Here's what six startup execs have to say about the big CEO shakeup at Google Cloud

Google has had a hard time penetrating the enterprise marketplace. You need a go-to-market engine. Google has been trying, but it has not made progress. If you compete with AWS and Microsoft Azure, then how do you go from the DNA of being consumer-centric to enterprise-centric? Diane was a victim of that, I suspect. [Kurian] was a powerhouse for go-to-market, so he'll bring that to the table.

I think Diane came in to do what Google wanted her to do, to work on the business side of Google. Google is working to catch up. I hope the new CEO will take that even further. They're saying, let's up the level to be on par with other cloud offerings.

I said, wow, when it happened. Diane Greene is an immensely competent leader. She can't leave a job without it being big news. She's so competent, well-known and respected. Thomas Kurian was known as the architect of Oracle's roadmap for a long time. For him to step down and move to Google is also a remarkable shift. Google doesn't know how to sell and it certainly doesn't know how to sell to enterprises, which means enterprise sales and having customer intimacy, not thinking you're smarter than the customer.

Google is the #3 in the cloud for sure. Diane did an amazing job bringing it together. It will be interesting to see how Thomas takes his enterprise background to bring it to the next level.

With Diane Greene, they had someone who was really well respected for understanding enterprise. Thomas has very much the same reputation. It signals they're even more interested in penetrating enterprise.
