What others come to mind?
Hyper fragmented. 10% of the industry is owned by the industry giants (like Public Storage, which is a $39 billion publicly traded REIT), leaving 90% fragmented to small owners / independent businesses.
Very low productivity growth, very low innovation, poor management software options in the segment.
Someone could make a billion dollars just through consolidation of a tiny fraction of that mess, backed with better software and process.
Public Storage only has 5,600 employees and via their REIT structure spits off $1.4 billion in operating income every year.
The entire industry's value, going by what Public Storage is able to manage, is probably $1.2 to $1.5 trillion. And it's not going anywhere in the coming ~30 years, people are not going to suddenly stop storing their junk. It'll take an operator a lifetime to roll-up, consolidate even 1%-3% of the industry.
With computer usage being so widespread isn't it quite unlikely that at no point someone would have interest in computers and any particular industry that tried to combine their knowledge from both fields.
So in short, is there really any low hanging fruit left? Also could you elaborate on why you say that the construction industry is not using software efficiently.
