Ask HN: Which B2B SaaS marketing playbook resources would you recommend?

hey thought I'd share these communities, thank me later

1: https://chat.whatsapp.com/Dy4ncep1xUo2l9QFpYm6mN These guys share a ton of free VALUE related to growth hacking that could be extremely beneficial for SAAS founders specifically , feel free to join and thank me later (join before it gets full)

2: https://microconf.com/microconf-connect Looks pretty good to network and socialise with likeminded individuals within SAAS , feel free to join.

3:https://www.saastock.com/join-the-community/ these guys probably have an amazing and big community of SAAS founders but overall more on learning how people made it, and did it, as well as strategy wise ,the first group is probably your best go.

Thanks.
