The operating system for residential construction.
Stratum turns a build from a loose stream of texts and photos into a structured, verified record. Work is captured in the field, reviewed by the people responsible, and preserved forever.
Construction still runs on texts, memory, and hope.
The most expensive thing ever built for most families is documented worse than a food delivery. The industry pays for it, every year.
Industry studies consistently put direct rework at around 5% of project cost, and most of it traces back to poor documentation and communication.
Superintendents and PMs report double-digit hours weekly spent hunting for photos, texts, and answers that should be one search away.
Footings, rough-ins, waterproofing, structure: the work that matters most is the work that gets covered by drywall and concrete.
Figures are industry-reported patterns, not Stratum marketing math. The point stands either way: what you cannot prove, you end up paying for.
Three moments Stratum wins you money.
The warranty call
A homeowner reports a leak and names your framing. You open the record: the pressure test, approved, timestamped, photographed. The dispute ends with a photo, not a lawyer.
The catch
A stage gate refuses to close because the insulation evidence is missing a bay. The crew fixes it that afternoon. A $150 fix instead of a $15,000 tear-out.
The premium
Your listing carries a verified build record: every layer, every approval. Buyers trust what they can see. Documented homes defend their price.
From photo to permanent record.
Capture in the field
A tradesman opens the task and the camera guides the shots: wide, detail, alignment, spacing. Minimal typing, bilingual, works offline. Every photo files itself to the right project, room, trade, and task.
Feedback and approval
The superintendent reviews the submission, marks it up, and approves or sends it back with notes. Nothing moves forward on memory or a text thread; it moves on reviewed evidence.
Stage gates enforce the standard
GCs define SOPs and stage gates: the work that must be documented, by whom, before a phase can close. Quality stops being hoped for and starts being enforced.
The record compounds
Every approval lands in a permanent, searchable history: by room, trade, date, and system. What lives behind the drywall stays findable years after the walls close.
The record works for you
The same evidence becomes a homeowner timeline, a warranty defense, marketing content for the realtor as the home rises, and a portfolio for every tradesman who did the work.
Every home, built layer by layer.
Stratum structures a build as twelve named layers: the exact sequence the platform ships with, from the first shovel to the last punch item. Keep scrolling and watch a home assemble.
Designed for gloves, glare, and real job sites.
Camera-first screens that a crew actually uses. Here is a look inside.
Scroll the product.
From the guided camera to approvals, history, and active sessions: the screens your crew will live in.
Built layer by layer. Proven at every stage.
Every task walks the same gauntlet.
This is the actual task lifecycle from the platform's database schema. Work only moves forward through review, and a rejection sends it back, never around.
And once a review is recorded, it can never be edited, by anyone. The record always shows who proved what, and when.
One record. Everyone wins.

The busywork, handled
Photos are tagged, captioned, and checked against the SOP automatically. People stay the authority: AI assists, your team approves.
Photos that know where they are
iGuide integration ties floor plans, LiDAR scans, and measurements to your evidence, so every photo is anchored to a real place in the home.
Work that speaks for itself
Approved work builds live portfolios for tradesmen and their companies. GCs discover proven crews; crews carry their record with them.
Standards, enforced
Phases close only when the required proof exists. The standard you set is the standard that ships.
Any detail, in seconds
Search the entire history of a home by room, trade, date, or system. The answer is a photo, not a phone call.
From job site to sales asset
The same record produces realtor-ready content and homeowner stories as the home rises. Document once, use everywhere.
What the platform notices on its own.
Six real flags from Stratum's demo project on Hutson Avenue. The AI raises its hand; a person always makes the call.
Missing pressure-test photo on the shower-valve task in Primary Bath.
New evidence auto-tagged: rough plumbing · primary bath · copper.
Spanish voice note from the field transcribed to English for review.
Rough Plumbing ready for draw: 14 / 14 tasks approved.
Rough HVAC is trending 3 days behind plan.

Advisory by architecture: ADR-0007 makes human approval authoritative. AI assists with tags, captions, and flags. It never approves construction work.
You'll never think about this part. That's the point.
Stratum is real, working software, not a rendering of one. Here is what that means for you, in plain English.
Once work is approved, the record locks. Not by policy: the database itself refuses edits.
Every photo files itself to the right project, room, task, and person. Years later, it's one search away.
Invite-only, role by role. Your crew sees their work; your homeowner sees their home; strangers see nothing.

57,000 lines of TypeScript governed by a canonical data model, 118 implementation specs, and a library of architecture decision records. Five provider adapters are live today; the rest are specified and waiting on contracts, behind the same registry. AI is advisory by design; people approve the work.
Document once. Deliver everywhere.
The platform ships eight export pack types: the same verified record, re-cut for whoever needs it.
Built for every trade.
What is documentation worth to your business?
An illustrative scenario using your numbers, not a promised result. It ignores disputes avoided, premiums earned, and bids won: the upside that is hardest to model and largest in practice.
Serious about the data, because the data is the product.
Evidence is encrypted in transit and at rest on AWS infrastructure, with scoped access per project and role.
Approvals are timestamped and attributed. The record shows who proved what, when. It cannot quietly change later.
The record belongs to the build. Export it, hand it to the homeowner, attach it to the sale. No hostage data.
This is not a concept. It has an address.
Stratum's pilot runs on an actual Altoria build in Nashville, seeded into the platform with its twelve layers, eleven rooms, and a full crew of roles.
Three years, twelve quarters, one discipline.
Stratum runs on a written 12-quarter execution roadmap: prove it on our own homes first, then open it up. This is the actual sequence.
Year one
Lock the category, the entity model, the roles, and the first standards packs.
Projects, invites, tasks, evidence upload, and the approval state machine.
Live pilots on Altoria builds: field capture, PM review, homeowner milestones.
Search by room and system, closeout archive, refined proof schemas.
Year two
Trade owner workspace, stronger homeowner portal, baseline dashboards.
Blueprint intake, vision boards, room and feature packaging.
Realtor packs, lender packets, trade portfolio exports.
First external builders live, with an onboarding playbook.
Year three
Multi-project learning: standards analytics and repeated-issue detection.
Capture, PM summary, closeout, and retrieval copilots: friction removers, not decision makers.
Self-serve admin depth and cleaner onboarding at scale.
Grow it, keep it premium, or keep it as Altoria's edge, decided from data.
By quarter twelve: core to how Altoria builds, sticky with PMs and trades, and a defensible standards moat.
Priced for crews, not seats in an office.
The pricing model Stratum is being built around. Final numbers lock with our first design partners: waitlist members get them first.
