About Us

Who is a DataSpartan?

Every member of the team is educated to Masters, PhD, or above.  We are exposed to a wide variety of clients, projects, tools and solutions. We are motivated by the difficulty of the challenge and the desire to be at the spear-point of an exploding industry of software, science and new knowledge. We source our talent from the world’s leading research and academic institutions. Every Data Spartan is treated equally, has direct input into the business and is supported with the opportunity to work, study, create new products or enterprises within our ecosystem.

How We Work

The experience, education and motivation of our team ensures we deliver every time we are engaged.

DataSpartan’s capabilities are not defined by the technology stacks we use, but by our team’s imagination and ability to creatively solve impossible problems.

We are truly agnostic on the tools we utilise to achieve results. As experts in our craft, we simply pick the best systems for the job in hand, or adapt to the tools our clients present us with. Every member of the team is fluent in multiple software languages and methodologies with experts available on hand for any major data, architecture and ML and AI systems.
