I'm Saptarshi — Head of Customer Success at BambooBox. 5+ years building CS functions that don't just retain — they grow revenue. Mentor, strategist, and the guy who insists CS is the most underrated lever in SaaS.
I'm Saptarshi, a Customer Success leader based in Bangalore. Currently heading CS at BambooBox — a MarTech startup — where I own everything from onboarding and implementation to renewals and expansion, managing a team of 5 across CS and Implementation.
With 5+ years across SaaS, AgriTech, and MarTech, I've built CS functions from scratch, fixed broken ones, and helped founders understand why post-sales is your actual growth engine. I've been featured in 4 publications for my revenue-first take on Customer Success.
Outside my day role, I mentor students, freshers, and career-switchers on Topmate — helping people break into CS, navigate pivots, and build profiles that recruiters actually notice. I'm also open to GTM and CS consulting for early-stage startups.
"CS is wrongly treated as a cost centre. It operates at the intersection of retention, expansion, and advocacy — and should act as a strategic partner to sales."

From BYJU'S to BambooBox — every role taught me something different about customers, growth, and what it takes to build trust at scale.
CS strategy for founders, career guidance for freshers, GTM advisory for startups. All bookings via Topmate.
