Mark Goldspink
Chief Executive Officer
After leaving university with a PhD in Chemistry, I was lucky enough to join a large multi-national oil company (Texaco Inc.) who provided a framework in which I was allowed to develop my skills and capabilities in an array of new and exciting roles. In order for me to successfully execute these P&L jobs, I was provided with first class business training and development, for which I am still very grateful.
As well, as the outstanding business training, my background as a research Chemist always afforded me the opportunity to pursue innovative solutions. However, these new innovations have always been practical and provided immediate returns in the pursuit of operational excellence. In a nutshell, I am passionate about streamlining processes in a way to drive greater efficiency. A good example of this is was when I was Retail Director of Texaco In Europe and turned the business around by $100m.
Having spent over 12 years in the oil sector, I moved into payments in 2000. I believe that oil companies really changed the face of the credit card industry, as they took cards many years before the high street retailers. Despite this linkage, moving into the payment sector was a big leap which has been very exciting. No more so than the 5 years I spent at Retail Decisions as Managing Director and then as Vice President for CGI Inc, working on some very large payment outsourcing opportunities.
However in 2013 I was lucky enough to start working with Ashley Head, who is highly recognised in the payment sector, on rejuvenating The ai Corporation (ai). I am really fortunate to work with an outstanding high performing team, who are driven to re-engineer the current fraud and payment processes. Lots to do – very exciting times.

David then joined CGI, project managing the CGI Horizon 3 platform. David then transferred his expertise in software development, project management and operations / infrastructure into a successful IT consulting career in the financial services industry, working with companies like international fuel card services provider, WEX; helping to implement their international fuel card processing platform for Shell. Now, David is the CTO for the company. He is PRINCE2 certified.

Piers Horak
Chief Commercial Officer
I found my way into the exciting world of payments and risk whilst completing my studies in finance. I began my career with Digital Outsource Services as a Fraud Risk Analyst working 24/7 shifts, investigating and making decisions on transactions for some of the largest online gaming Clients in the world. I then went on to Head up the eCommerce and Risk Team responsible for the end-to-end online payment solutions and strategy for existing markets as well as entry into new global markets, I was also responsible for driving the ecommerce fraud and risk strategy and operations.

This included managing teams providing 24/7 Risk Alert management, rules optimisation and strategy, implementation and specialist fraud account and relationship management. After the MasterCard acquisition of Datacash I spearheaded the white labelling of the Datacash solutions so that Acquiring banks could offer their merchants value added end-to-end services as their own. After this I went on to head up Fraud Product and Risk and was responsible for defining the global fraud and risk services strategy and product pipeline.

Nick Walker
Chief Operations Officer
My ‘working life’ began in the Royal Navy where I served on HMS Leander and HMS Ark Royal, working on communication and weapon systems. This gave me a solid grounding in my work ethics that are still with me today; working smart, hard and giving the absolute best I can, while always striving to do better. After the Navy I studied Electronic Engineering, while working for an EPOS developer and manufacturer, I was ‘hands-on’ developing some of the early EFT and POS machines that were deployed to retail fuel stations around the world.
I started out as a ‘techie’, then had a great opportunity to grow and boarded my skills within a business that I helped set up. Establishing and managing various departments from development, project management, customer services, manufacturing, sales and business development; I finally joined the senior management team, taking the business to a full listing on the London Stock Exchange. That experience put me in good stead for my next career step, joining Retail Decisions (ReD), where I was very much involved in developing the business from a UK only, one product business, into a leading global fraud detection, fuel card and payment solution provider. My time at ReD included running various types of operations, covering fraud prevention, payments and fuel cards around the world, including South Africa (my home for many years), China, USA, Australia and LATAM where I worked with some very capable people, some of whom I now work with at ai.
At ai, as COO, I am responsible for all operational departments in the company including fraud & analytics, support and change management by building a best in class operations team.

James Quickfall
Global Accounts Director
I started my career in Customer Services, predominantly in the telco space, running B2B and B2C call centres for O2. This gave me a strong service ethic and an appreciation of the importance of communication with Clients, both written and spoken. In combination with my passion for languages, I have continued to place huge importance on building long-lasting business relationships and how we work together both locally and internationally.
After O2, I managed the European service operation for Psion computers before moving into the dynamic and ever-changing fraud and payments industry in 2002, where I have remained until now. I joined Retail Decisions (ReD), now owned by ACI, in January of that year and held a number of roles including Head of Client Services, Head of Marketing and latterly taking responsibility for the Channel Sales team, working with payment processors, banks, third parties and direct Enterprise Clients.
After 10 years at ReD, I was offered the opportunity to gain some direct banking experience when I joined Elavon, a European acquirer and part of US Bank. There, I ran the 3rd Party Sales channel working with some of the largest Independent Sales Organisations in the UK and abroad.
I joined ai in 2013 in the role of Commercial Director. Here I am responsible for most of ai’s European business and with direct responsibility for several strategic Clients. It is a privilege to work as part of a highly motivated and capable team.
I live in Surrey with my wife and two children, who help me to occupy what I used to call my ‘spare time’.

Ralf Andreas
Head of Security and Architecture
My interest in all things Information Technology related started out as a scholar where I started writing code and upgrading friends PCs to earn some pocket money. To add an academic underpinning to the passion, I went on to obtain a Commerce Degree in Information Technology and Business Administration.
My first formal role was as a Software Engineer at a software start-up in Mannheim, Germany where we developed Distributed Sales Force Automation Solutions. The early 90’s/ pre-internet era were an intense and exciting period and growth in the IT sector was fast paced. As the company grew and expanded into the UK, US and India, my role grew, and I became head of the global Information Technology team.
In the late 90’s SAP acquired the business. I managed the technology merger and then stayed on with SAP for another 2 years before deciding to return to South Africa to head up the Information Technology division for another start-up – this time a Cellular Service Provider in Cape Town.
The early 2000’s saw a monumental growth in mobile technology. My role was to design and implement the information, billing and provisioning systems for a dual network Service Provider. A very intense and exciting period which culminated in a merger of our subscriber base with MTN and Vodacom. Over the next few years, I continued to consult as a solutions architect for several other Service Providers.
In 2003 I joined Retail Decisions SA, a company that specialized in payment fraud prevention solutions. My initial role was as program and technical lead for projects that saw us implement industry wide pre and post auth fraud prevention systems for the South African Banking and Retail community. I remained with Retail Decisions SA in the capacity of General Manager/ Head of Operations until 2016 when the company was acquired and merged into ACI.
I joined AI in 2016 and looked after several key accounts in Africa and the Middle East, before taking on the current role of Head of Security and Architecture.
