Every Top 30 list is built the same way: original ideas, visible results and the votes of people these thinkers have actually reached. Pick a field, see who made it, and vote for the ones who changed how you work.
Each list ranks the world’s top speakers, trainers and consultants in that field. Voting feeds next year’s ranking.
Originality, impact, practicality, presentation, publications and guru factor, scored by our research team.
