# 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. Based in Arnsberg, Germany, working remotely across Europe and with Türkiye. Working languages: German, English, Turkish. 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.
