The serial entrepreneur is still in Canberra doing the only thing he knows how - running a tech start-up out of a first-floor office in Phillip.

Bullock sold his online transaction company eWay to American payment technology services giant Global Payments in early 2016. And now he's hoping to do it all again.

This time, Bullock is capitalising on research that humans are naturally competitive creatures by gamifying the workplace - whether that's a real estate agency or a call centre.

His new start-up, Spinify, is all about "lively leaderboards", where a team of colleagues competes against each other to meet and exceed individual and organisation-wide KPIs.

Think the leaderboards from your favourite childhood video game - Mario Kart or Formula One racing - but with a much more corporate feel.

"People are absolutely competitive," Bullock said.

"It's in our nature - we want to beat people. It's a culture thing.

"So with Spinify, you bring all of your sales data and KPIs - whether that's emails sent or cases closed - to life with big televisions in the office showing bright, bold leaderboards."

Walk into the Ray White Real Estate office in Belconnen and you'll see Spinify in action. The real estate franchise has leaderboards across three televisions in the office, pitting sales agents against each other for number of deals completed each month.

While Spinify displays best on huge smart televisions around the office, a mobile app alerts users when they've hit a major achievement, which can be marked by a personalised video message from the CEO or a crazy celebration clip from YouTube.

"It's about making data fun, it's not meant to be crazy serious," Bullock said.

"The whole concept is, forget the people at the top, because the they're just going to do what they do and they're just freaks.

"With people at the bottom, you either want to move them to the middle or get them out because they're either in the wrong job.

"We target those people in the middle, because if you can move the middle by 5 per cent you change the whole company, and it's crazy revenue."

Globally, Spinify has customers in Spain, the UK, South Africa and the US, and the start-up's revenue is doubling month-to-month.

Bullock flew to San Francisco last weekend to push Spinify to a crowd of 170,000 people obsessed with customer relationship management (CRM) tool Salesforce. Spinify integrates with Salesforce, the CRM tool Bullock was using to manage customers at eWay and which inspired the idea for Spinify.

"I had 80 staff at eWay and I had 72 TVs and I used those TVs a lot to visualise our sales," he said.

"But I was also limited what they could do, which is why I built Spinify."

Bullock graduated with a degree in computer science from Wollongong University in 1994 and worked in various programming and multimedia roles for Westpac, Smith's Crisps and Optus before moving to Canberra to become the web master at ATSIC. He worked at ATSIC for six years before his "side project" eWay became too big to ignore.

There were more than a few lessons learned in the 14 years he spent building eWay to a company processing one in every four online payments in Australia and $6 billion globally every day.

"I've learnt all these stupid things I did with eWay 20 years ago - like just focusing on Australia initially and coding everything ourselves - and I'm doing the opposite," he said.

"The biggest thing though is having a minimal team on the ground in Canberra and using a virtual team via Upwork to deliver pretty much everything.

"I'd love to build another eWay - what I liked about eWay was that every month three million people got something because we got out of bed, and that felt pretty good."
