Tuck In

Joshua Raphael might be a civil engineer by training and trade, but his profession belies his passion and aptitude for spotting a business opportunity.

His declaration as a 10-year-old that he wanted to be an inventor foretold an entrepreneurship career that has included selling chickens, setting up an online portal for chefs and food lovers and co-founding a cryptocurrency mining business.

All of which prepared him for Parket, the business he founded and now serves as CTO. As a Smart City IoT technology, Parket is laying the foundations for smart mobility in South Africa by using technology to solve parking headaches for landlords and motorists alike.

About This Recipe


Everybody loves an app, right? That might be true, but not every problem or product needs one. Instead, Joshua Raphael, founder and CTO of Parket, points entrepreneurs towards responsive websites and the beauty, simplicity and functionality of web apps.

He explains the incremental process he followed to develop, code and refine Parket, and shares how the theft of his newly installed power solution was the impetus for the licence plate reader that became the backbone of Parket’s offering.

Joshua emphasises the importance of knowing when to say “no” (even to one’s girlfriend), unpacks his understanding of product-market fit and discusses how he recruits, retains and incentives his team.

What You'll Learn


Apps are a feature of our times, and this recipe shows that there is more than one way to think about and develop them.

There are insights around how to go about building a minimum viable product (MVP), why it is not necessary to throw vast amounts of money at testing a concept, and how to gauge product-market fit.

You will furthermore learn about the importance of allowing the market to shape your product, and the advantages of web apps over mobile ones.


Learn from someone who speaks from a position of real authority, perspective and experience.


Implement practical tips and techniques learned in the trenches - doing, rather than talking.


Join a cohort of like-minded entrepreneurs in our growing community and share your learnings as you go.
