Hi, I am Lisa. Running one company is complicated enough. Managing an entire group of companies, across different countries, is another story.

Ownership records, directors, legal documents, filing deadlines, board resolutions. Too often, everything is spread across spreadsheets, shared folders, and emails.

And finding the right information takes far longer than it should.

At yellow3 Lab, we've built Entity & Governance OS to bring everything together.

One intelligent workspace where you can manage every company in your group, understand who owns what, keep track of legal obligations, and maintain a complete record of important decisions.

Whether you're managing your own holding companies or looking after multiple clients as a law firm, everything is organised in one place.

You can see your entire company structure, including the people behind each business. You can track upcoming deadlines, manage corporate documents, and prepare resolutions for approval and signature.

But here's where it gets interesting.

Your own AI company secretary is built right in.

Ask a question about your companies, their ownership, or their governance, and get an answer based on your actual company records, with references to the documents behind it.

Need a board resolution or written consent? Your AI company secretary can prepare the draft using information already on file, ready for your review and approval.

It can even help prepare filing packs for upcoming deadlines, identifying what information is available and what still needs attention.

And importantly, when information is missing, it tells you rather than making something up.

No searching through endless folders. No starting from scratch every time.

Entity & Governance OS is more than a place to store documents.

It's a smarter way to manage corporate governance, with your companies, compliance, documents, and built-in intelligence working together.

Entity & Governance OS, from yellow3 Lab.

Every company in order, and the paper trail to prove it.

Hi, I'm Pietro. Businesses don't need more software to manage. They need better ways to get things done.

At yellow3 Lab, we believe the future of software is about outcomes. Not asking people to spend their time learning another platform, managing technology, or figuring out how to make systems work together.

That's our responsibility.

When you choose a platform from yellow3 Lab, you get a complete, AI-powered business solution.

We take care of the hosting, maintenance, updates, and the technology behind it.

You focus on your business.

But we also know that no business stands still.

Your organisation grows. Regulations change. New opportunities appear. And the way you work today may not be the way you need to work tomorrow.

Your platform should evolve with you.

That's why we offer an optional service called Outcome Operator.

Instead of asking you to figure out how to change your software, you simply tell us what you want to accomplish.

Perhaps you want to eliminate a manual process, introduce a new service, or make your team more efficient.

Tell us what you want to improve. We help you define the outcome.

We agree on the scope, the price, and the delivery date, and take responsibility for getting it done.

Our AI-powered technology helps us build and adapt platforms, but you don't need to understand any of that.

Before any change goes live, you review and approve the result.

Your subscription covers your managed platform, including hosting, maintenance, and updates. Business-specific changes are handled separately through our optional service.

We believe this is where business software is heading.

Less time operating systems. Less complexity. More attention on the work that actually matters.

Because technology should serve your business, not the other way around.

You run your business. We run your software and platforms.

Discover how yellow3 Lab's managed AI platforms and optional Outcome Operator service can work for your business.

Why we built it

Governance should not depend on scattered files and someone’s memory.

Company information lives across spreadsheets, shared drives and inboxes. Structure charts go stale. Deadlines slip. Finding who can sign, or answering a simple ownership question, means searching through folders.

We built Entity & Governance OS to connect the companies, the work and the evidence in one workspace, so the next person can find the answer and see the record behind it.

Who it is for

Your own group.
Or the groups you look after.

For owners of multi-company groups

Holding groups, founder and family holdcos, and free zone groups. Bring the companies and their governance work out of scattered spreadsheets and folders.

For firms managing client groups

Corporate paralegals, company secretaries and partners responsible for company administration. Everyone authorised to use a platform can view its records. Separate confidential client records require separate customer platforms.

The complete workspace

From the company register
to the signed decision.

01 / ENTITIES

Know every company.

Keep legal form, jurisdiction, registration number, registered agent, officers and directors in a clean entity register.

02 / OWNERSHIP

Follow every layer.

Turn ownership records into a live structure chart. Calculate beneficial ownership through the layers and flag holdings for review against applicable local thresholds.

03 / FILINGS

See what is due.

Track filings and deadlines across jurisdictions, review overdue and upcoming work, and prepare the filing pack.

04 / RECORDS

Keep the history.

Maintain the minute book and document vault, with versions and executed copies.

05 / APPROVALS

Follow the decision.

Move resolutions through approval and signing, with a timestamped trail of who signed and when.

06 / COMPANY SECRETARY

Ask. Check. Prepare.

Ask questions in plain language. Receive answers from your own records, with a citation for every fact. Draft resolutions or consents using the appointments and ownership on file.

AI built into the platform

A company secretary built in.
Grounded in your records.

Ask questions, prepare documents and get ready for filings inside the same workspace. The company secretary works from the records you hold, with sources you can inspect.

01 / ANSWER

Ask a question. Open the source.

Ask in plain language. The secretary answers only from your own records, with a numbered citation for every factual claim so you can open the exact source. If it cannot find the information, it tells you.

02 / DRAFT

Prepare the document for review.

Describe what you want to approve. Draft a written consent, board resolution, minutes, officer’s certificate or power of attorney using the appointments, ownership and governing documents on file.

Jurisdiction-specific drafting supports professional review before the document is sent for signature.

03 / PREPARE

Get the filing pack together.

Prepare for an upcoming deadline with a checklist, information already held pre-filled, items to confirm with the client and a short cover note to the signatory.

The answer comes with its evidence.

Answers stay within your records. Citations let you check the facts. Missing information is made explicit, so your team can see what still needs to be established.

Your team reviews drafts and makes decisions. The platform supports records and workflows; it does not guarantee legal compliance or replace professional advice.

Know what you are buying

The practical questions,
answered clearly.

Who is it for, and what is included?

Entity & Governance OS is designed for holding companies, family offices, corporate groups, and legal professionals responsible for company administration.

It brings company records, ownership structures, directors, compliance deadlines, corporate documents, and governance activities into one workspace.

Each customer receives their own platform, managed by yellow3 Lab.

Does it come with AI built in?

Yes. Entity & Governance OS includes an AI company secretary.

Ask questions about your companies, their ownership, or governance records and receive answers supported by references to the information held in your platform.

The AI company secretary can also help prepare board resolutions, written consents, minutes, and other corporate documents using the company information available.

Documents are prepared for your review, not automatically approved or treated as legal advice.

What does it cost?

Entity & Governance OS is offered as a managed business platform.

We are finalising the commercial plans, including subscription options and additional services.

You can explore the working example to understand what the platform offers before making a commitment.

How do our existing records get into the platform?

You can add your company information directly through the platform's forms.

This includes company registration details, ownership information, directors, governance records, and relevant documents.

Records are entered individually, giving you the opportunity to check their accuracy as your company register is established.

Bulk spreadsheet importing is not currently available.

How are access and company data handled?

Each customer receives a separate published platform. Company records are kept separate from those belonging to other customer platforms.

Access requires signing in, and your platform can be restricted to invited users.

Administrators can control who may make changes to designated records.

Everyone authorised to use the same platform can view its records, so it is intended for information that can be shared among those users.

The platform is not currently designed for different clients to access separate confidential records inside the same workspace.

Does it replace legal or professional advice?

No.

Entity & Governance OS helps organise corporate information, manage governance activities, and prepare documents.

Its AI company secretary works with the information available in the platform, but it does not replace qualified legal, accounting, or regulatory advice.

Documents and decisions should be reviewed by the appropriate people before use.

Do we need technical knowledge to use the platform?

No technical expertise is required.

yellow3 Lab takes care of operating the platform and managing the underlying technology.

You can concentrate on your companies, their records, and the decisions that matter to your business.

You do not need to manage servers, write code, or become a software developer.

What happens when our business changes?

Your platform can evolve with your business.

You can maintain your company records as directors, owners, and corporate structures change.

If you need additional functionality or changes to how the platform works, yellow3 Lab can help define and deliver an agreed solution through its optional Outcome Operator service.

What is the Outcome Operator service?

Outcome Operator is our optional service for businesses that want yellow3 Lab to take responsibility for adapting their platform.

Tell us what you want to improve. We help you define the outcome.

We agree on the work, the fixed price, and the delivery timing before starting.

Before any change goes live, you review and approve the result.

You focus on the business outcome. We handle the technology.
