The company was founded in 2014 by brothers Greg and Mark Fahey, who developed what they believed to be a world-first portable container-weighing scale.
There was strong demand for its container scales from military customers, with multiple sets of C-Jacks sold to the US Air Force and US Navy last year.
Bison had just completed an order for seven sets to Nato and had large orders pending with other European military customers, Greg Fahey said.
Growth had been fast for a young company and Mr Fahey was ''pretty proud'' of what had been achieved.
A new container lifting solution developed last year was proving popular in export markets.
Bison's first full container load of C-Lifts was shipped to Chile this week and individual units had already been dispatched to Israel, UK, Qatar, Chile and Nigeria this year.
Two new container lift models were being released this month, aimed at building on that early success, Mr Fahey said.
The development of those solutions was driven by wanting to diversify and expand what it was already doing.
It had seen an opportunity in the market and developed a range of new solutions for it, he said.
Major changes to international shipping rules introduced in 2016 meant exporters were required to verify the weight of every container shipped.
That market had softened somewhat this year and Bison had to work hard to discover for opportunities, which it had done, Mr Fahey said.
The military was one with good prospects, as customers liked the robustness and portable nature of the scales.
One of the biggest challenges for the company was connecting to customers, as they tended to be on the other side of the world.
There were now 10.5 full-time staff in Dunedin and a Kiwi, living in Lithuania, who was permanently based in Europe, which had been very useful.
