Our mission
Eliminate the manual work that slows businesses down.
Software and AI that take over tedious, error-prone work — so your people can focus on customers and growth.
Our vision
A Southeast Asia where every business runs on automation.
Software does the routine. People do what only people can.
HeySheep is a Singapore-headquartered software and AI engineering company with an R&D engineering centre in Da Nang, Vietnam. We build custom software, automate manual business processes with AI, and make our own products: Collie, xDocs and HeyInvoice.
