Recommendation letter from a Product Led company

[Irfanlibra2017]

Hi,

I am in the process of preparing GTV Endorsement case. I am getting recommendation letter from 2 of my previous employers and 1 professional from a different company that worked with me in the past 5 years on a joint venture.

TechNation/Home Office requirement is that they want recommendation letter from a product led company rather services based company. One company from my previous experience is developing a product that is a pure innovation of the company and still under development. There is no mention of the the product on the company website. How can i ask my company to write my recommendation letter so that TechNation/HomeOffice will accept it. In the letter they will explain my direct contribution to the products technology and my innovative achievements during the development process. Will that be sufficient?
