Genuine long-term wealth rarely comes from trading in and out of whatever is popular.
Instead, it often comes from owning a handful of elite businesses, the sort that keep expanding their markets, improving their earnings power, and strengthening their competitive edge year after year.
On the ASX, several ASX growth shares fit that description, but two in particular stand out as long-term compounders with momentum firmly behind them.
Here are a couple of unstoppable ASX growth shares to buy and hold for years.

Life360 Inc (ASX: 360)
Life360 has transformed from a family-tracking app into a full-scale digital safety platform with growing subscription muscle. What makes the company so unstoppable isn't just its massive user base, it is the rate at which that base is evolving.
Recent updates show explosive momentum. It reported accelerating subscriber growth, rising average revenue per user (ARPU), strong cash generation, and global monthly active users approaching the 100-million mark. This scale gives Life360 significant optionality.
With a platform that already lives on the smartphones of tens of millions of families, Life360 can expand into adjacent categories such as home security, insurance partnerships, vehicle telematics, and commerce integrations. Very few consumer apps enjoy this type of engagement or monetisation leverage.
And because Life360's model is subscription-driven, revenue compounds each year even without massive user growth. Add the potential benefits of international expansion and its advertising business, and it is clear why many analysts view it as one of the ASX's emerging global leaders.
Morgan Stanley recently put an overweight rating and $58.50 price target on its shares.
NextDC Ltd (ASX: NXT)
Another ASX growth share that could be a top buy and hold option is NextDC. It provides the physical backbone the digital economy runs on.
Demand for data centre capacity has surged with the rise of cloud computing, streaming, ecommerce, and especially artificial intelligence. Every AI model, every cloud migration, and every tech platform relies on compute and storage, which NextDC delivers through some of the most advanced, energy-efficient data centres in the region.
What makes NextDC unstoppable isn't just industry tailwinds, it is the company's aggressive build-out strategy. Major new facilities are coming online across key markets, and each one typically ramps up utilisation over many years, driving recurring revenue higher without proportionate increases in cost.
An example of this is the deal it has just signed with ChatGPT's owner, OpenAI. The two parties are looking at building the largest data centre in the southern hemisphere, with OpenAI as its anchor tenant.
Combined with the rest of its development pipeline across Australia and the Asia-Pacific region, this leaves NextDC well-placed for growth over the next decade and beyond.
Morgans is bullish on the company and recently upgraded its shares to a buy rating with a $19.00 price target.
