Seven Startups Raise $274.7 Million in Australia's Big Funding Week

AI healthcare platform Heidi has secured $475 million in new capital at a $1.26 billion valuation, anchoring a week in which seven startups raised a combined $274.7 million.

The headline figure splits in two. Heidi's core $140 million Series C was led by existing investor Blackbird, with contributions from Phoenix Court, Point72 Private Investments and Headline. A further $335 million in non-equity growth funding comes from American venture capital firm General Catalyst through its Customer Value Fund.

Co-founded in 2021 by Dr Tom Kelly, Waleed Mussa and Yu Liu, Heidi records appointments and produces structured documents for medical professionals to review. The raise ranks among the most significant capital raises of any Australian venture this year. The newly minted unicorn plans to scale what Kelly described as a "fully-fledged AI partner" — one capable of handling vital background work and giving clinicians more time for face-to-face care.

Amber: $78.5 million for European expansion

Renewable energy supplier Amber Electric raised $78.5 million in a Series E, nearly doubling its planned round size. Morgan Stanley's climate tech fund 1GT led the round, with support from existing investors ETF Partners, state government-backed Innovation Victoria and E.ON.

Amber has built Australia's largest residential battery automation product, holding roughly half the local market. Co-founder and co-CEO Chris Thompson said the funds will drive expansion across Europe.

"We've built the winning energy automation platform in Australia, and this funding will enable us to extend our leadership across Europe," Thompson said. "Our partnership with E.ON is already showing what's possible, and we're excited to build on that momentum with more partners across the region."

HEO Robotics: $37 million to reach geostationary orbit

Satellite inspection startup HEO Robotics raised a $37 million (US$25 million) Series B to expand its satellite imaging network into geostationary orbit. Beaten Zone Venture Partners led the round, joined by the federal government's National Reconstruction Fund Corporation, which tipped in $10 million, plus Dcode Capital and existing investors Airtree and Salus Ventures.

The funding follows an Airtree-led $12 million Series A in 2023 and a $3 million seed round in 2021 led by Winton Group founder David Harding and Y Combinator.

HEO mounts cameras aboard other satellites, alongside its own sensors, to photograph and assess the condition and behaviour of other spacecraft. Its software plots what to photograph and analyses the results. The company, which emerged from UNSW Founders in 2017, has access to more than 50 sensors in orbit and has deployed eight of its own.

Kinoxis Therapeutics: $6.75 million plus a $2.5 million grant

Dementia treatment biotech Kinoxis Therapeutics raised $6.75 million in equity funding and secured a $2.5 million grant from the federal government's Medical Research Future Fund. Deep tech VC Main Sequence led the round with $5 million as a new investor, with principal Elaine Stead appointed a director. The grant comes via the CUREator+ Dementia & Cognitive Decline program, delivered by Brandon BioCatalyst, ANDHealth and Dementia Australia.

The Sydney University spinout, founded in 2017 and now based in Melbourne, previously raised a $14.5 million Series B two years ago and a $5 million Series A2 in December 2020. Its cap table also includes Uniseed, UniSuper, Sydney Uni, Stoic VC and US-based Avicella Capital. The $9.25 million in new cash will fund clinical trials and treatments for dementia-related agitation and pain.

Medcast: $5.4 million for an AI copilot

Medical edtech Medcast landed $5.4 million to make its AI clinical knowledge platform, MedLuma, the trusted AI copilot for Australian GPs. Queensland medical software business Best Practice Software led the investment.

Founded in 2013 in Bowral by CEO Dr Stephen Barnett and chief product officer Justin Lewis, Medcast has delivered clinical education and professional development to more than 100,000 registered healthcare professionals. The raise will fund headcount growth in technology and clinical teams, plus product development and integration with clinical software, including Best Practice's practice management systems.

RentBetter: $5 million from EVP

Sydney startup RentBetter raised $5 million from local VC EVP to build out an AI-powered self-management system. Its platform lets property owners advertise rentals, screen applicants against tenancy databases, sign leases, coordinate repairs and track income and expenses.

CEO Jeremy Goldschmidt, a former management consultant for Boston Consulting Group, Capgemini, Blackdot and IBM, founded the company in 2016 as a side hustle while working at ANZ. RentBetter previously raised $3.2 million, including a $1.9 million Series A in January 2022.

OpenDebt: $2 million pre-seed for a US push

Sydney AI fintech OpenDebt raised $2 million in a pre-seed round backed by Blackbird and early-stage VC Antler. The funds will scale the team and operations and explore US partnership opportunities, where household debt in delinquency tops $1 trillion.

Former Westpac data and AI executive Norman Yan, a 15-year banking veteran, founded OpenDebt with Jonas Tischer 12 months ago. The startup takes a compliance- and consumer-focused approach to debt recovery, deploying AI agents in multichannel conversations. The AI identifies why an account is unpaid and responds accordingly — offering simpler settlement paths for ready payers and specialist support for people in financial hardship. OpenDebt already works with several local lenders and collection agencies.

With Heidi joining the unicorn ranks, Amber scaling into Europe and HEO pushing toward geostationary orbit, this week's cohort signals that Australian startups are raising serious capital for global ambitions rather than domestic consolidation.
