What we build
Some ventures sell services, some sell products, some are software. They all have to solve a real problem and pay their own way.
Real businesses with real customers, from marketing services to automated retail.
Tools and platforms we build, own and maintain.
Built small first, then improved through real use.
Android games with simple loops and plenty of personality.
Systems that take repetitive work off people's plates.
Products that can be sold and delivered online, with low running costs.
Calculated bets on new markets, tested properly before we commit.
How we operate
No buzzwords. Every venture moves through the same six steps, and the loop never really ends.
Start with genuine customer pain or a clear market opportunity.
Build the smallest useful version and prove demand before investing heavily.
Automate repetitive work where technology genuinely helps, not because it's fashionable.
Real-world results beat assumptions every time.
Double down once a business or product proves demand.
Markets and technology change. The portfolio changes with them.
Ground rules
About
Castle Ventures is the Australian-owned parent company behind Rank Xpert, Castle Vending and our software and games studio. We start ventures, run them day to day and grow the ones that prove themselves.
We're not an investment fund and we don't manage outside money. Every venture in the portfolio is one we build and operate ourselves.
