Salezilla is a San Francisco-based AI sales automation platform founded in 2018, focused on helping B2B companies automate their client acquisition through cold email outreach. The platform's core proposition is replacing manual prospecting and copywriting with AI-driven systems that operate at scale while retaining human-level personalization quality. The platform centers on an AI SDR called Rex, which automates prospect research and compiles targeted lead lists by pulling data from LinkedIn and business databases. Rex is designed to eliminate the manual database-searching work typically done by sales development representatives, generating thousands of on-target prospects quickly based on a company's ideal customer profile. Email personalization is handled via GPT-driven technology that extracts specific information from each prospect's company website and incorporates it into outreach messages. This allows campaigns to appear individually crafted while running at automated scale. Salezilla reports 78% average open rates and 7% average reply rates based on campaign data from June to October 2025. The platform also provides fully managed email infrastructure: domain procurement, DNS setup, email authentication, domain warmups, volume ramp-up schedules, and ongoing deliverability testing to maximize primary-inbox placement. Salezilla offers both a self-service SaaS model and a fully managed outreach service where they handle strategy and execution end-to-end. CRM and workflow integrations are available via Zapier. As of 2026, Salezilla remains an active private company with approximately 12 employees. It raised $100K in early funding from investors including Right Side Capital Management and DEEPCORE. The company is active and has not been acquired or shut down.
