Alt-X: Automation for institutional-grade financial modeling in Excel

Automation for institutional-grade financial modeling in Excel

Alt-X is building the AI-native liquidity layer for private markets. Private markets have created trillions of dollars in value, yet remain fragmented, illiquid, and inaccessible. While public markets benefit from exchanges, market makers, brokerages, and data infrastructure, private markets still rely on brokers, spreadsheets, and manual workflows to connect buyers and sellers. Alt-X uses AI to automate the core functions required to make private assets liquid. We streamline diligence, valuation, investor matching, and transaction execution, reducing the friction that makes private-market transactions slow, expensive, and opaque today. Our initial focus is venture-backed secondaries. We source opportunities from founders, employees, and early investors while building a network of accredited investors seeking exposure to the world's most valuable private companies. Over time, we believe every private asset—from startup equity to private credit and alternative investments—will require modern liquidity infrastructure. Building trusted infrastructure for private markets is difficult. Transactions involve complex diligence, fragmented information, transfer restrictions, and significant compliance requirements. Alt-X is focused on creating systems that can support real transactions at scale, not just marketplace listings. Ryan Samadi (Stanford CS/AI, former Citadel commodities trader) and Michael Wachsman (Cornell CS, infrastructure engineer) are building Alt-X because they believe ownership of innovation should be more liquid, transparent, and accessible. Today, Alt-X has sourced over $1.5 million in transaction opportunities and assembled a network of 40 accredited investors representing hundreds of millions of dollars in investable assets. Our mission is to democratize ownership of innovation by building the financial infrastructure that private markets have never had.

Michael Wachsman

Founder

I am Co-Founder and CTO at Alt-X, where I lead engineering and architecture to build AI infrastructure for private-market investing. I joined because I saw how much manual analysis and fragmented deal data slow down investment teams, and now I’m focused on rethinking how this industry works from the ground up.

Why we built it

Ryan spent years in the hedge fund world and institutional finance watching the same thing happen on every deal: a 200-page offering memorandum lands, IC is in 48 hours, and someone is manually pulling numbers cell by cell into Excel building capital stacks, sizing debt, modeling cash flows, building waterfalls from scratch.

The biggest firms built proprietary infrastructure to solve this. Everyone else is still doing it by hand.

What Alt-X does

https://youtu.be/OqDnOfKzudk

Alt-X lives in Excel. Drop in your OM and it automatically builds your full underwriting model: sources and uses, senior debt sized to LTV and DSCR constraints, ten-year operating cash flows, exit cap sensitivity, full GP/LP waterfall with promote tiers.

Every number is cited back to the exact page and line of the source document. Every change needs your approval before it's applied. Not blind AI. Not manual modeling. Build fast and verify everything.

Team

Ryan studied CS at Stanford, worked at Citadel and previously was founding engineer of a $XXMM+ commodities startup. Michael published novel ML research at Cornell and built state-of-the-art AI security systems. Together, they've lived the pain of financial modeling and have the technical depth to fix it.
