I've seen this pattern play out a hundred times. Ignore the noise in here. What you're describing is the equivalent of someone with a compound fracture asking a random passer-by for first aid advice. You need a surgeon, not a stranger with a band-aid.
Right now, you're at that inflection point where traction is everything. The first few months of advertising define the trajectory - spend wrong early and you've not only burned cash, you've poisoned your pixel and killed your data foundation. Roughly three out of four early-stage businesses never recover from that mistake. The macroeconomic environment is brutal for organic growth, you can't afford to learn by trial and error.
The right move is to find a team that lives and breathes early-stage acquisition. Someone who understands that your ad account architecture today sets the stage for scaling six months from now. But don't just grab the first "growth guru" you find. Look for someone who can explain why a certain audience strategy fits your unit economics - not just someone who talks about "hacking" or "blasting". They should have a documented process for testing, a grasp of your margins, and a willingness to be measured on results, not vanity metrics.
Ignore the DIY route. That's the road to joining the majority that doesn't make it past year two. Hire the specialist, but vet them like you're picking a co-founder.
