Sayantan Chatterjee
Customer Success Leader
& AI Builder
I spend my days helping enterprise teams get the most out of their technology. Evenings, I build AI products that solve problems I care about.
About
Over nine years in the SaaS and AdTech world, I've worked with companies like CleverTap, Adobe, and Branch — managing enterprise portfolios, building customer success frameworks, and driving revenue growth.
But there's another side. I'm deeply fascinated by what AI can do when pointed at real, everyday problems. So I build things — apps that transcribe multilingual speech, journals that run entirely on your device, tools that make workflows smoother. I make apps, often without writing traditional code.
