BIO
I’m the Co-Founder and CEO of Boom, where we’re building the AI employee layer for e-commerce: virtual agents that help brands close more sales by automating customer interactions. Before this, I dropped out of college to build Atrato (YC W21), one of Latin America’s leading Buy Now Pay Later companies, which I scaled from 0 to ~$20M in annualized revenue before it was acquired. I started as CTO and became CEO, which made learn how to sell, lead, and scale.
