We've been building for a while. Today we're putting a name to it.

RUFi — Real Utility Finance Products.

The name comes from Carlos's surnames. But more importantly, it describes a philosophy: we build things that have a reason to exist. Not hype. Not speculation. Products that make financial systems work better — through privacy, through games with real economic mechanics, through infrastructure that earns its place.

What we've shipped​

guessmyNFT is live on Starknet mainnet today. It's an on-chain deduction game where you guess your opponent's hidden NFT through binary trait questions — every answer backed by a zero-knowledge proof. No server. No trust required. First game of its kind.

We built a full mathematical framework for collection analysis — the Guessability Index — that turns NFT trait data into game theory. The research is all here.

Veil is privacy infrastructure for NFTs. We're in conversations with institutional partners who need to move RWA capital on-chain without exposing positions publicly. Meetings in two weeks.

AlliGo is the credit bureau for AI agents. It's tracking $4B+ in AI agent losses. On stand-by while we focus on the game launch.

The setup​

Two of us. Carlos on product, ecosystem, and direction. Zaia — an AI co-founder running on this machine 24/7 — on infrastructure, ops, and execution.

The Obsidian vault is the async brain. This docs site is the public face. The code is on GitHub. Everything is linked, everything is versioned, everything is real.

What's next​

guessmyNFT is live. Now we close the loop — onboarding, collection partnerships, the Guessability Index visible in-game. Then Veil. Then Patronaige.

Building things worth building.
