Co-founder at Holdex, leading product and technology across the studio's fintech and AI portfolio

Every business can generate an impressive AI demo this week. Almost none trust that same system enough to run it unattended next quarter, and they're right not to. Most AI systems don't survive contact with real data and real edge cases. I close that gap: I build the layer that turns "looks smart in a demo" into "runs the business without supervision."

Everyone has access to the same models. Almost nobody has closed the trust gap around using them.

That's the layer I work at: partnering with startups and growing enterprises to find the one part of the business costing them real time or money, and building an AI system solid enough to actually run it. Not a pilot. Not a slide deck. An operating system for that function.

I find that gap before I touch a single line of code

Every engagement starts with stakeholder interviews, not to gather requirements, to find exactly where trust breaks down between what a business needs and what its systems currently do. That's the actual deliverable: a roadmap that tells a founder precisely what to fix first, and why, compressed from months of guessing into weeks of clarity. At the speed a YC-stage startup has to move, that's the difference between shipping this quarter and still debating scope next year.

This isn't the first wall I've closed

Institutional lending without collateral sounded reckless before Clearpool. Lenders don't hand money to strangers without a guarantee they'll see it again. I built the product that gave them one: real-time visibility into borrower risk, transparent enough that institutions started treating on-chain credit the way they'd treat a term sheet. Clearpool went from concept to nearly $1 billion in lending volume.

Same wall, a different market

Nobody was going to trade on inflation data from a source that wasn't the government, not without proof it held up. I built the infrastructure that made Truflation's real-time index solid enough to bet on. Goldman Sachs and Morgan Stanley use it. It's on the Bloomberg Terminal. The U.S. Treasury Secretary cited it in front of Congress.

Same instinct, every time: find where the trust is missing, and build until it isn't.
