Is it inappropriate to contact OU tutors after graduating?

Hi, I recently completed a Business Management degree in September 2025, I have some ideas and thoughts regarding some of the theories and concepts I studied and how I could combine a number of these and apply them to a new venture. I thought about perhaps emailing the tutors I had between 2023-2025 to discuss these ideas but I'm unsure if that's appropriate or not considering I have now graduated and some of these modules were obviously a couple of years ago. Cheers
