Investors say these 21 proptech startups are the most promising in their fields — and can even survive a housing downturn

• Insider asked 11 venture-capital investors to identify the top up-and-coming proptech startups.
• Investors nominated real-estate tech companies both in and outside of their own portfolios.

Funding for real-estate tech — more widely known as proptech — boomed in 2021. Startups of all stripes, including those that help buyers and renters score homes or help landlords manage properties and those that support firms in constructing and managing big buildings, attracted a record $32 billion.

But this year, interest rates spiked. Money became more expensive to borrow. Housing markets are slowing down. And layoffs at proptech companies have become common. That makes it harder for such startups to find customers and woo venture capitalists.

To identify the startups that deserve the most attention right now, we polled a dozen venture capitalists who invest in proptech. We asked them to name such companies — including at least one that isn't in their portfolio — and explain why their picks are on track for success.

Check out the full list of 21 proptechs that investors say are most promising.
