My job title says Growth Marketer. In practice, that means building outreach infrastructure nobody wants to set up, writing copy that doesn't sound like a bot, and occasionally posting on Reddit pretending to be just a guy with an opinion. I do both inbound and outbound, sometimes simultaneously, which is as chaotic as it sounds. So, what I've done so far - full funnel systems across 8+ early-stage SaaS brands. The whole stack, basically. Finding the right leads, reaching them across email, LinkedIn, Instagram, and Reddit, setting up the workflows so it doesn't all fall apart in week two, and making sure actual content and SEO holding the inbound side together. Usually, the only person orchestrating the whole function. I move fast, run experiments, most of them fail, and those get documented too. Self-critical enough to kill what isn't working and fast enough to replace it the same week. Most SaaS products click for me embarrassingly fast. Makes the copy better, the strategy less generic, saves a lot of back and forth. WordPress too, yes. Site auditing, indexing, troubleshooting- the unglamorous stuff. P.S. Reddit is underrated. Outbound is not dead. And I still think before automating things. Apparently that's rare now. If this sounds like the energy your growth needs, you know what to do.
