Already running. Now a platform.
The core already runs in production inside a partner-led advisory firm, on live client engagements, for over a year.

Emily Chen, CPA
Managing Partner, Evergrow Advisory. Big Four trained. Leads a live practice across IPO readiness, SEC reporting, technical accounting, SOX and audit support.
Two years of encoded procedures, before the first line of platform code.
Lumistead grew out of Evergrow Advisory, a Big Four trained firm serving a bilingual US and Asia client base. The firm built an internal AI operating system to run its own engagements — cash reconciliations, PP&E rollforwards, ASC 842 schedules, disclosure checklists, PBC triage, pre-delivery quality gates.
The procedures encode partner-level review rules learned on real audits and filings. Lumistead is that system, opened to the companies that need it most and cannot hire for it.
