AI-first operator · Founder of Accrety · SF Bay Area & Medellín

AI won't
replace operators.
the ones who build it will.

Founder of Accrety, AI-first managed recruiting for US-LATAM teams, designed to run with one person and AI operating the rest. Accrety is the live proof. Seven years as co-founder and COO of Torre.ai. Forbes Top 50 Most Influential Angel Investors in Latin America. I ship practical AI in production, not slide decks, and run my own life on the same systems. Fifteen years operating companies, and 25 countries of fieldwork on how business actually gets done.

01  · What I do

First-principles.
Systems over
transactions.

I tear a business down to first principles, find the one lever that moves the most cash, and build the AI systems that pull it. I do this for my own companies first, which is why the work is proof and not a pitch.

i. Operate

Founder of Accrety. Co-founder at Torre.

Seven years scaling Torre as COO. Now I run Accrety as a one-person company with AI operating most of the work, on systems I built myself. When I say I run operations on AI, Accrety is the proof, not a slide deck.

One person + AI · The proof is in production
ii. Invest

Angel checks into early-stage founders.

Backing technical, mission-driven teams across LatAm and the US, alongside Angel Hub Ventures. I write checks where I can also be useful.

iii. Advise

Hands-on advisor to VC-backed founders.

25+ founders advised. Operator-grade help on the messy transitions: zero-to-one, first GTM motion, scaling ops with AI, the next round.

On building
and being useful.

№ 001
San Francisco
2026

I've spent fifteen years close to the people who build companies, first as one of them, then alongside them. The pattern I keep coming back to is unromantic and worth repeating: most problems aren't strategy problems. They're recursion and urgency problems.

What I trust most is first-principles thinking applied with speed. Strip the problem to its physics, find the cheapest test, ship it this week. These days I build that method into AI systems and run my own companies on them, so it isn't a theory I talk about. It's the operation I live in. The founders I admire, and the ones I work best with, operate the same way. They would rather be wrong on Tuesday than right next quarter.

If you're building something honest and you think a long-time operator could be useful, as an investor, advisor, or a frank second opinion, I'd love to hear from you.

Let's talk,
if it's worth it.

I read every message. The fastest way in is a short note about what you're building, why you, and what you'd want from a conversation.
