The NineHertz successfully built a social media app for advertising as specified and met all our expectations. Their meticulous, accommodating, and cooperative approach ensured a seamless partnership. In addition to their excellent project management, they also have exceptionally strong technical proficiency.

Jimmy's Review Sourced from Google
Shaun, Dave and the team at Launchlab took my startup from idea to product launch. To say i am a massive promoter of these guys is an understatement. The level of diligence, responsiveness, thoroughness and capability far exceeded any expectations i had for a software development project. The team, led by Shaun, made this experience very simple for me. They were flexible and were always conscious to make sure the key decisions along the way, aligned with my vision. These guys should be every Australian entrepreneurs software developer of choice!

Working with Shaun and Dave from Launch Lab on OX Rooms has been a fantastic experience! Choosing them to develop our platform and website was one of our best early decisions. After meeting with several development teams, it was clear that Launch Lab not only understood our vision but could also deliver a top-quality product.Launch Lab consistently delivers high-quality work and is responsive to any issues that arise. They communicate directly and don’t waste time, keeping the scope on track while remaining flexible with adjustments and always bringing solutions—not problems—when challenges come up.Shaun and Dave have been invaluable partners, making it enjoyable and rewarding to work together on OX Rooms. I look forward to our ongoing collaboration and reaching new heights together!I highly recommend Launch Lab to anyone looking for a skilled and reliable development team!

Russ Watts's Review Sourced from Google
I've just completed a project with Launch Lab and it's the second time I've worked with them on launching a website (for two different companies, APositive and Waddle). I can't praise them highly enough. When I got the opportunity to build a new website, my first thought was 'speak to Shaun'. They know exactly what they are doing, I trust their recommendations completely and their work is of the highest quality. From beginning to end everything has gone smoothy and professionally. Highly recommend!
