That would be great if you could get it. Also you don’t need it in new company letter head as you never worked for the new company, just get it in plain paper with his signature and designation and get it notarized. If he has any business card from his previous company you can attach it too as a proof.Alright. Thanks. We were paid in cash. It was a start up. The company metamorphosised into a big company now though. Will it be appropriate to tell the ceo to write with his new company's letterhead and maybe he explain that his former startup business is now the new one?
