Pros
Junior, less experienced, and some senior lawyers may be able to land some engagements to list on their resumes. One or all may even help them find a permanent role or more temporary roles, but most likely they will spend considerable time without an engagement - "on the beach" - as it is known.
Cons
The harsh reality of platforms like Axiom is that they market themselves as an elite executive sandbox, but in practice, they often operate as high-volume, low-margin staffing agencies. This is Axiom. They capture the premium from the client, pay the attorney a relatively low hourly wage (your plumber and electrician probably make more), leaves the attorney with commoditized commercial contracts (NDAs, vendor MSAs), and trap true C-suite legal minds in a bureaucratic layer with minimal benefits.
