Hi, I'm Shantanu Sahay

I'm the founder of Greater Than Services. Over the past year I've designed and built every project on this page myself, using modern AI tools to move fast and double-checking every screen before anything goes live.

That speed is what lets me keep prices low. You deal with me directly, not a sales team, and I explain every step in simple words, so you always know what you're paying for.

Tell me what you need. I'll reply within a day.

Send a message on WhatsApp or email me. No forms, no sales calls.
