Could buying these ASX shares make me rich?

Wealth in the share market doesn’t usually come from one brilliant trade. In my experience, it comes from owning the right ASX shares early, sticking with them through the ups and downs, and continuing to invest along the way.

That’s why I’m drawn to smaller, high-quality ASX growth shares that still have long runways ahead of them. Not because they’re guaranteed winners, but because if they execute well over many years, the compounding can be powerful.

Here are three ASX shares that fit that mould for me.

Megaport Ltd (ASX: MP1)

Megaport is a good example of a business doing something essential rather than flashy. It provides on-demand connectivity between data centres, enterprises, and cloud providers. In simple terms, it helps move vast amounts of data quickly and flexibly across the world.

As cloud computing, artificial intelligence, and hybrid IT architectures become more complex, that flexibility matters more. What I like most is that Megaport isn’t standing still. The acquisition of Latitude has expanded it beyond connectivity into compute infrastructure, which deepens customer relationships and increases potential revenue per client.

This is still a relatively small company in the scheme of global digital infrastructure. If management executes and demand continues to grow, long-term shareholders could be rewarded. But it would likely be a journey with plenty of volatility along the way.

SiteMinder Ltd (ASX: SDR)

SiteMinder operates in a niche that quietly benefits from global travel without taking on the capital risk of airlines or hotels. Its software helps hotels manage bookings, pricing, and distribution across multiple channels.

What appeals to me here is the embedded nature of the product. Once a hotel relies on SiteMinder to manage room inventory and revenue, switching becomes inconvenient and risky. That creates stickiness and recurring revenue over time.

The global hotel market is enormous, and SiteMinder’s penetration remains relatively modest. If it continues expanding internationally and improving margins as it scales, the compounding effect over a decade or more could be meaningful. This isn’t about next quarter’s result. It’s about owning a platform that becomes more valuable as travel becomes more digital.

DroneShield Ltd (ASX: DRO)

DroneShield is probably the highest-risk name on this list, but also potentially the one with the most upside.

It develops counter-drone technology used by military, government, and critical infrastructure operators. As drones become cheaper and more capable, the need to detect and neutralise them grows. Unfortunately, this is not a problem that is going away any time soon.

What I find interesting is the mix of hardware, software, and increasingly recurring revenue through software upgrades and support. Defence procurement is lumpy, and share prices can swing wildly on contract timing. But if DroneShield continues to win credibility and expand its installed base, long-term value could build quietly behind the scenes.

Foolish Takeaway

I don’t buy ASX growth shares expecting instant results. I buy them because, over the long term, a small number of successful businesses can do an outsized share of the heavy lifting in a portfolio.

Megaport, SiteMinder, and DroneShield all operate in growing markets, are still relatively small, and have paths to becoming much larger businesses if things go right.

That doesn’t make them safe or certain. But for patient investors willing to invest consistently and think long term, these are the kinds of shares I believe can change the shape of a portfolio over time.
