Product Description
Alt-X offers an AI Excel Plugin that automates the creation of institutional underwriting models from real estate deal documents, such as offering memorandums and datarooms. Key features include the ability to transform lengthy documents (up to 200 pages) into fully built, auditable models in Excel within seconds. Each figure in the model is traceable back to the exact page and line of the source document, ensuring transparency and verification. This automation significantly reduces the manual effort involved in financial modeling, allowing users to focus on decision-making rather than data entry. The product is particularly beneficial for real estate private equity analysts, private equity associates, and venture capital analysts, as it streamlines the underwriting process and enhances accuracy.
