Building the best venue for private markets exposure.

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.

As reported in public records reported — not modeled.

Solid bars are reported offering amounts reported; hatched bars are the modeled post-money valuation est. — both on one shared scale so you can read raise-vs-worth at each round directly. Use the toggles to overlay data labels and the niche-peer / market average value lines.

No round amounts on record to chart.

No staged rounds to sequence.

Round size and date are reported; the stage label is inferred from round size. Valuation is modeled from stage benchmarks. Directional, not a quoted figure.

Not enough modeled valuation points to chart a trajectory.

Benchmarked against 1063 companies in Fintech. Each bar is a median (the middle company, not an average — outliers don't skew it). Two yardsticks: real money raised (reported on Form D) and modeled value (our estimate est.). These are whole-sector medians across all stages, except the per-stage row.

Raised more than 66% of sector peers (real $). Modeled value above 66% of peers (estimate).

Stage is inferred from round size est., not reported on the filing — a round's dollar size maps to a bucket: Pre-Seed <$1.0M · Seed $1.0M–$4.0M · Series A $4.0M–$15M · Series B $15M–$40M · Series C $40M–$100M · Series D+ $100M–$400M · Growth/Late >$400M.

Predictive signals are modeled est. from this company's own cadence and step-up, plus sector benchmarks — directional, not advice. Peer set and a CSV export live in your analyst workspace.

Alt-X is an official record sourced from the U.S. Securities and Exchange Commission (SEC). U.S. data is aggregated from SEC Form D filings.

Nearest neighbours across the whole database — matched on sector, stage and capital scale, and on shared operators (officers or directors named at both companies in public filings). A discovery shortlist, not a valuation cohort — verify before acting, the same way modeled figures are directional.

Matched by meaning, not labels — a local language model reads each company's name, sector and description and ranks the closest in that learned space. This catches look-alikes that cross sector boundaries; the structured list above explains its matches, this one trusts the text. Directional, like every modeled signal here.
