John Hansen

John Hansen

CEO & Founder 

John is a visionary thinker and irrepressible optimist with innovation in his DNA. His innate curiosity and enthusiasm for a future shaped by possibilities is the driving force behind his quest to go beyond the limits of current technology and capability.
He is a science graduate with extensive experience in digital electronics, design of microprocessor based telemetry systems, production control systems, and commercial software development, primarily in the field of retail POS systems. He also brings years of commercial experience into the company having been involved in other enterprises prior to WizBang Technologies.
Soon after graduating in physics in 1972, John found himself working for Cutler-Hammer NZ designing microprocessor supervisory, control and data acquisition (SCADA) systems for South Australian Railways and Sydney County Council. 
This experience in the early adoption of a new disruptive digital technology inspired John’s “possibility” mind-set and set him on a trajectory of innovation.
He started his own electronics and software design consultancy and was commissioned to design many industrial and commercial systems. Among these was a microprocessor weighing and production control system for wire manufacturing, a spot welding machine digital controller, a messaging system for large electromagnetic and LED outdoor advertising displays, a numerical machine controller for the manufacture of printed circuit boards, a digital codec for wireless data transmission and radio paging and a vehicle speed detection system.
With this experience behind him, John saw the possibility of developing commercial software with scalable global potential and took the opportunity to work for an enterprising South African company to develop a complete financial and point of sale system for furniture and clothing retailers, known as Furnpac and Ragpac.
Returning to New Zealand in 1987, John co-founded Pacific Business Systems (now Excellent Software and Services) and developed a successful big ticket retail point of sale system known as Retail-Plus and a hire purchase ledger financial control system.
In 1997, John and his family who had all become confirmed café junkies were inspired to find a way to make life easier for waiters. The dream was to create a ground-breaking and innovative new hospitality point of sale system, encompassing wireless hand held technology for taking orders from tables. Wi-Fi was not available for portable devices at the time, so the solution required the design of a plug-in digital wireless transceiver circuit board for the Palm Pilot PDA and a corresponding wireless base station transceiver.
The solution John designed utilised a UHF FM narrow frequency band, with a range of 300 metres. Extremely low power consumption was a design objective with four days battery life being achieved through the use of CMOS technology.  In order to keep hardware production costs down, collision avoidance, radio noise filtering, and error checking and correction were designed into the transceiver software drivers rather than the hardware.
The success and reliability of this mobile solution, known as WizBang Waiter at the time, was the genesis of WizBang Technologies.
Today, John leads WizBang Technologies, with the single-minded purpose of driving innovation and growing global distribution channels.
In his time off, you’ll find John sampling local hospitality with family and friends, keeping fit pounding the streets or swimming at the local beach where he currently lives in Millwater, Auckland. He also somehow finds time to fuel his fascination for science and technology, especially cosmology which seems to resonate with his curiosity about the nature of things. John is also passionate and concerned about environmental issues, food quality, food supply and organics, and thinks the extraordinary movie “Food, Inc” should be mandatory viewing for all!

Richard Crowle

Richard Crowle

Senior Software Developer


Richard is originally from England, growing up in the Norfolk Broads where he spent a lot of his childhood in and on the water doing sailing, kayaking and swimming.  He holds a Master of Electrical and Electronic Engineering from the University of Newcastle upon Tyne, in northern England.  He gained valuable experience in both the retail and hospitality industries during his time studying.

Richard found himself in New Zealand after some extensive travel, during which time he continued to work in hospitality.  It was during his time as a general manager in a busy Auckland Bar/Restaurant that he was introduced to WizBang.  Given his IT skills, he was assigned the role of maintaining and managing WizBang’s onetap POS system, along with the task of implementing onetap's stock control and loyalty/marketing modules for the Bar/Restaurant.  

After 18 months of using WizBang's software as an end user, he jumped at a chance to work for WizBang. He started off in our technical team and in 2010 he moved over to the development side of our business where he worked on a range of products: ROSS, Stock, Reports, integrations and the main onetap program.  The combination of his electronics degree, practical experience in hospitality industry and technical support roles, gives Richard the ability to understand problems and solve them from both the end user/customer side as well as the technical/development side.  To this day, he remains focused on producing a reliable, stable and high quality product.
