It's labor ($50T+). ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 SEE THE NEXT $1T COMPANY FIRST The next Anthropic isn't hiding. It's already in CUFinder. The CUFinder Company Revenue Filter slices 500M+ B2B records by exact revenue band: 🔹 $1M → $10M → early movers 🔹 $10M → $100M → scale-ups about to break out 🔹 $100M → $1B → pre-IPO, pre-acquisition gold 🔹 $1B+ → enterprise giants Combine with industry, country, employee count and growth rate.

We tracked the Top 20 most-followed people on LinkedIn — every single year from 2016 to 2026. The story is wilder than you'd think. 👇 ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📈 THE GIANTS WHO HELD THE THRONE In 2016, Richard Branson 🇬🇧 ruled with 6.5M followers. Today? He's #2 with 18.6M. The new king is Bill Gates 🇺🇸 — who climbed from 2.5M → 40.3M. That's a 16× explosion. 🤯 Behind them stand the steady titans: 🔹 Satya Nadella — 12.0M 🔹 Jeff Weiner — 10.4M 🔹 Arianna Huffington — 9.6M Proof that consistent presence beats viral moments. Every. Single. Time. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 💡 THE EARLY THOUGHT LEADERS (2016–2018) The names that BUILT the LinkedIn we know today: ✦ Jack Welch ✦ Deepak Chopra MD (official) ✦ Mark Cuban ✦ ✦ Gretchen Rubin ✦ David Edelman ✦ Craig Newmark ✦ ✦ Lou Adler ✦ Robert Herjavec 🇨🇦 ✦ Jeff Weiner Haden ✦ ✦ Daniel Burrus ✦ Bernard Marr 🇬🇧 ✦ Barbara Corcoran ✦ ✦ Travis Bradberry ✦ Eric Ries ✦ Daniel Goleman ✦ Some are STILL in the top 20. Others got eclipsed by the next wave. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌊 THE 2020 SURGE The pandemic flipped LinkedIn into a thought-leadership powerhouse. Suddenly, these voices broke through: ▸ Tony Robbins ▸ Justin Trudeau 🇨🇦 ▸ Melinda French Gates ▸ Ian Bremmer ▸ Narendra Modi 🇮🇳 ▸ Adam Grant ▸ Simon Sinek ▸ Guy Kawasaki ▸ James Caan CBE Caan 🇬🇧 Authors. CEOs. Heads of state. LinkedIn stopped being a résumé site — and became a media platform. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🚀 THE NEW WAVE (2022–2026) The latest climbers prove LinkedIn rewards depth over decades: 🌟 Dr. Brigette Hyacinth Hyacinth 🇹🇹 🌟 Anthony J James 🇦🇺 🌟 Brené Brown 🌟 Kevin O'Leary 🇨🇦 🌟 Gary Vaynerchuk 🌟 Derek Shen 🇨🇳 🌟 Lin Zhengang 🇭🇰 🌟 Barack Obama 🇺🇸 (yes, the LinkedIn debut hits hard) The biggest individual jump? 👉 Adam Grant: 200K → 5.4M in 10 years. The recipe wasn't follower hacks. It was original ideas + relentless consistency. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔍 SO HOW DO YOU FIND THE NEXT BREAKOUT VOICE?
