU supply from 4 Bittensor subnets to deliver GPU compute, AI inference, fine-tuning, and confidential compute — at a fraction of hyperscaler costs.

Our Mission

We believe GPU access shouldn't require a six-figure AWS contract or a three-month procurement cycle. VoltageGPU exists to democratize AI infrastructure — making enterprise-grade GPUs accessible to every developer, startup, and research team in the world.

By building on Bittensor's decentralized protocol, we tap into a global network of GPU miners instead of building our own data centers. This means lower costs (no CapEx), no single point of failure, and an infrastructure that scales with the network — not with our fundraising rounds.

Our vision: a world where spinning up 8x H100 GPUs is as simple as calling an API, where AI model training costs dollars instead of thousands, and where sensitive data can be processed without trusting any single party.

What We Do

How It Works

VoltageGPU is a reseller and aggregator built on top of the Bittensor decentralized AI network. We source GPU capacity from 4 specialized subnets, apply our infrastructure layer (billing, API, SSH, templates, monitoring), and deliver it through a unified platform.

Standard GPU pods — RTX 4090, A100, H100, H200
Chutes SN64
AI inference — 140+ models, OpenAI-compatible API
Gradients SN56
Fine-tuning — SFT, DPO, Image LoRA on decentralized GPUs
Targon SN4

Julien Aubry

Solo Founder & CEO

The problem: In 2024, Julien saw developers and startups locked out of serious GPU infrastructure. AWS required six-figure commitments, GCP had months-long waitlists for H100s, and Lambda Labs was perpetually sold out. Meanwhile, thousands of GPUs sat idle across decentralized networks with no user-friendly way to access them.

The Bittensor thesis: Rather than raising millions to build data centers, VoltageGPU taps into Bittensor's decentralized protocol — a network where GPU miners are economically incentivized to provide reliable compute. This means VoltageGPU can offer H100 and B200 GPUs at 40-60% below hyperscaler pricing without owning a single rack. The supply scales with the network, not with fundraising rounds.

What makes it different: VoltageGPU is not just a reseller. It's an infrastructure layer that unifies 4 Bittensor subnets (compute, inference, fine-tuning, confidential compute) into a single platform with billing, SSH access, API endpoints, Docker templates, and monitoring. One account, one API key, access to the entire network.

The vision: GPU access should be as simple as calling an API. Julien is building VoltageGPU to become the default interface between developers and decentralized GPU infrastructure — starting with Bittensor, expanding to every network where spare compute exists. The goal: make GPU scarcity a thing of the past.

What We Stand For

Transparent Pricing

No hidden fees, no egress charges, no lock-in. Per-second billing. You see the price, you pay the price.

Decentralized by Design

Our infrastructure runs on Bittensor — no single point of failure. GPU miners are incentive-aligned through proof-of-work consensus.

Open Standards

OpenAI-compatible API, standard Docker containers, SSH access. No vendor lock-in, no proprietary formats.

Security First

TLS 1.3, AES-256, container isolation, Confidential Compute with Intel TDX. Your data, your control.
