    John, Excited to be following your blog. I took a few classes with you and you have been a great help in finding direction. One thing though, why does the Rincon logo look like a left when Rincon is clearly a right!

  2. john greathouse

    You are very observant, but not the first person to point out this flaw in our logo!! As I am an enthusiastic but nearly inept surfer, you’ll have to excuse this error.

    john I would like to have help opening a bakery in the future. id like you to be my mentor

  4. John Greathouse

    Amber – that is very kind, but you are far better off finding someone local, who has experience running a bakery. Best of luck to you.

  6. Domenick Scherpf

    Good Afternoon John,

    My name is Domenick Scherpf, Co-Founder of VigorWay; a social platform for the active lifestyle. My partner and I will be in Santa Barbara this weekend into next week and are really interested in sharing our vision with you.

    VigorWay is available on iOS and Android. If you have an email I can reach you at, I would really like to go more into detail.

    Thank You,
    Domenick Scherpf

  7. John Greathouse

    Thanks for reaching out Domenick, but VigorWay isn’t a good fit for Rincon. We generally only invest in B-to-B SaaS and AdTech. Consumer-facing businesses are not our forte. Best of luck to you.

  8. Domenick Scherpf

    John, thank you for the quick response. Best of luck with you also.

  10. Cosi Productions

    Hi John,
    Firstly thank you for the blog and info you have posted over the last few years. I have learnt a tremendous amount which inspired me to start my own company which I would like to tell you about.
    My name is Joshua Blitz and I am founder if Cosi. The focus of the company is on branded IP apps.

    What makes Cosi unique is that we have signed up the IP rights of the biggest household names worldwide and are developing apps leveraging brand association. Currently we have signed Pele, Muhammad Ali and Bob Marley with more to follow.

    We have released a soft launch of our first title Pele: King of Football and the quality of work speaks for itself. The game was featured by Apple as Best New Game in 162 countries upon release resulting in 850k installs with an average 4 star rating across around 3000 reviews over iOS and Android.
    Brand association is key in our model. We were able to secure T-Mobile as our sponsor for the USA version of the game.

    As you can see in the Pele title, its more than just a game. We are offering users the chance to interact with the legend like never before through exclusively produced interviews unlocked through gameplay and the chance to win Real World Prizes. These include signed Pele shirts, balls and even the chance to meet Pele in person.
    We also just signed a deal with a pro team in the UK in which we will offer 5 lucky winners the chance to try out for a pro contract with the team. Something has never been done and will be picked up big within the UK press.

    Our goal is to create top content, building a one on one relationship with the consumer enabling us to monetize in different ways. We have a plan in place for Ali and are looking for the right partner to help us take this to the top.

    We also recently signed a deal with a large company in China, SkyMobi, who will publish the game in the region and have guaranteed 5m users. Other publishers want the game as they are in desperate need of high end branded content.

    It would be great to tell you a some more info and send through our deck. My direct email is

    I appreciate that your time is sensitive and any feedback is welcome.

    Please see the Pele game link below.

    Josh – congrats with Cosi. Unfortunately, you are operating in a space I know nothing about, so my ability to help is extremely limited.

    Best of luck to you and your team.

    The Elegance and Impressive House Design

    This house is really elegance and impressive with its outdoor design with delightful
    pool, leading to furniture shop in Cambodia construction materials stated.

    According to the architects, “the design needed to express the transition from commercial strip to small scale residential neighborhood, so the scale and detail respond to
    both conditions.

    Construction is simple cubic stucco forms, with exposed wood structure, and softened with landscaping”.

    Furthermore, the indoor-outdoor connection was achieved by opening up the social areas at the bottom level towards the garden and swimming pool.

    “The master suite is located in the rear, with its own courtyard, and has a bathroom that enjoys large glass doors to the pool and a shower that connects directly, allowing a
    convenient way to shower after swimming. The upstairs area is devoted to flexible bedroom, office and studio space”.

    Hello John – I read one of your articles on Forbes talking about how the MBA degree holders may not be a good fit in startups. What are your thoughts on MBA innovation? Specifically, do you feel that the MBA can be gamified?

  14. John Greathouse

    Arun – I have no idea. However, given that “gamification” is a bit of a well-worn term, I am a cynic. Happy to hear what you have in mind. My email address can be found here:

  15. Zachary

    Hey John. Read a recent post on Forbes. I have a Google Alert set up for ‘growth hacking’ and your post was the only one Google found on November 30th. Keep up the great work!
