How We Got Into Y Combinator
Three applications, three rejections, one acceptance — what changed between each YC attempt, what the interview was actually like, and what YC taught us about scaling DailyBot.
CTO at DailyBot (YC S21) · Builder of Digital Products
I build technology that empowers teams. CTO & Co-founder at DailyBot (YC S21), a collaboration platform where human teams and AI agents work together. 14+ years shipping digital products, from AI-powered platforms to open source tools.
Today I lead engineering at DailyBot (YC S21), a modern collaboration platform that enables human teams and AI agents to work together seamlessly. I focus on product strategy, AI-powered workflows, and reliable systems that help hybrid teams move faster.
My strengths are turning complex ideas into simple products, scaling engineering teams, and shipping end-to-end: architecture, execution, and iteration based on real user feedback.
I currently focus on AI applications, developer productivity, and high-impact products that combine speed, quality, and measurable business results.
I have led the development of a modern collaboration platform that enables both human teams and AI agents to work together seamlessly. It provides unified transparency and visibility into work across hybrid teams and intelligent workflows—supporting async standups, peer recognition, and AI agents reporting on progress—all inside Slack, Microsoft Teams, and Google Chat. In 2021, we were selected by Y Combinator, which accelerated our growth and reinforced our focus on customer satisfaction. 🚀

My journey through building and failing products at Rocka.co — what each failed experiment taught me, how I learned to recognize real PMF signals, and why DailyBot finally stuck.
Beyond DailyBot, I'm an entrepreneur and maker passionate about technology. I build side projects, explore AI, and contribute to open source — from Moltbot (AI on Raspberry Pi) to Syntro (AI-powered support) to SysPrompt (LLM prompt management). With 113+ repositories on GitHub, I believe the best way to learn is to build something real.

The complete story behind XergioAleX.com — from a one-page landing to a bilingual, AI-ready, performance-first personal platform. A deep dive into architecture, technology choices, and why Astro + Svelte is a killer combo for modern static sites.
I co-founded Pereira Tech Talks, a tech community dedicated to connecting professionals and sharing knowledge in Colombia. As a speaker, I've talked about Docker, serverless architectures, conversational AI, blockchain, and more at conferences and meetups across the region. The community has grown into a platform where developers, designers, and entrepreneurs connect, learn from each other, and push the boundaries of what's possible. I believe technology grows faster when we share what we learn — that's why I write this blog and speak at events.
As an enthusiastic trader, I have dedicated the last two years to training in the foreign exchange market (forex) and deepening my knowledge of algorithmic trading, with the goal of optimizing and automating my investment strategies. I am motivated by continuous learning and financial market research, always looking for new tools and approaches to improve my performance and make more informed decisions.
When I'm not building products, I'm exploring other passions. I love reading, especially science fiction — Isaac Asimov is one of my favorite authors — and films about time travel, dystopian futures, and space exploration. I study financial markets and algorithmic trading to understand the world of business from a different angle. I stay active through cycling, running, and basketball — sports keep me energized and disciplined. And I love discovering great food and sharing culinary finds. Life is better when you're curious about everything.
