Zephra is a production-ready autonomous marketing platform built for startups and SMBs. The platform is structured across three layers — a Context Graph that stores and grows business knowledge over time, an RL-based Decision Engine that optimises budget and channel decisions from live performance data, and a Multi-Agent Execution Layer that runs campaigns across paid, organic, social, and creative channels simultaneously. Server-side tracking and creative generation are already live. LinkedIn, SEO, and social execution agents are in active development. Pilot discussions are underway with Bosch India, Centena Group, and Leanonus across enterprise, retail, and services verticals.
