Alt-X

Alt-X addresses the persistent reliance on Excel in private-market investing. Annually, trillions of dollars in venture capital, real estate, and private equity are assessed using manual spreadsheet processes. This involves extracting data from diverse sources like PDFs and data rooms into inflexible models that have seen little fundamental innovation for decades.

Alt-X is developing an AI-driven infrastructure within Excel tailored for alternative assets. The platform ingests unstructured deal information and automatically transforms it into transparent and auditable Excel models. This allows analysts to create functional underwriting models in significantly less time, eliminating the need to manually reconstruct spreadsheets.

Alt-X extracts and maps critical KPIs such as ARR, growth, NOI, IRR, leverage, and cap rate directly into Excel. It then generates institutional-grade models, sensitivity analyses, and outputs suitable for investment committees, all while maintaining full editability and transparency.

Teams leveraging Alt-X experience a reduction in deal evaluation timelines by up to 70%, saving 30–50 analyst hours per deal, and enabling the screening of four times as many opportunities with the same resources. By automating extraction, modeling, and error detection within Excel, Alt-X transforms underwriting from a manual bottleneck into a scalable workflow.

Initially focusing on real estate and private equity, where Excel-based underwriting is particularly time-consuming, Alt-X is currently piloting its solution with family offices and private funds managing over $200 million in assets. Alt-X offers a SaaS pricing model, starting at $30 per month, with tiered options for teams and advanced workflows.

The market opportunity is substantial, with over $1.4 trillion in private-market deals underwritten globally each year and $25–30 billion allocated to diligence and analytics, predominantly through manual Excel-based methods. Alt-X aims to establish itself as the operating system for private-market investing within Excel, akin to the Bloomberg Terminal of the AI era.
