## Platform

- [Greyfield Data & Compute](https://greyfieldstrata.com/platform/data-compute/): Data and computing power for people, systems and AI agents: regulatory and market information ready to consume, and calculations that return not only the result but its explanation. Through API, MCP or the command line.
- [Greyfield Hub](https://greyfieldstrata.com/platform/greyfield-hub/): Your whole business in one place, connected to what you already have. Greyfield Hub becomes what your organization needs: a reporting portal, the place where a process is managed, or the command center for the entire business.
- [Model Pool](https://greyfieldstrata.com/platform/model-pool/): Ready-to-use models, organized by topic, use and industry. Standardized, documented and validated, adjusted to your industry and put into production inside your organization.

## Services

- [Consulting](https://greyfieldstrata.com/services/consulting/): Legal, regulatory, risk and technology judgment for decisions that run through the whole organization: from licences to operate to implementing a new rule or validating a model.
- [Development](https://greyfieldstrata.com/services/development/): If you are starting out, we build your platform from the first line. If you already operate, we integrate with what you have and build what is missing. Either way, from the idea to production and inside your organization.

## Blog

- [Four controls that make a deployment defensible](https://greyfieldstrata.com/resources/blog/four-controls-that-make-a-deployment-defensible/): Branch policy, independent review, automated checks and an audit trail. None of them slow a team down as much as an unexplained production change does.
- [Three layers that run through every organization](https://greyfieldstrata.com/resources/blog/three-layers-that-run-through-every-organization/): Technology, the legal framework and models are not departments: they are layers that cut across every department. Almost every important problem touches all three at once.
- [Why a normal distribution understates your VaR](https://greyfieldstrata.com/resources/blog/why-normal-tails-understate-your-var/): A 99% VaR computed under normality and under a Student-t with four degrees of freedom can differ by more than a percentage point of the portfolio. That gap is a policy decision, not a detail.

## Research

- [Explained compute: the result and what drove it](https://greyfieldstrata.com/resources/research/explained-compute/): Calculating a return is not hard. The value lies in knowing what drove it. A note on why a calculation should also deliver its explanation.
