You mean in the Q3 call when he thought the questioner was referring to technology partner pilots, not enterprise customer POC's/pilots?
The gov't customer PR in Q4 referenced dozens of pilots across multiple verticals so imo the matter of what % of "pipeline opportunities" today are pilots is a moot point. I never worked IT sales but I wouldn't think a prospect is in the "sales pipeline" until they at least do a POC or possibly even advance to a pilot.
