About Astor

A better way to underwrite real estate at scale.

Astor is a Clay-style table for US real-estate investors — define a financial model once in a typed, unit-aware language, run it as a filter across millions of properties, and publish the result as a live underwriting document.

Why we built this

The hardest part of real estate investing isn't finding deals — it's filtering thousands of leads down to the ten worth underwriting. Most operators do this in spreadsheets: one model, copy-pasted across hundreds of rows, updated by hand when cap rates shift.

Astor replaces that workflow. Write your financial model once in a typed DSL. Compile it to SQL. Run it across every property in a market in seconds. The result is a live, filterable grid — ranked by the metrics that matter to you, not to Zillow.

The wedge no competitor offers: filter on a computed metric across a whole market, re-ranked by financing profile. Ask “show me every multifamily in Memphis where my model produces 9%+ cash-on-cash at today's rates” — and get the answer in real time.

Our values

Built for operators

Every feature we ship is tested against real underwriting decisions. If it doesn't save hours or surface better deals, it doesn't ship.

One model, one engine

Write a financial model once. Filter millions of properties with it. Publish it as a live underwriting doc. No export, no copy-paste, no drift.

Typed and unit-aware

Numbers carry units. The DSL enforces them. LTV is always a ratio. Cap rate is always a percentage. Mistakes surface at parse time, not in a deal memo.

Trust through transparency

Every computed column shows its formula. Every filter shows its logic. Investors and lenders see the same numbers and the same math.
