Telamont — Sentry for errors in construction documents (opens ycombinator.com)
AI that catches errors between construction drawings, specs and contracts

AI that catches conflicts between construction drawings, specs and contracts before they become disputes (YC Fall 2026).
Telamont connects to SharePoint, Dropbox or Autodesk, pulls in each new project file and checks it against the rest of the project, flagging the exact sheets and clauses that conflict; each finding gets an owner and is tracked to resolution. Modules on its site: risk detection, triage, tracking, notice drafting and RFIs, with Procore, Autodesk, SharePoint, Teams and Slack integrations. Founders Charles Goulet (ex-1Password) and William G. Gagnon (ex-Poka); team of six including hires from WSP and AtkinsRéalis. The launch post says it protects $2B+ of construction today and lists ten contractor customers on its site. Site is in English and French.
