I got accepted into Y Combinator One month ago, I quit my job and lost my U.S. visa to build a big company. I was unemployed and without a home. So I started knocking on doors. Then something unexpected happened. While I was telling friends in San Francisco that I wanted to start something new, Pablo looked at me and said: “I want to start something with you.” We had worked together for a year at StackAI, solving complex AI challenges for enterprises. We knew how each other thought, built, and pushed through hard problems. We were a perfect match. We applied to YC at the very last minute. Two weeks later, on a Friday morning, we got that email, an invitation to an in-person interview in San Francisco… the following Monday. The only issue? We were both in Madrid! We booked a last-minute flight from Barcelona and landed Monday morning. Pablo even went to a wedding right before our flight, but that’s another story. The rest is history. Today, I’m beyond excited to share that Pablo and I are building Karumi (YC F25), a company you won’t forget. Stay tuned!

🤫 we’re hiring one person, the only requirement is to work hard and be smart. AI experience is a must. apply now, before our launch, you'll have less competition, still on time of living YC experience 🤫 only apply if it’s 3 AM, you’re building your AI product, and you still wake up at 8:30.

You have to apply to YC. We applied without thinking we were going to get in, and here we are. Just do it.

Yesterday, I failed miserably. Today I wanted to do the launch of my startup and we couldn’t, after many hours of work, there are no excuses. Back to works 🫡

After all the "performative" work. This is what we've been building. Hit "Demo Now" on our page - watch AI handle a product demo start to finish.

🙋 Are you going to kill my startup?

This is the reality of getting into YC. We started from nothing. 14 hours a day, 6 days a week. Revenue growing every week. Real customers paying for real value. You have no idea what’s coming.

Only in SF can you convince someone to come on a Saturday evening to grind this is the place

Hackerazo house in mission district!

✨This week, a group of young, hungry builders moved into the hacker house. They reminded me of myself 10 years ago, just getting started in tech, hacking late nights in Valencia.

As a founder, I struggle to be understood by my ex-girlfriends. Do all women need to spend most of their time with their partner?

btw we are hiring! we have to fill the rest of the chairs!! DM me for more information, Full Stack Engineers Frontend Engineers Product Designer 🎨

People saying this post is performative because I had to set up the tripod are losers who have never recorded a video. The real problem was the song; I didn’t know what song to add.

How do you handle this? Investors, interested leads, and customer support are reaching out through every possible contact I have: - Personal email - Company email - LinkedIn - X - Bookface - Personal phone I'm going crazy - If I see a message and I don't answer right away, I lose it.
