The short answer
To find YouTube influencers in 2026, start with niche searches on YouTube itself, mine the "recommended channels" rail to expand, validate growth with Social Blade (free), then filter the list by view-to-subscriber ratio and average view duration. When you hit ~50 channels and need more, an influencer database like Hubfluence takes you from 50 to 5,000 matched YouTube creators in a single search.
