Cofactor, by ChangTech

Private launch list

Digital employees, scoped before they ship.

Built for UK teams who can’t ship AI agents without audit, identity, and a kill switch. First-wave allocation, founding-tier pricing, and the audit dossier land with launch-list subscribers. The full service opens when the list does.

A forthcoming service, with the audit story told first.

Cofactor ships AI agents scoped to a defined job description — bounded by engagement rules, kill-switched, and handed back to a named human owner. Launch-list members receive the audit dossier, the bench table, and the founding-tier pricing before the public release. General availability opens when the list does.

Why Cofactor

This is not another AI agent vendor.

Most agent builds die in audit. Cofactor is scoped, kill-switched, and audit-ready from day one.

Most agent builds die in audit.

DIY agents hit walls on identity. Off-the-shelf SaaS is over-fit on workflow, under-fit on audit. Hiring AI engineers is slow and risky.

Cofactor is scoped. Kill-switched. Audit-ready.

Identity, policy, action log, fallback rules — built in. Bounded by an explicit engagement scope: target, rate, kill switch.

Launch-list members see the audit story first.

The audit dossier, the bench table, and the founding-tier pricing land with subscribers before public release.

Why join the waitlist

What you get by joining early.

First-wave tier allocation

Subscribers get priority access to Starter, Growth, and Scale launch slots before they open to the public.

Audit dossier preview

The full audit story — engagement rules, compensating controls, kill-switch behaviour — lands with the launch list first.

Direct line to the founding team

During onboarding, launch-list members work directly with the founding engineers — no account-manager handoff.

Anchor pricing locked

First-wave rates are held for the launch cohort. Renewal terms published with the service; no post-launch reprice.

Principles

What Cofactor stands for.

Bounded scope

A Cofactor is scoped to one workflow with a defined SLA — never general-purpose. The scope document is signed before deploy.

Audit-grade by default

Identity, policy, action log, and compensating controls are built in. Audit-ready day one, not as a post-engagement retrofit.

Handback, not silent failure

Every Cofactor is designed to hand back to a named human owner. Kill switch and fallback path are part of the engagement, not a feature add-on.

The problem

Hire-vs-buy is broken at the AI-headcount level.

Off-the-shelf SaaS is over-fit to one workflow, under-fit on audit. DIY agents hit walls on identity. Hiring AI engineers is slow and risky. Meanwhile the 2026 productivity gap is visible at the board level — CFOs are asking why AI hasn’t moved the needle, and the honest answer is “we have, but unevenly, without audit.”

Our way

Three phases. Audit-grade output.

  1. 01

    Audit

    Identify candidate workflows. Score each on volume, complexity, audit-trail depth, regulatory exposure. Output: ranked 3-Cofactor roadmap with total cost / benefit.

  2. 02

    Scope

    Job description for each Cofactor. Engagement rules: target, scope, rate, kill switch. Compensating controls and human fallback path. Output: signed scope document and test plan.

  3. 03

    Deploy

    Build, train and test in a sandbox. Live deploy under engagement rules. 90-day feedback loop and KPI dashboards. Output: a working Cofactor and a monthly operations report.
