    The team

    Founder-led. Engineer-built.

    PlatformOne was founded in Brisbane in 2023 by Jack Pate and Lachlan Kosanic, and they still lead every engagement in person, scoping in your office, on the tools during the build, across the numbers after handover.

    Behind them is a team of six, all in-house, building AI agents and custom systems for Australian businesses every day. The people who scope your system are the people who build it.

    Everything is built in our Brisbane office, no outsourcing, no hand-offs, no ticket queues. Walk in for a working session and the people at the desks are the ones shipping your system that week.

    • Always reachable

      Call any hour, any day of the week. You get the person who built your system, not a ticket queue.

    • Founders in the room

      Jack and Lachlan run every project start to finish. Nothing is handed off or outsourced.

    • Built, fixed and sorted

      Something breaks at 9pm, we fix it at 9pm. A new idea on Sunday is scoped by Monday.

    "Australian businesses don't need another tool. They need a partner who installs the system, owns the result, and is still there in month twelve."
