Ballast Compute
GPU capacity API that runs on curtailed and behind-the-meter power worldwide.
Ballast deploys containerised GPU pods with onboard batteries at sites with power that cannot reach the grid: curtailed wind and solar farms, flared gas, oversized industrial connections.

The idea in full
- What
- Ballast deploys containerised GPU pods with onboard batteries at sites with power that cannot reach the grid: curtailed wind and solar farms, flared gas, oversized industrial connections. A single API sells interruptible training and batch inference capacity, and a scheduler built in-house checkpoints, migrates and re-prices jobs as power at each site appears and disappears. Enterprises sign up with a card and a key, and pay per GPU-hour at a rate set by the site, not by a datacentre rack.
- Why now
- The 2026 cohorts are full of the supply side of this trade and empty of the demand side: NODI Energy (YC X25) is building distributed energy infrastructure for data centers, Voxel Energy (YC W26) is doing energy independent data centers with solar and repurposed batteries, and voltiumAi and DataTherm are optimising and reusing data center energy, so the power is being assembled while no one sells it as an API.
- Wedge: first customer and entry point
- One 2 MW pod at a single curtailed wind site, sold as cheap interruptible fine-tuning capacity to three AI application companies the founders already know, on a raw scheduler with manual checkpoint hooks.
- Path to 100x
- Global AI compute spend is already a $10-100B annual market and stranded or curtailed power lets an interruptible tier price roughly an order of magnitude below on-demand rack capacity. The moat is distribution on both ends: multi-year exclusive rights to power at hundreds of otherwise unusable sites, plus being the default cheap tier inside the routers and orchestration frameworks that developers already call.
- Ceiling
- If grid power for data centers loosens or hyperscalers build their own behind-the-meter supply, the price gap compresses and Ballast becomes a low-margin reseller of hardware it financed.
- Closest real companies, as the generator saw them
- Voxel Energy and NODI Energy build the power and the buildings and sell space or electrons; Ballast never owns a building and sells compute-hours over an API, which is the layer above them. voltiumAi optimises energy inside existing data centers rather than placing workloads where power is stranded.
- Main risk
- Interruptible capacity turns out to be a niche because most enterprise AI spend is latency-bound inference that cannot tolerate migration.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
Interruptible GPU-hours at 10x below rack rates with exclusive multi-site power rights is a genuine $10B+ power-law bet.
Bootstrapper
1/5
A single 2 MW GPU pod with onboard batteries is tens of millions of financed hardware before the first billed GPU-hour.
Operator
2/5
Interruptible capacity forces buyers to rearchitect jobs around checkpointing and migration, which is exactly the workflow change enterprises refuse.
Technologist
4/5
An in-house checkpoint-and-migrate scheduler across intermittent 2 MW pods is genuinely hard systems work, though the moat leans on power contracts more than code.
Risk
2/5
Capital-heavy pods financed against interruptible demand from three known AI app companies, with site power rights as the single point of failure.
trends
4/5
Stranded-power GPU capacity matches the Compute at Sea RFS and AI infra's jump from 4% to 8% of YC S26; the window is open now.
