ZeroPath
ZeroPath (YC S24) is an AI-native application security platform that delivers comprehensive code protection beyond traditional SAST. Founded by security engineers from Tesla and Google, ZeroPath combines large language models with deep program analysis to deliver intelligent security testing that finds real vulnerabilities while dramatically reducing false positives.
Unlike traditional SAST tools that rely on pattern matching, ZeroPath understands code context, business logic, and developer intent. This enables identification of sophisticated security issues including business logic flaws, broken authentication, authorization bypasses, and complex dependency vulnerabilities.
Our comprehensive security suite covers the application security lifecycle:
1. AI-powered SAST
2. Software Composition Analysis with reachability analysis
3. Secrets detection and validation
4. Infrastructure as Code scanning
5. Automated PR reviews
6. Automated patch generation
and more...
ZeroPath integrates seamlessly with GitHub, GitLab, Bitbucket, Azure DevOps and many more. The platform handles codebases with millions of lines across Python, JavaScript, TypeScript, Java, Go, Ruby, Rust, PHP, Kotlin and more.
Our research team has been successful in finding vulnerabilities like critical account takeover in better-auth (CVE-2025-61928, 300k+ weekly downloads), identifying 170+ verified bugs in curl, and discovering 0-days in production systems at Netflix, Hulu, and Salesforce.
Trusted by 750+ companies and performing 200k+ code scans monthly.

Emotion
Emotion is an efficient and adaptable CSS-in-JS library tailored for crafting CSS styles via JavaScript, accommodating both string and object styles while ensuring an excellent developer experience with features like source maps, labels, and testing tools. It presents two robust usage patterns; one is a framework-agnostic method that requires no special setup yet facilitates vendor-prefixing, nested selectors, media queries, and class composition through its CSS and CX functions. The second pattern is specifically optimized for React, offering advanced functionalities such as the CSS prop for direct styling, akin to the style prop, yet with enhanced support for nested selectors, media queries, and theming features. This variant also allows for seamless server-side rendering without configuration, native theming options, and full compatibility with ESLint tools. Additionally, Emotion provides styled-component-like APIs that allow for both tag-based and component-based styled elements, promoting dynamic styling driven by props. Furthermore, these capabilities make Emotion an appealing choice for developers seeking to streamline their styling processes across various frameworks.
