The marginal cost of a bigger life is lower than you think

I grew up around the machines in my father's shop in Mexico, and today I am an engineer building a company at MIT called AgentsArmy. This is the story of how one quietly led to the other

That look

I was thirteen the year my father rolled the first computer controlled machine into his shop, and I stood there and stared at it for a long time, the way you stare at something you know is about to change your life. I catch myself making the exact same face today when I watch what AI is becoming.

The marginal cost of a bigger life is lower than you think

Choose your hard

Mile 24, Boston Marathon, 2024

I ran it beside my father, who has finished all seven of the great marathons of the world, and I was sure that the younger, stronger legs would carry me to the line well ahead of him. When I finally crossed it, gasping, I looked around to see how long I would have to wait for him, and found that he was already there, waiting for me.

Grit gets you moving, but grit and experience wins

Maggie

Maggie was a vice president at one of the biggest phone companies in the world, and the day I was admitted to MIT she walked away from all of it without a second thought so that we could chase the uncertain thing together. We married and we came to the adventure, and I am a lucky man, because everything I will ever build has her somewhere inside it.

Who is your Maggie?

Cozumel, 2024, my first triathlon

For my very first triathlon I chose a half Ironman, seventy miles of swimming, cycling and running, even though I had never once swum in open water until the morning of the race. The only thought that carried me the whole way was a simple one, please do not die, because Maggie is waiting for you at the finish.

Bravery is not a thought, it is a step

My entrepreneurship funeral

My first company at MIT died in a single quiet conversation, when Brian Halligan looked at me and told me that I was a nice guy but he would not put a single dollar behind me, because the idea and I simply did not belong to each other. It stung for weeks, and it was also the kindest and most useful thing anyone had ever said to me, because it sent me looking for the real reason I was doing any of this, and AgentsArmy was born out of that search.

The circle

You have already met the boy who started all of this, and he is the reason any of it exists at all. No founder I admire has ever done it alone, and this is the circle that carries me, my mother and father, Maggie, Sandra, Moni, Sebastian, the friends and mentors along the way, a great deal of luck, and a little divine intervention.

Believe, take action, dream big

Why my favorite book is Death of a Salesman

Willy Loman spent his whole life chasing a borrowed dream, a version of success that was never really his, and it made him miss the people who loved him while they were still right in front of him. Linda's line has never left me: attention must be paid.

I read it as a founder the way you would read a warning label, because the work is not only to chase the dream but to keep asking whether the dream is still mine, whether it still makes the people I love bigger instead of smaller, and whether it has grown in the same direction I have grown.

An unexamined dream can quietly turn toxic, and the only ones worth keeping are the ones still connected to who you actually are

This is also why literature matters to me as much as any spreadsheet, because a good book lets you live a life that is not yours and see the world through eyes that are not yours, which is the cheapest and fastest empathy I have ever found, and which happens to be the whole job of building something for other people.

Read the reflection that shaped how I see this play
Dear Class, Thank you for today's discussion. As I said at the start of class, this play has transcended both time and culture, and there is a reason for that. It touches on certain universal aspects of the human condition. Among other things, it is a play about the human desire to leave some mark on this world during our short stay in it, and the difficulty, at times, of figuring out how exactly to do that in a manner that is true to ourselves. Deep down Willy just wanted what we all want, to be loved and accepted. But because he could not love and accept himself, he failed to see all the love that surrounded him and all that he could be proud of in the life he had built. Linda's call that attention must be paid, and Charlie's offer of friendship and assistance, are powerful lessons in what it looks like to be there for a fellow human being in pain. The message we should take from this play is not that we should stop dreaming. We need our dreams. They sustain us, they inspire us, they impel us to grow. And yet unexamined dreams can be toxic. It is a good idea to check in periodically with our dreams, to ask if they are still serving us, if they are connected to the things we truly value, if they are strengthening and not fraying our most cherished relationships, and if they have evolved as we have evolved. Best, Cat

What I believe

  • Choose your hard, because both roads ask everything of you and only one of them ends in regret
  • Useful is rarer than nice, and one honest word is worth a hundred kind ones
  • Bravery is a step and not a feeling, so you take it first and let the rest catch up
  • Average is expensive, because safety is usually a mirage that arrives later with a bill

On my shelf

  • Death of a Salesman by Arthur Miller, the one I keep returning to
