We build AI team members for Australian businesses.
Businesses kept asking us to build them an AI tool. What they actually needed was an AI team member that worked inside the tools they already had.
Between AI hype and real operations, there's a gap.
We spent years building software, automation, and AI across financial services, healthcare, construction, and real estate. We saw how much these tools can do when set up properly, and how much gets wasted when they aren't.
Most businesses don't need another subscription or a 60-page strategy deck. They need a team member that does the work. So we sit down, understand how they operate, and build a custom agent that slots into the tools they already use.
We build it, host it and run it. Your agent stays sharp because we're the team looking after it every month, not because you learned a new system.
AI bolted onto broken processes makes a bigger mess, faster. So we diagnose first. Then build. Then operate.
Charles McCahon
Founder & Lead Developer · Brisbane
Charles has spent years building software and AI inside startups, taking ideas from a whiteboard through to products people actually use. He started Synexa to bring that to businesses that know AI matters but can't see where it fits.
His real strength is translation. He's as comfortable in the code as he is across the table from an owner who's never written a line of it, so he can quickly spot where AI genuinely earns its keep, and where it doesn't. No jargon, no tools you'll never touch, no money burned over-engineering a problem you didn't have.
It's work he's genuinely into. Understand how a business actually runs, get the foundations right, then build AI that does real work and keeps doing it.
What we stand for
Not corporate buzzwords. The actual rules we run the business by.
Plain English Over Jargon
We explain every build in language a non-technical owner understands. You'll always know what we're doing and why.
Outcomes Over Outputs
We measure success by hours saved, costs cut, and revenue added. Not by how many tools we installed.
Partnership Over Projects
We're not a set-and-forget agency. We build long-term relationships and grow alongside your business.
Foundations Before Agents
We diagnose before we build. If the processes aren't ready, we fix those first. AI bolted onto a mess just makes a bigger mess.
Proudly Brisbane
Based in Fortitude Valley. We work with clients across Australia, but being local matters. Face to face. Same room. Real trust.
Let's build the agent your business needs.
No pitch, no pressure. Just an honest read of where AI fits.
