Austin-based Sevco, which offers customers analytics on the security of their information assets across different systems, raised a $15 million Series A funding this June, and Jay Leek’s new VC firm, SYN Ventures, led the round. Launched with cofounder Patrick Heim, the former security chief for Dropbox and Salesforce, SYN Ventures has a new $165 million fund to back more cybersecurity startups like Sevco.
