Custom extensions, API integrations, and seamless embedding into your system landscape.
Standard software often covers 90% – we close the last gap. We develop Custom Ingestion, connect PrivateGPT with your tools, and automate workflows.
From API integration to complete custom solutions – we cover the entire spectrum.
We make your systems talk to each other. Whether REST, GraphQL, or webhooks – we connect software with your CRM, ERP, or identity provider.
Often data formats from System A don't match System B. We develop middleware that sits in between, transforms data, and controls processes.
Want to use software features in your own intranet or customer portal? We embed software headlessly and build custom UIs around it.
Save manual work through intelligent automation. We develop bots and scripts that handle tasks automatically.
PrivateGPT enables local LLM usage with your own documents. We integrate it into your existing infrastructure and extend capabilities.
Via the API we connect PrivateGPT to your systems: Chat completion, document ingest, and context retrieval can be controlled programmatically.
We develop custom ingestion pipelines: Special document types (CAD, contracts, code) are processed with optimized chunking strategies.
The LlamaIndex backend allows deep customization: Custom retrievers, rerankers, and embedding models for domain-specific search.
How we implement PrivateGPT development in practice.
Highly sensitive environments (government, defense) cannot have cloud connections but need LLM capabilities.
Fully offline-capable setup with local models, own embeddings, and airgapped update mechanisms.
Lawyers need to search thousands of documents for relevant passages. Manual review takes weeks.
PrivateGPT with legally optimized chunking and retrieval. Questions in natural language, answers with source references.
Executives receive hundreds of emails daily. Summaries and prioritization are needed.
PrivateGPT integration that analyzes, summarizes, and categorizes emails by urgency – fully on-premise.
Update-safe, scalable, and secure – why you should trust us with your development.
We don't modify the open-source software's source code. Instead, we use official APIs and plugin architectures. Your installation remains updatable and maintainable.
We understand not just the code, but the infrastructure beneath it. Our developers know how queries affect database performance and how to build scalable APIs.
We use modern, type-safe technologies: React, TypeScript, Node.js, Python, Go. Plus PostgreSQL, Redis, and Docker/Kubernetes for infrastructure.
Every line of code is written with security in mind. Input sanitization, secure authentication (OAuth2/OIDC), and compliance with data protection regulations are standard.
Our Tech Stack
From requirements to go-live – transparent and structured.
We review API documentation, analyze your requirements, and identify optimal integration points.
We design the solution: middleware, plugin, or script. Data flows, interfaces, and security concept are defined.
Agile implementation with code reviews, automated tests, and continuous coordination. You see progress in real-time.
Integration into your CI/CD pipeline or hosting on our infrastructure. Documentation and training included.
Let's get technical. We'll assess feasibility and effort.
