About Spearbit & Cantina:

We're building Cantina, an AI Security Platform that secures the world's code. Originally the "GitHub for Security" — connecting security researchers with the projects needing their expertise — Cantina has evolved into a multi-product platform spanning Apex, Clarion, and Cantina Bounties. It has powered major competitions and serves many of the leading projects in Web3, supporting collaborative security reviews, public and private competitions, bug bounty programs, AI-driven code analysis, and a security operations center (SOC) that monitors, triages, and responds to live alerts and threats.

Similar to how cloud-security startups emerged previously, Cantina aims to be the definitive code-security platform for the future.

We are always growing, evolving, and looking for incredible people to join our mission.

If you love what we’re building and want to be a part of it, we want to hear from you! We'll reach out if a future opportunity arises that may be a fit for your skills and experience.
