Hi, I'm Carlos Velasco
building the next gen of consumer AI & Crypto.
Founder-engineer in YS24 and HF0. Ex-Venmo
Since 2015, I've built full-stack web applications for the fintech space—specializing in banking, credit-card, and mobile-payment solutions for startups. Today, I'm leveraging AI to accelerate usable product delivery.
Over the past two years, I’ve been in San Francisco as part of Y Combinator and HF0, launching products from 0 to 1. I’m obsessed with the future of consumer AI and how the 10x factor is transforming both the industry and the consumer.
