The building's carbon
before the concrete.

Tangible reads a design and tells you what it's made of - the quantities, the cost, and the carbon baked into every wall - while you can still change the answer.

CAPTION: A logo on a plate, but the real subject is invisible - the tonnes of CO2 locked inside a building before anyone flips a light switch. Tangible's whole job is to make that visible.

The Scene

A spreadsheet nobody wanted to fill out

Somewhere in a preconstruction office, a set of drawings sits on a screen. It looks finished. It is not. Buried inside those lines are thousands of decisions - this concrete, that steel, this much of it - and every one of them carries a number the industry has spent decades ignoring: the carbon it took to make the stuff the building is made of.

For years, calculating that number meant a human, a spreadsheet, and a very long afternoon. Most people skipped it. Tangible's bet is that they shouldn't have to - because a machine can read the drawing faster, and attach the carbon automatically.

What It Is

Software that reads a building

Tangible is a B2B platform for the least glamorous, most important moment in construction: preconstruction, when a design still exists only as models and drawings. Feed it a Revit model or a PDF, and its AI extracts the material quantities - every cubic yard, every tonne - and classifies them by the industry's own standards, MasterFormat and Uniformat.

Then it does the part humans dread. It maps those materials to third-party verified Environmental Product Declarations and calculates embodied and whole-life carbon across the lifecycle stages a specialist cares about - A1 through A5, B, and C.

The result is a single source of truth where quantities, cost, and carbon live on the same screen - and every number traces back to the exact geometry or drawing callout it came from.

Because the data is live, teams can compare design versions across schematic, design-development, and construction-document phases - and watch cost and carbon move together as the building evolves. Change a spec; see the trade-off instantly.

It plugs into Autodesk Construction Cloud, so the data flows into the tools estimators already use, with a tidy export to Excel for the workflows that never quite left the spreadsheet behind.

The pitch is not "save the planet." The pitch is quieter and more persuasive: know what you're building before you build it.

"Although embodied carbon is still novel in the U.S., it's gaining traction rapidly."
- Anneli Tostar, Co-founder & CEO
The Toolkit

Five moving parts, one answer

01 / Extract

AI Takeoffs

Pulls material quantities straight from Revit models and PDF drawings, classified by MasterFormat and Uniformat, each linked back to its source geometry.

02 / Measure

Embodied Carbon

Maps materials to verified EPDs and computes embodied and whole-life carbon across A1-A5, B, and C stages.

03 / Compare

Design Comparison

See how cost and carbon shift across SD, DD, and CD phases - and find where to cut both.

04 / Report

Portfolio Reporting

Benchmark carbon across an entire portfolio for sustainability reporting and regulatory compliance.

05 / Connect

Autodesk Integration

Feeds materials data into Autodesk Construction Cloud and out to Excel, fitting existing estimating workflows.

The point

Cost + Carbon

The whole thesis: greener and cheaper aren't enemies. Put them on one screen and let the design team decide.

The Founders

Two classmates, one frustration

AT

Anneli Tostar

Co-founder & CEO

Before Tangible, Anneli launched the US operations of a real estate sustainability consultancy. She frames the long game bluntly: a full-stack platform where teams eventually track projects, study case studies, and order materials.

NG

Nicole Granath

Co-founder & COO

Nicole came from inside the supply chain, as a sustainability manager at a flooring manufacturer. She knows where the carbon hides because she used to be the one accounting for it.

They first met as undergraduates at Harvard. Years later, the same problem kept surfacing from opposite ends of the building industry - developers wanted lower-carbon materials, but had no reliable way to find, price, or prove them. Tangible is the map they wished existed.

Who Uses It

Builders who stopped guessing

Tangible sells into real estate developers, general contractors, and the preconstruction teams who live in estimating spreadsheets. These aren't companies that adopt software for the novelty - they adopt it when guessing their numbers stops being acceptable.

Field Notes

Four things worth knowing

Back to the Scene

The drawing, revisited

Return to that preconstruction office. The same drawings, the same screen. Only now the invisible is visible: next to every line sits a quantity, a cost, and a carbon figure that traces back to the geometry it came from. The long afternoon with the spreadsheet is gone. The decision arrives with the number already attached.

That's the small, stubborn thing Tangible changed. Not the building - the moment before it. And in an industry responsible for a tenth of the world's emissions, the moment before is exactly where the leverage lives.
