Unit 221B Raises $5 Million for Threat Intel Aiding Hacker Arrests

Unit 221B has announced raising $5 million in a seed funding round led by J2 Ventures, with additional support from Pipeline Capital and other investors, according to SecurityWeek. The New York‑based threat intelligence firm says the funds will be used to expand its eWitness platform and accelerate investigative collaboration and go-to-market efforts.

Founded by veteran threat intelligence and technology experts a decade ago, Unit 221B focuses on providing actionable threat intelligence, including intelligence that can lead to hackers getting arrested. The company notes that it has been involved in investigations that led to threat takedowns and the indictment and arrest of multiple cybercriminals, including last month’s arrest of RapperBot DDoS botnet administrator Ethan Foltz.

CEO May Chen-Contino is quoted saying collective action can change outcomes as investigators across enterprises, law enforcement, and governments are united. The article is dated 23 September 2025.
