Questions & Answers

As answered by people managing Vapi and Altyst.

What makes your product unique?

Altyst's answer:

Altyst does more than summarize documents. Users can upload offering memorandums, rent rolls, T-12s, leases, and other property files and receive a live, editable commercial real estate underwriting model. Assumptions remain reviewable, calculations are handled by deterministic financial logic, and the analysis can be exported to Excel or polished PDF reports. Altyst combines the speed of AI with the transparency and control needed for real investment decisions.

Why should a person choose your product over its competitors?

Altyst's answer:

Traditional commercial real estate underwriting platforms can be expensive, complicated, and designed for large institutional teams, while general-purpose AI tools often stop at document summaries or one-off answers. Altyst is browser-based, starts at $12 per month, supports a wide range of property types, and turns source documents into a usable financial model in minutes. It provides serious underwriting capabilities without enterprise pricing, lengthy setup, or a sales process.

How would you describe the primary audience of your product?

Altyst's answer:

Altyst is built primarily for independent commercial real estate investors, brokers, analysts, developers, owner-operators, and small acquisition teams. It is especially useful for people evaluating their first few deals and professionals who need rigorous underwriting without a large analyst team or expensive enterprise software.

What's the story behind your product?

Altyst's answer:

Altyst grew out of firsthand experience in construction management and real estate private equity. Too much deal work involved manually copying numbers from offering memorandums, rent rolls, T-12s, and leases into spreadsheets, then spending hours checking that everything tied together. Altyst was created to automate that repetitive work while preserving the transparent assumptions, financial rigor, and control required to make an investment decision.

Which are the primary technologies used for building your product?

Altyst's answer:

Altyst uses Next.js and TypeScript on the frontend, with a Node.js and TypeScript backend. The platform runs on Vercel and Railway and uses PostgreSQL, Redis, and AWS S3 for its data and document infrastructure. It also integrates Stripe, Resend, Anthropic models, and a deterministic calculation engine built specifically for commercial real estate underwriting.

Who are some of the biggest customers of your product?

Altyst's answer:

Altyst is currently an early-stage, direct-to-consumer platform rather than a business built around a few large enterprise accounts. Its users include independent commercial real estate investors, brokers, analysts, developers, owner-operators, and small acquisition teams. Because Altyst serves individuals and smaller firms directly, it does not publicly rank or identify any single organization as its biggest customer.
