Voluntary statement · Modern Slavery Act 2015

Modern slavery statement.

Yiontech LTD (trading as YionStack) is below the £36m turnover threshold that mandates a statement under section 54 of the Modern Slavery Act 2015. We publish one anyway — it codifies how we think about supply-chain integrity and answers a question buyers in the public sector and larger SMEs routinely ask.

Last updated: 10 June 2026

1. Our commitment

We have zero tolerance for modern slavery, human trafficking, forced labour and child labour — within our own organisation and in any supply chain we rely on. We expect every party we contract with to share that position. We regard exploitation in any form as a categorical disqualifier from doing business with us.

2. Our organisation and supply chain

YionStack is a UK-based business operating system delivered as software. Our workforce is predominantly knowledge work (engineering, design, support, operations) employed or contracted on UK terms. We do not manufacture physical goods.

Our supply chain consists primarily of:

  • Cloud and infrastructure providers — Google Cloud, Cloudflare, Stripe, AI providers, transactional email vendors. Each is a large, regulated company with its own published modern slavery statements.
  • Professional services — accountants, lawyers, recruiters, regulated UK suppliers.
  • Office goods and travel — minimal at our scale; UK retail and venue suppliers.

We deliberately keep this surface narrow so we can monitor it credibly.

3. How we assess risk

The areas of our supply chain at highest theoretical risk are subcontracted services in other jurisdictions and ad-hoc procurement of physical goods. Our mitigations:

Concentration

We prefer a small number of well-known, regulated suppliers over many small ones we cannot meaningfully diligence.

Direct employment

People doing the actual work — engineering, support, operations — are direct hires or known UK-based contractors. No labour brokers.

Right-to-work checks

Every hire goes through right-to-work documentation in line with Home Office guidance. The same module our customers use does it for us.

Training

All employees and long-term contractors receive on-boarding that covers modern-slavery indicators and how to escalate concerns.

4. Steps we take

  • Supplier vetting. New suppliers are screened for company status and any sanctions / adverse media. Material contracts include compliance and audit rights.
  • Contractual flow-down. Our standard supplier terms require compliance with the Modern Slavery Act 2015 and equivalent legislation in other jurisdictions where the supplier operates.
  • Whistleblowing channel. Anyone — staff, contractor, supplier, member of the public — can email legal@yionstack.co.uk in confidence. We follow up on every report and protect the identity of the person who raised it.
  • Annual review. This statement is reviewed annually, or sooner if our supply chain materially changes, and re-published with an updated date.

5. Effectiveness

We have not identified any instances of modern slavery, human trafficking or forced labour in our organisation or supply chain to date. We measure our effectiveness by (a) the proportion of our supply spend covered by suppliers publishing their own MSA statements, (b) completion rates on internal training, and (c) the absence of substantiated whistleblowing reports.

6. Approval

This statement is published voluntarily on behalf of Yiontech LTD by its board of directors. It applies to the financial year of publication and will be reviewed annually.

Board approval

Approved by the board of directors of Yiontech LTD (Companies House number 16519666) on 10 June 2026. This statement was reviewed and signed off in line with section 54(6) of the Modern Slavery Act 2015.
