Verdict Machine, a four-person startup in Y Combinator's S26 batch, has launched an AI product for screening proposed on-chain transactions and preventing malicious ones, aimed at institutions including banks and asset managers, according to the accelerator's company profile. Its headline traction claims remain unverified, and the proof-of-concept work it cites involves prospective customers rather than volume the company has protected itself.
What the product does
The company describes its offering as AI cybersecurity for the digital assets held by financial institutions. Its LinkedIn page says a single live model supports three functions: malicious-transaction prevention, continuous cyber diligence and security-posture management.
Y Combinator's launch announcement argues that generic rules lack organizational context. Attackers, it says, exploit the relationships among vendors, employees and counterparties, and not merely isolated wallet transactions. That is the framing of the company and its backer, not an independent comparison. A commentary by KarenZ of Foresight News, carried by ChainCatcher and dated Oct. 29, 2026, similarly says the product assesses proposed transactions against institutional context and policies.
To illustrate the idea, Y Combinator's promotional video uses a fictional scenario involving a catering service and vault access, in which an authorized person is manipulated into granting malicious entry. It is a marketing explanation. It is not footage of a real attack that was prevented, or of a customer deployment.
How the product actually enforces a block is unclear. The company did not disclose its enforcement mechanism in the material reviewed, and its website, verdictmachine.com, returned no readable page body when checked.
Who it targets
Y Combinator's profile lists banks, asset managers, digital-asset infrastructure businesses, DeFi organizations, and companies that use stablecoins or tokenized real-world assets.
As of Nov. 5, 2026, the profile reports proof-of-concept work with asset managers and digital-asset infrastructure providers that handle billions of dollars weekly. It also reports evaluations with the digital-asset teams of major banks. That volume describes the prospective customers' systems, not anything Verdict Machine has protected. The research found no confirmed live deployments at banks or asset managers.
Vela Partners' startup radar, dated Sept. 1, 2026, repeats the asset-manager claim and adds an evaluation at one of the world's largest banks. This is secondary repetition, not confirmation from a bank.
The company has named no customers. Pricing and general availability were not disclosed in the research.
The team
LinkedIn's public employee list names Dan Danay, Isaac Grossman, Liran Kogan and Igal Mininberg, and places the company in the 2-10 employee band. Company Launch Tracker #98, dated Aug. 12, 2026, reports a four-person team.
Danay, the chief executive, previously worked at Check Point. The company published an Aug. 8, 2025 article under his byline, with the title Head of Web3 Security, announcing real-time threat detection on the Cardano mainnet. The article is more than 12 months old and does not show that Verdict Machine supports Cardano.
In a founder announcement reproduced on Kogan's LinkedIn profile, Danay said the institutional digital-asset problems he encountered at Check Point motivated the startup. He identified Kogan as a former product colleague there and Grossman as an earlier collaborator at keyTango. Vela Partners' profile says one founder previously led blockchain-security product work at Check Point, and payments and foreign-exchange products at Payoneer.
The public record contains a few discrepancies. Danay's announcement describes Airmada as a YC S15 company, while Vela identifies it as W16. Eight Capital's Aug. 12 spotlight says Verdict Machine was founded in 2024, whereas Y Combinator says 2026.
A crowded field of competitors
Rivals are plentiful. Blockaid launched Risk Exposure on May 12, 2026, offering real-time address and transaction monitoring and programmatic action when risk thresholds are crossed. Its Aug. 13, 2026 case study with Midas describes transaction-behavior analysis and simulation, with integrations involving Fordefi and Fireblocks. That case study was written by the vendor.
Chainalysis sells Hexagate, which offers adaptive monitoring and automated response to exploits, phishing and wallet compromise, and which targets asset managers and exchanges. Forta announced Firewall on OP Enterprise on Aug. 20, 2026, screening transactions before execution at the sequencer, with Kraken's Ink as its first adopter. TRM Labs offers Wallet Screening, which assesses risk before authorization, and in August 2026 added AI-agent access and rolling-window behavioral monitoring. Fireblocks, in a Feb. 10, 2026 white paper, describes policy controls, transaction simulation and real-time threat intelligence.
TRM's release complicates any suggestion that rivals rely only on static rules.
Funding and what comes next
Verdict Machine has announced no funding round. Y Combinator's standard deal, checked Nov. 5, 2026, is $500,000: $125,000 for 7 percent, plus $375,000 on an uncapped MFN SAFE, a simple agreement for future equity with a most-favored-nation clause. Those are accelerator-wide terms, not a disclosed Verdict Machine financing.
Danay is listed as a speaker at the STG-3 online cybersecurity symposium on Nov. 5, 2026, alongside Soda Labs CEO Avishay Yanai and zeroShadow CEO Casey Golden. The listing is an event announcement, and the research does not confirm that the event took place.
For now, the evidence for Verdict Machine rests on its own description, a backer's endorsement and unnamed prospects. Customers named on the record, or a disclosed enforcement mechanism, would be the first real tests.
