FlowManual builds AI software for construction contractors' back office. The platform reads PDF drawings and contract packets to produce mechanical, piping, ductwork, and concrete takeoffs, feeds accepted quantities into an editable estimate workbook with formulas and unit costs, and compares bid, contract, and invoice documents for scope gaps and price deviations. Its buyers are general contractors and mechanical, electrical, and plumbing subcontractors working through preconstruction and procurement.
The company launched in Y Combinator's Summer 2026 batch and reports the product live with engineering teams at general and MEP contractors, with document imports from OneDrive, SharePoint, Google Drive, Procore, Dropbox, Egnyte, Docusign, and Autodesk Construction Cloud. FlowManual is San Francisco-based and runs on a freemium model with a daily usage allowance on the free tier and sales-led custom pricing for Pro accounts.
