Please take the time to describe what it is you want. A good example:
Hi, my company is _________ and we are looking to partner with other companies and individuals to stream live content on Roku, please contact us at emailaddress@mycompany.com for more details.
Otherwise nobody knows what it is you are looking for and even if they can guess, it doesn't look like you are very serious because you did not even take the time to write a complete sentence nor introduce yourself.
