Secure Data Utilization

Keep your sensitive information secure while still benefiting from AI capabilities. Our fine-tuning approach ensures your proprietary data never leaves your security perimeter while creating powerful AI assistants that accurately represent your internal knowledge, policies, and procedures.

How It Works

While companies like OpenAI and Microsoft spend billions training their models on the public internet, you can spend just thousands to fine-tune less than 1% of a model on your proprietary data—creating powerful, specialized AI that keeps your information private.

Case Study: Technical Support Transformation

This illustrative case study demonstrates the potential business impact of AI fine-tuning for technical support operations.

A manufacturing company with complex equipment was struggling with high support costs and long resolution times. Their experienced technicians were overwhelmed with calls, while new hires faced steep learning curves.

By fine-tuning an AI model on their technical documentation, service manuals, and past support ticket resolutions, they created a specialized support assistant that could:

  • Provide step-by-step troubleshooting guidance for specific equipment models
  • Suggest the most likely solutions based on symptom descriptions
  • Reference exact pages in technical manuals for detailed procedures

Projected Results: 50-60% reduction in resolution times, 40% decrease in escalations to senior technicians, and significant improvements in customer satisfaction scores.
