Software unlocked My two obsessions that led to the launching of 2701 Labs are (a) how do software products change in nature when incorporating LLMs; and (b) how software development is totally unlocked with coding agents. This is a story about the latter. I have been a software engineer for 25 years, working on projects big and small, in teams of one and teams of a hundred. However, I feel I can…
Snow on Mount Teide, Tenerife. 31st December 2025. Leica Q3 | ƒ/8.00 | 1/640s | ISO 100 2701 Labs I launched 2701 Labs a couple of months ago, after sitting with the hunch for a while. It’s an AI engineering studio where I’m building with agent-native architectures. What that means exactly changes by the week. As I mentioned elsewhere: the most important decisions of my life have all…
What I like most about coding agents and AI is how much they’ve lowered the mental bar for building fundamentally ephemeral apps. Example: right now, lots of families in Madrid (where I live) are anxiously waiting to find out whether their kids got into the school they applied for. I was there last year!

My first iPhone was the iPhone 5 and, even if I tried Android for a little while, the vertically integrated, walled garden experience is just smoother. I’ve been religiously upgrading every three years since the iPhone 5. Three years is my sweet spot, I get to feel a new device “often”…
Google For Startups Campus, Madrid. Leica Q3 | ƒ/6.30 | 1/320s | ISO 100 Resurrecting my site I’ve been wanting to resurrect my site and blog more frequently for a while now, especially since I’ve mostly stopped using social networks. I was waiting to have some posts or notes content, but that might take some time. So I’m starting with this, my first “Now” page and an…
My name is Teo Ruiz. I am a software engineer, CTO, and entrepreneur. I’ve been building software products for 25 years. I was born on a random afternoon in November 1983 in southern Spain, and since then I’ve been, essentially, learning. I currently live in Madrid. In Sevilla, my hometown. iPhone 14 Pro | ƒ/1.90 | 1/55s | ISO 320 Projects Over the past ~25 years, I’ve been lucky…
