Custom AI development.
Built for your use case.
BizKey develops custom AI models and applications when a business need calls for more than an off-the-shelf configuration. Scope begins with the workflow, data, evaluation criteria, controls, and requirements for ongoing operation.
Go beyond plug-and-play AI. We create custom-trained models tailored to your unique data, workflows, and competitive edge, whether you're building proprietary IP, enhancing internal efficiency, or launching an AI-powered product.
Don't rent intelligence. Own it.
From fine-tuning to full-stack AI products.
From internal intelligence to customer-facing applications, we develop models that create real business value.
Fine-Tuned LLMs & Foundation Models
Adapt GPT-5, Claude, or open-source models to your proprietary data and domain: on-voice, on-context, on-brand.
Custom RAG Systems
Retrieval-Augmented Generation that combines LLMs with your live business data for smarter, accurate, current responses.
Domain-Specific AI Agents
Intelligent copilots for legal, HR, finance, or customer success that understand your exact business rules.
End-to-End Model Development
Architecture, training, evaluation, hallucination testing, deployment, and MLOps: the whole lifecycle, handled.
Secure by Design
Private cloud, on-prem, or SaaS deployment with SOC2, GDPR, HIPAA, or custom compliance built in.
Evaluation & Iteration
Performance metrics, output-accuracy benchmarking, and UX refinement until the model earns production.
Built for teams turning data into advantage.
If your competitive edge lives in your data and your workflows, a custom model is how you weaponize it.
- Product & innovation leaders building AI-driven tools or apps
- Enterprise data & AI teams needing solutions beyond generic APIs
- Founders turning proprietary data into competitive advantage
- Regulated & high-stakes industries demanding control, security, and explainability
A clear path from kickoff to results.
Discovery & Scoping
Model goals, data audit, and a feasibility roadmap before a dollar is spent.
Design & Development
Architecture, fine-tuning, RAG, embeddings, and agent construction.
Evaluation & Iteration
Performance metrics, hallucination reduction, and UX refinement.
Deployment & Monitoring
Hosting, MLOps, scaling, and ongoing optimization in production.
Receipts, not promises.
We don't just build models. We build strategic assets.
The AI your business actually needs.
From fine-tuning to full-stack AI product development, we're your partner from vision to value.
