Mark Cuban - Shark Tank

Billionaire Shark Tank Investor - List of Shark Tank Investments

Yes Mark Cuban is married
Mark Cuban and Wife Tiffany Stewart
 Mark Cuban happens to be someone I've followed all the way back into the late 90's when he sold to for a whopping $5.9 Billion in Yahoo stock. Marks timing was at the height of the dot-com boom and just before the dot-com bust. At the time, had revenues of approx. $60 Million a year that Yahoo paid roughly 100 times revenue and set-up Mark Cuban for life.

From this investment and several other very good investments to follow, Mark Cuban's net worth ranked him #459 on the list of the "Worlds Richest People" in 2011. With $2.3 Billion Dollars in assets, what's a guy to do with a few billion dollar payday? If you're Mark Cuban, you go shopping for a $40 million Gulf-stream V jet and set a Guinness Book of Records with the "largest single e-commerce transaction" over the Internet.

Mark Cuban Buys The Dallas Mavericks

In early January of 2000, Cuban takes some of that "funny money" paid from stock and buys a stable business and majority stake in the Dallas Mavericks for $285 million. Mark never having any intentions of becoming a passive Owner of an NBA Team, has been an active participant on the sidelines from day one. If you have ever watched the Dallas Mavericks games over the past decade, sometimes it's hard to tell if Mark Cuban is a basketball player out of uniform and not the owner of the team. He has so far amassed as close as I know, somewhere around& $2 million in fines imposed by the NBA. Mark openly wears his passion for the game on his shoulders much the same way he conducts business on the National Hit T.V. Show "The Shark Tank."

Mark Cubans Reality T.V. Show

In February 2004, Cuban started his own reality t.v. Show called The Benefactor. The Show was a six-episode series involving 16 contestants trying to win $1 million cash. Around the same, time a few other Billionaires Donald Trump and Richard Branson also came out with their Reality Shows. Personally, I liked all three and wished Mark would have stayed around for a few more seasons.
True to Mr. Trump's personality, and all these years later, he is still fighting with Mark on Twitter on what seems like a regular basis. Trump just cut down The Shark Tank Show for being pushed back to 9 p.m. on Friday nights. This latest Twitter punch was a few days after Shark Tank broke its records and had the highest ratings the Show has ever had. Looks like Trump got Trumped on that one, again. Apparently, The Donald is starting to get a little worried that Mark Cuban and the Shark Tank Show is getting the last laugh in this decade-old feud.

    Total: Mark Cuban invested in 18 new products throughout the entire Shark Tank Season 4 Episodes.

    Added note on Season 4. I have always been impressed with Mark Cuban but even more so in how he has handled himself this season. You could walk in there selling toothpicks and still have a chance to make a deal. Not because of the product itself but because of your attitude and determination to succeed. Remember Steve that draws cats for a living? "Failure is NOT an Option." It's a trait that each and every contestant listed above clearly has demonstrated.

     Mark Cuban invests in People and seems to put the money part way down on his list of potential investment decisions.

    5. Hello Mr. Cuban,

      My name is Mark also and I live in Pittsburgh, Pa. I am not real good at this computer stuff so I hope you get this. I have an idea for two items, one is for canine training and the other for children's potty training. Yeah you read right. I trained dogs for 15 years and my kids for 20. Kids and dogs are similar, kids just less fur. To the point. I don't know where to start or how much money I will need. They are just in my head for now. I don't know who to trust either. So what the hell, it doesn't hurt to ask. If you do recieve this and if you are so inclined? My e-mail is and my cell is 412-480-2815. You can call any time. I fell off a ladder and broke my wrist. So I am out of work for a while. Thank you for your time.............Respectfully Mark DiCocco

      I have an idea but need help with making it happen. I have had over 13 surgeries and have been in the hospital over 30 times in the last 5 yrs. I would like to make a device that would allow all hospital and doctors to view your medical records at once. I get sent to many different doctors and they all want records. It runs me hundreds of dollars to do so. I would like to have a chip that has everything in it with my medical history that could be updated by each doctor or hospital visit. Something that is water proof and that can be worn on a wrist or necklace. I believe this can be done. Please help.

    13. If you like Basketball this is for you. The “Perfect Arc” is a Basketball training aid that develops the athlete’s shooting ability. After practicing with this device the players develop a
      natural arc on the ball which results in less blocked shots and better shooting
      percentage. How many times have you heard a coach yell “Put more arc on the ball.”
      This device will train the players to shoot naturally and put the proper arc on the shot.
      It helps develop muscle memory when the guard is removed for continued shooting improvement.
      This training aid can be used at all levels of participation.
      It can be installed in just a matter of minutes and can be easily stored.
      The product is made with poly-carbonate a material that will last for many years.
      This product has a patent pending.
      There is not another product that compares with “The Perfect Arc” and this product has proven results. You can expect to improve field goal and free throw percentage by 12 to 15%. This is a statistic everyone would love to accomplish. Please partner with me and we can make this product a tremendous success. E-mail

      What i have to offer you, will be one of the greatest investment known to history, get ahold of me at, thank you. Hope to talk soon.

    15. DEAR MR. CUBAN,

      I am a Special Education Teacher, however, 13 years ago, a student accidently, pulled my chair and I broke my neck. I have dealt and I am still dealing with a political unjust system with the California Worker's Compensation System...No worries not writing you for you to solve the system, a few prayers... I will take if you would pray.

      I am writing cause weekly I watch your show, and I grow weekly as an Educator, as a human being. and as a long ago Entrepreneur. Thirty years ago I was awarded Entrepreneur award from President Roosevelt's Son James through my University: Chapman University in Orange, CA.

      Some day with a more lessons to retrain my brain from hitting my head I will write my story and I know my story will touch many and help people, especially, struggling individuals with disabilities. Until then I keep the fires going for my future with real souls that touch my life. You are one of the souls...The love you have for your Son, for your family, for your players, for your business is beyond words....

      Honestly, at first I watched the show.. one: to recapture that drive I have in me that got me the award in the first place, then secondly, because I have a great friend, that used to be my doctor. I ran his support group in Beverly Hills for Chronic Pain and for his patients with an awful illness RSD> which I will make a film about individuals cursed with this evil illness. (My film professor told me Meg, no a student will not do this film you have come up with an idea for, you will, and you will make it cart blanche at Chapman...even if it takes you ten years to get out of workers comp you will make this film...(NEXT YEAR will be ten years) This doctor, has your spirit, and looks like you somewhat. I was intrigued how you two reminded me of each other, so honestly, began watching the show only because of this! I did not know who you were, nor did I know the other sharks.

      Every week I tell myself write, and I answer myself, "Meg you cannot write worth beans..." However, today watching the Christmas Tree segment on Rent A Tree, not only did you bring tears to my heart you gave me the determination to write you regardless, of disabilities. I knew I had to write you...( A Secret, I was injured badly, but I have always been an Irish Story even if I did not hit my head I would have probably not gotten to the point even if I did not hit my head.)

      You see with a business eye, but never seem to forget to look in the souls ..especially if their business will help humanity.

      Dr Lawrence Ross Miller is my dear friend, he is married to a Cedars DR. Azita Far they are both pain Management Docs... and they have twin toddlers, and Larry has two grown boys by his first marriage.

      Thank you for reminding me of his driven spirit as a doctor, the resemblance was intriguing, and the year plus I have watched your show, I have grown and learned several business ways and life lessons you all have taught me, and from your belief in human kindness.

      Thank you,
      I pray your Son's skin condition is better.
      Margaret Jeanne "MEG" Murray

    16. Dear Mr. Cuban,

      Back to school means back to germs. My product is the Coughy Cup. It's nothing more than a paper coffee cup with a plastic lid and a filter. The Coughy Cup captures, contains, filters and kills 99.9% of germs & viruses. This means the germs and viruses stay in the cup and not in the air, on your hands, body or others. The technology is simple. We use the same face mask filters used by doctors during surgery along with an antiviral. Simple yet so very effective. Pass the Cup, Not the Germs. Not Sharing is Caring.

    17. Dear Mark Cuban,

      I am a freshman in college majoring in Business Administration. I am enrolled in a Management course that I have to present my personal business idea in. I have created an idea/product that will revolutionize the sports fan experience while attending a sporting event/game. I know that you are the right person to contact because of the background that you entail. This idea/product can be created and start to be a success in a matter of minutes if you agree to be the first to introduce it into the NBA with the Dallas Mavericks and then move it around to all stadiums for every sport because it is that demanding. This product revolutionizes the supply and demand factor for a sports fan. If you would like to learn more about this idea/product please contact me at

      All you people looking for a hand out make Americans look bad. Go get a job and work hard and it will pay off. Im 21 and know that. Mr Cuban didn't get where he is today by looking for a hand out. He worked hard

      1. Anonymous5:49 PM

        To you sir, i say kudos,great observation, the handout as you so much say,let me ask, are you self employed now? if so i commend you, i too am selfemployed, however the savvy that it takes to get his dream off the ground is not in my fortay. So, my best play is to speak with someone who will atleast hear me out and tell me if i have a shot at something greater.

    19. Dear Mark, I have heard you talk about your son's eczema and want to share with you about our daughter'recovery. Now age 16, when she was 11, we took our daughter to National Jewish Medical Center in Denver for what has proven to be the only successful treatment for her severe eczema. She suffered for 11 years, from birth to age 11. Her hands and feet would crack and bleed and she was always scratching. Today, she is a happy, healthy teenager . I hope you get this and if your son is still suffering, I urge you to look into National Jewish. Also, there is a summercamp called Camp Discover in Minnesota for kids with skin disorders. It is funded by the American Dermatologic Association. Our daughter has attended for several years. Camp has proven to be a huge part of her healing process. I wish a healthy and happy life to your son, Jake.

      Greetings Mr. Cuban, I along with several others are here presenting our thoughts in some cases our investments,in most our dreams of being an entrepreneur. We see you on television,we see you in the stands,we love the life and the business you uphold and represent, Freedom by hardwood,Hardwork by choice,cause to retire and live on beaches and the like could have been your choice,but you wanted better. This is always commendable. So with out further ado, I too type here,not knowing if it will reach you desk,email or even an affiliate of yours. Well's here to hoping \-/ (cheers). I wish to present to you an idea which I think it's the wave of the future, I do not have a patent just a dream that could probably by crushed nonetheless,, an ambition that needs to be heard. I was watching this motivation video someone posted in Facebook, it stated that most people will die with ideas to make money keep to themselves. I atleast want to know I tried, I expressed, I told someone and why not someone who embraces the entrepreneur spirit, and that continuing drive to succeed. Ok, enough of that,I told you how great I think you are, Please, a second, a day, a month...God forbid a year. I would love to receive an email for you. So , I can set up a call. I would love to present my idea. I don't know if you read this blog,so I'll try another method to contact you as well.Be Blessed. DP

    22. Mr Cuban
      Please take a minute to review the following self funded venture that can be a technology that can be beneficial to the hotel, rental condo's, residence, buildings, airline, train, endless business. My company is Pest Eradication Technology (PET) has applied and been granted qty 2 patents for a chemical free way to eradicate most all insects.
      PET has self funded our own research and have received the patents, identify the necessary technologies to build a working prototype, worked closely with established patent attorney and have identified contract manufacturers and this has all occurred over the last 4 years. We are seeking a strategic partner for us to develop the prototype and test the efficacy of our product.
      Pest Eradication Technologies (PET) is developing a set of technologies which will allow for a device to kills pests without detrimentally affecting the surrounding environment, requires little training or advanced skills from the operator, and requires minimal time to operate. The goal of this technology build a prototype and to address the pest control markets’ need for an intermediate and low impact solution. We could license the technology after we build the prototype and show that it is safe and environmentally friendly. PET seeks equity investment by an investor to share the costs for development and demonstration of a prototype device that can be used to kill insects such as bedbugs and cockroaches, doing so using patented technology expressed in U.S. Patent #7,626,187.
      While this wide range in means of insect eradication is protected by the patent, PET has studied and performed research and development that is now directed toward use of ultrasonic energy applied from an emitter that causes insect to resonate and collapse in presence of high frequency acoustics. A similar frequency could be applied to destroy insect eggs. PET now wants to design, fabricate, test, and evaluate a prototype device that is optimized for target insect eradication using an ultrasonic emitter. Looking forward to hearing from you. John

      Wow, really so many people are actually pitching to Mark Cuban on this blog? What do these hopeless people think? Mark will read these comments section and give them a call. There are certainly better (and closed) ways to reach out to him (facebook, twitter), than to put your business idea (if it has any merit whatsoever) on the comments section here!!

      1. Who are you to be judge and jury. You don't know where Mark Cuban is looking and not looking; ask Matt Damon's wife. Mind your business.

      2. Anonymous12:39 PM

        anything that is legitimately associated with cuban would be a better way to pitch to him. id guarantee he has better things to do than to be looking at his blog.

      Hello my name is warren nelson I love the show but I understand these are hard times and I understand because I'm in the air force and they don't pay that well. But ppl come on. I'm sure more than half the ppl on here have probably not went to the banks first and majority of you probably are not trying to do everything you can before asking a billionaire. First thing before going to someone as a last resort do everything possible and even after you fail you keep trying. Because someone will notice you trying first before not doing anything at all and then asking a billion. Yes everybody wants to be rich.but most of the time you work for it first.

    26. Mr. Cuban, I know you are a car guy!....We just completed a 6 minute demo reel of some of my work (see attached a low resolution mobile version). Please download a HD version at Vimeo Working with several large corporations as well as being the persona for Advance Auto Parts affords me the opportunity to bring many vendors on board. I am respectfully requesting your consideration on any future projects. I have several ideas I would like to discuss with you. Thank you for your time and consideration.
