## About

Sublevel is the parent company behind Basement. One founder, one product:
everything Sublevel ships goes into Basement. Built in Miami and shipped
daily with an AI-native development pipeline.

## Founder

- **Luis Perrone**: Founder & CEO, based in Miami. 10+ years building
  consumer and infra software. Led the design systems team at UKG, shipped
  Helium Mobile past 500,000 subscribers, co-founded DewiCats.

## Product

- **Basement**: The one place for everything you shop, delivered as an iOS
  app and a multi-browser extension (Chrome, Arc, Brave, Safari).

Four pillars:

1. **The Closet** (live): Every purchase you make anywhere on the web,
   captured as you shop: the agent's own buys, the order-confirmation page
   of any store, even a photo of a paper receipt. Amazon knows what you
   bought on Amazon; only your browser sees the whole closet.
2. **The Stylist** (live): Baseling, an AI personal shopper that plans from
   what you already own, finds better prices across retailers, and tracks
   products and price drops.
3. **The Checkout** (live): Agentic checkout. You sign a spending budget
   with your passkey (an amount, an expiry, revocable anytime); that mandate
   mints a single-use, merchant-scoped virtual card. The agent checks out on
   the store's own site. It never uses your login and never touches your
   real card, which stays in a PCI vault.
4. **The Reviews** (roadmap): Product-page rooms where only real buyers can
   review, earning points merchants fund. Not yet shipped; the points,
   floors, and badges engine is live today.

## Thesis

A shopping app sees one store. Amazon sees Amazon. Your browser sees every
store you buy from, so it is the only place that can keep the record of
everything you own, and the only shopper that can act on it. Remember.
Know. Act.
