How Axion Lab works

01/ 06
  1. 01

    Scoping call with an expert

    We agree who the report is for and what it needs to cover.

  2. 02

    Data intake

    You send the files you already have, as they are.

  3. 03

    AI draft and Q&A

    The AI analyses everything you sent, drafts the full report, and asks you only what your documents could not answer.

  4. 04

    Expert during the work

    While the report is being built, you can pull the expert in: a call, a working session, a second opinion on the draft.

  5. 05

    The final report

    The expert signs the report; you keep it, along with the data and the model behind the numbers.

  6. 06

    Expert after delivery

    After delivery, the expert can respond to additional questions.

FAQ

A finished sustainability report built for the decision its reader needs to make.

That can be buy-side due diligence, a post-acquisition plan, an annual portfolio review, a lender submission, a board recommendation, a carbon footprint and decarbonisation pathway, or a vendor due diligence. The format changes with the audience, but the output is always a completed document rather than a dashboard for your team to operate.

We work with private equity funds and their portfolio companies.

The same analysis may need to serve several readers: the deal team, investment committee, board, lender, LP, customer, or regulator. We agree who the report is for at the start and write it for that reader.

A named senior sustainability expert scopes the work, chooses the method, reviews the analysis, owns the conclusions, and signs the final report.

The signature is not an audit or independent assurance opinion. If you need either, you appoint a third party. We prepare the work so that the reviewer can trace the figures, sources, and assumptions.

The AI reads the files, extracts the data, runs the calculations, benchmarks the results, drafts the report, and identifies what the documents did not answer.

The expert sets the scope, makes the judgement calls, checks the analysis, interprets the result, and signs the work. You can speak to the expert during the project and after delivery.

With each engagement, we improve the reusable methods, templates, and review checks. We do not retain client files or use client data to train models.

First, we agree who the report is for and what it needs to cover. You then send the files you already have, as they are.

The AI builds the first draft and asks only for information the documents could not provide. The expert reviews the work with you, signs the final report, and remains available for questions after delivery.

The documents you already have. On a deal, that is usually the data room. For a portfolio company, it may include previous reports, policies, operational data, invoices, or board materials.

You do not need to complete a long questionnaire before we begin. We ask targeted questions only where the documents leave a material gap.

We use the best available source and show where the evidence ends. If a figure must be estimated, the report labels it as an estimate and states the basis used.

Every material number links to a source or a written assumption. Missing data remains visible rather than being hidden inside the model.

Yes. We can work across several companies, sites, or legal entities and give the fund a consistent portfolio view.

We agree the common scope, definitions, and output format first. Each company still keeps its own evidence, calculations, and assumptions, so portfolio consistency does not erase company-level differences.

Your sustainability lead keeps the company context, management relationships, priorities, and final say. We take on the production work: reading the files, building the analysis, benchmarking performance, and drafting the report.

This gives the internal team more time for decisions and implementation without handing those decisions to an outside firm.

Software can help collect and organise data. But someone on your team still has to set the scope, resolve gaps, interpret the result, write the report, and answer when a board or lender questions it.

We deliver the finished, expert-signed document. There is no new system for your team to learn or operate.

A consultancy can produce similar work. The difference is how the work is built.

We use AI for the repeatable production work and senior experts for the decisions that need judgement. That reduces the hours spent extracting data, rebuilding models, and drafting standard sections, which is why we can charge less than a traditional advisory team.

We agree the relevant standard or reporting framework when we scope the deliverable. The report then states which framework it uses, where the data came from, and which assumptions were required.

Our role is preparation and review. Where a standard requires an audit, assurance opinion, or independent verification, that conclusion must come from an appointed third party.

We show the source, calculation, and assumption behind the figure. The expert who signed the report answers the questions and explains the judgement used.

We cannot promise that a third party will accept every conclusion. We can make the work traceable and stand behind how it was prepared. In one lender case, our work cleared a submission that had been stalled for 18 months.

You do. You keep the final report, the supporting data, and the calculation model behind the numbers.

The work does not depend on an Axion Lab subscription or a platform login. You can use it after the engagement ends and pass it to your own advisers or reviewers.

We operate in the European Union and comply with the General Data Protection Regulation and the EU AI Act. Client data is kept separate between engagements, is not used to train models, and is not retained after delivery.

We can agree any deal-specific access, deletion, or confidentiality requirements before the files are shared.

We start with a call about the company, the decision, and who will read the work. Then you send the documents you already have.

You can begin with one company and one deliverable before deciding whether to use the same approach across the portfolio.
