What are good conferences to attend related to product marketing?

SVPG (http://www.svpg.com) recently announced this one:

Announcing: How To Rethink Product Marketing – San Francisco, April 11

My partner, Martina Lauchengco, only puts on two public product marketing workshops a year. Product Marketers are an essential partner in making products successful. This workshop will improve product marketing skills, bring more definition to the role at a company, and train up product managers who want to understand more about bringing products to market.

I've attended this and thought it was helpful although many things she described were not covered under product marketing at my company. I did find it valuable as a thought starter about how other companies may be doing things and she shares all the materials afterward.

Productmarketingcommunity.com is setting up product marketing conferences around the US. Definitely check them out.

To be honest I've never really seen one. The SF Product Marketing Meetup is the closest thing I've seen - https://www.meetup.com/product-marketing

Product Marketing Summit (various locations): https://productmarketingworld.com/ 

I would defenitly check: https://productmarketingalliance.com/events/.
If you become a member, you can watch all previous summits they had in different countries around the world.

There is a product conference (Project Product) in the Midwest specifically for product marketing and product management professionals and uniting the two together. The second annual event is March 10-11, 2020. Day 1 is a full-day conference and day 2 is a half-day with interactive workshops. https://projectproduct.com/
