Enterprise · built with design partners

Calculation infrastructure for teams that have to explain their numbers.

When a number goes to a customer, a regulator or an auditor, “the spreadsheet said so” is not an answer. CalcFleet runs calculations as versioned, tested, source-cited formulas — and can attach a signed certificate to each result. This page is where that becomes an arrangement for your team.

What we build together

The offer — scoped with you, not sold off a shelf.

None of this is a self-service product you can switch on today. These are arrangements we build together with design partners on top of the engine that already runs the public fleet. If a line below matches your problem, we scope it with you before anything is promised.

Private formula registry

Your internal formulas, written and versioned like the public fleet — pure functions, validated inputs, test vectors — visible only to your team.

Managed VCC issuance

Certificates issued under a dedicated issuer identity for your organization: we run key management, rotation and certificate retention for you.

BYOK / KMS integration

Sign certificates with keys you control. We integrate with your KMS so the issuing keys never leave your custody.

Audit workflows

Hand reviewers certificates and formula manifests instead of screenshots. Every result stays re-checkable offline, byte for byte, years later.

Custom API volumes

Rate limits and quotas sized to your pipeline, agreed in plain terms — not a pricing tier you have to reverse-engineer.

White label widgets

The embeddable calculators, restyled and served under your brand and domain.

Dedicated onboarding

Every arrangement above comes with an engineer working directly with your team — from the first call to the first verified calculation in your production pipeline. Early partners shape what gets built next.

Why CalcFleet

Facts you can check, not promises.

Deterministic engine

Every formula is a pure function: same inputs, same outputs, with units and rounding declared. No hidden state, no model in the loop.

2,400+ automated tests

Each formula ships with hand-verifiable test vectors, internal-consistency checks and schema rejection tests.

Versioned formulas, cited sources

Formulas carry explicit versions and every dataset a citation, so you can say exactly which method produced a number.

VCC live in production

Signed, independently verifiable calculation certificates already run on pilot formulas — verifiable by anyone, offline, without trusting this site.
