The 'Where' Team

Robert Volkwyn

Robert Volkwyn

Director Strategy, British Columbia

Robert’s motto is “aut viam inveniam aut faciam”, translated means “I will either find a way, or make one.”

Robert founded Carto World in 1997. At his core Robert is a skunkworks specialist and thrives on solving complex problems. His love for geography and; software innovation has been the driving force behind two internationally successful geo-spatial software products.

Robert has an MBA, is a Chartered Engineer with the UK Engineering Council and holds a Chartered IT Professional grade with the BCS – The Chartered Institute for IT. With over 25 years business experience, he intimately understands how to translate a strategic value proposition into superior decision support, effective operational processes and aligned change initiatives for increased revenue generation. In 2016, Robert published a book entitled ‘The Strategic Value of Data’, which examines the strategic role of information in the organisation and how data warehousing and spatially enabled systems add value. His insatiable curiosity has taken him down, metaphorically speaking, many paths, studying diverse subjects such as business and self-esteem coaching, homeopathic modalities, nutrition and alternative energy medicine. He is a licensed facilitator of The The Change Journey; and Neethling Brain Profiling which quantifies left vs right brain thinking preferences.

He hails from Johannesburg and now lives in British Columbia with his wife and family.


David Boltman

David Boltman

Director Development, Johannesburg

Dave subscribes to quality. If a human being could be certified ISO 9000, then Dave could add that to his resume.

Dave qualified as a Electrical Engineer in 1991, and his love for programming motivated his further studies in Data MetricsHe is an advanced programmer,  initially programming motherboard chips directly in assembler code. In 1997 he joined Carto World and loyal served the team as the core developer for its popular geo-mapping suite of products. His attention to quality and detail was appreciated by users all over the world. More recently Dave has been working with his long time friend and Carto World colleague Robert developing land information systems for municipalities. 

Dave has the privilege of daily working with Chantell his wife. A great team down in sunny Johannesburg.


Colby Coombs

Advisor and Mentor

Colby is our in-house sceptic. More out of dissatisfaction with the status quo than from a compulsion to be difficult, Colby is a contrarian, having learned the value of the maxim, “If everybody is thinking alike, then someone is not thinking”. That learning was gleaned less from academe (Georgetown University, 1965) than from a variety of jobs, starting as a lowly cadet in artillery, where he once sited a howitzer-battery exactly 180 degrees out: “We aspire to be precisely right, but it is better to be roughly right than to be precisely wrong”. After a further period in several U.S. governmental services, Colby worked mainly as an independent contractor, specialising in market-development for financial organisations. He has been resident in five countries, on as many continents. No expertise in geography led Colby to us (witness his spacial acumen in artillery); rather a decades-long association with Robert in South Africa on the perennial problem of transmuting disparate data into actionable intelligence. That work – of collation, classification, clarification and eventual deep analysis and sceptical assessment – is Colby’s idee fixe. It has emboldened him to join this thoughtful journey.

A U.S. citizen, Colby lives on the moors of North East England, in County Durham.

His career has embraced software development, IT architecture, information systems management, geomatics, land surveying, and GIS systems. Furthermore, his travels have led him to various assignments in France, Canada, Chad and South Africa, where he met Robert in 2004. Together they collaborated building Carto World’s EIS system.

How we Work

An Agile Adaption

Highest Priority

Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.


Welcome Change

Welcome changing requirements, even late in development. Agile processes harness change for  the customer’s competitive advantage.



At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.



Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.


Continuous attention to technical excellence and good design enhances agility.


Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.


Simplicity–the art of maximizing the amount of work not done–is essential.


Working software is the primary measure of progress.


The best architectures, requirements, and designs emerge from self-organizing teams.



The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.


Business people and developers must work together daily throughout the project.

Frequent Delivery

Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
