STRATAESG

Proof based sustainability platform

The system where sustainability data lives.

Your client, your bank and your auditor no longer want a declaration, they want evidence. STRATA ESG keeps every figure attached to its supporting document, its version and its calculation method, and returns it in the format each one requires.

  • The calculation is reproducible
  • Every figure traces back to its document
  • Your data is never reused

No claim without evidence.

In short

What is STRATA ESG?

STRATA ESG is the French publisher of a sustainability software ecosystem for European SMEs and mid caps. Data is entered once, with its document and its method, then returned in the grammar of nine frameworks. ESG Optimizer is its cockpit.

The frameworks fed by the same dataset

  • CSRD and ESRSESRS E1-6
  • Voluntary standardB3
  • EU Taxonomyturnover capex opex
  • GRI302-1
  • ISSBIFRS S2, §29(a)
  • CDP7.30
  • SASB130a.1
  • BEGESitem 6
  • EcoVadispreparation

What can be checked

Four properties, all of them verifiable.

These are properties of the product, not traction figures.

  • 9 frameworks

    served by a single entry: CSRD and ESRS, the voluntary reporting standard, EU Taxonomy, GRI, ISSB, CDP, SASB, emissions reporting and EcoVadis preparation.

  • 90 seconds

    to know what applies to you, with no account and no card. Eight questions, six regulatory regimes, each dated and sourced.

  • Every figure

    published carries its document, its version and its method. That is what separates data from a declaration.

  • To the decimal

    the calculation can be replayed two years later. Same data, same result, with the method then in force.

What changed

Producing a report became easy. Defending it did not.

Three moves in eighteen months shifted the value from the report to the evidence.

These are not trends, they are legal texts, each with its date of entry into force.

Since 2026

The report became free.

The French state now offers sustainability reporting at no cost, across ten regulations, and more than thirty thousand companies use it. Good. That is no longer where your risk sits.

2 July 2026

The score became a regulated object.

The European regulation on ESG rating providers requires methodologies to be published and encourages separate E, S and G ratings rather than one aggregate score. The regulator has ruled: what matters is being able to show how the figure was obtained.

3 July 2026

What they ask you for is the document.

Your client wants to know where the figure comes from. Your bank wants a reliability level field by field. Your auditor wants the state of your file at the closing date, not today's. No report answers that. A body of evidence does.

Sources: regulation (EU) 2024/3005, the delegated regulation of 3 July 2026 carrying the voluntary reporting standard, and the French public portal.

Our conviction

Sustainability shouldn't be a privilege of size.

Since the Omnibus reform, the sustainability reporting directive only targets large companies, yet the pressure on SMEs hasn't eased: clients, banks and investors all demand sustainability data, now structured by the voluntary reporting standard.

Most SMEs have neither a consultancy's budget nor a dedicated department's time. STRATA ESG closes that gap: a software layer that turns weeks of expert work into minutes, without sacrificing rigour.

The demonstration

One figure, and everything holding it up.

Most software shows you a score.

This is the opposite: a single value, and everything that lets you defend it the day someone asks where it comes from.

What this same value feeds

It is entered once. Each framework reads it in its own place, under its own code, with no re entry and no risk of two reports contradicting each other.

ISSBIFRS S2, §29(a)
Emissions reportitem 1

Illustrative values on a demonstration file. What the capture demonstrates is not the figure, it is the structure holding it up: that structure is identical on a real file.

Versioned, never overwritten

Every correction adds a dated, justified version to the log. On a closed reporting year, reason and note become mandatory: the trail an assurance engagement requires.

Comparable over time

Create your reporting years, close them, compare one year to the previous one. Every variance is computed, converted into the right unit and traced back to its evidence.

Anchored in the real world

Sites, buildings, suppliers, internal indicators: the entity registry links every measure to what carries it, and resolves company, VAT or internal identifiers.

Field capture

Evidence is captured where it happens.

A meter reading, a skip, an incident, an audit visit.

What founds a figure sits on a site, often without a network, and rarely in front of a computer. The field application takes the document at the source and moves it into the vault, with its date, its position and its requirement code.

  • EvidenceA photo, an indicator, a note.
  • IncidentWhat happened, when, and where.
  • TaskWhat was done, attested on site.
  • AuditA visit documented item by item.

The application exists and works, but it has not been sold since 7 August 2026. It is on our list of retracted claims, with its condition for return. Retracted claims

  1. Offline firstThe capture is written to the phone before anything else. No network is needed to work, and nothing is lost if the site has none.
  2. Replay without duplicatesSynchronisation restarts on its own when the network returns. Each capture carries its own identifier, so a photo replayed three times only lands once.
  3. Attached, not dumpedThe requirement code is picked from a closed catalogue. A capture that attaches to no requirement is refused, rather than filed in a catch all folder.
  4. Sealed on arrivalThe document enters the vault, takes its fingerprint and joins the graph. From then on it behaves like any other piece of evidence in the file.

The dividing line

A score can be argued with. Evidence can be checked.

Four differences, each verifiable in the product rather than in a brochure.

What the market sells : A completed questionnaire

What we sell : An attached supporting document

Versioned vault and a two way evidence graph: where this value comes from, and what moves if you change it.

What the market sells : An assigned rating

What we sell : A recomputable rating

Point by point breakdown, quantified counterfactual, and a calculation tested to return the same result on the same data.

What the market sells : A label with a date

What we sell : A continuous trail

Hash chained registry, sealed journal, and evidence expiry tracked over time.

What the market sells : A file you send

What we sell : Access that is traced and revocable

You see every read, how long it lasted, and you cut it off whenever you want.

The deliverables

What you send, and what the other side does with it.

A report as an attachment ends up in an inbox.

Our deliverables can be checked by whoever receives them, with no account to create.

  1. Your client's own file, filled in

    You upload the questionnaire you received. It comes back in its original format, in its original cells, formulas and formatting preserved, with an annex proving every answer. The following year, only the values that need updating are asked for again.

  2. Bounded access, not an attachment

    Your banker, your auditor or your client opens a link. They see what you decided, for as long as you decided. You see every read, and you cut it off whenever you want.

  3. An extract, not the whole invoice

    You prove a figure without sending the full document. The extract carries the fingerprint of the source document: the recipient checks that it really comes from there, without seeing the rest.

  4. A sealed file, with its verification code

    Two exports of the same unchanged file carry the same fingerprint, two years apart. That is the difference between a document and a piece of evidence.

The golden rule

Every figure traces back to timestamped evidence

A score you cannot explain will not survive three minutes in front of an auditor or a procurement team.

Every published value keeps the link to the document that grounds it, to the datapoint that carries it and to the framework disclosure that requires it. The path can be walked in both directions.

The evidence chain, both waysThree linked steps, on an anonymised demonstration file: the electricity invoice grounds the ENERGY_TOTAL datapoint, which serves the ESRS E1-5, VSME B3 and GRI 302-1 disclosures. The path can be walked back from the disclosure to the uploaded document.EvidenceElectricity invoiceDatapointENERGY_TOTALDisclosureESRS E1-5VSME B3GRI 302-1what depends on itwhat grounds it

Demonstration file, anonymised

  1. Evidence

    Electricity invoice

    Uploaded, timestamped, fingerprint frozen. A supplier certificate grounds the renewable share in the same way.

  2. Datapoint

    ENERGY_TOTAL

    Total energy consumption, in the data backbone. Every correction adds a dated, justified version: nothing is ever overwritten.

  3. Disclosure

    ESRS E1-5, VSME B3, GRI 302-1

    The same datapoint feeds every framework that asks for it, with no re-entry.

The codes shown are the product's own. No figure is shown here: it would have been measured on no file. On yours, the same path carries your values, your fingerprints and your dates, and the score is then computed from the state of each required disclosure, by a fixed rule.

What makes the difference

Auditable evidence, not just a declarative journey

A completed questionnaire

An attached document

A form states an intention. A dated document, tied to the data it grounds, states a fact that stands up to challenge.

An assigned rating

A recomputable rating

A rating nobody can reproduce will not survive a contradiction. Ours can be replayed and explained, disclosure by disclosure.

A label at a point in time

A continuous trail

A stamp earned once ages. A log of versions and evidence follows the company year after year.

This traceability requirement applies across the whole ecosystem. Our scores remain indicative and do not replace an audit by a licensed statutory auditor: they provide the file such an audit can rely on.

The architecture

One cockpit, modules that plug in.

ESG Optimizer is the cockpit where your data lives.

Scope, Watch and Academy are modules that plug into it, Foundation gives it its baseline. Every building block is shown with its real status, never with a promise.

A second region

Africa, served by the same engine.

Same data foundation, different demand. In West Africa, what is asked of you is not a score, it is a file that holds in front of a lender or a European buyer. The region has its own domain, its own currency and its own price list.

Inside the cockpit

What used to be a separate product is now a native layer.

The EU Taxonomy and the social pillar are not sold separately.

They are built inside the cockpit, on the same data, so clients never re-enter what they have already provided. This is the real state of play, with no promise dressed up as a feature.

Nine frameworks served by the same dataAn energy consumption entered once, with its document, its version and its method, comes out under the code of each of the nine frameworks: ESRS E1-6, basic module B3 of the voluntary standard, turnover, capex and opex denominators of the Taxonomy, GRI 302-1, IFRS S2 paragraph 29(a), CDP 7.30, SASB 130a.1, item 6 of the emissions report and EcoVadis preparation.One datapointentered oncedocument, version, methodCSRD and ESRSESRS E1-6Voluntary standardB3EU Taxonomyturnover capex opexGRI302-1ISSBIFRS S2, §29(a)CDP7.30SASB130a.1Emissions reportitem 6EcoVadispreparation

  • Labels and environmental claims

    Label preparation and claim review, on the same evidence base as the rest of the cockpit.

Your right, before your obligation

A two hundred line questionnaire is not enforceable. The cap has a legal basis.

The Omnibus directive sets a value chain cap: a client cannot require a partner with fewer than one thousand employees to provide more than the content of the voluntary standard, adopted by delegated regulation on 3 July 2026.

The cap takes effect for financial years starting from 2027. Until then, it is invoked in a commercial negotiation as an adopted standard and a known ceiling, not as a prohibition already enforceable before a court.

Indicative diagnostic, produced by applying public rules to your answers. It does not constitute legal advice.

  • The exact limit that applies to you

    Eight questions, six regulatory regimes reviewed, each with its text and its date of entry into force.

  • The sentence you can put to them

    Written, sourced, ready to paste into your answer. This is not a refusal on principle, it is a professional reply.

  • What you still have to produce

    The list of what remains owed, named, with who holds it inside your company and where to look for it.

The calendar

Dates are not intentions. They are legal texts.

Four deadlines already published, with what they carry.

None of them is a projection of ours.

Who it is for

Nobody wakes up wanting sustainability software. Everybody wakes up with an email.

We do not segment by company size, we segment by the scene that triggers the search.

The scene

An email from your largest client's procurement team. Sustainability questionnaire attached, one hundred and eighty lines, in house format, fifteen days to answer, and a sentence about supplier listing.

SME under pressure from its value chain

This is not compliance, it is commercial risk. No time, no data, no idea where to look. And above all the fear of writing something untrue.

What we answer

You do not have to give everything. And what you do give, you must be able to prove.

The solution for this profile

The scene

Your clients ask you the question, you have no tooled method, and you spend your evenings in a spreadsheet.

Accounting firm and sustainability consultant

The real constraint is not the tool, it is the billable method and protecting your professional liability. Signing a sustainability deliverable puts your name on it.

What we answer

Bill the advice, not the data entry. And when you sign, the file holds.

The solution for this profile

The scene

First year under the revised standards, a statutory auditor about to check, and a collection spreadsheet that will not survive it.

Sustainability lead of a company in scope

The file has to survive a verification, not only a reading. Replay at a past date, assurance levels, separation of duties, sealing before publication.

What we answer

Your file has to survive a verification, not only a reading.

The solution for this profile

Our rule, applied to ourselves

What we removed from our pages, and why.

We ask our clients to claim only what they can prove. Here is what that rule cost us.

  • Tamper proof evidence

    Removed on 1 August 2026

    Where : European offer grid

    Our evidence is hash chained, which makes any later modification detectable. It is not anchored with a third party timestamping service: nobody outside certifies that a document existed on a given date. Detectable is not tamper proof, and the gap between the two is exactly what an auditor comes looking for.

    Condition for returnThe day a qualified timestamping provider is active and anchoring actually runs.

  • More than 200 indicators

    Removed on 1 August 2026

    Where : Home page and sales pitch

    The figure came from adding up overlapping lists, the most common way to inflate a counter without quite lying. The real count, taken on 22 August 2026: 136 questions in the voluntary questionnaire, 168 in the CSRD journey, 88 disclosure requirements in the register. None of these numbers is a number of indicators.

    Condition for returnIt will not come back. A count of indicators says nothing about the quality of a file.

  • 90 day action plan

    Removed on 1 August 2026

    Where : Description of the analysis deliverable

    The engine produces indicative deadlines in a closed vocabulary (immediate, short term, medium term). It produces no 90 day horizon, and it would have no deterministic way to do so without knowing your internal constraints.

    Condition for returnThe day the effort and cost of each action are quantified from your file, not from a market average.

  • Guaranteed SLA

    Removed on 1 August 2026

    Where : Enterprise offer

    A service level commitment is a contractual object: it requires a quantified rate, a measurement window, and a penalty if the rate is missed. None of our contracts carried one. Availability is measured and published, which is something else and is said differently.

    Condition for returnThe day a contract carries a quantified rate and a penalty. Not before, whatever the actual quality of the service.

  • Mobile field application

    Removed on 7 August 2026

    Where : Enterprise offer

    The application exists and works, but it talks to the product through a single entry point and had not changed since mid July. That is not the level of finish an Enterprise offer line commits to. We stopped selling it before taking it back in hand, rather than the other way round.

    Condition for returnThe day it is taken back in hand, or never if we decide not to.

This list is dated and it will grow. It is the only sales argument we actually want to keep.
