Felesh · Field notes
We turn systems into intelligence.
Honest writing from the team building Felesh — whether you're weighing AI for your business, or building it yourself.
For your business founders · owners · teams
Considering AI for your organization? Here's how we think, what we build, and what we ship.
Insights
How we think about AI in business
Our vision and positioning, and the real economics — how we cut model-serving cost, when to fine-tune vs. RAG, why focused beats big.
Use cases
What AI can actually do — and where we apply it
Capability deep-dives: agents that act safely, reliable document processing, triage, audit-ready systems. The idea, not the client.
Our way
From systems to intelligence
Instead of replacing the software you already run, we make your existing systems intelligent from within.
