Is there a UK sub for people trying to start their own business?

Sorry if this is the wrong place to ask.

I’m considering starting my own business and I’ve drawn up a fairly comprehensive business plan. I was just wondering if there is a UK based subreddit in which I can talk about it and ask questions. I was going to ask in r/UKPersonalFinance, but it feels like the wrong place as this isn’t about personal finance.

Any help would be appreciated. Hope you guys all have a great Tuesday!
