Castledot is an Australian software company based in Sydney. We build Lystra, a field operations platform for contractors who manage crews across multiple worksites. Our mission is to help construction, utilities, and trades companies replace spreadsheets, WhatsApp groups, and paper forms with one clear system. Lystra brings scheduling, timesheets, materials, and tools together — so teams can focus on the work, not the admin. Founded in 2025, Castledot serves contractors across Australia, New Zealand, the UK, and the US.
