BUILD SYSTEMS THAT SCALE WITH YOUR BUSINESS. Your AI Transformation Partner. With 7+ years of hands-on experience in AI, automation, and data-driven systems, OptiSmart.AI helps growth-focused companies design, implement, and scale high-impact solutions — without the technical headaches. You probably have work in your business that a machine should be doing by now: lead follow-ups, invoice processing, answering the same customer questions every day, copying data between tools. We build AI agents and automations that take that off your plate, hosted in the EU and fully GDPR compliant. OptiSmart.AI brings 7+ years in AI and automation delivered across different industries. What we build AI Agents & Chatbots: Private assistants trained on your own documents (RAG), with memory, connected to your CRM, email and internal tools. Support, sales and voice agents that work 24/7. n8n Workflow Automation: Lead generation, reporting, meeting summaries with follow-ups, email analysis and fraud detection, CRM and API integrations. Every workflow is built with proper error handling, so nothing breaks quietly at 2 a.m. Document & Invoice Automation: OCR and AI parsing of PDFs, receipts and contracts. We provide ZUGFeRD/XML output for German invoicing, synced to Excel or Google Sheets. Custom AI Models: Fine-tuning and training on your own data, MCP integrations, and private LLM setups on AWS, Azure or your own servers. AI Marketing Videos: Product ads, explainers and short social media clips made with AI. You can test several versions without a production budget. Websites & Online Stores: Custom-built e-commerce stores and business websites. They’re fast, mobile-friendly and easy for you to manage yourself. How we work Every project starts with a short call about your goal. You get a clear plan, timeline and price, then a working proof of concept early so you see results before going further. You get weekly updates along the way and a full handover at the end, so everything is yours. GDPR first For European clients, all systems are hosted inside the EU. Your data stays yours and never leaves EU borders.

We’ll reply with an honest take on whether AI can fix it and what it would take. Für Kunden aus dem DACH-Raum Wir entwickeln KI-Agenten, Chatbots und n8n-Automatisierungen, die Ihrem Team wiederkehrende Arbeit abnehmen. Dazu gehören Lead-Generierung, Kundensupport, Meeting-Zusammenfassungen sowie Dokumenten- und Rechnungsverarbeitung mit ZUGFeRD/XML. Außerdem erstellen wir KI-Marketingvideos, Websites und Online-Shops. Alle Systeme werden DSGVO-konform in der EU gehostet, und Ihre Daten bleiben vollständig bei Ihnen. Beratung und Zusammenarbeit gerne auch auf Deutsch.
