AI engineering studio
We build AI agents and the systems around them.
LightBit is a senior engineering team that designs, fine-tunes and ships AI that runs in production — not just in a demo.
What we do
Four things, done properly.
- 01
AI engineering
LLM features built into your product, with evaluations, monitoring and cost control from day one.
- 02
Agents & agentic systems
Tool-using agents and multi-step workflows on LangGraph and MCP that complete real work end to end.
- 03
Fine-tuning
Open and hosted models adapted to your data and domain when prompting alone stops being enough.
- 04
AI architecture
Model choice, retrieval, infrastructure and guardrails — designed before you commit budget.
