My Summer at a 3-Person Startup Changed How I Think About Work

When I told my parents I was doing my summer internship at a startup with three employees and no office in Chennai, my mother went very quiet for a long moment. Then she asked if I had applied to TCS. I had not applied to TCS. I had instead applied to 40 startups cold, heard back from 6, interviewed at 3, and chosen the one that could not even tell me what my exact role would be.

That last part should have been a red flag. It was not. It turned out to be the whole point.

What the First Week Actually Looked Like

The startup was building a B2B SaaS tool for logistics companies. The founders were two IIT alumni and one person from IIM. They worked out of one of the founder's apartments in Velachery. I showed up on Monday and was handed a laptop, a Notion link, and a problem: their onboarding flow had a 68% dropout rate and nobody had figured out why. 'That is your project,' the CTO told me. 'Come back Friday with a hypothesis.'

I spent that week doing something no campus project had ever made me do: actually talking to users. I cold-messaged the ten customers who had dropped off. Five responded. One spoke to me for 45 minutes. She explained, in patient detail, exactly where the product confused her. I wrote it all down. I built a messy Miro board. By Friday I had four hypotheses ranked by my confidence level. The founders pushed back on all of them in the nicest possible way and we arrived at a fifth that was better than any of mine.

The Ownership Problem

In a big company internship you contribute to a feature. In a three-person startup you own an outcome. This sounds exciting in theory and it is genuinely terrifying in practice. There was a week in July when both founders were traveling for fundraising and it was just me and the third team member, a full-stack developer named Karthik who had been at the startup for three months. A critical bug dropped our signup conversion by 40%. Karthik was busy on a deadline. I had to debug it.

I spent eight hours on that bug. I found it. It was a race condition in the email verification flow that only appeared when users had a slow internet connection, which happened to be most of our users in tier-2 cities. I fixed it, pushed the fix, watched the numbers recover, and felt something I had never felt after submitting a college assignment. Not pride exactly. More like weight. The kind you feel when something actually matters.

What I Carry Forward

I came back to college with a very different relationship to ambiguity. Most of my classmates who interned at big companies came back with a polished project to put on their resume. I came back with something harder to articulate: a tolerance for not knowing what to do next, and the confidence that I could figure it out anyway. I also came back with a genuine understanding of PMF, user research, and why most features should not be built at all.

The stipend was ₹18,000 a month. I shared a room in a PG with two other interns from different colleges. We cooked most nights. I have never felt more adult in my life, and I mean that as a compliment. If you are choosing between a comfortable internship at a known brand and a chaotic one at a small startup, I am not saying choose the startup. I am saying: know what you are optimizing for. I was optimizing for how much I would learn per day, and nothing came close.
