Create Own company, worked before in CISO position

If a person is working as Ciso before and know me since last 4 years and now create their own cloud base company in Uae just 6 months before.

Can any body recommend me to get the recommendation letter from this person who worked before at C Level position and know my work in detail and now he is running their own company which has only 6 months history presence.

Thanks.

I don’t see why not. If they know you personall and know your work - they should be able to give you recommendation, regardless of wether they have changed companies or not
