Covextra Exchange
The order book for AI compute: requests for proposals from buyers, binding quotes from providers, matched on the constraints that matter and settled on attested evidence.
The trusted execution layer for AI compute
A new frontier stack for enterprise AI compute.
Covextra brings verifiable governance and GPU mutualisation together, so enterprises can run AI agents and other sensitive workloads on the compute they need, with proof of where and how every workload ran.
Verifiable governance
Workloads run in confidential computing environments, with attested evidence of where and how they ran.
GPU mutualisation
Capacity from independent providers, pooled on one exchange and priced in real time.
Orchestration for AI agents
Every workload placed by policy: jurisdiction, certification, cost, and performance.
Why now
AI compute is bought on trust. It should be bought on evidence.
Enterprises that want to run AI on their most sensitive data have to take a provider's word for where it runs, who can see it and what they are paying for. Providers with capacity to spare have no common market in which to offer it on those terms.
Confidential computing changes what can be proven. Covextra builds the market on top of it: requirements stated precisely, capacity offered against them, and a workload that carries its own evidence.
How it works
From a requirement to a settled contract, with evidence at every step.
- 01
The buyer states the requirement
Model, throughput, jurisdiction, certifications, confidential computing and service level go into one request. Each constraint is marked as a must or a preference, so nothing is silently dropped.
- 02
Providers answer with binding quotes
An agent in each provider’s data centre knows its own capacity and energy cost, and answers the requests it can meet with a price it will honour.
- 03
The workload runs where it was promised
The accepted quote is deployed into a confidential computing environment, which proves by attestation what is running and where.
- 04
The evidence settles the contract
Payment is held until the instance is attested as specified, and usage is metered against the quote. The record that settles the contract is the one both sides can check.
The stack
One layer between the buyer and the hardware.
Covextra sits above the infrastructure and below the workload. It places each job by policy, runs it where it can be proven, and returns the evidence to both sides.

AI agents, inference, fine-tuning, sensitive data pipelines

Who it is for
Built for the parties who have to trust each other least.
Enterprise buyers
Run AI agents and sensitive workloads on the compute they need, with proof that the data stayed where the policy says and that no operator could read it.
Compute providers
Fill idle GPU capacity with workloads that fit it, priced against your own costs, and get paid against evidence rather than disputes.
Public sector and defence
Place workloads under jurisdiction and certification constraints that are checked by the hardware, not stated in a contract alone.
Products
What we are building.
Covextra Harness
An agent workspace whose agent, model and tools each run in an attested confidential environment, reached from the browser over a channel the operator cannot read.
Launching 2027.
We are working with a small group of buyers and compute providers ahead of launch. If you would like to be one of them, write to us.
