Silicon Quantum Computing: $40 million

The federal government’s National Reconstruction Fund (NRF) has doubled down on Silicon Quantum Computing (SQC), pouring another $40 million into the Sydney scaleup, less than three months after investing an initial $20 million.

The new funds are for the development and expansion of SQC’s quantum chip manufacturing capability.

Alongside the $60 million from the NRF, the federal government also holds around a one-third stake in SQC, having invested $40 million, including $25 million in 2017.

This funding is part of a larger round currently underway, after the quantum scaleup last raised a $50 million Series A in 2023 at a $195 million valuation. Other investors include CBA, Telstra, UNSW, and the NSW Government.

The NRF says SQC is the only company globally capable of manufacturing quantum chips with atomic precision as well as quantum enhanced-AI products for enterprise and government.

SQC builds quantum chips for commercial-scale quantum systems. The UNSW spin-out was founded in 2017 by former Australian of the Year and Tech Council director Professor Michelle Simmons.

Australian dental startup Dentroid has raised $32 million at a $265 million valuation for its needle-free dental tech. It has also signed a strategic partnership with French dental products manufacturer Septodont, which includes a global licensing arrangement for its flagship Nuralyte technology.

As first reported by the Australian Financial Review (AFR), the fresh funding round included participation from Septodont itself, as well as participation from local backers such as former WiseTech Global director Michael Gregg.

Launched in Canberra back in 2017, the Canberra-based startup is developing technology designed to reduce the need for dental injections.

Founded by dentist-turned-CEO Omar Zuaiter and robotics engineer Alaa Habeb, Dentroid has spent the past nine years developing technology aimed at providing pain relief during dental procedures without traditional local anaesthetic injections.

According to the company, the Nuralyte device uses pulses of light to induce analgesia in teeth and gums, with the goal of reducing or eliminating the need for needles during some treatments.

Dentroid’s technology has undergone stage one and stage two clinical trials through partnerships with the University of Maryland, the University of Queensland, Griffith University, and the University of Sydney.

Australian construction fintech Earlytrade has secured roughly $14.2 million (US$10 million) in a new funding round as it accelerates its expansion in the US and invests in AI capabilities.

The round was led by S3 Ventures and Brick & Mortar Ventures, and the company has said the fresh cash injection will be used to grow its US commercial operations and build agentic AI into its subcontractor payments marketplace.

While Earlytrade has not publicly disclosed the new funding amount, it did say its total funding to date is $35.5 million (US$25 million).

This includes a $12.5 million (US$8.9 million) Series A round in 2022 and an $8.4 million (US$6 million) funding round in 2019, which is verified on Crunchbase as well as previous reporting.

When queried by SmartCompany regarding whether this means the latest round was around $14.2 million (US$10 million), a representative confirmed yes.

Founded by Guy Saxelby and Piers Symons in 2018, Earlytrade operates a marketplace that allows general contractors and subcontractors to trade working capital. The company says this gives subcontractors earlier access to payments and helps ease cashflow pressures across construction projects.

Smart50 finalist ReSmart has raised $1.14 million via On Market, in what is the startup’s third equity crowdfund in three years.

Originally known as RecycleSmart, the recycling startup helps offer doorstop recycling for households, businesses and councils, to help them dispose of tricky items that can’t go in kerbside bins.

ReSmart secured support from 783 investors in its latest capital raise, along with continued backing from Antler, which has now invested in the startup across each of its funding rounds to date.

In July 2025, the company raised $1.5 million via equity crowdfunding platform Birchal and from wholesale investors. This followed two previous Birchal campaigns, which saw the company secure $1.15 million in May 2024, and $1 million in July 2023.

ReSmart now operates across Sydney, Melbourne, Brisbane, Perth, Adelaide and Hobart. It works with close to 30 councils, as well as large companies such as Qantas, Westpac, Canva, Lululemon and The Iconic. To date, it has completed more than 440,000 collections and diverted more than 2 million kilograms of waste from landfill.

ReSmart was ranked 14th on the 2025 Smart50 list, based on a three-year revenue growth rate of 66% and $2.8 million in annual revenue.
