I sent an entrepreneur a video about a situation which could give his new business an advantage. He thanked me and I asked if the video proves useful to him. He told me it doesn't and told me his reasons. I then told him "actually if you do X, it could get you Y", and got no response.

We used to work at the same place and I got some chances to "talk business" with him. I'm not a businessman as he is, that's for sure. I have no personal experience in entrepreneurship. I only intended to give my thought out and I did not mean to insult his quality as a businessman, as I am sure he knows allot of things I don't.
My personal interest is to see and perhaps enter the world of entrepreneurship.
I mostly get anxious or irritated when people do not respond to what I write. This time I got anxious. I didn't mean to be patronizing if that's even the word.

How could I have communicated with him better...?
Or did I even do anything wrong or not good enough?

Meh I don't really care right now. I think it's his loss for not willing to communicate with me, at least for now.
Though sometimes I get anxious and need reassurance

That was thoughtful of you to send him a video of something that could potentially improve his business.

I probably wouldn't be giving advice to someone who has an expertise or experience that I know nothing about, if you know what I mean.

You may have given him a great idea he chooses to dismiss because he will use it and give you no credit. It may be he is just didn't want to get into a whole dialogue with you about it, so he ignored you, which was rude. It may be he gets lots of unsolicited contacts from people, so he ignores them. It may be simply he has poor social skills.

You didn't do anything wrong. But you did send him unsolicited advice, which is a slippery slope. He may have been suspicious what is in it for you. He may have been afraid to comment because of fear of getting sued for whatever reason.

People don't always want to hear professional advice from people who aren't familiar with the field. If someone sends me a video about my job I'd say thanks (and that's what your friend did), but I would be under no obligation to follow that advice if it's not useful to me.

I don't see how he ignored him. He thanked him for the video. But when op started pressuring his friend on usefulness of the video then he explained that it's not useful. I see that he didn't give op a response he wanted.

I've worked with a lot of entrepreneurs and startups. Something to know about entrepreneurs is that they tend to generate a dozen ideas a day and while they tend to take advice and inspiration from everything around them, they also receive a lot of advice they have to filter through and won't have the time or patience to go through all of it.

My advice for you if you're seriously entering entrepreneurship is to learn how to grow some thicker skin. People will think fast and talk faster, and often won't take the time to respond to every single thing they're emailed and sent. You'll come to learn that it's not personal and that entrepreneurs are very social in person, but won't have the time to remember and respond to everything else.
