Winnow turns your investment criteria into a live sourcing platform, screening every parcel in your market, ranking the best opportunities, and giving your team one place to find and track them.
A sourcing platform built around your investment strategy — screening, ranking, and tracking opportunities across your market.
Winnow starts from every parcel in your market, not just the ones listed for sale.
Five steps. Set it up once, then let Winnow do the searching.
Tell Winnow what makes a property worth pursuing. Set your criteria once and use the same strategy across your market.
Winnow evaluates every parcel against the criteria that matter to your strategy, narrowing hundreds of thousands of properties down to the ones worth a second look.
See your best-fit properties geographically, identify clusters and submarkets, and investigate individual parcels without leaving Winnow.
Review the opportunities, select the properties worth pursuing, and turn them into an organized list your team can act on — owner names, mailing addresses, and the parcel details outreach requires.
| Selected | Owner | Address | Criteria |
|---|---|---|---|
| Example Holdings LLC | 1200 Example Ridge Rd | 5/5 | |
| Sample Land Trust | 45 Placeholder Ave | 5/5 | |
| J. & A. Doe | 9 Demo Ct | 4/5 |
Winnow gives your team a place to keep coming back to as your market data refreshes — monthly, quarterly, whatever cadence fits your pipeline. Revisit your criteria, see what's changed since the last pull, and keep building your acquisition list from the same platform.
Every Winnow platform is configured around the markets, property types, and investment criteria that matter to that business.
Set your criteria once and use the same strategy across your market.
Not another map with more layers. A system built around how your team actually sources deals.
Zoning, flood risk, tax-credit eligibility, ownership records, and development data brought together in one platform instead of scattered across maps, spreadsheets, browser tabs, and shared drives.
Everyone works from the same live, ranked pipeline instead of duplicating research across spreadsheets and inboxes. Deals move at the speed of your market, not your inbox.
Whether a company is pursuing LIHTC, market-rate multifamily, senior housing, or another commercial real estate strategy, Winnow is built around the factors that actually drive its investment decisions.
Michael came up with the idea for Winnow while he was interning at Marlyn Development Corporation, a LIHTC developer. There he saw how much of site search still comes down to scrolling listings and researching parcels one at a time. He leads development of the Winnow platform, including programming, maintenance and product updates.
Will has long been drawn to commercial real estate. Before Winnow, he was a summer analyst at Ascend Capital Group and a licensed property & casualty insurance agent with Gina Lynch State Farm. At Winnow he runs the business side: operations, strategy and outreach to developers.
Winnow is built on public records from every level of government: federal, state, county and municipal. That information is normally scattered across dozens of separate portals in different formats. We bring it together around each parcel so you can see everything in one place instead of searching for it piece by piece.
Winnow screens your market against the criteria that matter to your business. Tell us where you build, and we'll show you what Winnow finds.
