 Dear, First of all, I hope you are doing well during these difficult times. My name is Serbiev Rustam and I am a 22 years old professional mma fighter with a record of 7-2. I have been training in the past few years at AKA in San Jose under the guidance of the world famous "Javier Mendez" Currently I'm working towards my dream of fighting at the UFC! I have been fighting in many competitions in my career and my ambition and motivation is unstoppable. I've won several titles so far and one of them is from a championship in the USA. I am currently looking for a sponsor who wants to support my further career in exchange for value that I could contribute. I hope we would be able to come to an agreement so I could represent your company and help it further with its growth! Hope you have a nice day, Rustam Serbiev

How do you measure influencer marketing ROI when half the numbers social media gives you are vanity metrics?
