The operating system for construction: project management, construction accounting, analytics and AI agents on one data core. Project and company workflows share context; review and reconcile each handoff. We are building it now with contractor input.
01The problem
Most contractors run projects in one system, accounting in another and forecasting in spreadsheets. The same change gets typed again at every hand-off, by a different person, on a different day.
Each re-key is a chance for the numbers to disagree. Month-end turns into reconciling before anyone can answer the only question that matters: are we making money on this job?

Shared context, reviewed at each handoff.
Sample job: Riverside Medical Center, CO #14 (fire dampers). Illustrative.
02What's in it
Four systems on one data core. Project Financials and company Accounting are available; items marked Planned are not available yet.
Project financialsProject Financials: budgets, commitments, changes, pay apps and project cash. Company Accounting: ledger, AP, AR, payroll and controls.
AnalyticsAnalytics is in preview. Locked WIP and historical AR aging remain unavailable.
AgentsPlanned: AI that drafts and checks work on your real records: match an invoice to its PO, flag a missing lien waiver, draft a CO from an RFI. A person approves every action.
One data coreProject records connect related work. Review the project pay app and cash alongside company Accounting; locked WIP is unavailable.

03How founding contractors take part
A small cohort of general contractors, specialty contractors, owners and finance leaders.
First access to planned featuresFounding contractors help shape future features.
A direct line to the teamWorking sessions with the people building it, on a cadence that fits your schedule.
A say in what shipsYour workflows set the priorities. What you need on Monday morning is what we build next.
Pricing before you commitNothing to apply and no obligation. Pricing is shared with you before you commit to anything.
What we ask in return: a few honest working sessions, a walk-through of how a CO, a pay app or month-end really runs at your company, and straight answers when something is wrong or missing. You keep running your current systems the whole time.
