What is the best growth channel for your startup?

- I'm a B2B tech/SaaS marketer. Organic LinkedIn is the best channel for me. - For my enterprise clients, the best channels are personal founders' network, organic LinkedIn, visiting podcasts/conferences, and different partnerships. - For clients with cheap B2B products, the best channels are LinkedIn, building in public on X, integrations with other tools, and free side tools/templates. What about you?
