There are numerous potential buys on the ASX, but I want to talk about two particular names that could be the best two ASX growth shares to buy, in my opinion.
Both of the stocks I'll highlight have built an impressive market share in their sector and are still growing rapidly.
I believe they could be two of the best-performing S&P/ASX 300 Index (ASX: XKO) shares over the next three years.

Siteminder Ltd (ASX: SDR)
Siteminder says it's the world's leading hotel distribution and revenue platform with its Siteminder software. It also offers Little Hotelier, an all-in-one hotel management software offering.
The business generates 135 million reservations worth over A$85 billion in revenue for its hotel customers each year.
It's growing rapidly – in the FY26 half-year result, annualised recurring revenue (ARR) increased 29.7% to $280.3 million. It benefited from accelerating contributions from the smart platform alongside continued strength across the broader business. Not many businesses are growing that quickly at the moment.
The ASX growth share is winning new hotels and growing its revenue per hotel. HY26 net property additions were 2,900, taking total properties to 53,000 – it's putting a greater focus on winning larger hotels. HY26 average revenue per user (ARPU) rose 11.3% to $435, with growth driven by smart platform initiatives and rising product adoption.
The nature of being a software business means it has significant operating leverage, which is helping increase its gross profit margin, the operating profit (EBITDA) margin and net profit (loss) margin.
The ASX growth share has also launched 'Siteminder Powered', allowing certain hospitality technology companies to integrate Siteminder's distribution engine in their own platforms. The first partner is Mews and this will include the smart platform products of channels plus, demand plus and dynamic revenue plus.
Existing joint customers of Siteminder and Mews are expected to transition to the integrated experience.
At the time of writing, it's down more than 50% since October 2025, so it looks great value to me.
Temple & Webster Group Ltd (ASX: TPW)
Temple & Webster is the leading pure play online retailer of homewares and furniture in Australia, which puts it in a very pleasing to benefit from a strong tailwind.
E-commerce adoption is steadily increasing in the western world. The level of e-commerce adoption in homewares and furniture in Australia has reached around 20%, but in the UK it's around 30% and in the US it's approximately 35%. To me, that suggests Australia could climb towards 30% in the coming years.
The company sells hundreds of thousands of products, though most of them are shipped directly by suppliers – this enables the ASX growth share to be capital-light and generate lots of cash flow.
I'm expecting its profit margins to rise in the coming years as its growing scale helps with various benefits, as well as plenty of AI usage in different parts of operations.
I've also got my eye on the home improvement segment, which is small but growing at a much faster pace than the core business – in five years, I hope this division will be a material contributor to the overall company.
It has fallen more than 75% in the past year, so it's so much better value.
But, these aren't the only two opportunities out there.
