# Rahul D Sarker: Fractional CMO, Performance Marketing & RevOps

> Rahul D Sarker is a growth operator and fractional CMO with 14+ years in marketing and growth. He helps growth-stage startups, SaaS/B2B, D2C, real estate/PropTech, WordPress product companies, agencies, and professional services build predictable revenue by combining Fractional CMO leadership, Performance Marketing, RevOps, and AI-powered automation into one integrated growth engine. Based in Kolkata, India; works with companies across India and globally.

Core thesis: more leads, more ad spend, and more tools are not the answer, better systems are. Every engagement starts from revenue, unit economics (CAC, LTV, payback), pipeline, and attribution, not vanity metrics or channels. Rahul is the single operator who owns strategy and execution end to end, so companies get one system, one forecast, and one owner of the number instead of a stack of disconnected vendors.
