Tracebit

Tracebit is a cybersecurity company building a product that helps security teams detect intrusions in their cloud environments quickly and accurately. The company’s approach centers on canaries: decoy tripwires and assets deployed to deceive attackers. When an adversary interacts with these decoys, Tracebit surfaces a low volume of highly relevant, actionable alerts at the moment it matters, rather than relying solely on complex rules or anomaly models that attackers can evade.

The company positions itself against the shortcomings of existing intrusion detection in the cloud. In Tracebit’s view, both external and internal adversaries can dodge difficult-to-interpret rules and anomaly models, leaving security teams without the signal they need. Tracebit’s mission is framed as “sophisticated security with simple solutions” — giving defenders a practical way to assume breach at scale and detect and contain security incidents in minutes rather than months.

Tracebit serves security teams at organisations running complex cloud environments. Publicly named customers include Riot Games, Synthesia, Docker, Coveo and Snyk, alongside other clients the company has not disclosed. The product supports detection work across all three major cloud providers, and the company reports processing billions of events a week on a stack that includes AWS, infrastructure as code and continuous delivery.

Alongside its product, Tracebit runs a security research practice. Its researchers have disclosed vulnerabilities in Google’s Gemini CLI and published research on AWS account enumeration techniques and data exfiltration via CloudTrail. The company is expanding this function, turning findings into detections, blog posts and conference talks, and contributing to the wider security community.

Tracebit is backed by venture capital firms and cybersecurity angels and advisors. Investors include Accel, Tapestry VC, FirstMark, MMC Ventures and CCL, and the company announced a $20m Series A led by FirstMark. Advisors and backers quoted by the company include security leaders such as Josh Yavor, Mandy Andress, Guy Podjarny, Stevie Case, Geeta Schmidt and Stephen Whitworth. Tracebit has appeared on industry lists including Creandum’s Euro Seed top 50, Sifted’s 2025 London Startups to Watch and Accel’s Euroscape Top Startups 2024.

The company has grown quickly from a very small founding team. According to its careers materials, it expanded from two people to roughly 14-18 staff within about 18 months and plans to roughly triple headcount in the coming year. Tracebit is headquartered in Fitzrovia, London, with a presence in Manhattan, New York City. Teams work from offices near Warren Street tube station in London and in New York, and the company describes itself as office-first, with most roles based in the office five days a week, though it notes flexibility case by case and makes exceptions for some roles such as security research.

Tracebit describes its culture as collaborative, curious and high-agency, with the pace and ambition of an early-stage startup. Employees work closely with the founding team, ship every day with little bureaucracy, and stay close to customers and to their craft. The company emphasises learning fast, seeing the impact of work daily, and having fun along the way, and it offers perks such as equity options, a cycle-to-work scheme, monthly socials and lunches, and office refreshments.
