No public ranking sorts PropTech angels, so this list is in no particular order: Zach Aarons, Pete Flint, Spencer Rascoff and Roman Smolevskiy. NFX's Signal places Aarons, Flint and Rascoff among its top 2026 real estate seed investors, and Lenny's Newsletter names Smolevskiy. Rascoff's firm says it is not making new investments, so he is context, not a target.
PropTech is a thin market for pure angels. Most of the investors who write the earliest checks into real estate technology run a small fund or a firm built around the sector, and the public datasets reflect that. So this page names four people with verifiable ties to the category, says which source places each one, and leaves out anyone who could not be sourced. Where a source gives a check range, it is a third-party estimate rather than a promise.
Who are the active angel and early-stage investors in PropTech?
Two datasets do the heavy lifting here. Lenny's Newsletter, built with Crunchbase data and published in December 2024, ranked the most active US angels. NFX's Signal keeps a ranked list of 1,962 real estate and PropTech seed investors for 2026, though only the top eight names are visible without an account. Those eight include Brendan Wallace of Fifth Wall, Pete Flint, Spencer Rascoff and Zachary Aarons.
The four below are the individuals in those sources who come from the industry itself and have written early checks, as angels or through small funds. One of them, Rascoff, is listed because Signal places him there; his own firm says it is not currently investing, so treat him as context rather than a lead.
Zach Aarons
Aarons is co-founder and general partner of MetaProp. MetaProp's own biography says he began investing in early-stage PropTech companies in 2010, while working for the developer Millennium Partners, and that he became the most active angel investor in the space with more than 50 portfolio companies. That is the firm's claim about him, not an independent ranking. He founded MetaProp in 2015 and co-authored the book PropTech 101. Signal's profile lists a range of $100,000 to $1 million and a sweet spot of $1 million.
Pete Flint
Flint is a partner at NFX. NFX's team page describes him as co-founder and former CEO of Trulia, which merged with Zillow in 2015 in a deal that valued Trulia at $3.5 billion, and lists PropTech first among his focus areas. Signal shows a range of $500,000 to $5 million with a $2.5 million sweet spot, which puts him closer to a seed fund than a classic angel.
Spencer Rascoff
Rascoff is the founder and a general partner of 75 & Sunny. His firm's site says he co-founded Zillow, Hotwire, dot.LA and Pacaso, among other companies, and was Zillow's CEO for a decade. The same site says, as read in October 2026, that 75 & Sunny is not currently making new investments or new incubations and is supporting its existing portfolio companies, so he is not a target for a new pitch today. Signal still tags him as a founder angel, with a range of $100,000 to $5 million and a $1.5 million sweet spot, but it is a directory entry; the firm's own statement is the better guide to his current activity.
Roman Smolevskiy
Smolevskiy is the one name in Crunchbase's angel data who is explicit about the category. Lenny's Newsletter lists him eighth among the most active angels of 2024 and says he comes from the construction business and invests in PropTech, ConTech and RealTech, three categories he described himself. The same write-up says he also invested in SpaceX, Neuralink and xAI. No check size or portfolio count is given there, and no other primary source for him was found, so nothing further is claimed.
How is PropTech funding moving?
Context helps when you choose whom to approach. Crunchbase News reported that global real estate startups raised about $10.2 billion at seed through growth stage so far in 2025, down 57 percent from 2019, with deal count down 58.3 percent from the 2,722 deals of 2021. Capital is going mostly to companies in core workflows such as payments, closings and procurement, or to those with a clear return from automation and AI.
For an angel, that can cut two ways. Fewer deals can mean less competition for the good ones and less frothy valuations than at the peak. It can also mean follow-on rounds take longer, so a PropTech check should assume a long hold.
How should a PropTech founder approach these investors?
A few practical rules follow from the sources.
Match the check to the investor. Signal's ranges run from $100,000 to $5 million, so a pre-seed founder asking for $250,000 should expect a different answer from each of the people above. Pre-seed versus seed explains why.
Lead with the industry insight. All four come from real estate or construction, and they know the sales cycle, so show a customer in the market, not only a product demo.
Ask the angel-versus-fund question early. Flint invests through a fund, Aarons through a firm that grew out of his angel investing, and the source for Smolevskiy does not say; Rascoff's firm says it is not making new investments. Whether your check is personal or institutional changes follow-on and decision speed.
Warm introductions work best. Lenny's own advice is to find a mutual contact before a cold email.

Frequently Asked Questions
Q:Who is the most active PropTech angel investor?
No neutral ranking answers that. MetaProp's biography calls Zach Aarons the most active angel in the space, but that is a self-description. In Lenny's Newsletter, Roman Smolevskiy is the only investor whose stated focus is PropTech, ConTech and RealTech.
Q:Are the people on this list accepting pitches?
None of the sources promises a response, and Rascoff's firm, 75 & Sunny, says it is not currently making new investments. Signal offers intro paths through shared contacts, and Lenny's says the best investors favor warm introductions over cold email. Check the investor's current focus before you write.
Q:What check size do PropTech angels write?
Signal's third-party ranges run from $100,000 to $1 million for Aarons and $500,000 to $5 million for Flint. Rascoff's firm says it is not making new investments, and Smolevskiy's range is not public in the sources reviewed. Treat the ranges as starting points and confirm directly.
Q:Is PropTech a good sector for a first-time angel?
The sources do not rate it for first-time angels. Crunchbase News reports funding down 57 percent from 2019 and deal count down 58.3 percent from 2021, with capital going mostly to companies in core workflows such as payments, closings and procurement. Sales cycles and capital needs in real estate are long, and sector concentration is a portfolio choice, covered in the guide to diversifying an angel portfolio. This page is not investment advice.
