Hi, I'm
Tanul

I've gone from selling to businesses to bootstrapping an edtech app used by 25,000 students — and now I'm building mobile apps while finishing my MBA at SPJIMR.

My edge: I've sold, I've built, and I obsess over why users do what they do.

Building with AI

MBA @ SPJIMR · Shipping products between lectures

Living through B-school gave me a front-row seat to higher-ed's unsolved problems.
Built tools to fix them — 500M+ Cursor tokens later, the habit stuck.
AcadCal was adopted by the SPJIMR program office to help students manage academic schedules.

03Featured Story

I spotted a UX gap. Airlearn shipped the fix in 7 days.

What happens when a PM finds a real problem, backs it with user evidence, and reaches out directly to the CEO.

Day 0

Spotted a broken activation loop

I started using Airlearn and loved the concept — but after finishing my first lesson, I had no idea how to continue. For a language learning app, that's a critical activation problem. I wrote a detailed post on exactly what was broken and how I'd fix it.

Day 5

Found the proof, then made the case

Five days later: a Reddit thread titled 'Why is there no continue button?' — dozens of users, same frustration. I compiled the evidence and DM'd Gaurav Munjal (CEO) directly, pairing my earlier analysis with real user complaints. That combination is hard to ignore.

See the Day 5 post

Day 7

They shipped the fix

At 1 AM on Day 7, a DM from Gaurav arrived: "Sorry about this. We have fixed it now." Seven days from post to fix. It's a reminder that specific, public feedback — backed by user evidence — actually moves the needle.

04Sidequests

Things I Build on the Side

Real tools, real users, real constraints — built between lectures and deadlines.

AutomationAdoptionOps

AcadCal

Managing a B-school calendar across batches, faculty, and events is chaos. AcadCal makes it seamless — lives in Google Sheets, adopted by SPJIMR's program office.

Cassr

Case discussions are where B-school learning happens — but students rarely feel prepared. Cassr bridges the gap between faculty, students, and case materials.
