About Capstones

We build softwarethat reads thedocuments.

Construction runs on paperwork that nobody has time to read. So we taught software to read it, and to show its work.

A project already holds the answer to most of what it asks.

A commercial project runs on documents. The drawings, the specifications, the submittal log, the eight months of email — the answer to most of what gets asked is somewhere in that record already.

It still takes a median of 9.7 days to answer one RFI, and about one in eight never needed asking at all. Not because the question was hard, but because finding the answer meant somebody reading a spec section they did not have time to read. Navigant Construction Forum, a study of 1,000,000 RFIs across 1,300 projects.

That is not one problem. It is the same problem showing up at four different points in a project — in the model, at the agency, in the estimate and in the field — and each time it goes uncaught, it turns up again later with a bigger number attached.

Capstones builds one tool for each of those four moments.

What we hold to

01

The answer is usually already in the project.
We do not ask a model what it thinks. We make it read the drawings, the specifications and the correspondence the project already has, and cite the document and page it took each answer from. Where the documents do not settle a question, the draft says so rather than inventing an answer.

02

Nothing sends itself.
The software prepares; a person approves. FieldPE drafts straight into Procore so the work is ready when you are, but nothing is issued to an architect, owner or sub, or lands in anybody's inbox, until someone has read it. That gate is not a preference you can switch off — it is the reason the output is safe to use.

03

Your project data stays yours.
It is never used to train models. You can export everything we hold for your company, and you can have it deleted. Both are things the system does on request, not promises in a policy.

04

Narrow and right, over broad and plausible.
Construction software fails when it is confidently wrong about a building. We would rather ship four tools that each do one job against real project documents than one that does everything approximately.

What we're building

01

Draxler
Virtual design & construction — VDC
In development

02

Iris
Permitting
Live today

03

Specflow
Pre-construction
In development

04

FieldPE
Project engineering
Live today

Two of the four are live. Two are not.

FieldPE is in production against real Procore projects, and Iris reviews Florida permit sets before they are submitted. Draxler and Specflow are in development, and until they are finished their pages say exactly that instead of showing a feature list we have not built yet.

Working with us early

Two of the four products are still in development. If one of them is the problem you actually have, tell us — early users shape what ships.
