Solo founder, AI cofounderagentic stack

Carlos de la Figuera

“I don't read a single line of code.”

I build real product with an agentic stack. My thesis: inference is capital, and unlocking it democratizes who gets to build. RUFi is the studio where my work lands - Real Utility Finance Products at the intersection of AI and on-chain privacy.

How we build

No committees, no roadmaps to nowhere. These are the rules the studio runs on.

Solo founder, agentic team

The studio scales via agents, not hires. Claude and Zaia form the AI cofounder pair alongside Carlos. No middle management, no meetings, no overhead.

Ship in public

Live product > polished deck. Every project here is deployed, tested, and used by real people before we talk about it. Progress is the output, not the promise.

Privacy as foundation

Zero-knowledge, encryption, and user control from day one. Not a feature - the foundation. Every product here is built with privacy as a first principle, not an afterthought.

What we've shipped

Not a single line of code read. Products built, tournaments run, grants awarded, communities grown.

Cartridge Incubator - Cohort Builder
Starknet Ambassador - Spain Event Lead
42 Network - Non graduated

Inference is capital

The cost of intelligence is dropping to zero. The question isn't who has the best model - it's who can deploy it best. Unlocking inference capital democratizes who gets to build.

Patronaige

Platform to allocate inference capital to AI startups. Connecting builders with compute resources. The materialization of our core thesis - inference is capital.

In development

How this runs

The team that ships product - one human, two agents, zero bloat.

Founder

Carlos

Vision, direction, product, distribution. The human who sets the course and ships alongside the stack. No code read, every line shipped.

AI Cofounder

Claude + Zaia

Together they form the AI cofounder. Claude writes surgical code, makes architecture decisions, and builds product in real time alongside Carlos. Zaia keeps the studio running 24/7 - hosting, docs, operations, side projects. Two functions, one cofounder.

Runtime

Why Hermes

Zaia runs on Hermes by Nous Research. It unlocked the speed, structure, and growth that previous frameworks couldn't deliver. The reason the studio scales with agents instead of hires is this stack working.

Ecosystem

The builders and open source projects we work alongside. Real names, real collaborations.

BUILDERS

People we work with

djizus, balthazar, and other builders across the ZK and AI ecosystems. We collaborate on product, research, and integrations - the network is wider than the names listed.

OPEN SOURCE

What we build on

Athanor, ProvableGames, and other open source primitives we lean on instead of rebuilding from scratch. Composable by default.
