The Product Sandbox
Hi HN, After 15 years in product management, I realized there’s nowhere for Product Managers to actually practice, most learning focuses on theory, not doing. I built The Product Sandbox, a platform where PMs can practice real-world product scenarios, make decisions, and strengthen core skills through daily missions and challenges. It’s designed for aspiring to senior PMs who want to keep improving through real practice. I’d love feedback from this community on how you think PMs (or teams) can best build real-world experience outside of their day jobs. https://sandbox4pm.com
