Hey all, it's been a while since I've shared openly on the growth & ops side of Studiotime, but I put out two very detailed playbooks or guides (with video walkthroughs) that I think you will find incredibly helpful:
How To Onboard Users & Optimize Marketplace Listings (Guide & Video Walkthrough)
How To Support Your Marketplace & Transactions (Guide & Video Walkthrough)
If you've just started an online marketplace, you'll find these super helpful and I've used it with quite a few other marketplaces to help build an initial framework for each, iterate, improve, and eventually build teams around.
Let me know if you have any specific questions!
