Since 2021, more than $43 billion has been invested in roughly 8,000 proptech companies, according to CB Insights. Proptech tools run the gamut, helping real estate firms with a variety of tasks including deal management, document management, investor relations, property and facilities management, and lease administration, among other tasks.

The harder question to figure out amid all of this is gauging how much market penetration various tools have and where the opportunities lie both for proptech firms looking to build market share and for traditional real estate firms who may be missing out on ways to improve processes and create differentiators with competitors.
