Brad Slavin is the founder and General Manager of DuoCircle, the company behind AutoSPF, DMARC Report, Phish Protection, and Mailhop. He founded DuoCircle in 2014 to solve the SPF 10-DNS-lookup problem at scale and has led the company's growth to 2,000+ customers. Brad's focus is product strategy, customer relationships, and the commercial and compliance side of email authentication (DPAs, SLAs, enterprise procurement) rather than hands-on DNS engineering.
