Siddhant Aneja

Siddhant Aneja is a Partner at ChaptersOS and the founder of Per4mance Guru — a performance marketing agency rated among the Top 10 in India and Top 5 Emerging Agencies by Mid-Day.

He's spent close to a decade building, running, and selling businesses across offline and e-commerce — from launching fashion brands to scaling D2C companies through paid ads, social, and creative. Per4mance Guru works with brands across India, the US, UK, UAE, and Australia, consistently delivering 5–7x ROAS for clients in fashion, beauty, food, and lifestyle.

Before going full agency, Sid co-founded ZeroKaata and built Watch Me — both giving him a founder's-eye view of what growth actually looks like from the inside. That's the lens he brings to every brand he works with at ChaptersOS.
