BRSR filing, without the annual scramble.
Chaperone holds your ESG evidence through the year and flags what is missing while it can still be retrieved. BRSR Close then drafts the disclosure across all nine principles, with your team approving every figure. One representative, in conversation, completes the filing. The system carries the format, the arithmetic and the trail. The last-quarter scramble becomes review and sign-off.

One system carries the filing, from first bill to final disclosure.
Chaperone collects and checks the evidence as the year runs. BRSR Close drafts the disclosure from what it holds. By the time the filing window opens, most of the disclosure is already drafted.
This is the year the assurance glide path reaches everyone in scope.
Most of a filing is assembly.
A BRSR filing is a judgement exercise, and most of its hours go to collection: gathering records, chasing what did not arrive, reconciling what did. The parts that need expertise get whatever time is left. Holding the evidence through the year moves that balance.
Illustrative of where effort concentrates in a BRSR filing, drawn from how the work is commonly described. Proportions are not a measured benchmark and will differ by footprint and scope.
And it compounds. Provenance is produced as each figure is made, which is what reasonable assurance tests. The profile, the bases and the approvals then carry into every later cycle, so the work reduces year on year.

Chaperone reads documents where they arrive, places each record against the site and period it belongs to, and knows what has not come in. It runs continuously, all year.
Scope. Chaperone works the document-heavy sections, where Principle 6 carries most of a filing's load. Narrative and policy disclosures are answered directly in conversation.
The disclosure, drafted in conversation.
BRSR Close works through all nine principles with your nominated representative, drafting from the evidence Chaperone already holds and asking only for what the documents cannot answer.
Who holds the pen. The system carries the template, the conversions and the cross-references. Your representative carries the judgement, and the filing remains the company's.
How a figure gets made.
From a demonstration session: a site with no water meter, and a figure that cannot be read off a bill.
- Are bathing or shower facilities available for the engineers?
- Is the water used only for domestic purposes such as drinking, sanitation and cleaning, or also in industrial processes, cooling or manufacturing?
- Do you have meter readings or tanker supply logs, or shall I proceed on benchmark data under IS 1172:1993 (Reaffirmed 2021), Code of basic requirements for water supply, drainage and sanitation?
→ 4 factories × 45 engineers = 180 people
→ 8.1 kilolitres per day
→ approximately 2,958 kilolitres per year, at full-time operation
I will record this as an estimated domestic water figure, on IS 1172:1993 (Reaffirmed 2021). Can your assurance provider accept an estimated benchmark value for water use in this section?
Returning to energy. Could you confirm whether the Pune office units cover the whole company's electricity use, or whether other sites and operations also consume electricity or fuel that should be added before we finalise the total?
The system qualifies before it calculates, separates domestic from process water, and records the estimate with the standard cited and the assurance position on record.
Reporting platforms organise the work. This system does the work.
The tools most companies use assign owners, issue templates, send reminders and show progress. Someone still reads every bill, decides every unit and basis, and answers to the assurer. Here, the system does that part too, and your team reviews its work.
What an assurer asks. Which standard the water estimate rests on, who accepted it, and why the same basis held across sites. Those answers are recorded here as the figure is made, because they cannot be recovered afterwards.

Worth asking.
We already use a reporting platform. Where does this fit?
Underneath it. A platform is where your teams enter and publish data. It does not read the evidence, and it does not know what has not arrived. This system does the assembly: documents in, register maintained, disclosure drafted, with every figure sourced. If the group keeps its platform for publishing or for other frameworks, the output feeds it. If not, the filing is produced here end to end.
Does our data leave our environment?
No data is retained by Mitochondria. Documents are processed transiently through our cloud infrastructure, encrypted in transit and at rest, and the output is returned to your nominated workspace. Mitochondria is ISO 27001:2022 certified, and the connection model and data handling terms are set out in our DPA, aligned with the GDPR, UK GDPR, and India's DPDP Act. Where a sector requires it, deployment within your own environment is available.
We are already mid-year. Do we have to wait to start?
No. Chaperone can be pointed at what you already hold, which establishes where you stand for the current year and what is missing from it. The continuous model then applies from that point forward. Starting mid-cycle means the first year captures less than a full one, and the gaps it surfaces are still worth knowing before the window opens.
How does this help with BRSR Core assurance?
Reasonable assurance asks for source-traced evidence behind the template. Because every figure is linked to the document or conversation it came from, and because estimates carry the standard applied and the approval given, the trail an assurer asks for is produced as the work happens, not reconstructed at the end. Where the same basis is used across sites and periods, that consistency is on the record too.
What about sections that no document can answer?
Much of the BRSR, including board composition, policies, stakeholder engagement, and ethics disclosures, is answered in conversation. The system asks your representative directly, explains what each field requires, and records the response against the field. Documents are one input path among several.
How does estimation work where there is no meter?
The judgement stays with you and your assurance provider; the system moves it earlier in the year and puts it on the record. It asks what it needs in order to choose the right basis, states the standard it is applying, shows the calculation, labels the result as an estimate, and asks whether your assurance provider accepts an estimated value for that field. The assumption and the approval are recorded alongside the figure, and the same basis carries into later cycles.
How does the SEBI taxonomy alignment work?
The output is aligned to the SEBI BRSR taxonomy used by the exchange submission utility. Final validation against the current taxonomy happens through the exchange's own utility. Where SEBI amends the schema, the field mapping is updated to follow it.
How well does the system understand the disclosure itself?
It was built in consultation with, and validated by, a leading ESG and climate-reporting advisory, part of an established audit and advisory firm that provides BRSR assurance to listed companies. Its leadership reviewed the working demonstrations and approved both the approach and the output. The disclosure expertise and the engineering sit in the same build, which is why the system asks the questions an assurance review would.
How does this work with our assurance provider?
Every value is traceable to a specific document, a recorded conversation, or a calculated field with its inputs visible. Your assurance provider reviews the same artefact your team does, with no parallel workflow to reconcile.
What happens next year, and what if we leave?
The prior year's context carries forward, so the following cycle opens with what has changed. Your completed filings and your evidence estate are exportable at any point. If you do not return, you keep everything.
What does it cost?
A single listed entity is priced per filing, annually. An advisory practice running filings for several clients moves to an annual practice licence. The range depends on operational footprint and document volume, and is discussed during the walkthrough.
Compliance beyond the filing.
The rest of the compliance estate
Licences, consents and certifications turn on validity dates. Chaperone holds them alongside ESG records and raises expiries early.
