Some ASX shares should really appeal to growth investors because of how they're growing revenue and offering new products or services to customers. Many companies that change how households or businesses operate have been great investments.

For example, REA Group Ltd (ASX: REA) has altered how Australians buy and sell property, while CAR Group Limited (ASX: CAR) has changed how motor vehicles are transacted.

There are great technology investments available to Aussies on the ASX share market and I'd like to share two of those with you.

Xero Ltd (ASX: XRO)

This company provides accounting and business operations software to small and medium businesses around the world.

Its biggest markets are English-speaking countries, including Australia, the United Kingdom, New Zealand, the United States, South Africa and Canada. At the end of the first half of FY25, it had 1.86 million Australian subscribers, 614,000 subscribers in New Zealand, 1.07 million in the UK and 365,000 North American subscribers.

Xero has multiple appealing factors for growth investors, including its very loyal customer base and high gross profit margin. In HY25, the company reported a very high loyalty rate of approximately 99%. This is a good sign that customers love the product and enables Xero to implement price increases with little loss to subscriber numbers.

In the HY25 result, Xero reported a gross profit margin of 88.9%, an increase from 87.5% in HY24. It can turn almost all new revenue into gross profit, which can be spent on growth (such as marketing and software development) or flow onto the operating profit (EBITDA) and net profit lines of its financials.

HY25 saw operating profit rise 25%, gross profit grew 27%, EBITDA increased 51%, and net profit went up 76%.

In the long term, I believe Xero's subscriber numbers and profit can grow considerably. This could make today's valuation seem cheap.

Global X Fang+ ETF (ASX: FANG)

I believe most growth investors should have a bit of exposure to the world's leading global growth businesses.

I'm talking about companies like Microsoft, Meta Platforms, Amazon, Alphabet and others.

According to Global X, the FANG ETF aims to give investors exposure to 10 of the biggest companies at the "leading edge of next-generation technology".

The other companies it invests in include Nvidia, Broadcom, Apple, Netflix, ServiceNow and Crowdstrike.

This fund is regularly re-weighted to be equal between these 10 names, so each holding has roughly a 10% allocation.

The FANG ETF has performed very strongly. It has achieved an average total return per annum of 27.3% over the past three years. While I don't expect the next three years to be as good, it could still be a compelling investment, given how these underlying companies are advancing various offerings (such as smartphones, online video, AI, and so on).

With a large allocation to each stock, we can significantly benefit from their performance. This is why I think Aussie growth investors would like this investment.
