AI growth team for e-commerce brands

Boom builds the AI employee for e-commerce — an agent that manages every customer interaction across WhatsApp, Instagram, TikTok, Facebook, and web chat. It answers product questions, supports customers with orders, follows up on abandoned checkouts, restocks, and repeat purchases, and even runs marketing campaigns. Brands simply connect Boom to their store, and their AI agent instantly starts selling, supporting, and following up like a real team member — no setup or flow-building required. E-commerce is a $6T market where brands spend heavily to bring customers in, only to lose over 99% of them before checkout. Boom fixes that by turning every missed conversation into a sales opportunity. Our clients increase conversion rates and deliver a concierge-like buying experience at scale. We believe that in the near future, every online store will have AI employees managing sales and customer relationships — and Boom is building the platform that makes that possible.

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.

Boom AI: Your AI Growth Team for E-commerce Brands 🚀
See original launch post

TL;DR – Boom is your AI growth team for e-commerce that handles sales, support, and retention automatically. Most brands focus on bringing visitors to their site, only to lose 99% of them before checkout. Boom changes that. Our AI replies to customer questions instantly over Whatsapp, Instagram, Facebook, and Web Chat. We also proactively reach out to customers by reminding them about abandoned carts and making personalized product recommendations. We've already become a top-five sales channel for our first customers.

Most e-commerce brands don’t lose customers because of bad products. They lose them because no one replies fast enough. 56% of all customer interactions happen outside working hours, and most go unanswered.

Boom gives every brand its own AI sales, support, and marketing team that works 24/7. It answers product and order questions, follows up on abandoned checkouts, notifies customers when items are back in stock, and runs personalized campaigns that bring them back to buy again. There’s no setup required. Just install Boom, and we’ll handle everything. Then sit back and watch as your AI team starts working for you.

In a short time, Boom has already become a top-five sales channel for our first customers. By personalizing every conversation, it turns missed messages into sales and long-term customer relationships.

E-commerce is a six-trillion-dollar industry where most stores still lose 99% of visitors. Boom helps brands change that by making every interaction personal, instant, and effective.
