Continuous learning platform

AI, Design, Product, Leadership, Career and more

AI is rewriting how products are built, and learning can no longer be a course that ends. So pifo is becoming a continuous learning platform: learn from people who build and lead products, alongside peers who keep you going.

A continuous learning platform

More information won't make you better. Direction will. pifo is built on how adults learn, with structured learning for every stage of your career, at the depth and price you choose.

pifo Shots (in beta) · Open to all in mid-December

Learn complex subjects
in a way that sticks.

Shots is a platform for learning AI, product, design, leadership, data and career, one nugget at a time. Each nugget is one idea you apply as you learn it, so it makes sense.

Why Shots matter?

AI keeps changing, and nobody has hours to spare. Shots turns learning into a daily practice: one nugget a day, one idea you apply as you learn it. Your brain learns something new by hooking it to something it already knows, so each idea builds on the last. Small steps, every day, is how you keep up.

Daily nugget

One idea a day, shared with everyone. We all learn the same thing, the same day.

Learning streak

Learn as many nuggets as you like, and watch your streak grow.

Challenge week

Every month, a challenge week for everyone. Apply what you learned to a real use case.

Office hours and mentors

Weekly office hours, and mentors who answer your questions.

Active community

Learn alongside peers. Share what you built and see what others made.

Choose what you learn

Your friction is your curriculum. Pick what you need, and tell us what you want next.

About pifo

Started in 2019, to give back.

Karthi Subbaraman

I'm Karthi Subbaraman.

25+ years building digital products, designing complex systems, and leading design in Fortune 50 companies. Products used by millions. Multiple ventures built from scratch. But none of that is why pifo exists.

pifo is my purpose project for this lifetime. My holy cow. It exists because leaving this world better than you found it isn't optional. It's a responsibility.

I spent years working at the intersection of product design, business design, and something I've come to call life design. The same principles that shape great products shape great people. How we think. How we grow. How we show up. I needed a system for all of it. So I built one for myself first. The frameworks, the tracks, the community. I kept building and refining for years. Then I shared it to find out if someone like me would benefit. My LinkedIn has always been that too: learnings and reflections to my younger self, shared with intention.

We build product innovators for the AI era. They give back. We build more, especially in Tier 2 and Tier 3 cities where access to world-class learning is still rare. No complicated model. Just a flywheel powered by people who believe in paying it forward.

pifo is a Section 8 not-for-profit registered in India. There are no investors. No shareholders. No deadline. We plant this tree knowing we may never enjoy the shade. That's exactly the point.

That is how we leave this world a little better than we found it.
