AI-native customer operations.
Kroonen AI builds the Libre ecosystem: AI support, local LLM interfaces, terminal-native agent tools, Twilio-powered phone systems, and model research for small teams that refuse bloated SaaS stacks.
From model research to real products
The same lab that trained Genesis also ships practical tools: chat, docs, terminal agents, phone, and customer workflows.
What We Do
AI products, communications systems, and local-first infrastructure — from prototype to production.
Pre-Training from Scratch
Training language models from scratch on consumer GPUs. Custom architecture, tokenizer, and 60B token multilingual dataset - no datacenter required.
Model Fine-Tuning
Custom fine-tuning of open-weight models for your specific use case, brand voice, and domain expertise.
Safety Evaluation
Comprehensive model evaluation aligned with frontier lab methodologies. Red team testing and benchmark analysis.
Applications & Communications
Custom web, mobile, and telephony applications with AI integration. React, TypeScript, Twilio, Cloudflare Workers, and native iOS.
Red Team & Security
Adversarial testing of AI systems and infrastructure. Prompt injection, jailbreak resistance, model extraction, and CBRN safety assessments.
AI Agents & Orchestration
Design and deployment of AI agent systems that work alongside your team. Multi-model orchestration, local deployment, and custom integrations.
Featured Projects
The Libre ecosystem: support chat, local AI, terminal agents, and programmable communications.
