When affordable housing construction tech company Veev started 15 years ago, it probably wasn't with the thought of an ultimate collapse after $597 million in raised funds with investors like JLL Spark, according to Crunchbase.

California headquarters and R&D in Israel, the company's website is still up, stating, "Our process includes digital architectural & structural design, full panelized manufacturing and on-site installation." It was supposed to be a time- and money-saving approach to residential building at scale.

But as experience with tech companies shows, waves of funding and then reconsideration can result in companies left to sink. As Mercury News reported several weeks ago, Veev achieved unicorn status in 2022.
