Verena AI Consulting
AI built by people who understand the models.
We handle the full stack. From training and fine-tuning to production deployment. No shortcuts, no black boxes.
What we do
What we do.
AI Strategy & Scoping
Not every problem needs a custom model. We figure out what's actually worth building and what isn't, before anyone writes a line of code.
Custom Model Development
When off-the-shelf models don't fit, we build or adapt them. Training from scratch, fine-tuning, RLHF. Whatever the problem calls for.
AI Systems & Agents
Agents, pipelines, and LLM-powered workflows that reduce real workload. Built to be reliable in production, not just convincing in a demo.
Deployment & Optimization
We take working AI from prototype to production. Optimized inference, API design, monitoring. The part most teams underestimate.
Why us
We understand the models, not just the APIs.
The person who sold you is the person who builds.
From research to production, without losing either.
