Georgetown CS professor and NYT-bestselling author of Deep Work; 352k subscribers and 749 videos, publishing several times per week (2026-08-03, 07-30, 07-27, 07-20 verified live). Research- and book-grounded rather than hustle content.

Ex-Googler product marketer, 1.84M subscribers, 310 videos, last upload 2026-07-21 verified live. Unusually high production quality and concrete workflow demos; roughly one video every three weeks in 2026.

Author of Building a Second Brain; 387k subscribers, 256 videos, last upload 2026-07-09 verified live. Adjacent to time management rather than core to it — the right entry when time is lost to re-finding information, not to scheduling. Bursts of weekly uploads separated by quiet stretches.

Computer scientist (Hamburg/Cambridge, ex-Facebook engineer) with a documented 'complete productivity system'; 285k subscribers, 346 videos, weekly, last upload 2026-08-01 verified live. Caveat: the most recent titles are vlog-style rather than method-driven.

Run by consultancy Büro-Kaizen GmbH; 113k subscribers, 785 videos, weekly and highly current (2026-08-05 Teams/M365 update, 07-21 Outlook out-of-office verified live). Practice-based training content, not motivational filler — the most concrete office-hours time management in the catalog.

Ishikawa Kazuo bills himself as a time-management specialist and lives the premise — he holds five parallel jobs (construction-company finance director, university lecturer, seminar trainer, tax accountant, author). 679 videos, weekly, last upload 2026-08-03 verified live. Small channel (3.7k) but the tightest topic fit in this file; native Japanese captions make it processable by the summary pipeline.

Seiiti Arata's official Portuguese channel: 2.04M subscribers, 797 videos, several uploads per week verified live (2026-08-05, 08-02, 07-29, 07-26). Caveat: the recent verified titles are about cognitive decline and grief rather than time management.

Bestselling Brazilian author with postgraduate training in neuroscience/behaviour; 1.21M subscribers, 1600 videos, weekly episodes verified live (2026-07-30, 07-23, 07-16, 07-09). Some episodes drift toward wealth/mindset framing.

Former Cambridge medic and the most-followed productivity creator (6.67M subscribers, 1400 videos, last upload 2026-08-04 verified live). Caveat recorded honestly: the recent uploads verified live are about financial freedom and YouTube business, not time management — recommend the back catalogue for this topic.

EPITA engineer and ex-Qonto product manager; 312k subscribers, 252 videos, weekly, last upload 2026-07-31 verified live. Caveat: the 2026 output is squarely AI/automation tooling rather than general productivity — valuable when the time problem is repetitive work worth automating.

653k subscribers, 330 videos, last upload 2026-07-31 verified live. Fastest route to the underlying methods when the viewer has no time to read the books; uploads arrive in batches rather than on a steady rhythm.

231k subscribers and 1200 videos; weekly rhythm confirmed live (2026-07-26, 07-19, 07-12, 07-05). Ten-plus years of book summaries with a reflective, non-hype framing ('500 livres plus tard, j'ai compris pourquoi rien ne changeait').

Danyi István channel and the only Hungarian-language result that is genuinely about time management rather than general self-development; 196 videos, native Hungarian captions. Honest caveat: the channel description promises weekly videos but the real rhythm is monthly at best — last upload 2026-06-15, 52 days before verification.

1.22M subscribers, 154 videos, last upload 2026-07-03 verified live. Covers the half of the time-management problem that app tutorials miss — motivation, avoidance and self-sabotage — with a self-deprecating, anti-hustle framing. Roughly monthly output.

825k subscribers and 196 videos; live Japanese sources credit it with setting the standard for the 本要約 (book-summary) genre, and the animated format compresses a book into minutes for viewers with no reading time. Native Japanese captions. Two honest caveats: the rhythm has slowed to roughly monthly (last upload 2026-05-07, 91 days before verification — inside the current-year window but far from fresh), and the recent verified titles lean toward general self-development and money anxiety rather than time management proper.

1.29M subscribers and 174 videos; runs a structured methodology and a companion site (fullperception.com). Honest caveat: the rhythm is slow and uneven — last upload 2026-04-28, 100 days before verification, which sits inside the current-year activity window but well past a fresh cadence.
