Let’s rethink the way we solve what matters.

About rethink:cards

Hi! I’m Sebastián Prida, co-founder of Medu, writer, and the mind behind rethink:cards.

I’ve spent the last few years juggling my startup (check out Medu), collaborating with non-profits, working in education, and diving into plenty of creative projects along the way. Basically, trying to make hard stuff feel a little less… hard.

From building a medical education app that doesn’t feel like med school, to interviewing Nobel laureates and entrepreneurs, to leading brainstorms and teaching at Uni, I’ve noticed one thing over and over:

Ideas are everywhere.

What we’re really missing are the ones that actually solve what matters and the tools to bring them to life. That’s what I’m all about: making things happen. Every day. Definitely not an expert yet, but totally obsessed.

That’s where frameworks come in… and they’ve become my favorite tools. I’ve been using them since 2018, back when I was still in med school and already feeling the pull to do things differently. I didn’t want to follow the traditional path. I wanted to create. Fast-forward a few years, and I’m still meeting with my team every week to tackle real problems in our startup, discovering new frameworks. They’re powerful, practical, and once you get the hang of them, surprisingly fun to use.

And if there’s one thing I’m really into (besides a good beach holiday), it’s creating things. Big things, weird things, useful things. That’s what rethink:cards are. Something I built to help people like you and me build stuff that matters.

So what are rethink:cards?

They’re a thinking toolkit. A guide to stop starting with an idea, and start with a real human need, and make it happen.

I created three types of cards to help you rethink your way:

  • Insight Cards → to see the big, systemic challenges worth tackling. This first series dives into healthcare, highlighting urgent issues like mental health, maternal and infant mortality, preventable accidents, and major diseases.

  • Enabler Cards → to explore emerging tech and tools that can turn those challenges into opportunities.

  • Building Cards → my personal collection of go-to frameworks to help you actually make it happen.

Rethink:cards are for creative teams, entrepreneurs, strategists, educators, social innovators, and anyone who loves asking “how might we?” and then doing something about it.

If that sounds like you, or if you’d like to chat, invite me as a speaker, or co-create a workshop, let’s connect:
