Nice discussion for #product-management.
Depends on what PMs you hire for platform products. Indeed should have affinity with tech products, for example devs turned product.
The same question you can ask for companies like Stripe, Twilio, Adyen, etc. etc.
What it requires is a lot of collaboration between PMs and engineers, with PMs heavily involved in talking to the users. When not familiar enough with the domain / tech stack / ..., then including an engineer on the platform team in that discussion can help bridging that gap. It should decrease over time.
