Quality by design
Rubrics, calibration, and review loops are engineered into every project — not bolted on at the end.
Lona connects human brilliance with artificial intelligence.
We bring together senior practitioners across medicine, law, engineering, and dozens more domains — then pair their judgement with the labs building the next generation of AI.

Why we built Lona
The gap between clever and useful is expertise
Frontier models impress in demos. They stumble in production — on edge cases, regulated domains, and tasks that require real judgement. That gap is not closed with more compute.
Lona exists to make expertise first-class infrastructure. We curate the practitioners, design the rubrics, and run the quality programme that turns impressive outputs into dependable training signal.
Operated by Ployos, the team has spent the better part of a decade building expert networks and evaluation programmes for AI laboratories — sometimes inside labs, sometimes for them.
