How do you structure your business as a solopreneur building multiple SaaS products?

Hey guys 👋

I'm a solo founder currently building my first SaaS product, and I'm planning to launch a few more niche products in the future. I'm based in Australia and operating under my ABN (sole trader), but I’m trying to figure out the best way to structure things for the long run.

Some questions I’ve been thinking about:

• Do you operate under a single business name/entity and treat each SaaS as a product?

• Or do you register a new business name for each app/brand you launch?

• Do you use a holding company or parent brand (like “XYZ Labs”) and group everything under that?

• How do you handle things like Stripe, terms of service, privacy policies, and legal identities across multiple products?

• And how do you balance simplicity with branding clarity?

Would love to hear how you’ve structured your solo business, what’s worked, and what you’d do differently if you started again.

Thanks in advance to anyone who shares 🙌
