Personal Update (Big changes!) As we start to wrap 2025 I wanted to share some big changes that just happened in my life. TL,DR: Pachama got acquired by Carbon Direct, I had a second child, a beautiful baby girl, We are moving the family to Argentina for some time. Pachama acquired by Carbon Direct After 7 intense years of advancing the mission of restoring nature to solve climate change, we decided that joining forces with another leading company in climate action was the most appropriate move to ensure that our mission would continue to expand its impact for the long future with resiliency and resourcefulness. It was of course mixed feelings: it had been very rewarding and fun (while super hard!) to be the founding CEO and be able to create a unique culture of very passionate and talented individuals focused on nature. So passing the keys of the ship was both humbling and relieving. We chose Carbon Direct because they too have an amazing culture, talent and full focus on unlocking impactful climate solutions powered by science and technology. Together with a large part of our team, I have joined them as SVP and I plan to stay to help integrate and advance our -now larger- mission. I’m proud of all the impact that we had along the way and the ripple effect we created and I look forward to continuing my life mission for nature and the planet. Ping me if your company needs help on climate solutions! Welcoming our second child Almost exactly 2 years after the birth of our first child Andes, our second was born, a baby girl who we named Coral. The birth was again a spiritual experience for my wife and for myself, and our household is now a joyful, beautiful chaos. Having kids is truly the best of life and it changes perspectives and priorities. Moving to Argentina After almost exactly 18 years since I left Argentina, we decided to move back! This is an experiment and we are aiming to try it for at least 2 years. I love California and will dearly miss it. We have built an amazing community in the Bay Area and I get endless inspiration from its incredible surrounding nature and the unmatched creativity of Silicon Valley. But Argentina feels right for so many reasons. Having our extended family there to support us with the kids and allowing them to enjoy them while they are little is priceless. I’m also very excited for this moment of Argentina: it feels like a truly historical moment where the country can jump towards prosperity, and I’m excited to contribute by mentoring the next generation of entrepreneurs and helping sustainable development projects. Latin America can play a critical role in the 21st century and I’m excited to be “in territory”. I will be based in beautiful Buenos Aires, near the ecosystems of the great Rio de la Plata and I look forward to visiting Patagonia, the great north and beyond. Ping me if you come by! In a fun turn of events, all these changes happened at the same time (my last few months have been quite busy!) and while each were decided individually they are all somehow connected to each other. It is a new beginning for me and my family and I’m very excited about. I have been and will probably continue to be a bit absent in social media, as I seek to be present with everything else. I wish you the very best for your new year ahead. Vamos!

@sdianahu Congrats genia!

I'm deeply grateful and honored YC has changed my life twice: first as a founder, and now as someone who gets to back and support ambitious talent that's unproven feel lucky to do this work, and even luckier to do it with people I admire so much

@ycombinator @garrytan 💯👊 @garrytan

AI for Low-Pesticide Agriculture @garrytan Farmers are stuck in a bad loop: use more chemicals, get diminishing results, pay more, take on more risk. And they can't just stop, because if pests win, crops die. AI that can identify individual weeds in real time, robotics that can treat one plant instead of blanketing a field, and new biological solutions mean this problem finally looks solvable.

AI has stopped being a feature and started being the foundation. We're excited about a new wave of startups rebuilding software, services, and silicon— and pushing AI into the physical world. ycombinator.com/rfs

@sytses Epic! Big hugs my friend

I’m going Founder Mode on my cancer. Below is Elliot Hershberg’s article about my cancer journey. It gave language to something I’d been doing instinctively over the past year: managing my health in Founder Mode. Manager mode assumes that existing systems will surface the best options. When I was first diagnosed with cancer in 2022, I delegated the crucial analyses and decisions about my care to others. In late 2024, when my cancer reappeared and my doctors told me I had exhausted the standard of care and there were no trials for my situation, I realized that assumption might, quite literally, kill me. Founder Mode was my only option. Founder Mode meant going deep on every diagnostic and treatment option. It meant assembling a team of physicians and scientists to work from first principles to understand what was possible beyond standard protocols. Together, we paved new roads to access the very cutting edge of science and technology. Today, thanks to the efforts of many people around the world and the support of my wife Karen, I currently have no evidence of disease. But my fight with cancer is far from over. My team and I continue to develop treatments and strategies in case it returns. More importantly, I now understand firsthand the challenges patients face in order to secure their own data and necessary treatments, particularly personalized medicines. I increasingly see my role as removing structural barriers—breaking down walls that prevent data, treatments, and technologies from flowing where they’re needed. One of the core principles of the first company I founded, GitLab, was radical transparency, and it’s a principle I am bringing to my cancer care. To that end, I am going to be sharing more about my experiences, my treatments, my data, and what I am building to make the path that I’ve been on easier for others to follow. Please subscribe to my mailing list on sytse.com to stay updated. Lastly, I want to thank those who have been on this journey with me. There have been too many to all thank here but I appreciate every one of you. I did want to mention Jacob Stern, Alfredo Gonzalez, and Jeremiah Wala; the amazing teams at Private Health Management (shoutout to Jenn and Eva) and Willy Hoos and Pathfinder Oncology; Nima Afshar and Private Medical; Sant Chawla and the Sarcoma Oncology Center; John Connolly and his team at the Parker Institute; Will Hudson at Baylor College of Medicine; Kamil Slowikowski for his work on osteosarc.com; and Jeff Tsao, Will Gibson, Ali Samiei, Scott McConnell and the rest of the team at the Briger Foundation for Oncology Research.

Vibe code project of the week: A soundboard of my toddler's cutest words $20 mic off Amazon + Descript to slice up each word + Claude Code to clean up the audio quality + Lovable to build

@geoffreylitt I dAId it

We need a shorthand way of saying: "An AI did the work, but I vouch for the result" Saying "I did it" feels slightly sketchy, but saying "Claude did it" feels like avoiding responsibility

@pitdesi also watch out for "M" (mujer, not men). and holler if you have a free slot in BA, I'd love to take you to a good coffee shop!

I always get these wrong And I always think of Prince, but that doesn’t help

@pablo_aon Glorioso!

@dsaezgil Hace algunos años en Colalao del valle. Mejor verlos así. Abrazo!

@bsheldonx Si! We’ll see what we find

@dsaezgil Que hermosura. Now the only major miss will be the occasional decent Mexican meal 😃🌶️

@pablo_aon Hermosa estructura! Pobres bichos igual. Queda alguno aún no?

@dsaezgil La condorera. Diseñada por Jorge Newbery, primero en Plaza de Mayo y directo al zoo para alojar a los cóndores (muchos años de laburo en el ecoparque).

@bluelabel Gracias Ari! Hay que verse

@dsaezgil Gran nombre Coral! Te felicito! Abrazo.
