American brain coach, author of Limitless and host of the Kwik Brain podcast, who sells memory, speed-reading and learning training through Kwik Brain and Mindvalley.
Jim Kwik is an American brain coach, author and podcaster who teaches memory improvement, speed reading and accelerated learning. According to Wikipedia, he was born on July 29, 1973, in Westchester, New York. His own account, repeated in interviews such as a 2015 NextShark profile by Benny Luo, is that a head injury in kindergarten left him with learning difficulties that he later worked through by studying how learning and memory work.
He founded Kwik Learning, which Wikipedia dates to 2001 as a company and 2009 as an online platform; its course offering now trades under the Kwik Brain name at kwikbrain.com. He also hosts the Kwik Brain podcast, which began in 2017 and is distributed on Apple Podcasts and Spotify.
His book Limitless: Upgrade Your Brain, Learn Anything Faster, and Unlock Your Exceptional Life was published by Hay House in April 2020 and, according to Wikipedia, appeared on the New York Times, Wall Street Journal and USA Today bestseller lists. Hay House has since published a Limitless Expanded Edition (ISBN 9781401968717) with new chapters on AI, nootropics and work, and a companion title, Limitless Daily: 366 Keys to Train Your Brain, Master Your Mind & Win Every Day.
His main YouTube channel, linked from jimkwik.com, showed 1.94 million subscribers on September 13, 2026. His website also links to Instagram, Facebook, LinkedIn and X accounts under the jimkwik name. A TikTok account @jimkwik showed 212,100 followers, but it is not linked from his websites, so that figure is not counted here.
What he sells has changed in 2026. Kwik Brain's classic self-paced courses (Kwik Reading, Kwik Recall, Kwik Thinking, Kwik Productivity, Kwik Confidence and Kwik Student) closed to new buyers on June 30, 2026; according to the Kwik Brain site, existing buyers of the final bundle keep access until December 31, 2026. The offer that remains open is Kwik Success, a membership with monthly live coaching sessions with Kwik, a book club, a course library and an online community, listed at $77 per month or $697 per year with a 30-day money-back guarantee. He also teaches Superbrain, a 30-day program on the Mindvalley platform that is only available as part of a paid Mindvalley membership; Mindvalley's program page does not show a price. He takes corporate and event speaking bookings through a request form on his website, with no published fee.
His website lists organizations such as the U.S. Air Force, Nike, Google and Marriott as clients, and interviews name public figures he has worked with. These claims come from his own promotional material and interviews based on his account; Mentor Explorer has not found independent confirmation of them. The 2015 NextShark profile is an interview, not an independent review of his methods. Mentor Explorer has not found press coverage from a major outlet that examines his courses specifically, searching news results on September 13, 2026. An attempt to search the FTC website for Kwik Learning on the same date returned an error, so the absence of FTC action is not confirmed.

The same fields, side by side. No verdict: you decide.
An American brain coach born in 1973 in Westchester, New York, according to Wikipedia. He founded Kwik Learning (now sold as Kwik Brain), hosts the Kwik Brain podcast and wrote Limitless, published by Hay House in 2020.
His standalone Kwik Brain courses stopped taking new buyers on June 30, 2026. The Kwik Success coaching membership is listed at $77 per month or $697 per year on kwikbrain.com. His Superbrain program is only available through a Mindvalley membership, and Mindvalley's program page shows no price.
Limitless (Hay House, 2020), a Limitless Expanded Edition with added chapters on AI, nootropics and work, and Limitless Daily: 366 Keys to Train Your Brain, Master Your Mind & Win Every Day, both also from Hay House.
What can be verified: he runs a real company, Kwik Brain, with a published refund guarantee, and his book was published by Hay House. His client list, including companies and celebrities, comes from his own website and interviews and has not been independently confirmed. No major-outlet investigation of his courses turned up in news searches on September 13, 2026.
Mentor Explorer shows reviews from its own users on this page and does not summarize third-party review sites. The press found is interview-based, such as a 2015 NextShark profile, and an FTC website search attempted on September 13, 2026 returned an error, so no regulatory check could be completed.
