About me

A small introduction about myself

Davide Marrone

Entrepreneur/CTO from Milan (Italy)

I'm an entrepreneur working on innovative IT projects. I studied Computer Science at the University of Milan, where I bagged a Bachelor of Science and a Master's of Science degrees.
In 2005, during a class of Mobile Computing, I had the idea to send messages like SMS from mobile phones with an internet connection that can run mobile applications, to reduce the cost of the SMS. Today, we all well know WhatsApp but in 2005 it was another world: iPhone, Android and also WhatsApp didn't exist yet and it was the first year (in Italy) that the internet was available on Nokia mobile phones. After having that idea I started a personal project to implement it and in 2007, two years before WhatsApp was launched, I founded my first start-up: Skebby.
Skebby, over the years, has made a big pivot: from the original idea that allows consumers to send SMS from their phones at a lower price compared to mobile operators, it has become an enterprise solution made with an innovative platform allowing businesses to send SMS via internet from their web applications.
Since 2015, I have been the Co-Founder and CTO of Catapush, that is a simple, reliable and scalable delivery API for sending transactional mobile push notifications from websites and applications.

Skills & Expertise

I can say I’m quite good at

Experienced Chief Technology Officer with a demonstrated history of working in the Computer Software industry. Skilled in Enterprise Architecture Design, Microservices, Linux System Administration and Mobile Applications.
I started working in 2000 as a Freelance PHP Developer for small sites created with the LAMP stack. In 2005, I created Skebby from scratch using PHP and J2ME. Skebby was the fastest growing company in Italy in the SMS messaging industry. I was the CTO of a team of 10 people developing with PHP, JavaScript, Java, Android, and iOS.
My knowledge as a Linux System Administrator on the LAMP stack with Java microservices grew massively during the Skebby experience and then with Catapush.
In Catapush I have designed all the microservice architecture based on the AWS ecosystem. At the moment, my main interests are still building innovative solutions on distributed microservice architecture. I really like to work on AWS for all the new and innovative technologies that they provide.

Catapush is a simple, reliable and scalable delivery API for transactional mobile push notifications for websites and applications. Ideal for corporation sending data-driven transaction notifications, including targeted e-commerce and personalized one-to-one messages. With delivery confirmation and real-time status tracking of each message sent, it is possible to build intelligent messaging logic.
As CTO, I have designed all the platform from an architectural point of view. I have created all the server infrastructure with the Salt configuration management software on AWS. The team has grown up to 10 people working on PHP for the frontend, Java for the backend and we have developed also the SDK for all mobile operating systems: Android, iOS, and Windows.

Founder and CEO until July 2008 then CTO and Vice President

Skebby today is an innovative platform for sending SMS messages via internet from business web applications.
I had the idea of Skebby in 2005 while I was at the University. In 2007, I founded the company and started to work on it full time. In 2008, I found two Business Angels that financed the start-up. Together we have created the fastest growing company in the SMS industry in Italy with more than 30.000 business customers.
I was interviewed by my investor for the "Face2Face Capturing Creativity" initiative just after the closing of the deal, the video is available here: Davide Marrone Face2Face. I successfully exited from the company in 2015. Today, Skebby is still one of the leading SMS providers for business customers in Italy.

During the Skebby experience, there was a lot of interest from the media on the start-up, my story was covered in different news about Skebby in national newspapers and also on national televisions. Here are some references:
