About Stage5
We build whereconstruction actually happens.
Stage5 is an Israeli company building AI agents that live inside WhatsApp and Telegram - the tools the field already uses. Since 2026 we have pointed that at one industry: construction. Three construction companies now run their daily site record on our agent.

How we got here
We started Stage5 so that people without a developer could build their own AI assistants. We spent years learning something specific in the process: how to make an agent behave inside a group chat, where nobody fills in forms and nobody reads instructions.
Then the CEO of a construction company described the thing that breaks every site - the day happens, and then it is gone. We had sketched that same idea with him back in 2019. This time the technology had caught up, and the skill we had built turned out to be exactly the one the problem needed.
The two of us
Alon Weiss
CEO & CTO
Builds the agents. Has spent the last years on what it takes for an AI to hold a real conversation inside WhatsApp.
Nadav Yeheskel
COO
Runs the field side. Sits with site managers, foremen and back offices, and brings back what actually breaks.
