Replace estimates with receipts.

$5B a year. What SMEs collectively spend producing non-defensible carbon estimates for the enterprise customers above them. torch0 turns that spend into a signed receipt the buyer’s auditor can verify.

Infrastructure on top of the standards already being written — ESRS E1, IFRS S2, ISO 14067, GHG Protocol, PACT. Not in competition with them.

What you hand the buyer.

torch0 sits on the supplier side of the procurement table. It produces one signed carbon receipt per product, process, or service unit you sell — methodology published, signature traceable, inputs scored for confidence. Your enterprise buyer drops it straight into their Scope 3 line.

What torch0 is not
  • Not Watershed or Persefoni. Those sell to the enterprise and push questionnaires down to you
  • Not a competing standard. We sit on top of CSRD, IFRS S2, ISO 14067, GHG Protocol, and PACT
  • Not an estimate or industry average. Every number traces to the process that produced it
  • Not a months-long LCA consultancy engagement at €10k–€30k a product
What torch0 is
  • A lightweight, supplier-side instrument that emits one receipt per product, process, or service unit you ship
  • Built from physical reality — process runtime, location, grid intensity at the moment, equipment amortisation
  • Confidence-scored — auditors and procurement teams see where the number rests on measured ground truth and where it leans on modelled inputs
  • Signed and verifiable on the buyer’s side, without taking our word for it

The receipt, the map, and the standards underneath. A signed carbon receipt for every product, process, or service unit you ship. A structured map underneath that makes the receipt defensible. Aligned to the standards already in force.

    Signed, traceable, audit-ready.

    Every unit you ship produces one receipt, signed so it cannot be altered. Each receipt traces to the process that ran, the location it ran in, the grid intensity at that moment, and the equipment amortised across the work. A confidence score per input tells the buyer where the number rests on measured ground truth and where it leans on modelled defaults.

    Measure the machine, not the invoice.

    Underneath each receipt sits a structured map of the process that ran, the location it ran in, the grid intensity at that moment, and the equipment amortised across the work. Numbers built from physical reality, not from procurement spend multiplied by an industry average.

    Infrastructure on top of existing standards.

    We are not writing the standards. The standards already exist and are being released through 2026. torch0 is the system that takes whatever framework regulators and standards bodies put out and makes it operationally trivial for a company to produce numbers that comply.

Sell defensibility, not absolute accuracy.

In Scope 3, absolute truth doesn’t currently exist — two reputable methodologies recently produced figures 72% apart for the same organisation, same year. What an auditor at the buyer’s end actually needs is a number they can defend. torch0 underwrites that with three things: methodology published openly so it can be verified independently, numbers built from physical reality instead of spend multipliers, and a confidence score on every input so the buyer sees exactly which parts of the calculation are measured and which are modelled.

$100k to $1m ARR per enterprise contract on the line. The supplier with a defensible receipt closes it. The one with estimates doesn’t.

Roughly 10,000 enterprises are now in scope for Scope 3, each with around 150 material suppliers — about 500,000 SMEs under procurement pressure to hand over credible carbon data. Today that is a competitive advantage at procurement. Once the infrastructure matures and the next regulatory tightening lands, it becomes the price of doing business.

From machine to receipt in three steps. Instrument once, receipts flow with every unit you ship.

  1. 01

    We instrument the machine.

    A short engagement with your operations team to identify the process, product, or service unit that needs a receipt. Process runtime, location, grid intensity at that moment, equipment amortisation — the physical inputs go in.

  2. 02

    Receipts start flowing.

    Each unit shipped produces one signed receipt: process, location, grid, equipment, carbon, confidence score per input. Stored under your account. Queryable, exportable, signed so it cannot be altered.

  3. 03

    You hand the buyer the receipt.

    The enterprise customer drops it straight into their Scope 3 line. Their auditor verifies the math against the openly-published methodology, without taking your word for it. You close the contract. The buyer closes their disclosure.

Who torch0 is for.

We are taking on a small number of design partners. We work best with suppliers where a CSRD-bound, SB 253-bound, or IFRS S2-bound enterprise customer is asking for credible Scope 3 numbers, where the contract on the line is material, and where someone internal owns the answer.
