To drive digital innovation, do you attend demos by tech startups / companies?

I do and the impact is immediate about the kb. 

This is a must.  If you are only looking at the major vendors for innovation, you are missing out.  I've worked with a number of startups, been an advisor and then worked at one myself.  Opens your eyes to new ideas and if the product is interesting, you can provide feedback to help you solve your issues better.  Heck, there is a reason established vendors buy startups!  Get ahead of the curve and take that demo.  It's worth it! 

Yes, because I get the opportunity to see some of the product capabilities and whether the product has potential to help my organization. Many times I am not familiar with a product and getting to see the demos I can get a better understanding, like CASBs. Every organization should have CASBs installed.
