TestMu AI Introduces the Source-to-Verdict Loop in Kane CLI, Carrying Every Requirement to a Ship Decision With Portable Proof23.7.2026 16:45:00 EEST | Press release
TestMu AI (formerly LambdaTest), the world's first Agentic AI-powered Quality Engineering platform, introduced a source-to-verdict loop in Kane CLI, its natural-language testing tool. Building on Kane CLI's evolution from a browser automation tool, the loop carries a product requirement to a ship decision, writing the tests, running them in the local browser, collecting the proof, measuring coverage from what actually happened, and returning a verdict. As AI agents write, run, and fix tests, a green checkmark is no longer enough: a step that checks nothing passes, a test written against a spec that changed weeks ago passes, and an agent that says “done” without the click ever landing passes. Empty green and earned green are the same color on every dashboard, the number climbs while the risk does not move. Kane CLI closes that gap: it carries a requirement to a verdict, and proves every step of it. One loop. Source to verdict. You no longer hand Kane CLI a test script, you hand it your

Trulioo Launches AI Agent to Resolve Beneficial Ownership Where Global Registries Fall Short23.7.2026 16:00:00 EEST | Press release
Trulioo, a global risk intelligence platform, today announced the UBO Discovery Agent, the newest layer in Trulioo's UBO Discovery capability inside its business risk and Know Your Business (KYB) verification workflow. AI is reshaping fraud, making it easier for bad actors to hide, and harder for companies to catch them. This makes the already tough job of verifying who actually owns a business even more difficult. Determining a business's ultimate beneficial owner is an ongoing, acute challenge for companies: registry coverage is inconsistent across countries, and even where registries exist, they typically record shareholders and directors of record (rather than the people actually in control). That data isn't simply outdated, it reflects a structural lag: ownership changes and time passes before the filing is made and processed, so a lookup often shows who owned a business months or years ago, not who owns it today. Further, ownership chains that cross borders can break entirely onc
