Honestly, all of it matters - positioning, targeting, distribution. But I'd argue the real grind isn't just picking channels, it's building genuine traction early on.
What's worked for me is stacking a cross-channel mix that feels human. Stop obsessing over followers or vanity metrics. Get onto social platforms where your actual audience breathes - Twitter, Reddit, even niche Discord servers - and pair that with launch platforms like Product Hunt or Microlaunch. But the secret sauce? Creator partnerships. Find micro-influencers who actually give a toss about your product, negotiate UGC deals that feel like collaborations, not transactions.
Run small tests across each channel, measure real engagement (not just clicks), and double down on what actually moves the needle. If conversion's rubbish, it's often a targeting or positioning issue, not the channel itself. Keep iterating, keep building relationships. First $1k MRR comes faster when people feel you're part of their community, not just another brand screaming for attention.
