Nexad is the company behind Soku AI, an autonomous marketing agent that connects to your ad accounts, analytics and website and then runs a continuous perceive–decide–act loop across analysis, creative and optimization. Instead of leaving you with backward-looking dashboards, it monitors Google, Meta, TikTok and ChatGPT Ads alongside GA4 and your site, explains what changed, generates and tests new creative, and applies optimizations with human-in-the-loop approvals. It is an AI-native advertising platform for teams that want their growth work executed, not just reported.
