Get to know me

Shipped features that make companies millions every month; won hackathons. I've also killed two of my own products.

They all come from the same skill & Villain's Hat's VRSD methodology came out of doing both.

Pavitra S. Tandon

16+ years shipping products & features.

Lived and worked across 4 continents. Designed and shipped products across Finance, Consultancy, Energy, Entertainment, and Aerospace. Led teams, hit KPIs, moved metrics that C-suite, finance and legal teams trust and engineers respect. Also walked away from things that didn't meet my bar.

2 hackathons won, 1 came second. Ryanair's first 24-hour hackathon. Smartbox's AI Hackathon. Smartbox's Integrations Hackathon. Not for the trophies. For the practice of shipping a real thing on a tight deadline, with compliance and accessibility intact.

I built a feature that worked too well.

At Ryanair, I designed an AR bag sizer that helped users measure their bags before they flew. It took me 8+ months to get the business case into the backlog. Users loved it. The ML accuracy improved by the day. Numbers tracked perfectly with user feedback and research.

Then it was quietly shelved.

It worked so well it stopped people from making expensive bag upgrades at the airport. Fewer people in the queues. Margins dropped. The metric that paid my salary got worse the moment the feature helped users get what they actually needed.

I always believed in balancing business goals with user needs, but that moment rewired how I think about products.

I learned to notice when a design that's right for the user is wrong for the business, and when it's the other way around. I learned to nail and name the tension instead of pretending it isn't there. I learned that the user the product never wrote for isn't always vulnerable. Sometimes it's the user the product wrote for, served too well.

That tension is what Villain's Hat formalized.

I killed two of my own products, on purpose.

I'm telling you this because it's where the methodology originated from. It's not the only thing I've done but it's one that I've landed on after numerous trial and errors. The killed products are why I wrote the methodology.

Roastfluencer

Roastfluencer in action, a short demo of the roast flow.

This was a really fun one, until it wasn't. Roastfluencer was a Gemini-powered roast generator. It emulated standup-comedian kind of roasts, a person just needed to upload a picture. It was technically clean, the roasts worked, but the guardrails slipped. I could have shipped it, but I put myself in the shoes of others who may use this.

Imagine this: A group of kids in a school corridor using it to gang up on a classmate they've just bullied and taken a photo of. They upload the photo to Roastfluencer, and the roast has them pointing and laughing at that kid. I've been the bullied, I know how much it hurts without AI in the mix. The AI made the cruelty cheaper, faster, and at scale. I decided to kill it before launch.

echonote

echonote 'Create new message' UI: sender and recipient fields, message tone selector (Casual, Emotional, Formal, Playful, Legacy), message body, attachment options for picture, video, and voice, plus schedule date.
echonote's message composer, tone selector included.

A platform for people in critical health situations to leave messages for their loved ones upto 10 years into the future. echonote was originally inspired a few years after I lost my mother. I wish I could hear her voice, her laughter, hear her nag even. This was the kind of product I cared about; the kind that, if it worked, would matter the world to me.

I built seven AI guardrail agents. I named each one, gave them a persona with JDs. I tested them in a multitude of scenarios. Then a passing thought changed it all. What if, just what if, someone is trying to blackmail someone and the messages are scheduled in advance, maybe had pictures attached too? Another example is, imagine this. 'I love you' from someone you love (like my mom) vs 'I love you' from a stalker will have very different reactions. One will bring memories and tears, the other will paralyze and make one shiver in angst. I'd hate to think the effect this would have on someone already broken by grief, getting hit again on the anniversary.

The guardrails caught most scenarios. They couldn't catch enough of them, and so I shut it down.

I wouldn't consider closing my own products naivety. It's a quality bar. I know I could work on the AI agents but would that stop the humans from finding workarounds to do evil?

This is where I draw the line. If I won't ship a product I'd be ashamed of, I won't help you ship one either.

Same skill, 4 surfaces.

The methodology that came out of 16 years in UX and killing those two products is now applied across everything I do.

Pavitra Tandon presenting on AI agents and probabilistic UX

Belgrade, 2026. Talking about probabilistic UX for AI agents when they think back.

in Belgrade, building Villain's Hat, taking my time to do it right.

Living in Belgrade has its own challenges with the language, but they're all dog-lovers here, so it's great to be here with Om and our cocker spaniel Pari. We're in the process of adopting a child. We've lived across 4 continents - India, New Zealand, Ireland, and now Serbia. I'm learning Serbian, and I already speak English, Hindi, Kannada, plus a tiny bit of Spanish, Portuguese, Korean, Chinese and Japanese.

I've wanted to get into Y Combinator for 20 years and I applied last year with a fashion app focused on transitioning shoppers experiences from volume driven to value driven which in turn changes how fast fashion brands slow down, reducing amount of garments that land in our landfills. They said no. The reason I think was I had the business case, I had a prototype, but no Tech co-founder. Villain's Hat is the version I'm building with AI as my Tech co-founder.
