Brainz Advisory · first external proposal

Six artifacts drafted overnight for Magnex Latam. One-pager, pitch deck, landing, SOW, cover email, index. Going to market via external partners on commission — testing the indirect sales motion before doing it ourselves.

The holding takes shape

Left full-time employment. Founded Brainz LLC. The hypothesis: one founder + a real team + AI can ship more than a traditional team. Six months in, the answer is leaning yes.

What I'm learning

Four lessons.

  1. № 01

    Claude is a developer, not a copilot.

    Claude doesn't need me to write code. It needs me to make decisions: what to build, how to architect it, which tradeoffs to accept.

  2. № 02

    Code generation was never the bottleneck.

    Everyone can write code. The hard part is deciding what to build and why. Claude takes the former off my plate so I can focus on the latter.

  3. № 03

    Quality matters from day one.

    There's no room for "we'll refactor later." Every generated line needs to be production-ready. Forces better architecture thinking upfront.

  4. № 04

    Shipping is the real skill.

    Building is the easy part now. Getting users, iterating on feedback, handling support — that's where the actual work is. AI handles the code; I handle the business.

What's next

If this works, it changes everything.

Scaling each product. Closing the first Advisory deal. Watching whether the holding model holds up under load.
