AI Startups to Watch (Oct 5): Firmus, Pandektes & OneByZero
AI startups moved real money on Oct 5: Firmus priced a $4.94B IPO at a $30.6B valuation, Pandektes raised 13.5M euros and OneByZero took $20M.
Five AI startups moved real money on Monday, and three of them are outside the United States. An Australian data-center builder priced the second-largest IPO in its country's history at a US$30.6 billion valuation, a Copenhagen legal-data company raised to attack LexisNexis and Westlaw, a Singapore deployment firm took its first outside cheque, and two seed-stage companies opened new categories in robot safety and automated pentesting.
Yesterday's edition covered the Armadin raise and Supabase's Turso acquisition, and the AI startups archive has the rest of the week.
Firmus prices a US$30.6 billion IPO for AI data centers

The IPO priced at A$11.00 a share to raise A$7.1 billion, about US$4.94 billion, at a US$30.6 billion equity valuation, with roughly US$30 billion of debt implying an enterprise value near US$60 billion. On Oct 5 Bloomberg and Reuters reported Firmus will allocate about half the offer, up to US$5.5 billion including the greenshoe, to existing investors. Bookbuilding opens Oct 6 and ASX trading is targeted for Oct 23. It is Australia's second-largest IPO ever and the fourth-largest globally in 2026, and the valuation has nearly tripled since August, when Nvidia, Blackstone, Coatue and Jane Street backed a US$2 billion round at US$10.5 billion post-money.
Pandektes raises 13.5 million euros to open legal data

The round is a 13.5 million euro Series A led by Alstin Capital, with PROfounders, Scale Capital and existing investors, taking total funding to roughly 17.4 million euros after a 2.9 million euro seed in February 2025. Valuation was not disclosed. Pandektes says it will compete with Karnov, LexisNexis and Westlaw and license its data to other legal AI developers, which turns walled legal content into a commodity input and threatens the incumbents' subscription moat.
Safeworld exits stealth to sell robot safety testing

It tests AI-controlled robots inside simulations populated with realistic human models, running thousands of scenarios at a time before a robot ships. Source: TechCrunch
It emerged from stealth on Oct 5 with a US$12.2 million seed co-led by Shine Capital and a16z Speedrun, with Box Group, the Carnegie Mellon University Endowment, Innovation Endeavors, SV Angel and angels from Nvidia, Google DeepMind, Waymo, Meta and Salesforce. Valuation was not disclosed and this is the company's total raised. If insurers and regulators adopt third-party safety evaluations, Safeworld becomes a compliance gate on physical AI deployment.
OneByZero takes US$20 million for enterprise agent rollouts
OneByZero is a Singapore company founded in 2023 by Niket Vaidya and Vibhore Kumar, who previously built and sold Unscrambl. It embeds engineers inside large enterprises to wire models into legacy systems, and governs what those agents can touch through its NEO platform and "AI Coworkers". It has 51 to 200 employees across nine markets. Source: Tech in Asia
The US$20 million Series A is led by Jungle Ventures and is OneByZero's first outside funding. Valuation was not disclosed. It is more than double Southeast Asia's median Series A of US$8 million in the first half of 2026, and the company will use it to expand in Japan and push NEO into healthcare and the public sector. It competes with the systems integrators its founders came from, and with AI SaaS products that cannot govern production deployments.
Fleuret AI raises 4 million euros to automate pentests

The 4 million euro pre-seed is led by RAISE Ventures, with Auriga Cyber Ventures, Wind Capital, Better Angle and angels including Eric Fourrier of GitGuardian and Jules Veyrat of Stoik. Valuation was not disclosed and this is the total raised. Fleuret quotes 4,000 euros per engagement against 15,000 to 30,000 euros for a manual pentest, and hosts findings on Scaleway in Paris to stay EU-sovereign. If that pricing holds, it compresses the red-team consultancy market.

It is the clearest open-source attack yet on CUDA lock-in, and it did not cost Huawei a dollar of new hardware sales. Source: Reuters
