When I think about building a portfolio that can grow over time, I look for businesses with clear direction, strong positioning, and the ability to keep expanding their opportunity set.
These are companies that continue to build on what they already do well, while opening up new avenues for growth along the way.
Here are three ASX shares I think fit that description.

Hub24 Ltd (ASX: HUB)
Hub24 is a business that sits in the background of the investment industry, but its role continues to grow.
It provides the infrastructure that advisers use to manage client portfolios, and as more wealth flows onto platforms, its relevance increases.
What I find compelling is how the business builds depth over time. Each new adviser relationship brings a pipeline of clients and assets, and those assets often grow as markets rise and contributions continue. That creates a layering effect where growth compounds on top of itself.
Hub24 is also expanding what its platform can do, which allows it to capture more value from each relationship. Over time, that combination of scale and functionality can drive meaningful growth.
Breville Group Ltd (ASX: BRG)
Breville takes a different path. It operates in consumer products, but its strength lies in how it approaches brand and innovation.
The company focuses on premium kitchen appliances, with a reputation for design and quality that resonates across global markets. What stands out is how it continues to build its presence internationally.
Growth comes from entering new regions, expanding product categories, and strengthening its brand positioning. That creates multiple pathways for the business to keep moving forward.
For me, Breville is a reminder that consumer businesses can scale globally when they combine strong branding with consistent product development.
Sigma Healthcare Ltd (ASX: SIG)
Sigma Healthcare brings a structural growth story. Following its merger with Chemist Warehouse, the business now dominates distribution and retail, which creates a more connected position within the healthcare supply chain.
What I find interesting is how that structure can evolve. With greater visibility across both sides of the business, there is potential to improve efficiency, optimise inventory, and strengthen relationships with suppliers and customers.
For me, Sigma represents a business that is reshaping its role within the industry, with the potential to build a stronger and more integrated model.
Foolish takeaway
I think these are the kinds of businesses that can earn their place in a portfolio over time.
They continue to expand their reach, deepen their advantages, and build on what already works.
That is what gives me confidence in their long-term potential.
