We choose channels by practical usefulness over motivation, the founder/operator credibility of the people behind them, relevance to startups specifically, publishing consistency, and the quality of their examples and case studies. We avoid channels that are mostly hype.
Each channel's top and latest videos refresh automatically every week. The channel selection itself is reviewed and updated by hand, most recently in June 2026. We drop channels that go inactive or drift away from startup topics.
