Regional NSW startup Cauldron Ferm has raised $13.25 million in a Sequence A2.
The spherical was led by present deep tech investor Essential Sequence Ventures, supported by Horizons Ventures, SOSV, and NGS Tremendous.
It follows a $9.5 million in Series A two years in the past.
The brand new capital will allow Cauldron to satisfy rising demand from governments and firms, and the startup is taking a look at retrofitting present amenities to deploy hyper-fermentation at companion websites.
Cauldron beforehand scored $4.3 million from the federal government’s Industry Growth Program.
Based in 2022 by Michele Stansfield and David Kestenbaum, the deep tech startup relies in Orange, three-and-a-half hours west of Sydney. It has a 30,000-litre demonstration facility there.
Cauldron was recognised in the 2025 Startup Daily Best in Tech awards as best regional startup. The enterprise was additionally not too long ago named one in every of Quick Firm’s 2026 World’s Most Revolutionary Firms.
Cauldron’s hyper-fermentation know-how permits the creation of proteins, supplies, and specialty chemical compounds with dramatically decrease environmental affect—lowering electrical energy utilization by 55%,and water by 20%.
Biomanufacturing makes use of residing cells as programmable factories, the place bio-engineered microbes convert easy inputs like sugars into worthwhile merchandise.
Productive microbes
Stansfield stated Cauldron’s tech retains these microbes in a extremely productive regular state and operating processes repeatedly for lengthy durations, which will increase output whereas considerably reducing manufacturing prices.
Bio-based meals components, chemical compounds, and nutraceuticals are preliminary potentialities for the method.
“For biomanufacturing to compete in industrial sectors, bioproducts must ship on prices, scale, and high quality. Bioprocess innovation is how we get there,” Stansfield stated.
“We’re honoured to be backed by a devoted group of skilled buyers and proud to be recognised as one of many World’s Most Revolutionary Firms. This milestone displays the affect of our platform at a time when governments and firms are urgently looking for aggressive bio-based options to handle provide chain strain.”
Estimates recommend up to 60% of the physical inputs to the global economy could be produced biologically, reshaping how important merchandise are sourced and secured.
Essential Sequence companion Phil Morle stated that “in a market distracted by AI hype cycles, we’re backing the exhausting, bodily work of scaling biology” to make bioindustrial manufacturing commercially inevitable.
“Cauldron is proving that biology can run repeatedly, predictably, and on the volumes international provide chains demand,” he stated.
“Hyper-fermentation closes the hole between breakthrough strains and dependable, cost-competitive manufacturing.”
