Why CLEVAIR

Built by leaders who understand HTA strategy, execution, and delivery

CLEVAIR combines domain expertise in market access and HTA with the product discipline needed to turn complex workflows into reliable execution. The result is shaped around real delivery pressure, not generic AI experimentation.

Founding rationale

Why CLEVAIR exists

CLEVAIR was built for teams that already understand HTA methodology but still lose time between evidence strategy, scope decisions, drafting cycles, and review feedback.

Our mission

Help HTA teams move from fragmented preparation to confident strategy development and execution. CLEVAIR brings evidence, comparator logic, drafting, and review into one governed working environment so teams can improve delivery speed, traceability, and decision quality.

Our vision

Build the reference execution approach for HTA and JCA work in Europe: one where scientific rigor, operational speed, and controlled collaboration reinforce each other. The goal is not to replace expertise, but to help expert teams scale execution without losing quality, transparency, or control.
