AskHN: Best X (Twitter) accounts to follow for GTM and startup launch insights?

I’m looking to get better at all things related to startup Go-To-Market.

I’d love to follow some solid X (Twitter) accounts that actually show their work: people who share checklists, breakdowns of what they did, what worked (or didn’t), and useful resources they’ve used along the way.

Basically, folks who don’t just drop one-liners, but walk you through the thinking behind a product launch or GTM playbook.

If you’ve got any accounts you learn from or enjoy, I’d really appreciate your recommendations. Thanks!
