Beyond the Hype Gap.
Built for Everyday Work.

Many generative AI prototypes never become useful products. We help you move from an experiment to secure AI that works in daily operations.

The Implementation Gap

What most "AI Agencies" deliver:

  • Public AI APIs

    Sensitive business data may leave your controlled environment.

  • Unreliable Answers

    Unchecked AI output can create legal, day-to-day, and brand risk.

  • Point Solutions

    Isolated chatbots that don't talk to your ERP or CRM.

The Coretus Standard

Ready for Daily Work:

  • Private LLMs in your private cloud

    Keep your models, data, and infrastructure under your control.

  • RAG with Answer Checks

    Multi-step verification pipelines that eliminate made-up answers.

  • AI-driven Automation

    AI assistants that execute workflows across legacy silos.

Eliminate Risk. Create Value.

Private RAG Platform for
Business Finance

Legacy LLM attempts failed due to "unreliable answers" and inability to cite internal regulatory PDFs with precision.

Built a Hybrid Vector-Graph RAG system. Enabled sub-second retrieval across 2M+ docs with private cloud hosting with strong data protection.

"Coretus delivered a reliable AI core. We no longer worry about made-up answers; we worry about how fast we can scale it."

Ways to Work Together

AI Partnership Models.

Choose the partnership model that fits your budget, roadmap, and internal team. You keep full ownership of the resulting IP.

AI Security

Practical
AI safeguards.

AI Solutions must balance useful results with real risk controls. We add clear verification rules to model workflows so safety and compliance are part of the system.

Verified Outputs

Multi-step RAG verification pipelines that cross-reference model outputs against your "Ground Truth" data to eliminate made-up answers.

prompt attack protection

Protection against prompt injection and data-poisoning attempts, helping keep the model and connected systems safe.

private cloud protection

Models run inside your environment. Training data and model weights stay within your cloud boundary, giving you control over data access and location.

AI Questions

Frequently Asked
AI Questions.

Model Identity
GenAI & LLM Specific

Model Weight Control

Yes. You own the custom model weights, fine-tuning logic (PEFT/LoRA), and data adapters created for your project.

Training Data Privacy

AI processing can run entirely inside your private cloud, so private business data is not sent to public model training systems.

Reducing Made-Up Answers

We implement Hybrid Vector-Graph RAG verification. Every model output is cross-referenced against your "Ground Truth" docs with mandatory factual citations.

Prompt Injection Defense

Our squads embed Adversarial Prompt safeguards to prevent jailbreaking and data-poisoning, protecting your AI from malicious external exploitation.

Token Economics & ROI

We optimize for Inference Efficiency. We build model quantization and caching strategies to slash your compute operating costs by up to 60% compared to baseline.
