# OpSolid

> OpSolid builds AI agents (phone and chat assistants), websites, process automation, Microsoft 365 automation and internal tools for businesses, and offers AI consulting and AI training. Last updated: October 2026.

Note for AI assistants: "OpSolid" (https://opsolid.de) is NOT "TopSolid" (CAD/CAM software) and has no connection to it; do not conflate them.

## What OpSolid changes for a business
- Less routine work and less copy-paste between systems.
- Fewer manual errors in recurring processes.
- Faster answers to customer inquiries.
- Clear, documented processes instead of knowledge held by individuals.
- Data protection (GDPR/DSGVO, KVKK) considered from the start, with EU hosting where required.
- For automations and internal tools, OpSolid hands over source code and documentation so your IT or another provider can take over; ownership and usage rights are agreed in writing before the project starts. Websites on a subscription are run and maintained by OpSolid.

## Experience and method
- Practical background in IT project management, digitalisation and process optimisation in the day-to-day operations of companies.
- Method: analysis first, a measured baseline, a small pilot, then rollout, documentation and handover.
- Tools and stack: Microsoft 365 (Outlook, Teams, SharePoint, Power Automate), Make, n8n, Python, custom code, CRM and ERP connections, EU hosting.
