Your AI colleague for sustainability reporting

The problem

Sound familiar?

• “Our customers want our carbon footprint, and right now it lives in a spreadsheet that nobody fully trusts.”
• “We owe a sustainability report every year, and every year it gets rebuilt from scratch out of last year’s PDF.”
• “We set targets two years ago. Today nobody can say cleanly where we actually stand against them.”
• “Half our footprint sits in our supply chain, and chasing suppliers for value-chain data is a job none of us has the hours for.”
• “Every quarter it’s another questionnaire or rating. EcoVadis, CDP, a customer survey, all asking the same things in different formats.”
• “Numbers go out under deadline, and if an auditor or a journalist pushes back, I’m the one who has to defend every figure.”
• “We looked at hiring; too slow and too expensive. Consultants quoted enterprise prices and left us nothing to reuse. The software we tried just handed us a blank form to fill in ourselves.”

The cost reality

The real cost of doing it yourself

A single sustainability deliverable, a carbon footprint, an annual report, or an external rating like EcoVadis, can swallow 50 to 500+ internal hours. The tools and subscriptions you bought are less than 10% of the real cost. The rest is your team’s time, the time you don’t have.

What we do

What we can take off your plate

It starts with one data foundation. The same company data, your spend, utilities, prior reports and supplier inputs, feeds every output below. Bring it in once, reuse it across every reporting need. Whatever your customers, your board, or the regulator asks for, our AI drafts it from that data and a senior ESG expert signs off.

• External questionnaires and ratings. EcoVadis, CDP, customer surveys and the rest, answered once from your evidence base and reused across every format.
• Supplier and value-chain data (Scope 3). Collecting and estimating the emissions that sit outside your own walls, drafted from the data you hold and the inputs we gather from your suppliers, so the largest part of most footprints stops being a blank.
• Goal and target tracking. A clear, current view of where you stand against the sustainability targets you set, updated as your data changes.
• Internal sustainability reports. Built from your prior years of data plus this year’s updates, drafted in your format and ready to review, instead of rebuilt from a blank page every year.
• Carbon and CO2 footprints. Your annual emissions done properly, including spend-based estimates where you do not yet have primary data. Numbers you can stand behind, not a spreadsheet nobody trusts.

Gather your data once, then use it to answer everything the market asks of you.

What you get

What you actually get

Three outcomes, described by what lands on your desk, not how it’s built.

• The finished deliverable, not a tool. We return the completed carbon footprint, the drafted report, or the filled-in rating response: evidenced and ready to use. Not a dashboard. Not a blank form.
• A senior ESG expert’s name on it. Every figure is reviewed and signed off by a senior sustainability specialist before it reaches you.
• It gets easier every time. We build a private file of your company’s data, documents and prior work. The first job is the heavy lift; after that we already hold your data, so each cycle asks less of you and starts from what we know, not a blank page.

Build your sustainability data once. We reuse it across footprints, reports, targets, supplier data and the questionnaires your customers send, so you’re not re-entering the same numbers in ten formats.

The bigger picture

Where this is going

Today we do the reporting for you: footprints, reports, target tracking and questionnaires, each one signed by a senior expert. That is the start, not the whole plan. Every job we run builds a private, reusable record of your company and sharpens the engine behind it, so each cycle gets faster and cheaper. We are building Europe’s AI platform for in-house sustainability teams, the place your team turns to for carbon accounting, reporting, CSRD, supplier due diligence, ratings, and whatever the next regulation asks for. The service is how we earn that, one deliverable at a time.

Founding customers

The beta

We are live and taking on a small group of founding customers now. Not a waitlist, not a demo. Beta means you work directly with the people building Humboldt while the platform is still taking shape.

What founding customers get:

• Direct access to the team. You talk to the founders and the ESG specialists doing your work, not a support queue.
• A say in the roadmap. What we build next is shaped by the work and problems you bring us.
• Founding terms. Early pricing and terms that we honor as we grow.

What we ask in return: real work with real deadlines, and honest feedback on what works and what does not. That is how we get genuinely good at this before we go wide.

Who it's for

Who it’s for

We work with in-house sustainability and ESG leads at European mid-market companies, across construction, manufacturing, food, retail, services and more.

This is for you if:

• You carry sustainability for a company that is big enough that the work is constant, too small to staff a full sustainability team.
• The work currently lands on a sustainability lead, or a Quality, Compliance or Operations person who never signed up to be the whole sustainability department.
• Customers, your board, or new regulation keep asking for numbers, reports and ratings faster than you can produce them.

If a request is sitting in your inbox right now, a carbon footprint, a report, or a customer questionnaire, that’s exactly the moment to talk to us.

Quality assurance

A senior expert signs every answer

We’re not handing you raw AI output. A senior ESG specialist reviews every figure, checks it against your evidence, and puts their name to it before it goes anywhere. Every number is traced back to a source document, so it holds up when a customer’s procurement team, an auditor, or your own board asks “where did this number come from?”

We never invent a number. If the evidence isn’t there, we ask you for it; we don’t guess.
