ROI Sphere is a senior-led performance marketing consultancy built for brands that demand real results. We specialise in architecting full-spectrum growth engines — covering paid media across Google, Meta, LinkedIn and YouTube; rigorous conversion rate optimisation; custom marketing intelligence dashboards; and go-to-market strategy. Founded by alumni of IIT Bombay and Washington University's Olin Business School, with 8+ years of hands-on expertise, we have managed over ₹83.5 crore in ad spend across India, the US, Europe, and APAC. We don't celebrate impressions. We measure success in revenue generated per dollar spent — nothing else counts.
