Get to know Zacc, our CEO and co-founder
What was your background before eSIM Go?
I’ve spent most of my career in wholesale telecoms, first with Vodafone and then with a number of signalling solution vendors, telco carriers and service providers. These were primarily new business development roles in the telecoms wholesale, interconnect, MVNO and CPaaS space, where I was exposed to a variety of commercial opportunities in the market around new technologies, and how these enable new business and revenue models.
In 2016 I set up TDZ, which evolved into Epik8 in 2019, to help scale-up technology businesses expand their sales in new markets. Epik8 has proven very successful and grown rapidly despite the turbulence of the pandemic.
When did you first discover eSIM?
It would have been 2016 at the MVNO World Congress in Amsterdam. The brand new GSMA standards for eSIM had just been published for the first time and both OEMs and telcos were showing a great deal of interest. It was clear that this was going to revolutionise the telecoms industry, it was just a matter of how quickly adoption would reach critical mass.
What's your role at eSIM Go?
A bit of everything. I co-founded the business but have a more commercial than technical outlook. So it’s mainly steering our vision, as well as leading on brand, marketing and finance.
How would you describe the culture of the company?
Exciting, disruptive and positive. Innovation brings change, and while many people say that they like change the reality is often quite disorientating. So our culture is very good at enjoying the unpredictability of disruption, and bringing order to it by enabling our customers to create what they need to drive their chosen eSIM business model.
Where do you see yourself and eSIM Go five years from now?
I expect eSIM Go to be working closely with most of the top airline carriers and OTAs, as well as in other travel and sector categories. In less than 5 years, eSIM will be the dominant way of consuming mobile services with billions of individuals looking for eSIM deals. 5G will also be ubiquitous, pushing up the demand for data consumption. There'll be more technological innovation for sure, but also a continuing evolution of commercial business and revenue models. eSIM Go will remain at the forefront of this.
What do you do to unwind?
It won’t surprise you to hear that my life is quite dull outside of work… two young kids and running multiple businesses for 4 years doesn’t leave much room for hobbies! But I like to spend my free time by the sea with my family and my dog.
As I drop other work commitments to focus 100% on eSIM Go, I forecast more free time opening up (hopefully), so I plan to get back into running and fitness. Then I can tick completing an ‘IronMan’ off my bucket list!
