G’day and welcome to your weekly edition of Overnight Success - your download on all the important things that have happened in the Aussie startup ecosystem. 🚀

I had a piece published titled "The Australian company helping power the manosphere" by our friends at Capital Brief, about the Melbourne-based crypto casino Stake and its associated streaming platform, Kick.

Also, I’ll be at Sunrise this week! HMU if you’re going! (Hit reply!)

📊 Aus startups raised $763 million across 40 rounds in Q1 2026, roughly flat year-on-year but with fewer deals and larger average cheques. Investors are backing fewer companies with greater conviction, according to the Traxn Q1 2026 Australia report.

Syenta, a chip packaging technology company spun out of the Australian National University, has raised $36 million ($26 million USD) in a Series A round led by Silicon Valley venture firm Playground Global, with the National Reconstruction Fund contributing $10.1 million of that total. Existing backers Investible, Salus Ventures, Jelix Ventures, and Wollemi Capital returned for the round, joining a cap table that also includes Blackbird, Brindabella Capital, CIA-backed In-Q-Tel, SGInnovate, and OIF.

Pat Gelsinger, a Playground Global general partner and former Intel CEO, will join the Syenta board as part of the raise.

Syenta's core technology is called Localised Electrochemical Manufacturing, or LEM is a lithography-free process that enables high-density interconnects for advanced chip packaging. The claim is that it achieves finer-pitch connections between chips within existing manufacturing infrastructure, without requiring facilities to be rebuilt from scratch.

Early results from LEM production have shown 40% fewer process steps compared to conventional approaches, alongside improvements in bandwidth and manufacturing efficiency. The company expects to begin semiconductor production by 2027.

Advanced chip packaging, the way chips are stacked and connected at a microscopic level, has become a genuine constraint on AI system performance. The density of interconnects limits how much data can flow between chips, and existing lithography-based approaches struggle to scale efficiently.

The funding will go toward commercialising LEM for high-volume production and expanding into the United States, where Syenta is establishing a base in Arizona. The raise follows a $2.2 million round in late 2022 and an $8.8 million pre-Series A in August last year.

Instant, an AI agent platform that automates retention marketing for eCommerce brands, has received a strategic investment from HubSpot Ventures, bringing the company's total funding to more than $30 million. The company has not disclosed the size of the new cheque. The investment follows a period of sharp growth: Instant's AI email and SMS agents hit $1 million in ARR within 70 days of their 2025 launch, and ARR has grown 10x over the eight months since.

Instant has grown from 500 brands to more than 1,500 over the past year, with flagship names such as Liquid I.V., ThirdLove, and David Protein now on the platform. Average ROI across its customer base has climbed from 15x to 76x over the same period, and Instant's AI-powered retention emails have generated $1 billion in incremental revenue across its Shopify brand base.

For brands that go all-in on the platform, Instant's agents account for 30% of annual site revenue via email and, in most cases, generate three to five times more revenue than the legacy email platform they replaced. 

Liam Millward, founder of Instant, relocated to New York full-time in February 2026 to lead Instant's American push. The company is scaling product and engineering alongside the US expansion, with the new funding earmarked for both.

Ideally, an AI-powered market research platform has raised $13.4 million in a Series A round led by Shearwater Capital, with support from Altered Capital and Icehouse Ventures. The round values the company at more than $83 million. In two and a half years, the Sydney and Melbourne-based startup has grown to 56 employees and counts DoorDash, Telstra, Google, and Asahi among its users.

The market research industry is worth around $90 billion globally, but its incumbent model of lengthy briefs, weeks-long fieldwork, and six-figure invoices has remained largely unchanged for decades. By the time findings land, the market has often moved on.

Ideally's pitch is overnight consumer insight at a fraction of the traditional cost, without sacrificing quality. The platform is built on real human responses, with AI applied to sharpen both question design and the analysis that follows. The distinction from pure-AI survey tools matters to the company: It has explicitly positioned itself around human responses at a time when the industry is leaning harder into synthetic data and AI-generated panels.

More than 250 brands across APAC and the US now use the platform across product development, campaign testing, and category research. One of the more concrete case studies involves Treasury Wine Estates, where Ideally compressed a nine-month new product development cycle to 90 days. Work that ultimately produced a wine by the 19 Crimes label, called the “Snoop Dogg Cali Red Blend,” with advertising that evokes Tupac, the late rapper. 

Ideally, opened a New York office in early 2026 and has since grown US revenue by 350%, with customers including Duckhorn, Tilray, and Rémy Cointreau. The Series A funding is earmarked to accelerate that expansion.

Alongside the raise, the company is launching Ideally Canvas, a product designed to replace one-off research studies with a continuously updated picture of a brand's consumer. Rather than a static snapshot, Canvas builds a compounding dataset over time, feeding into creative and commercial decisions from the earliest stages of a campaign or product cycle.

Antioch, a robotics simulation platform, has raised $8.5 million USD in a seed round at a $60 million USD valuation, led by A* and Category Ventures, with participation from MaC Venture Capital, Abstract, BoxGroup, and Auckland-based Icehouse Ventures. The raise comes just months after the company closed a $4.3 million USD pre-seed.

The core product lets engineers spin up thousands of virtual test environments for robotic AI training, integrating with existing development workflows and identifying failure modes before hardware is ever involved. Use cases span construction, autonomous vehicles, and manufacturing, sectors where physical testing cycles have historically been measured in days or weeks.

Mellsop, a New Zealander, co-founded Antioch alongside Alex Langshur, former Head of Product at Deep Grey Research; Colton Swingle, a former Google DeepMind engineer; and Collin Schlager, a former Meta Reality Labs researcher.

The company is positioning itself at the infrastructure layer of what it argues will be a larger wave than the LLM boom. Knowledge work, the territory that software and AI have disrupted over the past several years, represents a global market of around $8 trillion USD. The physical world, encompassing manufacturing, logistics, construction, energy, and agriculture, is a market the company puts at more than $50 trillion USD.

The argument is that reliably deploying AI in physical environments requires the same kind of closed-loop testing infrastructure that software development takes for granted — and that infrastructure for robots doesn't yet exist at scale.

Renewable Metals, a battery recycling technology company, has raised $12 million in a Series A led by existing investor the Clean Energy Finance Corporation, with support from Neglected Climate Opportunities, UK-based end-of-life recycler European Metal Recycling, impact VC Investible, and Climate Tech Partners. The raise follows a $16.1 million seed round completed across two tranches in 2024.

Renewable Metals has developed a patented hydro-metallurgical process capable of recovering more than 95% of lithium, cobalt, nickel, copper, and manganese from lithium-ion batteries, including Lithium Iron Phosphate chemistry. The process runs in modular plants that can extract critical minerals across a single production line, at up to half the cost of existing approaches.

The combination of high recovery rates, LFP compatibility, and modular deployment is the core of the company's competitive argument against established Chinese recyclers, which have spent years building scale and cost advantages that Western competitors have struggled to match.

The funding will support a demonstration plant in Kewdale, Western Australia, that is about to come online, with the capacity to process up to 2,000 tonnes of batteries annually, which equates to roughly 4,000 end-of-life EVs. A second commercial plant is planned for the Hunter region in New South Wales.

And it looks very similar to the way he mapped it out two years ago. The expectation was that this would eventually flip, just like it did in previous tech cycles, such as cloud. But two years later, even after massive growth, the structure hasn’t changed much.

The kicker: He expects this to hold for the next ~10 years. Food for thought!
