Operating out of co-working hub Spacecubed's Level 9 offices, appbot, and its five staff, are the local tech scene's quiet achievers. 
With their app store aggregrate tool, co-founders Claire McGregor and Stuart Hall have signed some of the world's biggest companies, names such as Uber, Dropbox, Disney and TimeWarner. 
"It's been a lot of work, developing these leads," Ms McGregor said. "We had a database of all the users using the tool (when it was free) and worked from there. 
"That's been my job (since I joined the company), finding good leads." 
The technology, the brainchild of Mr Hall, has developed over the past 18 months. It aggregates reviews of a company's app into a simple-to-use program. 
It makes money through a monthly subscription, $49 to $299, depending on the size - with corporations paying more - and has enabled the team to pay themselves a "decent" wage. Mr Hall said the team would look to expand "by one or two" over the next 12 months. 
 Rest Alert 
Rest Alert founder Felicity Millman has certainly timed her run right. The psychologist-turned entrepreneur is focused on the health monitoring market, one of the hot sectors to come out of this year's consumer electronics show in Las Vegas.
More specifically, Ms Millman's area is fatigue monitoring, or, in layman's terms: a system to stop people dying from accidents.
Using wearable technology such as a Fit Bit, she has created a notification system to let users know about various health warnings, and to enable employers to monitor them. 
It has been embraced by logistics community, including 30 drivers and management at Sadleirs, with another "three or four" businesses - including one of Australia's biggest transport firms - on the books to sign this year. 
Ms Millman, who has been helped by various accelerator programs across Perth, has described the process as "a rollercoaster". 
"There are times when I think, oh my god, what have I done," the 32-year-old said. "And I can tell you I earn a lot less as a start-up founder than working as a private psychologist. And at times it's scary.
"But in essence I want to improve people's lives and do something meaningful, and I feel like I'm doing that."
 Pay Tradie  
For Pay Tradie founder Brendon Ross, the inspiration for his business would become his financial saviour. The former South African, who is developing the invoicing and payments mobile solution for tradies and small businesses, said the eureka moment came after a friendly dinner with the owner of a local solar panel company, who would later become a shareholder. 
"They were saying that cashflow was a real problem, particularly with the lack of up-front payment in the trades area, and he was asking me whether I could build a website with a credit payment element," Mr Ross said. "But I thought this could actually have a mobile solution." 
The web developer, who was working with WesTrac at the time, quit his job to start the company.
After a six-month build, it launched in   September. And although Mr Ross admitted its customer build had been "a little slow" over the past few months because of the festive period, he hoped to ramp up this year. 
There are competitors, but Mr Ross said he was trying to leverage off their WA ownership and word-of-mouth through Perth's tradesmen. He would then look to the east coast. 
 ScanCam 
ScanCam deals with one of the more basic theft issues in WA: drive-off fuel theft. 
The idea came after co-founder Eoin Byrne had a chance encounter with a service station attendant. 
"I pulled into a servo and there was a guy frantically scribbling things down on a piece of paper," Mr Byrne said. "He was writing every licence plate down by hand. If the person looked suspicious, there are 400 licence plates on an Excel spreadsheet which he had to look at for a match. I thought, there's got to be a better way to do it."
Mr Byrne and his business partner Anthony Schmidt, who were both involved in the delivery of ID scanning equipment for pubs in Perth, started working on the idea, which is almost at full commercialisation. 
Their technology, which won a 2015 WA Innovator of the Year award, captures licence plate numbers in real time, logs them into a database and matches them with licence plates which may have been involved in previous fuel thefts. 
"If a drive off does occur, it logs in the iPad, and a client portal where they can confirm and verify the reports," he said. 
The company, which raised $500,000 last year, is in discussion with Tesco in Britain and is looking into debt recovery and licence plate loyalty elements. 
 TeamAhoy  
For Damian Bramanis, the idea for project management software start-up TeamAhoy came during one of those "what am I doing?" moments in life. 
"I was visiting a sick friend in hospital," Mr Bramanis said. "It was a real wake-up call for me when I realised I wasn't even listening to what she was saying. Instead, my mind was back at the office, with all the problems at work. At the time, I was managing a team of 18 people and constantly felt like things might go wrong or that I was missing something important.
"I felt that this wasn't right; that life was too short to be miserable at work."
From there he went about building TeamAhoy. The system aims to gives managers the ability to check-in with their team and get updates their progress. 
After graduating from the Amocm Upstart program, the company has opened the platform to the public and is looking at expanding into the US.
