Retiring rich is rarely about one lucky investment.
It usually comes from owning high-quality ASX shares for long periods and allowing strong earnings growth to compound over time.
That is why I like ASX growth shares with real competitive advantages. The best ones can keep expanding, reinvesting, and becoming more valuable long after they already look successful.
Two ASX growth shares I think could help investors build serious long-term wealth are named in this article.

Pro Medicus Ltd (ASX: PME)
Pro Medicus has become one of the ASX's most admired growth shares.
The healthcare technology company provides imaging software used by hospitals and radiology groups. Its Visage platform helps clinicians view, manage, and interpret medical images quickly and efficiently.
What I like about Pro Medicus is that it solves an important problem in a demanding environment.
Medical imaging volumes continue to grow, and healthcare systems need software that can handle large amounts of data without slowing clinicians down. Speed, reliability, and accuracy are important in this market.
That gives Pro Medicus a powerful position.
It has also shown an impressive ability to win large contracts with major healthcare organisations, particularly in the US. These contracts can be long-term in nature and deeply embedded once implemented.
The share price can look expensive. But I think the market is willing to pay up because the business has exceptional margins, a strong balance sheet, and a large global opportunity.
For investors trying to retire richer, I think Pro Medicus is the kind of business that could keep compounding if it continues executing well.
Breville Group Ltd (ASX: BRG)
Breville is a consumer brand rather than a software or healthcare company, but I think it has one of the more attractive long-term expansion opportunities on the ASX.
It has built a strong reputation in premium kitchen appliances, especially coffee machines. That is important because the business is not just selling household products. It is selling better at-home experiences to customers who are willing to pay more for quality.
I think coffee remains the clearest example.
Many consumers have become more selective about the coffee they drink at home. Breville sits in a useful position because it offers products that can appeal to people who want a more premium experience without relying on cafes every day.
The growth runway comes from taking that brand into more markets, launching new products, and deepening its position in categories where design and quality matter.
There are risks. Consumer spending can weaken, tariffs and supply chain costs can affect margins, and premium appliances are not immune to a tougher economy.
But I like that Breville has a global brand-building opportunity. If it keeps proving that it can win beyond Australia, I think the business could be much larger over the next decade.
Foolish takeaway
I think these ASX growth shares could play a major role in building long-term wealth.
Pro Medicus offers exposure to world-class healthcare software, while Breville brings a global premium brand story.
They will not move smoothly, and valuation still matters. But if these businesses keep growing over the next decade and beyond, I think they could help investors build serious wealth before retirement.
