The pre-construction phase has been broken for decades.
We're building the operating system that fixes it — for the architects who design, the homeowners who invest, and the builders who execute.
Our mission
Make the gap between design and construction disappear.
Every residential renovation above a certain scale involves three parties who never share the same system. The architect works in drawings. The homeowner works in email. The builder works in gut feel and change orders. GrandStead is the shared record that connects all three — from the first concept to the final handoff.

The founding story
It started with a $400K renovation that almost fell apart at handoff.
The architect had done everything right. The design was resolved. The selections were made. The client had approved every line item. Then the builder came on board — and spent the first three weeks asking questions that had already been answered.
The problem wasn't the people. It was the infrastructure. There was no shared system. No single source of truth. The architect's drawings lived in one place, the budget in a spreadsheet, the selections in an email thread, and the client's approvals scattered across text messages.
GrandStead exists because that story repeats itself on every high-end residential project in the country. We're building the platform that ends it.
How we think
Four principles we don't negotiate on.
The professional's tool first
GrandStead is built around the architect's workflow. Everything else — the homeowner portal, the builder interface — is downstream of that.
Shared record, not shared access
Every party sees what they need to see. The architect controls what's shared and when. The homeowner sees their project. The builder sees the handoff.
Honest about what we are
Phase 1 is pre-construction. We're not a construction management tool yet. We're building toward it — and we'll tell you exactly where we are.
Priced around the work
One project fee. No per-seat pricing. No surprise charges for inviting your client or your builder. The professional pays; everyone else is free.
Five-year roadmap
Where we start. Where we're going.
The pre-construction record
Scope & budget, selections library, builder RFP, homeowner approval, and zero-friction handoff. The complete pre-construction operating system for architects and designers.
- Scope and budget tracker with line-item history
- Selections library with homeowner approval workflow
- Builder RFP and bid comparison
- Handoff package — everything the builder needs on day one
- Homeowner portal, free forever
The shared record extends into the build
The project record doesn't end at handoff. Phase 2 extends GrandStead into the construction phase — schedule, change orders, draw requests, and site documentation.
- Construction schedule with milestone tracking
- Change order management with client approval
- Draw request and payment tracking
- Site log and photo documentation
- Punch list and closeout workflow
The network effect
A vetted network of architects, builders, and suppliers — connected by shared project history. Predictive budget variance, AI-assisted change orders, and market benchmarking.
- Vetted trade and supplier network
- Predictive budget variance modeling
- AI-assisted change order analysis
- Market benchmarking and cost data
- Cross-project intelligence for practices
For investors & partners
A $526B market with no operating system.
U.S. residential renovation and improvement spending exceeds $526B annually. The top decile of projects — renovations above $150K — represent a disproportionate share of that spend and the highest concentration of professional involvement. These are the projects where an architect is hired, where selections are made, where a builder is vetted. And they run entirely on email, spreadsheets, and tribal knowledge. GrandStead is the first purpose-built platform for this workflow.
