AppEx.ai manages the design process in construction and ensures that cost and schedule targets are met.
AppEx.ai monitors project health and keeps projects on track.

Avoidable surprises cost owners and general contractors millions of francs. AppEx.ai monitors project health, manages the planning process with AI support, and proactively highlights project risks.
AppEx.ai is the successful evolution of the AppEx software, which has been in use by forward-thinking companies in the Swiss construction industry since 2020.

Hello,
I'm Chris, CEO of Appex AI.
There was a time when construction planning meant: printing out bar charts, pinning them to the wall, and hoping everyone stays on the same page. Coordination ran through phone calls, WhatsApp groups, and endless Excel spreadsheets being sent back and forth. Somehow, the buildings still got finished.
But the cracks were always there. Missed deadlines, overlapping trades, cost overruns that only surfaced when it was too late. Not because people didn't work hard — but because the tools couldn't keep up.
We're at a turning point right now. Just as ATMs freed bank tellers from repetitive transactions, AI can free project managers from daily firefighting: manually updating schedules, following up with subcontractors on construction progress, and discovering conflicts when they've long become problems.
We built this AI planning assistant because we kept seeing the same pattern in construction projects: schedules that were outdated as soon as they were printed. Coordination gaps between trades that led to costly delays. And critical risks buried in data that nobody had time for.
From initial planning to handover, the assistant supports every step: creating realistic schedules, detecting conflicts before they arise, matching progress against the plan in real time, and giving project managers the answers they need — without having to search through five different systems.
Most construction companies know they need better planning tools. But the solutions on the market are either built for tech companies, take months to implement, or require the entire team to change how they work.
That's not how it should be.

AppEx.ai is a virtual coach that guides the design process using AI — drawing on 3,000 insights from real-world projects.
AppEx.ai tracks the status of each project — progress, pending decisions, and planning status. Each company receives its own isolated data environment containing company-specific knowledge and its own projects.
AppEx.ai translates a leading process model into understandable language. Dependencies between disciplines, phases, and milestones are clearly highlighted so that everyone involved knows what needs to happen and when.
Phase-specific review of all deliverables for quality and readiness for decision-making. AppEx.ai ensures that documents meet the requirements of the respective project phase.
Based on insights from thousands of projects, AppEx.ai recommends concrete measures for scheduling and achieving goals, from the schematic design phase through to handover.
Real-time monitoring of project health. AppEx.ai proactively detects deviations, sends AI alerts, and provides concrete recommendations before small delays turn into major problems.
Customizable to your company's needs: Processes, content, and lessons learned are fully adaptable to your way of working. Your virtual coach knows your projects and speaks your language.

Our technology is built on a proprietary RAG Knowledge Base specifically developed for the Swiss construction industry.
