How to Generate 8-Figure Revenue at Age 21 (Or Any Age) — Real 4-Hour Workweek Case Studies (#354)

“I think the role of the entrepreneur in the world is to find ways to do things better or more efficiently and then try to do that as many times over with the help of other people.” — Santiago Nestares

Benedict Dohmen and Santiago Nestares of Benitago Group, both 21, met as computer science students at Dartmouth College. Both worked very long hours in the library and suffered from back pain. They began collaborating on a prototype for a product that ended up being called the Supportiback, gathering feedback from members of the Dartmouth community, including a local hospital president and professors and students studying engineering and medicine.

They launched the product on Amazon in the UK, and when it seemed their first small order was in danger of selling out quickly, they arranged financing from their supplier and were off and running. Since then, they’ve entered the US market on Amazon, and are on track for nine-figure revenue in 2019. They have introduced 120 consumer products, and are trying to become an alternative to big consumer products companies through a strategy of applying their successful scale-up strategies to brands they acquire.

Also joining us in this special episode is Elaine Pofeldt (@elainepofeldt), an independent journalist and speaker who specializes in careers and entrepreneurship. She is the author of The Million-Dollar, One-Person Business: Make Great Money. Work the Way You Like. Have the Life You Want, in which she looks at how entrepreneurs are scaling to $1 million in revenue prior to hiring employees.

  1. Great episode. I love the ‘Real 4 Hour Work Week Case Studies’ podcasts! Great idea saying you had a big board meeting!

  2. Black hat amazon listings with fake reviews included from different products and from 2010 on a product you just launched. Part of the growing notorious trend Amazon is trying to crack down on.

    “I have been taking detox for 1 month and it is amazing it has helped me in going more often to the bathroom. I used to be really constipated all the time and now I go more times than ever. This is a great product!!!!!!”

    “Dawn has beautiful illustrations and the simple story brings the reader to a lovely ending. This is why I first bought this book when I was a teen and again as a grandparent.”

    Just go to reviews and click to last review page to see how they changed the color to supportiback 77, 88 etc.

    Good luck with Amazon taking listings down quick over this

  3. Enjoyed this episode and feel inspired by this young, energetic, smart duo. Also will be checking out there product to help with my sore back! The one less than awesome comment I have (and I thought the same on the last episode in which she participated) is I don’t understand what real value Elaine brings to the podcast, Seems like this is simply a way for her to plug her book.

  4. Tim – so happy you did a podcast on amazon FBA

    I got into Amazon in 2013 when moved to New York from Australia to scale a Muse idea that came from the 4 hour work week. (I’ve read your book once per year for the first 5 years)

    Your book and selling on Amazon has changed my life and the quality of my families life, plus this year cracked 7 figures online via Amazon.

    The podcast was fantastic and strongly recommend any entrepreneur to look into the Amazon platform to scale their business

    [Moderator: kind offer removed.]

    Keep up the amazing work.

    1. Peter —

      Thanks for bringing this up. In the last few weeks, our registered barcodes have been unduly used by what we believe are Chinese sellers. Some of their reviews have been attached to our product listings, generating distrust from our buyers and significantly hurting our sales. We are working hard with Amazon to filter those reviews our of our listings.

      If you have any tips or ideas on how to crack down on these reviews, please reach out to us directly via LinkedIn.

      — Santi

  5. Tim – Great case study!

    I would like to know more about going from concept to prototype to production. All the steps involved in between from a concept and converting it to a product.

    – What are the steps involved in getting a prototype made?

    – Do you need an engineer? if yes, what kind? where do you find them?

    – Do you need a CAD design made? if yes who, what etc.?

    – Do you need a patent? if yes, what, how, who etc.

    Any way to expand on this? that would be great.

    Thanks, Richy.

  6. Great interview and notes! What about Intellectual property? Ben and Santi mention tweaking and improving on what’s already out there. What IP did they file for and how did others’ IP factor in?

  7. Tim, I am getting the feeling from the direction of these Case Study podcasts that you and Elaine are potentially going to (or already have) team up for a revised 4-Hour Workweek with a bunk of these sorts of case studies? If not, please do. I would read it. Twice.

  8. Potential Case study?

    Great to hear the stories of people who got inspired by your book and did something about it. I’m one of them.

    Came here as an Illegal emigrant, started driving semi trucks and now a founder of a Inc. 500 company. You’re book started all the passion for success and value creation. I will be always greatful. Thank you Tim!

  9. I clicked the Supportiback link on Amazon and read some of the comments. Most comments do not seem to be related to the Supportiback at all, something must be off/wrong?!!

    1. Hey Marco,

      Thanks for pointing this out. We believe there has been a cross feed of reviews between our listings and other products using our barcodes. For the last few days I’ve been working closely with Amazon to get this sorted out.


      Santi 🙂

  10. This was one of my favorite episodes ever. My friend and I are trying to start our own FBA business while in college and everything discussed was super relatable. I’m even a computer science major. We are going to try and use their method of improving products based on comments. Whether or not we are successful, it will be a fun adventure.

  11. I don’t have anything to add to Troy and gbell12’s comments, but I did want to take a moment to also voice my concern about the tactics being used in the Amazon store by the Supportiback team.

    There’s a big difference in my mind between ‘outworking/outsmarting the competition’ and what appears to be disingenuous algorithmic manipulation of Amazon’s tools.

    It just so happens that I was literally in the market for a lumbar support device, and after hearing this podcast, I thought for sure I would support these guys, but a cursory examination of their pages made it pretty clear something strange was going on. In the end, I couldn’t purchase one of their products, as the incoherent and non-sensical reviews and Q&A gave me no confidence in their company or their products.

    1. Hey Ryan,

      I appreciate you pointing this out. We’ve recently noticed a crossing of reviews between our listing and other products using our same registers barcodes. We’ve contacted Amazon and are trying to resolve this as promptly as possible, as it is currently hurting our sales.

      Hopefully, you’ll be able to read our hundreds of verified purchases’ comments pointing our both the good and bad of our products.

      If you have further info or tips that can help us filter/clean out our listings, we would love to get in touch with you via LinkedIn



      1. HI Santi,

        It would be great if you guys could do a follow up on how you guys managed to sort this out and ways you plan on combating this in the future and also how helpful Amazon are in dealing with your problem.

        thanks Ciaran

  12. I hope I’m still being cool like Fonzie, but it’s important to document what we’re finding. I’m irritated that these guys are probably going to make a lot of money on the “Ferriss bounce” with products that seem to be copies of products that have been around for decades. I don’t see much innovation here. I’m surprised there haven’t been patent “issues” yet.

    Found two more of their products with fake reviews, including a gem about how the product helped a buyer’s beard:

  13. I tried using the coupon code TIM to make a purchase on Charlotte’s Web but there were exclusions. Particularly on the product Tim recommended. I emailed them and they said there was nothing they could do. Did anyone else run into this? I don’t recall Tim mentioning any excluded products but maybe I missed it?

    1. Thank you. The exclusions notice appeared on the Charlotte’s Web website. Please note that the promotion is expired, as of 12/31/18.


  14. I Love Case Study Episodes! Thank you. After pondering a few questions about what to do next, I almost always get direction from one of these episodes.

  15. Great to hear someone praising the book Cashvertising by Free Eric Whitman. Fantastic book, packed full of practical tips to improve your adverts, both online and offline.

  16. Ben and Santiago – I just finished checking out your product reviews on Amazon. Thanks for making me laugh!

    You have combined some of the most exotic – and unrelated – product reviews with your Supportiback listings

    I have a question though: How come that your “color field” descriptions for some of your most exotic fake-reviews are named Supportiback-55 / Supportiback-74 / etc ?

    You claim that Chinese sellers have been manipulating your product listings?

    Then there is the part within the podcast where you openly rave about your Computer Science skills and leveraging web-crawl programs that you coded to boost your sales…

    … and 8-figure sales? Outsch …

    Warren Buffet once said that

    “it takes a lifetime to built a reputation, but seconds to loose it all”…

    Time to cleanup your reviews… I won’t be surprised if your brand has already been flagged by Amazon

    1. That’s pretty bad luck that the alleged “crossing of reviews” crossed to products with fake reviews! I don’t think the review “great” was found helpful by 70 people!

  17. Really great episode showing the 4HWW theory in practice. Would love to hear more case study episodes. Preferably from a greater variety of products that include digital products such as ebooks, online classes etc.

    Keep rocking on, Tim.

  18. I was a little disappointed. Seems like these two are willing to stretch ethical bounds and I was bummed Tim didn’t call them out. For example when they explained how they misled their suppliers regarding their financials to get better terms Tim just laughed.

    1. To your comment, I am reiterating the title of the podcast: “How to Generate 8-Figure Revenue at Age 21″…

      I would be curious if Ben and Santi can proof their claims…

  19. I just came back into your world and remember your generosity. and you have remained fresh which can only mean you are authentic! I enjoy you – thank you.

  20. As a 38 years old, I am feeling a tons of jealousy that two 21 years old are operating on a much more “advanced” brain operation manual, at least a chapter of it 🙂

    Learned a ton, the most valuable episode for me!

  21. Normally a big fan of the episodes and I’ve been binging on quite a lot of your recordings lately. I can say confidently based on my experience that this one had so much potential for me, but fell short. These guys are young and intelligent and honestly you just needed to let them speak, something you do decently well with other guests. Your constant interrupting lost the logical flow of their storytelling which was filled with gems. You greatly overdid your standard “pointing out” trying to bring the points YOU want to highlight. Not only is the constant vocal disclaiming of yours “I promise we will get back to X, Y, Z” a constant theme of your podcasts, it’s unnecessary. Usually I can ignore it due to the low frequency, but by mid episode here you are stealing the show most of the time, constantly interrupting the guys and not letting them tell their stories. I honestly had to turn it off by the 2/3 mark out of frustration. It wouldn’t be so bad if they weren’t telling such a great story and the things they were saying filled with great tidbits. Your “highlighting” quickly turned to be just you stealing airtime, killing any momentum they might gain.

    Again, I thank you for your work and am a big fan of the podcast. Here though, I think you let your weaknesses get the best of you (we all have em) and for me, it ruined the episode.

    I know this was long, drawn out, and pretty strong, but I wanted to give you the feedback because I love your podcast and hope that in the end this feedback is constructive and helps improve things.

  22. Enjoyed this one. The biggest takeaway for me was the scientific approach from the guys. They are humble too and I appreciate that quality especially from such successful young men. Thank you.

  23. This was a great episode …loved it … until I found that these kids are doing a “fake” business. It did not take me more than 10 min to figure out almost all their products are cheap chinese knock offs with a ton of fake reviews. As an retired entrepreneur, my gut tells me their revenue numbers are also fake.

    Sad that they used their Dartmouth education to come up with this. i hope this teaches them that you cant fake it on the internet. Especially Tim Ferriss’s audience … who are generally well educated, tech savvy and above avg IQ. I want to give them a little bit of their own advice. Think feedback … not failure. Perhaps a pivot into the speech business .. where you can tell young entrepreneurs the pitfalls of the faking it on the internet.

  24. Loved this episode Tim! I would love to hear more of these 4 hour work week case studies! Preferably folks who are recently successful and started their businesses within the last 12-36 months!

  25. I have recently finished The 4-Hour Workweek for the second time, along with these case study episodes, and I’m executing step-by-step from the book. I have identified my niche as those interested in self-optimization (not a fan of “self-improvement”) and have designed a Muse based on your book’s principles. I have a design specifically for you and your readers/listeners and would love to send you a mockup of what I’ve created, as your approval is the last critical step before execution. I understand you are crazy busy so if you can’t respond, I totally understand and will continue to move forward with the muse. Keep putting out all your amazing content!

  26. Would love to see more of these case study type resources Tim! Thanks so much for putting this all together!

  27. Amazon FBA is cool and yeah it can definitely make you money, but how who you make the intail amount of money needed to start the Amazon FBA business or in other words how would you make that amount of money but with no money to start off with, I think that is a better thing to focus on.

  28. Hi there!

    I hope my message finds you well. I’m a little late to the game and just started listening to the audio version of 4 Hour Work week and am embarking on my own single subject case study. I was wondering, have you ever considered running a trial to see what kind of thought processes change the most over the course of people engaging in the 4 Hour Work Week activities? I’m a graduate student in Clinical Psychology (which….is a lot) and I have a natural curiosity about what the mechanisms behind behavior/cognitive change are and if there are specific changes that correlate with success in following your philosophy.

    What do you think the most important changes in perspective that a person who engages with your book can make? Is there any particular quality that you hope people gain from your work?

    I also wanted to say thank you and to express my gratitude for your inspiring work. It offers hope that there are more fulfilling alternatives out there and that is invaluable.
